  • Why is my dual-boot Ubuntu partition showing up as a peripheral "root.disk"?

    - by Don
    I recently installed Ubuntu 12.04, which I had been booting from a usb key, as a dual-boot on my machine running Windows 7. From what I had read online while researching, I was prepared to have to shrink the Windows partition and all that. But I never had to - it really was just a few clicks here and there and it was installed. I'm still pretty confused about it, but whatever, it worked, and the two peacefully coexist on my machine, and I have broken things to fix before I worry about fixing unbroken things. So yesterday I got it in my head to look at my partitions (I was considering making an all new partition to install the Windows 8 Release Preview). What I saw confused me. Here's a screenshot of the disk utility. At this moment, there is nothing connected to my computer, and nothing in any of the optical drives/ports/card readers/etc. Can you help me figure out what's going on here? Don's Machine is, I believe, my Windows partition - that's the name I assigned my machine from Windows Explorer. PQSERVICE is from what I can find online also Windows, but having to do with backup. And SYSTEM REQUIRED, if I browse it in Ubuntu, is definitely something to do with booting, and I believe it is also Windows'. According to the sizes shown, those three together should use up my 500 GB HD. Then further down, as a "peripheral device", it lists that 31 GB disk. This is obviously my Ubuntu (Model:Linux Loop:root.disk), but why is it showing up as a peripheral? So, to sum up those questions and to add some more random ones I had: Why is Ubuntu showing up as a peripheral device? If the Windows sections take up all 500 GB, where does Ubuntu live? If I renamed the disk partitions, would my life become a nightmare (seriously - can I safely rename them)? Why didn't I have to resize the Windows partition in the first place? Would giving Ubuntu more space improve its performance (it hangs alot)? Is it possible to have a partition for each OS (Windows 7 & 8, Ubuntu), a partition for files, and a separate partition for backups? Is this towards the good or bad idea end of the spectrum? @Elfy, would that explain why it keeps hanging? I guess I'll backup my files, rip it out, and reinstall it correctly later on today.

  • How to convert ext3 partition to use encrypted file system without loosing data?

    - by User1
    My embedded Linux device have 2 partitions: small root partition containing OS. big data partition which uses ext3 I want to encrypt the data partition by using encrypted file system. I don't want loose any data of the partition. Size of the root partition is too small to hold all data of the data partition. It is not possible to use any external data storage. Is there any tools that can convert filesystem of the data partition from ext3 to encrypted fs without copying all files to other place?

  • How to install Win7 over top of WinXP partition?

    - by Zeno
    I have a 2TB hard drive with 2 partitions on it, one a C drive for WinXP and another for extra space. I have a Win7 Pro install DVD and I have formatted that C drive via the DVD; it is now a blank "Primary" partition. I attempted to go through the Win7 setup and install it on that partition, but it's giving me an error: Setup unable to create new system partition or locate existing system partition. See setup log files for more info Googling around leads me to believe the entire drive has to be "cleaned" (diskpart) but that would wipe the entire other non-OS partition and I need to keep that data. How can I install Win7 on this blank partition without losing data on the other partition?

  • Will multivariate (A/B) testing applied with 302 redirects to a subdomain affect my Google ranking?

    - by Lior
    I want to do an A B test of an entire site for a new design and UX with only slight changes in content (a big brand site that has good Google rankings for many generic keywords. My idea of implementation is doing a 302 redirect to the new version (placing it on www1 subdomain) and allowing only user agents of known browsers to pass. The test version will have disallow all in the robots text. Will Google treat this favorably or do I have to use Google Website Optimizer (which will give me tracking headaches)?

  • Will you install software on the same partition as Windows system?

    - by Tim
    I was wondering if you always install software on the same partition as Windows 7 system? What kinds of software do you install on the same partition as Windows system? What kinds of software you install on another partition? If you install software on another partition, do you install them on a dedicated partition to these software? Or do you install them on the same partition as data (personal data)? How do you plan the sizes for the partition(s) in either case? What are to consider when making plans about the above questions? The software I am installing include: Matlab, Mathematica, IDEs, compilers or Interpreters for C++, C, Java, R, Python, Perl, Lisp, Latex, and database. Mainly for programming and typesetting kinds of studies and projects.

  • Where's the Swap File/Partition?

    - by chrisbunney
    I'm investigating the virtual memory configuration of a Debian based Amazon EC2 instance, and as my background isn't in system admin, I'm slightly confused by what I'm seeing. We're using MongoDB, and the monitoring server we have indicates that the Mongo process is using about 20GB of swap space, however I can't figure out where this is located on the server. As far as I can tell from using the various suggested methods from Google, there is either a much smaller amount, or none at all. top indicates that there is 1.8GB of swap memory: top - 15:35:21 up 6 days, 3:23, 1 user, load average: 1.60, 1.43, 1.37 Tasks: 47 total, 2 running, 45 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 1.3%sy, 0.0%ni, 14.7%id, 83.8%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 3928924k total, 2855572k used, 1073352k free, 640564k buffers Swap: 0k total, 0k used, 0k free, 1887788k cached swapon -s doesn't seem to think there's any swap space: Filename Type Size Used Priority free -m doesn't think there's any swap either: total used free shared buffers cached Mem: 3836 3663 172 0 626 2701 -/+ buffers/cache: 336 3500 Swap: 0 0 0 And neither does vmstat: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 3 0 66224 641372 2874744 0 0 21 5012 21 33 2 2 76 19 But cat /etc/fstab thinks there is a swap partition: /dev/xvda1 / ext3 defaults 1 1 /dev/xvda2 /mnt ext3 defaults 0 0 /dev/xvda3 swap swap defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 However df -k gives no indication of the xvda3 partition: Filesystem 1K-blocks Used Available Use% Mounted on /dev/xvda1 16513960 15675324 0 100% / tmpfs 1964460 8 1964452 1% /lib/init/rw udev 1914148 28 1914120 1% /dev tmpfs 1964460 4 1964456 1% /dev/shm So I really don't know what to make of this, because I appear to have a process using about 10 times more virtual memory than what might be available, and I have no idea where this virtual memory is on the system. I'm probably misinterpreting the output of the tools, so I'd be grateful if someone would be able to set me straight: What have I got wrong, what's the right interpretation, and how do you reach that interpretation? EDIT0: We use 10gen's MMS for monitoring the database, the relevant section for memory from the last data point is: "mem": { "virtual": 20749, "bits": 64, "supported": true, "mappedWithJournal": 20376, "mapped": 10188, "resident": 1219 }, This JSON is specific to the database process (I believe) rather than the system as a whole. fdisk -l /dev/xvda outputs... nothing?

  • Disk Partitioning problem with fdisk.

    - by MA1
    Currently i am using fdisk to create/resize windows partitions. Following is a sample input script to fdisk to create/resize windows partitions: fdisk /dev/sda < partInput the contents of partInput are as follows: d #delete the partition 3 #partition number to be deleted n #add a new partition p #primary: type of new partition 3 #new partition number 18804 #start cylinder of new partition 77433 #end cylinder of new partition t #change the type of partition 3 #partition number whose type(filesystem) is to be changed 7 #HPFS/NTFS: partition type(filesystem) n #add a new partition p #primary: type of partition 77434 #first cylinder of new partition 77825 #end cylinder new partition w #write all the above changes As you see in the above input we are using cylinders for start and end. Earlier i am using sectors as unit and everything is working fine but getting problems when partitioning a 1.5TB hard drive. Then i changed the unit to cylinders but it is working on some machines not all. On some machines fdisk failed to create the partition table correctly. So, i am thinking to move to parted if there is no way to do the above using fdisk. Please also tell me how to correctly convert sectors to cylinders? How to perform all the above steps using parted without losing the data OR how to use fdisk correctly?

  • Can't create system image. 0x80780119 error after upgrade from 8 to 8.1

    - by cichy202
    I have upgraded my Windows 8 PC to 8.1 yesterday and it seemed like everything is working fine until I tried to create System Image. I got an error 0x80780119 saying that there is to little space on one of the partitions. I started looking into this problem and indeed one of the partitions does not meet the requirements. There are following partitions on my drive: DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Recovery 300 MB 1024 KB Partition 2 System 100 MB 301 MB Partition 3 Reserved 128 MB 401 MB Partition 4 Primary 74 GB 529 MB Partition 5 Primary 390 GB 75 GB Partition 1 has only 13MB free space. Partition 2 has 70MB free space, partition 3 is MSFTRES, partition 4 is my C drive with around 35GB free and partition 5 is not included in system image. Partitions were create like this during installation of Windows 8 - clean install from scratch. I am using UEFI so the drive is GPT formatted. So I thought, OK I can resize my C drive a little, move the partitions and expand the 1st one. I tried using GParted but it is not able to move the MSFTRES partition. It does not recognize the file system on it. So the question is: Is it possible to "clean up" the 1st partition in anyway? If not, is there anything special about MSFTRES partition? Or can I just remove it and create it a little further and just flag it as msftres with GParted?

  • Java array of arry [matrix] of an integer partition with fixed term

    - by user335209
    Hello, for my study purpose I need to build an array of array filled with the partitions of an integer with fixed term. That is given an integer, suppose 10 and given the fixed number of terms, suppose 5 I need to populate an array like this 10 0 0 0 0 9 0 0 0 1 8 0 0 0 2 7 0 0 0 3 ............ 9 0 0 1 0 8 0 0 1 1 ............. 7 0 1 1 0 6 0 1 1 1 ............ ........... 0 6 1 1 1 ............. 0 0 0 0 10 am pretty new to Java and am getting confused with all the for loops. Right now my code can do the partition of the integer but unfortunately it is not with fixed term public class Partition { private static int[] riga; private static void printPartition(int[] p, int n) { for (int i= 0; i < n; i++) System.out.print(p[i]+" "); System.out.println(); } private static void partition(int[] p, int n, int m, int i) { if (n == 0) printPartition(p, i); else for (int k= m; k > 0; k--) { p[i]= k; partition(p, n-k, n-k, i+1); } } public static void main(String[] args) { riga = new int[6]; for(int i = 0; i<riga.length; i++){ riga[i] = 0; } partition(riga, 6, 1, 0); } } the output I get it from is like this: 1 5 1 4 1 1 3 2 1 3 1 1 1 2 3 1 2 2 1 1 2 1 2 1 2 1 1 1 what i'm actually trying to understand how to proceed is to have it with a fixed terms which would be the columns of my array. So, am stuck with trying to get a way to make it less dynamic. Any help?

  • SQL SERVER – What is Incremental Statistics? – Performance improvements in SQL Server 2014 – Part 1

    - by Pinal Dave
    This is the first part of the series Incremental Statistics. Here is the index of the complete series. What is Incremental Statistics? – Performance improvements in SQL Server 2014 – Part 1 Simple Example of Incremental Statistics – Performance improvements in SQL Server 2014 – Part 2 DMV to Identify Incremental Statistics – Performance improvements in SQL Server 2014 – Part 3 Statistics are considered one of the most important aspects of SQL Server Performance Tuning. You might have often heard the phrase, with related to performance tuning. “Update Statistics before you take any other steps to tune performance”. Honestly, I have said above statement many times and many times, I have personally updated statistics before I start to do any performance tuning exercise. You may agree or disagree to the point, but there is no denial that Statistics play an extremely vital role in the performance tuning. SQL Server 2014 has a new feature called Incremental Statistics. I have been playing with this feature for quite a while and I find that very interesting. After spending some time with this feature, I decided to write about this subject over here. New in SQL Server 2014 – Incremental Statistics Well, it seems like lots of people wants to start using SQL Server 2014′s new feature of Incremetnal Statistics. However, let us understand what actually this feature does and how it can help. I will try to simplify this feature first before I start working on the demo code. Code for all versions of SQL Server Here is the code which you can execute on all versions of SQL Server and it will update the statistics of your table. The keyword which you should pay attention is WITH FULLSCAN. It will scan the entire table and build brand new statistics for you which your SQL Server Performance Tuning engine can use for better estimation of your execution plan. UPDATE STATISTICS TableName(StatisticsName) WITH FULLSCAN Who should learn about this? Why? If you are using partitions in your database, you should consider about implementing this feature. Otherwise, this feature is pretty much not applicable to you. Well, if you are using single partition and your table data is in a single place, you still have to update your statistics the same way you have been doing. If you are using multiple partitions, this may be a very useful feature for you. In most cases, users have multiple partitions because they have lots of data in their table. Each partition will have data which belongs to itself. Now it is very common that each partition are populated separately in SQL Server. Real World Example For example, if your table contains data which is related to sales, you will have plenty of entries in your table. It will be a good idea to divide the partition into multiple filegroups for example, you can divide this table into 3 semesters or 4 quarters or even 12 months. Let us assume that we have divided our table into 12 different partitions. Now for the month of January, our first partition will be populated and for the month of February our second partition will be populated. Now assume, that you have plenty of the data in your first and second partition. Now the month of March has just started and your third partition has started to populate. Due to some reason, if you want to update your statistics, what will you do? In SQL Server 2012 and earlier version You will just use the code of WITH FULLSCAN and update the entire table. That means even though you have only data in third partition you will still update the entire table. This will be VERY resource intensive process as you will be updating the statistics of the partition 1 and 2 where data has not changed at all. In SQL Server 2014 You will just update the partition of Partition 3. There is a special syntax where you can now specify which partition you want to update now. The impact of this is that it is smartly merging the new data with old statistics and update the entire statistics without doing FULLSCAN of your entire table. This has a huge impact on performance. Remember that the new feature in SQL Server 2014 does not change anything besides the capability to update a single partition. However, there is one feature which is indeed attractive. Previously, when table data were changed 20% at that time, statistics update were triggered. However, now the same threshold is applicable to a single partition. That means if your partition faces 20% data, change it will also trigger partition level statistics update which, when merged to your final statistics will give you better performance. In summary If you are not using a partition, this feature is not applicable to you. If you are using a partition, this feature can be very helpful to you. Tomorrow: We will see working code of SQL Server 2014 Incremental Statistics.

  • "0x80004005: Unspecified error" when renaming folders in Windows 7

    - by Michael Steele
    Setup I've just installed Windows 7 Ultimate 64bit. The operating system is installed on an 80GB Intel X-25M. I have a secondary 500GB Barracuda 7200.12 to be used for storage. This second drive is mounted as 'G'. Problem I'm getting an error whenever I try to rename a folder within this drive. The error says: An unexpected error is keeping you from renaming the folder. If you continue to receive this error, you can use the error code to search for help with this problem. Error 0x80004005: Unspecified error Clicking the "Try Again" button gets past the error, and correctly renames the folder. If I create a folder and leave it's name as "New Folder", then I don't see an error. I'm also able to manipulate files however I want without seeing an error. Things I've Tried Changing permissions on the drive Reformatting the drive. I've tried using both a "Basic" and "Dynamic" partition table. Checking the drive for errors using Microsoft tools Things I've Not Yet Tried When I first installed Windows I was given a choice between three types of partitions to use. I no longer remember what the choices were or what I selected. One was a GUID partition table, one was a traditional MBR, and I can't remember the third option.

  • Iomega eGo Encrypt Plus Encrypted Partition not mounting properly says "local disk"

    - by mosiac
    I'm working with an Iomega eGo 500gb Encrypt Plus portable drive. When I first set it up and installed the software and set a user password everything worked fine. The partition labeled "IomegaHDD" mounted properly and I could access the free space. Then I changed the ADMIN password which required me to lockout the device, wait 60 seconds, and then login to the Admin section and change the password, lockout the device again, wait 60 seconds, and then log back in with my user password. When I did that it of course unmounted the IomegaHDD partition to secure it, when it remounts it, it only shows up as "local disk" now and will not remount properly. I had not removed the cable while doing any of this. I have since tried unplugging and plugging back in to login to the drove but that has not worked. I'm wondering if I should remove every instance of "generic usb hub" from device manager and wait for it to re-add itself, or move it to a new set of USB ports temporarily to seee if that helps. Any ideas?

  • How to recover deleted NTFS partitions?

    - by Frank
    Last night I made a terrible mistake. I was reinstalling Windows and I accidentally deleted all the partitions on all my drives. I realized my mistake before I had created any partitions, so nothing has been written to any of the disks. I'm currently at my wits' end about what I'll do if I don't manage to recover the data. I have two 1TB drives and a 2TB. One of the 1TB was the drive I was supposed to be reformatting so nothing to be recovered there. I am currently in a Linux livecd. In this article http://support.microsoft.com/kb/245725 Microsoft advises to recreate the exact same partition but choose not to format it, and then recover the backup boot sector from the end of the ntfs volume. But none of the drives I want to recover are bootable drives. So does that mean I do not need to rewrite the boot sector? As in if I simply recreate a partition of the same size it will see all my data? Or would I be better off using the TestDisk utility? http://www.cgsecurity.org/wiki/TestDisk Please help, I'm desperate!!

  • How to prevent nginx from locking files on mounted samba partition in Centos 6

    - by Bruce Kirkpatrick
    I'm using nginx 1.3.8 inside a centos 6.3 virtualbox 4.2.4 virtual machine. The system is running the latest software available via yum update. The host OS is windows 7. The site files nginx is serving are on mounted samba partition, which is a folder on the host Windows system. I.e., inside linux, nginx paths are referring to /home/vhosts and this is mounted from D:\vhosts\ on windows. The samba partition is mounted as root with 777 privileges. /etc/fstab looks like this, but with real ip, username, password: //hostip/vhosts /home/vhosts cifs username=username,password=SECRETPASSWORD,uid=root,gid=root,file_mode=0777,dir_mode=0777,rw,_netdev 0 0 I.e. linux/nginx reads from the windows share, and not the opposite. in /etc/samba/smb.conf, I have tried to disable all samba locking features, but it seems to have no effect even after rebooting the virtual machine. locking=no share modes=no oplocks = no level2 oplocks = no kernel oplocks =no I'm receiving "Access is denied" errors in Windows or linux when attempting to overwrite the javascript file in windows that has been accessed at least once with nginx. If I run "service nginx reload", the lock is removed and I'm able to save the file. That's why I think it is nginx causing the lock. The same problem occurs with directories. However, that may be a different issue not related to the use of samba. I'm using samba so that I can manage the source code outside of the virtual machine. Also note that after I run "service nginx reload", the file I'm editing is actually automatically deleted from the windows host. SOLVED: I just reviewed my nginx.conf file. It appears the "open_file_cache" feature is what is causing the lock and deleted files. When I set this option to open_file_cache off;, My problem is resolved. I will repost as the answer when it allows me to do so.

  • locked files on HFS+ home partition shared between OSX/Linux

    - by HazyBlueDot
    I dual boot into Arch Linux and OS X 10.6 on my MacBook pro. I synced my UID between both OSes and created an HFS partition (with no journaling) to use as a shared home/Users partition. For the most part it works just as I'd expect, but sometimes when I'm booted into OS X certain files are "locked" (when I get info on a particular file the "Locked" box is checked under the "General" pane. I can resolve the issue by manually unchecking the box) and/or I get "Operation not permitted" when I try deleting or chmod'ing a file. In both cases I don't see anything out of the ordinary on the permission bits displayed with ls -l, except for a trailing '@' character in the position where the sticky bit would normally occur: -rw-r--r--@ 1 myuser mygroup 296 Mar 29 11:44 myfile This '@' character shows up on ALL normal files, so doesn't seem to be linked to the locked/operation not permission situation. On the Linux side of things I never have permission problems. To the best of my limited knowledge and experience with ACLs I've not found any ACLs on any of the files in question. For what it's worth, I do most of my file editing using emacs (Aquamacs in OSX), is it possible it is setting weird permission bits? What is the "locked" setting that OS X uses and does it have a permission bit equivalent (so at the very least I could recursively unlock all files in my home directory from the terminal) why might some, but not other files get "locked" when booting into OS X what is the meaning of the '@' character?

  • how to correctly mount fat32 partition in Ubuntu in order to preserve case

    - by Dean
    I've found there are couple of problems might be related how my FAT32 partition was mounted. I hope you can help me to solve the problem. I also included the command I used to help others when they find this post, sorry to those might feel I should use less space.

  • ubuntu - Best way of repartitioning a (running) production server

    - by egarcia
    I've got an (externally hosted) production server running Ubuntu LTS. It serves webpages (rails) and has an svn repository accesible through Apache, and a PostgreSQL db. I've got ssh access to the server and root privileges. Most of the "interesting" stuff is located in /var/ : svn repositories are inside /var/svn, web pages under /var/www, etc. Yesterday I was curious about how much disk space had it left, so I did the following: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/md1 950M 402M 500M 45% / varrun 990M 64K 990M 1% /var/run varlock 990M 0 990M 0% /var/lock udev 990M 76K 989M 1% /dev devshm 990M 0 990M 0% /dev/shm /dev/md5 4.7G 668M 4.1G 15% /usr /dev/md6 4.7G 1.4G 3.4G 29% /var /dev/md7 221G 28M 221G 1% /home none 990M 4.0K 990M 1% /tmp My 'var' partition, which holds most of the interesting part, is only 4.7G big. The /home/ partition, on the other hand, is 221G, but it is mostly unused. I should have checked the disk layout before starting installing stuff. Ideally I would need /var/ and /home/ to be "switched" - /home/ should be the one with 4.7G, and /var/ the one with 221G. Is there a way to solve this without having to reinstall the whole thing?

  • Bootable GRUB partition

    - by MA1
    I have a customized live fedora 12 USB which is working fine. What i want to do is to make a partition of my hard disk bootable so that my customized fedora can be run from hard disk. To accomplish this i did the following steps: Created a primary partition(/dev/sda2) and format it as ext3 and set it as active. Copy all the files in the live usb to /dev/sda2. Following are the live usb contents(all directories): a. boot b. EFI c. LiveOS d. syslinux Then i installed the GRUB in boot/grub Created the grub.conf in boot/grub Following are the contents of each directory in the USB: syslinux/ boot.cat isolinux.bin splash.jpg vesamenu.c32 initrd0.img ldlinux.sys syslinux.cfg vmlinuz0 LiveOS/ livecd-iso-to-disk osmin.img squashfs.img EFI/ boot/ boot.conf grub.conf boot.efi bootia32.conf bootia32.efi splash.jpg splash.xpm.gz vesamenu.c32 initrd0.img isolinux.bin isolinux.cfg vmlinuz0 boot/grub/ core GRUB files grub.conf olpc.fth Following are contents of grub.conf default=0 splashimage=/EFI/boot/splash.xpm.gz timeout 2 hiddenmenu title funLinux kernel /EFI/boot/vmlinuz0 root=live:LABEL=myFun rootfstype=auto ro liveimg quiet ssb.blacklist=1 selinux=0 vga=normal nomodeset rhgb initrd /EFI/boot/initrd0.img Now when i try to boot from the hard disk it shows the grub menu and fedora starting to load but during loading it said No root device found Boot has failed, sleeping forever So, where is the problem? what i am doing wrong?

  • GRUB reporting wrong partition type

    - by plok
    It all started when I had to replace one of the disks that the software RAID 1 on this machine currently uses. From that moment on I have not been able to boot to the Windows XP that is installed on the fourth hard drive, /dev/sdd. I am almost positive that the problem is related not to Windows but to GRUB, as if I unplug all the other hard drives so that the Windows XP disk is now /dev/sda it boots with no problem. The problem seems to be that GRUB detects a wrong partition type, which I understand suggest that something is really messed up. This is what I get when I try to follow the steps that until now had worked like a charm: grub> map (hd0) (hd3) grub> map (hd3) (hd0) grub> root (hd3,0) Filesystem type is ext2fs, partition type 0xfd 0xfd? That doesn't make sense. /dev/sdb and sdc are 0xfd (Linux raid), but not /dev/sdd: edel:~# fdisk -l [...] Disk /dev/sdd: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00048d89 Device Boot Start End Blocks Id System /dev/sdd1 * 1 30400 244187968+ 7 HPFS/NTFS edel:/boot/grub# cat device.map (hd0) /dev/sda (hd1) /dev/sdb (hd2) /dev/sdc (hd3) /dev/sdd I have been trying to work this out for hours, to no avail. Can anyone point me in the right direction?

  • How to reinstall Windows Boot Manager on EFI partition

    - by joaocandre
    So I've been trying to install Ubuntu on a second HDD on my desktop, which has W8 installed on a SSD (UEFI-only boot). Thing is, during Ubuntu installation I made the mistake of choosing to install the bootloader (GRUB) to the first disk (the SSD), and after install I could not boot into W8 (the entries in GRUB didn't work). Following these instructions, I managed to be able to get "Windows Boot Manager" back, however I lost GRUB in the process, and got a duplicate "Windows Boot Manager" entry in BIOS, along with the "Ubuntu" entry, which then I used to boot into Ubuntu. Later, I decided to reinstall Ubuntu, and formatted the HDD from within windows, however, the entries in BIOS stayed the same, and, while I had the HDD connected to the motherboard, I could not boot into an Ubuntu Live USB (in order to reinstall Ubuntu). I made another mistake by updating the BIOS, which cleared all of the EFI boot entries in BIOS, and, right now, I get an error when boot from the SSD: grub: device not found (...) So it seems that grub is still installed in the EFI partition of the SSD, and since I don't have the WBM entry in BIOS anymore, I cannot even boot into Windows, and the previous instructions don't work anymore. Is there another way to reset W8 EFI partition to the default?

  • Can't get past bootcamp Windows logo, freezes immediately after picking boot partition -- Windows 7

    - by cksubs
    Hi, I had a fine install of Windows 7 alongside Snow Leopard. I had a power outage, and Windows restarted. When I booted via the "Hold Option" sceen, it started hanging at the grayscale "Windows logo" (squares) that comes up after picking the Windows drive from the bootcamp loader (the Windows version of the grayscale Apple logo when OS X loads). I think this happened once before, and installing rEFIt helped. I did that, but it continued to hang at the same point. I finally got fed up with it and erased the Windows partition via Disk Utility. I then reinstalled Windows 7 x64 from DVD to the fresh partition. Seemed fine. Ran Windows Update then restarted. FFFFFFFFF. Hangs in the same place. What can I do? Like I said, I already have rEFIt installed. Booting the Windows 7 install CD results in the same infinite loading error. I don't have a spare Snow Leopard disk handy.

  • MySQL partition "full"?

    - by gdea73
    I have a server that runs Debian 6.2, with Apache, PHP5, and MySQL. Well, I hadn't done anything with MySQL at all so far, just Apache and PHP; I must have installed it (mysql-server) at some point along the line, and I decided to login to the database for the first time a couple days ago as I was considering using the database for a future website project. I noticed that the "root" user had a password, and I didn't recall having set one. My usual root password was incorrect. So I attempted to reset the password. sudo service mysql stop (stopped successfully) sudo /usr/bin/mysqld_safe --skip-grant-tables --skip-networking & started successfully, from what I can tell. However, mysql itself returns "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld,sock' (2)", and additionally sudo service mysql start returns "/etc/init.d/mysql: ERROR: The partition with /var/lib/mysql is too full! ... failed!" df -h tells me that / is 26% used, a 20GB partition, and /home, roughly 900GB, has only 5% usage. On a potentially related note, I've been experiencing random hangs since I noticed this problem, my tty2 randomly froze several times while idle, and the entire system is suddenly unstable. gnome-terminal also does not open. (Gnome-terminal apparently works now, disregard that part, but the server is still being somewhat unstable, I randomly lost connection when I was SSHed into it from my laptop, twice now.)

  • Recover data from a Thecus N4100 NAS jbod partition

    - by TimothyP
    I have a Thecus N4100 NAS wich had a 2TB drive in it configured as jbod partition. Later I tried adding a second drive to expand the available space. I added it to the jbod configuration but I did not get any extra space. Then I tried removing the second drive but then the NAS system indicated the jbod configuration was damaged. After a reboot it told me there is no configuration and I need to create a new RAID/jbod configuration and that I would lose all data on the drive. Of course I did not do this, I took the 2TB drive and checked with Linux if the partition was still there and it is... completely intact. I found that linux recognizes it as a /dev/mdX device and that I should be able to mount it but I don't know the file system type. Anyway.... is there a way to recover the data? Since everything has always been on a single drive it should all be there right? I can connect the drive to Windows , Linux or MacOS so whatever gets the job done.

  • Windows 7 won't boot from any bootloader except for Windows Boot Manager after partition resize

    - by user2468327
    I have a triple boot system on a single SSD: OSX, Windows 7, and Ubuntu. I use Chimera (basically another version of Chameleon) as my bootloader. Usually I can boot all 3 OSs without any issue, but after using GParted to make my Ubuntu partition 2 Gigs larger, Windows 7 throws me an error when trying to boot to it from either Chimera or Grub. The error is consistently: `0xc000000e can't find \Boot\BCD" (slightly paraphrased). However, I can still get into Windows by selecting Windows Boot Manager from the boot options in my BIOS. I've already tried several known fixes for similar issues, including bootrec /rebuildbcd (and variations), and BootRec.exe/fixMBR + BootRec.exe/fixBoot. I've also tried Chkdsk. At best this has made it so Windows 7 boots on its own by default (making me have to reinstall Chimera and change back my boot settings in the BIOS). At worst this made it so Windows won't boot period. Now I'm back full circle where I started. A detail that might be useful is that bootrec /rebuildbcd says that the number of found Windows installations is 0. I'm fairly certain that I don't have a hybrid MBR. Mainly because I have a UEFI BIOS, and with that, it appears each OS can support a GPT. So it would kind of pointless to have and deal with. I may be wrong though, I couldn't find any way of finding out for sure online. However, I know for sure that the version of Windows I have installed is the UEFI version, as well as every partition tool I've used to look at my boot drive tells me it's GPT. How do I get it back so I can boot Windows 7 through another bootloader so I don't have to manually select it in the BIOS? Preferably without a reinstall.
