Automated “ubuntu-12.04.1-server-amd64” OS installation on physical machine

- by user285336

We are using Physical server and are in process of Automated “ubuntu-12.04.1-server-amd64” OS installation on it. There are two HDD for OS installation purpose and there are RAID1 relation between them. This setup has been done through BIOS. The kickstart configuration file looks like this: #Generated by Kickstart Configurator #platform=AMD64 or Intel EM64T #System language lang en_US #Language modules to install langsupport en_US #System keyboard keyboard us #System mouse mouse #System timezone timezone Asia/Dili #Root password rootpw --iscrypted $1$Yl1QJyta$KzIT.kq3i9E5XaiQKcUJn/ #Initial user user ankit --fullname "Ankit" --iscrypted --password $1$c6Yflpea$pi1QQ59/jgywmGwBv25z3/ #Reboot after installation reboot #Use text mode install text #Install OS instead of upgrade install #Use Web installation url --url my_repo_location #System bootloader configuration bootloader --location=mbr #Clear the Master Boot Record zerombr yes #Partition clearing information clearpart --all --initlabel #Disk partitioning information part /boot --fstype ext4 --size 100 --ondisk sda part / --fstype ext4 --size 10000 --ondisk sda part /var --fstype ext4 --size 10000 --ondisk sda part swap --size 1024 --ondisk sdb #System authorization infomation auth --useshadow --enablemd5 #Network information network --bootproto=dhcp --device=eth0 #Firewall configuration firewall --enabled --trust=eth0 --http --ftp --ssh --telnet --smtp #X Window System configuration information xconfig --depth=8 --resolution=640x480 --defaultdesktop=GNOME But I am getting the below error : No root file system is defined Please suggest on this. Do we need to do any modification in kickstart configuration file. Any help in this regard will be very helpful for us. The automated Ubuntu OS installation is successful in Virtual Machine(VM) with the above ks.cfg (kickstart configuration file ) but failing in case of physical machine. Please suggest on this and if possible provide the new ks.cfg file to resolve above problem. Thanks & Regards, Rajesh Prasad

How do I align my partition table properly?

- by Jorge Castro

I am in the process of building my first RAID5 array. I've used mdadm to create the following set up: root@bondigas:~# mdadm --detail /dev/md1 /dev/md1: Version : 00.90 Creation Time : Wed Oct 20 20:00:41 2010 Raid Level : raid5 Array Size : 5860543488 (5589.05 GiB 6001.20 GB) Used Dev Size : 1953514496 (1863.02 GiB 2000.40 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 1 Persistence : Superblock is persistent Update Time : Wed Oct 20 20:13:48 2010 State : clean, degraded, recovering Active Devices : 3 Working Devices : 4 Failed Devices : 0 Spare Devices : 1 Layout : left-symmetric Chunk Size : 64K Rebuild Status : 1% complete UUID : f6dc829e:aa29b476:edd1ef19:85032322 (local to host bondigas) Events : 0.12 Number Major Minor RaidDevice State 0 8 16 0 active sync /dev/sdb 1 8 32 1 active sync /dev/sdc 2 8 48 2 active sync /dev/sdd 4 8 64 3 spare rebuilding /dev/sde While that's going I decided to format the beast with the following command: root@bondigas:~# mkfs.ext4 /dev/md1p1 mke2fs 1.41.11 (14-Mar-2010) /dev/md1p1 alignment is offset by 63488 bytes.

How to choose cell to put entity in in an uniform grid used for broad phase collision detection?

- by nathan

I'm trying to implement the broad phase of my collision detection algorithm. My game is an arcade game with lot of moving entities in an open space with relatively equivalent sizes. Regarding the above specifications, i decided to use an uniform grid for space partitioning. The problem i have right know is how to efficiently choose in which cells an entity should be added. ATM i'm doing something like this: for (int x = 0; x < gridSize; x++) { for (int y = 0; y < gridSize; y++) { GridCell cell = grid[x][y]; cell.clear(); //remove the previously added entities for (int i = 0; i < entities.size(); i++) { Entity e = entities.get(i); if (cell.isEntityOverlap(e)) { cell.add(e); } } } } The isEntityOverlap is a simple method i added my GridCell class. public boolean isEntityOverlap(Shape s) { return cellArea.intersects(s); } Where cellArea is a Rectangle. cellArea = new Rectangle(x, y, CollisionGrid.CELL_SIZE, CollisionGrid.CELL_SIZE); It works but it's damn slow. What would be a fast way to know all the cells an entity overlaps? Note: by "it works" i mean, the entities are contained in the good cells over the time after movements etc.

I can't install Ubuntu on my Dell Inspiron 15R at all

- by Kieran Rimmer

I'm attempting to install Ubuntu 12.04LTS, 64 bit onto a Dell Inspiron 15R laptop. I've shrunk down one of the windows partitions and even used gparted to format the vacant space as ext4. However, the install disk simply does not present any options when it comes to the partitioning step. What I get is a non-responsive blank table As well as the above, I've changed the BIOS settings so that USB emulation is disabled (as per Can't install on Dell Inspiron 15R), and changed the SATA Operation setting to all three possible options. Anyway, the install CD will bring up the trial version of ubuntu, and if I open terminal and type sudo fdisk -l, I get this: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xb4fd9215 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/sda2 * 81920 29044735 14481408 7 HPFS/NTFS/exFAT /dev/sda3 29044736 1005142015 488048640 7 HPFS/NTFS/exFAT /dev/sda4 1005154920 1953520064 474182572+ 83 Linux Disk /dev/sdb: 32.0 GB, 32017047552 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62533296 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb4fd923d Device Boot Start End Blocks Id System /dev/sdb1 2048 16775167 8386560 84 OS/2 hidden C: drive If I type 'sudo parted -l', I get: Model: ATA WDC WD10JPVT-75A (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 41.1MB 41.1MB primary fat16 diag 2 41.9MB 14.9GB 14.8GB primary ntfs boot 3 14.9GB 515GB 500GB primary ntfs 4 515GB 1000GB 486GB primary ext4 Model: ATA SAMSUNG SSD PM83 (scsi) Disk /dev/sdb: 32.0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 8589MB 8588MB primary Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

Installer doesn't display partition I want to install to

- by Aditya

While performing a Ubuntu 10.10 installation on my laptop, it doesn't show partitions pertaining to the PC. My PC configuration is as follows : HP Pavilion dv6 - 2020AX AMD Turion II Dual Core Mobile Processor M500 4 GB RAM OS Installed : Windows 7 500 GB Hard drive partitioned as follows : C : 227 GB (Free : 142 GB) D : 11.9 GB (Free : 1.98 GB) - Recovery F : 174 GB (Free : 18 GB) G : 50.5 GB (Free : 50.4 GB) So, I want to perform a Dual-boot installation on my PC, so that Ubuntu resides in the free disk space G:. Therefore, I started the Ubuntu 10.10 installation and select the manual partitioning feature in the installation. However, in the 'Allocate Drive Space' section of the installation, following partitions information is displayed: Partition Type Size Used /dev/sda /dev/sda1 1 MB unknown /dev/sda2 ntfs 208 MB unknown /dev/sda3 ntfs 244813 MB 168540 MB /dev/sda4 ntfs 255083 MB 3221 MB where /dev/sda - 500 GB So, what exactly is the problem? What is it should I do to install Ubuntu 10.10 in the G: disk space? Why are the partitions not being shown as the way they should be? Any Suggestions. Thank you for the help.

Having issues using fdisk and GParted with Lexar 64GB USB, but reading and writing is fine

- by MetaDark

I have recently bought a new 64GB Lexar USB with the long model name of LJDV10-64G-000-106, and I am having issues partitioning it. I am able to mount, read and write to the USB without any issues but whenever I try to partition it with GParted it doesn't show up in the dropdown. Also while using the command sudo fdisk -l I receive the error fdisk: unable to seek on /dev/sdc: Invalid argument. This is a brand new USB so I am not sure why I am having these issues, especially since the device is functioning perfectly with read/write. I have tried reformatting it on a windows machine but that does not seem to do anything. For those who want a visual my USB looks almost exactly like But 64GB rather than 8GB Edit: I have just ran GParted from the terminal and I am getting a similar error, but it may give more information on the issue. Could not determine physical sector size for /dev/sdc. Using the logical sector size (512). Invalid argument during seek for read on /dev/sdc Also clearing my USB with /dev/zero fails with the the message $ sudo dd if=/dev/zero of=/dev/sdc bs=1M dd: writing `/dev/sdc': No space left on device 1+0 records in 0+0 records out 0 bytes (0 B) copied, 0.00167254 s, 0.0 kB/s

Ubuntu 13.04 alongside Windows 8 - How to partition from Windows

- by mengelkoch

I plan to install Ubuntu 13.04 alongside Windows 8, and I'm looking for a CLEAR answer on how to conduct partitioning appropriately. I'm very new to all of this so a thorough explanation with minimal jargon would be great. I have an Acer Aspire M5 x64 with 6G RAM. I think I already figured out how to deal with the fast startup, UEFI and SecureBoot issues (I disabled fast startup and disabled Secure Boot). I am able to boot into Ubuntu from a LiveUSB, and I think I am ready to install Ubuntu. Note - despite some advice found here, I do have to disable SecureBoot to boot 13.04 from my LiveUSB. From what I have read here, it seems that I should (at least at first) create the partitions from WITHIN Windows 8, not from the LiveUSB, to avoid reported problems. I have run compmgmt.msc and I see the existing partitions. I see the following: Disk 0: 400 MB Recovery; 300 MB EFI System; Acer (C:) 444.95 GB (Boot, Page File, Crash Dump, Primary Partition); 20 GB Recovery Disk 1: 3.74 GB Primary Partition; 14.90 GB Primary Partition I gather I need to create a mounting point '/' Partition (??), a swap partition, and a home partition. Please explain what these are, how big they should be, how I create them from Windows Disk Management, and anything else I need to know. Eventually, I plan to fully replace Windows 8 with Ubuntu, but for now I want to run alongside Windows 8 and not screw things up. I don't have any critical files saved on this computer yet. Thanks.

How to improve Minecraft-esque voxel world performance?

- by SomeXnaChump

After playing Minecraft I marveled a bit at its large worlds but at the same time I found them extremely slow to navigate, even with a quad core and meaty graphics card. Now I assume Minecraft is fairly slow because: A) It's written in Java, and as most of the spatial partitioning and memory management activities happen in there, it would naturally be slower than a native C++ version. B) It doesn't partition its world very well. I could be wrong on both assumptions; however it got me thinking about the best way to manage large voxel worlds. As it is a true 3D world, where a block can exist in any part of the world, it is basically a big 3D array [x][y][z], where each block in the world has a type (i.e BlockType.Empty = 0, BlockType.Dirt = 1 etc.) Now, I am assuming to make this sort of world perform well you would need to: A) Use a tree of some variety (oct/kd/bsp) to split all the cubes out; it seems like an oct/kd would be the better option as you can just partition on a per cube level not a per triangle level. B) Use some algorithm to work out which blocks can currently be seen, as blocks closer to the user could obfuscate the blocks behind, making it pointless to render them. C) Keep the block object themselves lightweight, so it is quick to add and remove them from the trees. I guess there is no right answer to this, but I would be interested to see peoples' opinions on the subject. How would you improve performance in a large voxel-based world?

Failure to Boot Windows 7 after Ubuntu install

- by Mike

My computer is a (brand new) PC notebook, without a CD drive running Windows 7. I followed this page to install from USB: https://help.ubuntu.com/community/Installation/FromUSBStickQuick The installation went well and i am using Ubuntu now (v. 12.04 i believe) I want to be able to dual boot Ubuntu and Win7 The problem is that the disc partitioning during the Linux install caused a problem with Windows, caused some problem with windows, and windows can no longer boot when i choose it at the GNU GRUB screen. When i restart my computer i can successfully boot Linux, but not Windows 7. At the GRUB screen - if i run Win7 normally, it freezes, shows a blue screen, and returns back to GRUB - if i run Win7 recovery, i dont know how to access the files that i need in order to run windows again, so nothing helpful happens. Can you please tell me what i would need to do(or link a guide) in order to run Windows again. (Windows and Linux is preferable, but if thats impossible going back to only Windows will help too) Im guessing the easiest thing to do is just to reinstall both OS, or is there anyway to undo the partition i made during the install? Thanks

Hard time installing Ubuntu

- by Nick

I have a MSI GT780DXR that currently is booting windows 7. I've been trying to dual boot windows 7 and ubuntu for some time now. Here's specs that I think would make a difference Windows 7 500GB*2 RAID 0 hard drives. (Hardware RAID I'm not sure if it's a dedicated RAID card though) 7200RPM Nvidia GT570M Background: I tried to install 12.04 (64 bit) a few times but the Desktop live cd and pendrive boots with a black screen. I've tried wubi but it boots to a black screen as well. I then tried the alternative 12.04 (64 bit) and went through the installation all the way til partitioning. I let Ubuntu notice the raid setup and I setup my swap, /, and home drives, I used my free space to create the three partitions. I tried to resize the windows drive and it told me I couldn't and to be happy with my current setup. When I finally got past I got an error on installing GRUB 2 and decided to skip it and continued on to finish installation. When I tried to boot up I got an invalid partition table error. Windows recovery disc, and a GPARTED live cd couldn't find any hard drives. I ended up following advice and typed this into the recovery command prompt. bootrec /fixmbr bootrec /fixboot bootrec /rebuildBcd It worked and here I am now. The question is, how would I be able to dual boot windows 7 and Ubuntu 12.04 with this information? Thanks,

Install Ubuntu on Asus Eee-PC 1005PE - Dealing with special partitions

- by MestreLion

I have an Asus EeePC 1005PE netbook and im planning on doing a massive re-partitioning (going to install Ubuntu, Mint, XP, etc) Ive noticed it has 2 "special" partitions: a 10Gb Fat32 RESTORE hidden partition (used by BIOS "F9 recovery" feature) and a 16Mb "unknown" partition at the end of the drive (used by BIOS "Boot Booster" feature). So, for both partitions, my question is: Can I move/resize the recovery partition freely? What are the requirements for it? (i mean, for it still be found by BIOS when i press F9/Activate BootBooster?). Partition table order? Partition type? Flags? Label? UUID? Can i make it a Logical (instead of primary) partition? Does it must be the flagged as boot? And, more importantly: where can i find any official documentation about it? Ive ready many (mis)information about it... some say Boot Booster partition must be last (in partition table), some say Recovery must be 2nd, that it must be bootable, etc. How can I know what is really needed for the BIOS to use both F9 and Boot Booster? Note: Im using gParted from a Live USB Stick (Mint 10 / Ubuntu 10.10), and ive noticed that, since the filesystem type of the Boot Booster is not recongnized, it cant move or resize it. Can I delete it and re-create it somewhere else? Whenever i create a 0xEF partition gParted crashes and quits and i cannot open it again (must delete the partition using fdisk / cfdisk)

Installing 13.04 on an EFI partition - Share with Windows 8?

- by mengelkoch

Information I've found here suggests that for my system, I need to install 13.04 into an EFI-type partition, since it needs to boot as UEFI. I also understand it is advisable to have only ONE EFI partition on the disk; I've read here that it is OK for Ubuntu and Windows to share the same partition (please confirm). When I try to install into the existing EFI drive, I get the message "No root file system is defined. Please correct from partitioning menu." Do I change the EFI boot partition to another type? Doesn't that defeat the purpose? If I change it to Ext4 Journaling File System, I am given the opportunity to define the '/' Mount point. I haven't proceeded beyond this point for fear I am going to destroy Windows 8 by altering this partition. BTW, I created three partitions in Windows before installing, per the helpful response to my previous question. But if I try to install into the partition I created for Ubuntu, I get the "No root file system..." error again.

How do I partition my Hard drive to install Kubuntu?

- by Xdflames

I am a complete newbie to partitioning and I would like some guidance here. Can anyone explain what exactly I should be doing here? I am installing Kubuntu 12.04 on a currently Windows 7 laptop. My current Partitions say this: /dev/sda /dev/sda1 ntfs 104 MB 35 MB /dev/sda2 ntfs 319965 MB 87164 MB Basically, what I want is some guidance on what exactly to do here. All I want is a partition for my OS (Which will be Kubuntu 12.04) and a partition for all of my data. I also want to restart fresh with my hard drive, with only what I mentioned on here. I am installing Kubuntu from a flash drive (I set it up as a bootable device with Universal-USB-Installer-1.9.0.9), as I do not have any blank CDs/DVDs to burn to. What should I name my partitions? What should I set the type as? What size do they need to be? Edit: My hard drive is 320GB. Just looked it up in my BIOS. This computer will mainly be used for internet browsing and overall just messing around with the Linux OS.

Partition tool with console UI (as in server installation)?

- by lepe

Back in 2006, Ray (3DLover) posted the same question in: http://ubuntuforums.org/showthread.php?t=309680 but none of the answers were really useful. Now with a little help from AskUbuntu community, I would like to repeat his question again to see if this time it can be answered correctly. So this is the question (and what I wish too): I'm looking for a UI tool for managing partitions in a console. I have installed Ubuntu Server, so I don't have X Windows at all. fdisk and sfdisk are entirely command line. parted is slightly better, but it's not really a UI. cfdisk has somewhat of a UI, but it only works on one disk at a time, and there's no advanced options like configuring LVM or RAID. Just partitioning. I love the partition tool that is available during the OS install procedure. You can partition, configure RAID's and LMV sets. It can format the partitions with several different file systems, it can set labels, mount options and it can insert your volumes into your fstab. Is this tool available as a stand-alone program? I can't find it anywhere. I think it's called parted_server, but I can't find much information about where to get it. In the past, I have run the Ubuntu install procedure just to use the partition manager that comes with it. (canceling the install after making my partition edits) Anyone help me on this? Thanks -Ray Thanks in advance.

trying to setup multiple primary partitions on ubuntu linux

- by JohnMerlino

I currently have ubuntu desktop installed on a harddrive. I want to partition the harddrive so that I can reserve 30 gigs for ubuntu server and 30 gigs for ubuntu desktop. The drive has 300 gigs available. Right now I am booting from dvd drive and installing ubuntu server. I selected "Guided partitioning" and created a 30 gig primary partition of Ext4 journaling filesystem, set "yes, format it" for format partition and set bootable flag to on. I intend to use this 30 gig partition to hold ubuntu server and allow me to boot from it. Now I have two other partitions. They are both set to "logical", one is currently using 285.8 gigs and is using ext4 (when I try to set bootable flag to true, it gives a warning "You are trying to set the bootable flag on a logical partition. The bootable flag is only useful on the primary partitions"). More alarming it says "No existing file system was detected in this partition". Actually, Im thinking that this is the parittion that is supposed to be holding my current Ubuntu Desktop. And of course I want this to be bootable and be a primary partition, so I could dual boot from this and the server partition. Now the third partition is also set to logical and it is being used as swap area. My question is regarding that second partition. Its supposed to be a primary partition thats holding my existing ubuntu desktop edition. How do I switch it to primary and to make sure that its pointing to my existing desktop installation?

how to recover lost partitions data

- by TheJoester

I have a 2TB SATA drive that was being used as file storage on my UBUNTU computer. I was re-imaging my windows box so I used that drive to back up some files to it. I did this by taking the drive from my windows PC and putting it in my UBUNTU PC, mounted it and copied the files over. After the windows refresh I thought it would be easier to take the 2 TB drive and dock it in the external dock my Windows case has built in. Anyway it would recognize in BIOS but windows would not see it (because it was EXT3 or EXT4) so when I went into the disk manager it advised me the drive needed to be initialized. Me not thinking I initialized it as a GUID Partition table. Now it sees it as a blank drive, even in UBUNTU. I have done nothing else to write or change the drive. I was wondering if there is a qay to repair the old partitioning and get access to my files back? many thanks! EDIT: I followed the instructions in the link @kniwor sent me. I used the command sudo gpart -W /dev/sda /dev/sda and here was the result: Guessed primary partition table: Primary partition(1) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(2861671176-2861671176) chs: (1023/254/63)-(1023/254/63)d (178130/202/1)-(178130/202/1)r Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(3484550160-3484550160) chs: (1023/254/63)-(1023/254/63)d (216903/55/1)-(216903/55/1)r Primary partition(3) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Primary partition(4) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Not sure it found what I wanted. suggestions?

Will Ubuntu Live CD move MFT to resize NTFS volumes?

- by irwazr

I have a feeling some will consider this a duplicate, but please hear me out. I've been reading tons of questions and threads around this but have never really found an answer for this specifically. I want to shrink my NTFS partition to make room for a Ubuntu install, so I can dual boot them. However when shrinking the NTFS volume in Windows disk management, it will only go so far as the MFT is sitting near the end of the volume. I've read plenty of posts about why it does this, and how difficult/dangerous it is to move the MFT etc. I've also read that Perfect Disk can apparently do it under it's trial period, but I remain cautious to try this method. I was wondering however if the disk partitioning utility included in the Ubuntu install wizard handles the moving of the MFT when dragging the partition boundaries. It all seems too simple that you simply tell it the new size you want it to be. Would it tell me if it couldn't resize by the amount you requested if the MFT was an issue, or move it for you if it were able. I'm concerned it might corrupt the MFT and the volume, even though I doubt the install wizard would be so daft. So what exactly is the deal with the partition resizing tool in the Ubuntu install wizard? Will it safely resize my NTFS volume despite the location of my MFT? Thanks in advance.

Gparted can't create partition table

- by William

Here's what the problem is. About a day or so ago I used Gparted live cd to create 3 NTFS primary partitions on my external 500 gig Goflex and one extended with 2 logical partitiones. I had planned to install windows 8 on the first partition, then ubuntu and kubuntu on the other 2. After I finished partitioning my drive with gparted, I booted into windows vista to make my bootable windows 8 usb to install it with, I also decided to check to make sure all my partitions were working properly. Then I found they were, and they weren't. My 50 gig first partition I had planned to install windows on showed up normal and the 300 gigs of space left in the extended partition did as well, the rest showed up as raw. So I figured alright, something went awal while making the partitions, so I booted up gparted once again. Then to my surprise gparted showed the entire drive as unallocated, and when I refreshed the list, it showed as all the partitions I had made earlier, buy with a exclamation mark by them all. So I figured ok, might be a problem with the partition table as I'd seen a similar problem in past on a drive that was not partitioned at all, so I decided to create a new partition table and take the time out again to sit and wait. Then I got a message saying gparted could not create the partition table, followed by it showing the entire drive as formatted into ntfs. After that I figured ok I'll take a break, come back in a hour, maybe it's something I did. So a hour later I came back after having booted up windows, plugged the drive in to see if by some miracle windows could access the drive. In disk management when I plugged the drive in, it would freeze attempting to read the drive, as I'd seen in the past with raw disks, yet when I unplugged it I got a glimpse of disk management showing it as a perfectly fine ntfs file system on the drive followed by a "you must format disk K in order to use it". So I then was assured the disk was raw as that is what had happened in the past, followed by a new partition table through gparted to fix the problem and a 10 hour format in windows. So I once again booted up gparted, to get the message "error fsyncing/closing/dev/sdg:input/output error" followed by "error opening dev/sdg No such file in directory" after I refreshed and somehow saw the disk show up as perfectly fine ntfs and then tried to create a new partition table to try to wipe out all my problems and start over again. And not gparted only shows the drive there about 1/10 refreshes the rest I get the directory error. If anybody can assist me in any way shape or form I will be thankful.

New laptop, Windows 8.1, attempting dual install. Ubuntu installer doesn't 'see' existing OS

- by Flaminica

Though I've used Ubuntu for a few years, I'm new to installation. Previously I had help and now I'm doing it alone (moved across the world). Windows 8.1 came preinstalled on my new laptop (Toshiba Satellite C70-A-17C - Core i5, 8 GB RAM, 750 GB HDD). I have already followed a few steps I found online to prepare for a dual install (with Ubuntu 14.04). I backed up Windows, created a bootable Ubuntu USB and DVD (just in case one didn't work), turned off fast boot and secure boot, and shrunk C:/. The new unallocated drive portion is 292.97 GB. After shrinking C:/, I restarted Windows a couple of times to make sure everything was working fine (it is). I then attempted to install with the Ubuntu live USB. However, the Ubuntu installer doesn't see that Windows 8.1 is already installed. I don't understand, and don't want to mess with Ubuntu partitioning when I don't know where the partitions will be created. My concern is that, if I go further with the installation process, Windows might be overwritten or compromised in some way. I then tried to reboot using the Ubuntu live DVD, thinking I might get a different result. However, I can't figure out how to make the laptop boot from the CD drive. I went into the BIOS and found no option there, either. Any help is very appreciated! EDIT: Looks like I can't link directly to each photo. Here is my album of screenshots: http://imgur.com/a/zChCo Here you can see that there's no option to boot from CD drive, only USB. Everything looks okay so far. I don't understand this. Ubuntu has not yet been installed. Unmounting partitions? (I chose 'no'.) Even though the laptop came pre-installed with Windows 8.1, the Ubuntu USB installer can't see it. I chose 'something else'. I need to pick and format partitions. I scrolled down and took a second shot to include all information. Completely lost and cancelled installation.

Order hybrid mixed mysql search result in one query?

- by Fredrik

This problem is easy fixed clientside. But for performance I want to do it directly to the database. LIST a +------+-------+-------+ | name | score | cre | +------+-------+-------+ | Abe | 3 | 1 | | Zoe | 5 | 2 | | Mye | 1 | 3 | | Joe | 3 | 4 | Want to retrieve a joined hybrid result without duplications. Zoe (1st higest score) Joe (1st last submitted) Abe (2nd highest score) Mye (2nd last submitted) ... Clientside i take each search by itself and step though them. but on 100.000+ its getting awkward. To be able to use the LIMIT function would ease things up a lot! SELECT name FROM a ORDER BY score DESC, cre DESC; SELECT name FROM a ORDER BY cre DESC, score DESC;

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?

centos install / partitioning

- by ServerSideX

I'm using NOC-PS to remotely install Centos 6.2 via KVM / IPMI. I'm going to install cPanel as well and they recommend this layout /boot (99MB) swap (2x server RAM) / (remainder) In the o/s install profile within NOC-PS software, it shows as this: part /boot --fstype ext2 --size 250 part pv.01 --size 1 --grow volgroup vg pv.01 logvol / --vgname=vg --size=1 --grow --fstype ext4 --fsoptions=discard,noatime --name=root logvol /tmp --vgname=vg --size=1024 --fstype ext4 --fsoptions=discard,noatime --name=tmp logvol swap --vgname=vg --recommended --name=swap By the time the default partition setup was done installing Centos, I get this [root@server005 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-root 532G 907M 504G 1% / tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/sda1 243M 28M 202M 13% /boot /dev/mapper/vg-tmp 1008M 34M 924M 4% /tmp [root@server005 ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Fri Dec 7 18:47:24 2012 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg-root / ext4 discard,noatime 1 1 UUID=58b31aaf-5072-4fb1-a858-33bc316fa793 /boot ext2 defaults 1 2 /dev/mapper/vg-tmp /tmp ext4 discard,noatime 1 2 /dev/mapper/vg-swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 My question is, how should the NOC-PS install profile look like to get the recommended cPanel partitioning? The server has 16GB RAM, dual 600GB SAS drives and will be used for cPanel shared hosting.
