• I cannot format my PC

  - by Jesus Buelna

  I have a Toshiba Satellite(1) l505 6gb RAM, 6.00GB hard disk.Initially I have problem with another satellite(2) I had (mother board problem). I took my Laptop to a technician and cost a lot of money (almost as much as buying new one). So, since I have HDD problems with the first one(1) I decided to use the hard disk of the other one(2). I formatted the HDD and erased the partitions it had into 1 partition (or no partition). The problem is that when I try to format with the SO CD, in the screen, where I have to decide in which partition I want to install the SO, the only one option I have says "unallocated partition and I receive this message "Windows cannot install the SO in this partition, run files do not existed or maybe corrupted" When I erased the disk with Parted Magic, Did I erased any files needed for running the installing disk? I don't know. Is it possible to fixed or reinstate the disk to install the OS? By the way, I checked the disk physical health with Parted Magic, and it is OK. One more thing when I erased the disc to 0, I used the safety option offered by the Parted Magic.Need help please.

• Fixing partitions and Installing BackTrack

  - by Josh

  My whole problem started when I started trying to install Backtrack(3 or 4) Backtrack was trying to install itself over my entire windows partition (Which I had combined into one when I installed windows 7). So I booted back into windows 7 on my netbook (eee pc 1000 HE btw) I went into disk-manager with the aim of making a partition to install backtrack on but came out with a really screwed up drive. So I had two partions when I started: the windows system partition, and then my main partition and they were blue in diskmanager (I think that has something to do with formatting). After I went through the steps to make a 10 GB FAT32 partition for backtrack I had about five partitons one called PE: that I have no Idea what it is the windows system file, my main partiton 10 GB unallocated space, and two other partions under 50MB each that are both unused space. And they were all converted to simple volumes (Green instead of blue). And backtrack still wants to erase my entire drive. Question number 1: How do I get it back to the way it was? Question 2: How to I get backtrack to dual boot on my netbook?

• Installing ubuntu 12.04, installs but does not boot after it asks me to remove the CD

  - by Randnum

  I'm Trying to install Ubuntu 12.04 on my computer. It had an old copy of Windows 7 on it I tried to reformat the hard drive for a fresh install of Ubuntu but I think I messed up the partitions in some way that prevents it from fully loading. I'm able to complete the install fine and use guided partitioning so it should be happy but when it gets about 90% through at the part that ejects the cd and restarts the system it fails. After ejecting the CD and restarting it just loads up the bios lenovo splash screen then purple then black. I can hear a sound from my speakers like some notification sound but there is no text on my screen. I've since gone back in under Rescue System to try and reconfigure the partitions hoping that it will fix it and i've tried several combinations. Currently it's SCST1 (0,0,0) (sda) - 500.1 GB ATA WDC WD5000AAkKX-0 #1 100.0 MB K biosgrub #2 494.1 GB B K ext4 / #3 5.9 GB F swap swap 8.2 kb FREE SPACE I'm not sure if I need to set the ext4 to contain the boot flag but if I don't include at least one partition with the boot flag enabled it complains saying that "The partition table format in use on your disks normally requires you to create a separate partition for boot loader code. This partitionshould be marked for use as an "EFI boot Partition" and should be at least 35 MB in size. Note that this is not hte same as a partition mounted on /boot" Like I said it seems to have installed all of the actual data from the CD it's just not properly booting for some reason

• my multi boot can't boot to XP 'resumeobject' is missing

  - by GwenKillerby

  In my multi boot set up, booting to vista and 7 goes fine, but when I try to boot to XP, i get an error Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart your computer. 2. Choose your language settings, and then click "Next." 3. Click "Repair your computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \NTLDR Status: 0xc000000e Info: The selected entry could not be loaded because the application is missing or corrupt. See below. Clearly the resumeobject seems to be missing in the XP entry ("Real Mode Boot sector"), only I don't know how to restore it. Vista is on **C:**, Win7 is on **F:** (as is the bootmgr ??? ) and WinXP is on **E:** What I've tried: [1] I've used about 5 windows discs, that is the Recovery Consoles from real XP install CD's and 3 virtual Recovery Consoles. All failed. The real CD's work ONE time, but won't let me finish, I only got as far as [b]fixboot E:[/b] Then they shut the laptop down, I kid you not. On a next startup, all 5 CD's ask me for some Admin password that I've never added! [2] I have VisualBCD and EasyBCD, but the most obvious things I tried there didn't solve the problem. So know I don't exactly know what to do with them. [3] I CAN boot into XP with the FIX NTLDR workaround of http://milescomer.com/tinyempire.com/notes/ntldrismissing.htm, but it doesn't fix it permanently QUESTION: How do I fix it permanently? bcdedit /enum output: Windows Boot Manager -------------------- identifier {bootmgr} device partition=F: path \bootmgr description Windows Boot Manager locale en-US default {current} displayorder {current} {812e27a9-27b7-11e4-8fb4-dfa8174ae8dc} {812e27ac-27b7-11e4-8fb4-dfa8174ae8dc} timeout 30 resume No Windows Boot Loader ------------------- identifier {current} device partition=C: path \Windows\system32\winload.exe description Vista locale nl-NL osdevice partition=C: systemroot \Windows resumeobject {73d8b5bc-2764-11e4-b181-806e6f6e6963} Windows Boot Loader ------------------- identifier {812e27a9-27b7-11e4-8fb4-dfa8174ae8dc} device partition=F: path \Windows\system32\winload.exe description Daisy Etta locale en-US osdevice partition=F: systemroot \Windows resumeobject {b8c234a4-27b0-11e4-b8b3-806e6f6e6963} Real-mode Boot Sector --------------------- identifier {812e27ac-27b7-11e4-8fb4-dfa8174ae8dc} device partition=E: path \NTLDR description XP Thank you.

• Linux: Force fsck of a read-only mounted filesystem?

  - by Timothy Miller

  I'm developing for a headless embedded appliance, running CentOS 6.2. The user can connect a keyboard, but not a monitor, and a serial console would require opening the case, something we don't want the user to have to do. This all pretty much obviates the possibility of using a recovery USB drive to boot from, unless all it does is blindly reimage the harddrive. I would like to provide some recovery facilities, and I have written a tool that comes up on /dev/tty1 in place of getty to provide these functions. One such function is fsck. I have found out how to remount the root and other file systems read-only. Now that they are read-only, it should be safe to fsck them and then reboot. Unfortunately, fsck complains to me that the filesystems are mounted and refuses to do anything. How can I force fsck to run on a read-only mounted partition? Based on my research, this is going to have to be something obscure. "-f" just means to force repair of a clean (but unmounted) partition. I need to repair a clean or unclean mounted partition. From what I read, this is something "only experts" should do, but no one has bothered to explain how the experts do it. I'm hoping someone can reveal this to me. BTW, I've noticed that e2fsck 1.42.4 on Gentoo will let you fsck a mounted partition, even mounted read-write, but it seems only to do so if fsck is run from a terminal, so it can ask the user if they're sure they want to do something so dangerous. I'm not sure if the CentOS version does the same thing, but it appears that fsck CAN repair a mounted partition, but it flatly refuses to when not run from a terminal. One last-resort option is for me to compile my own hacked fsck. But I'm afraid I'll mess it up in some unexpected way. Thanks! Note: Originally posted here.

• Is it possible to mount a disk image, created with dd, to a directory on a mounted external usb hdd?

  - by Keeper Hood

  I have an image of my home (/dev/sda3) partition, which I've created using the "dd" command. dd if=/dev/sda3 of=/path/to/disk.img I've deleted the home partition via gparted in order to enlarge my /dev/root partition. Then I've recreated the /dev/sda3 partition which is smaller in size then the one I've backed up to the image. I was wondering since I have a 2TB external HDD, could it be possible to mount my backed up image on the external HDD and then copy the files into the /home directory. Since the external HDD would be already in a "mounted state", I'm unsure whether this is a good idea, mounting on a mounted device. I'm running Slackware 13.37 (64bit). used ext4 on all the partitions. resized the root partition with gparted live cd. I've tried mount -t ext4 /path/to/disk.img /mng/image -o loop It gave me an fs error (wrong fs type, bad option, bad superblock on dev/loop/0) Then i did dmesg | tail which outputs: EXT4-fs (loop0) : bad geometry: block count 29009610 exceeds size of defice (1679229 blocks) I have no idea what to do, I want to restore my /home data from the image I've backed up.

• Unable to boot directly to Mac OS X

  - by Prashant

  I was trying to install Windows 7 on my Macbook pro using bootcamp, after creating partition I found out that I missed my DVD at office desk. Later I deleted the partition, but when I restart the macbook it kept telling that "No bootable device found" even after deleting the partition, I'm expecting it to boot directly to Mac OSX. Is there any solution to fix this problem?

• Moving Windows XP from ICH10R RAID 5 to single disk using Linux [migrated]

  - by tudor

  A friend's machine running Windows XP refused to boot recently which is running 3 SATA disks on RAID 5 (which was previously upgraded from RAID 1 not by me). I have determined there to be a disk failure. The disks have been replaced many times in the past few years. I wish to backup the RAID5 partition before I try anything to fix it. The RAID chipset used is ICH10R/DO. So, I plugged in an extra IDE drive and an Ubuntu USB key and looked at the RAID. The partitioning is a mess, but I did find at least one degraded but working RAID array with two partitions, one 79GB and the other 86GB. Then I: 1) Partitioned my IDE disk using fdisk to have a partition of 80GB and bootable, and marked as NTFS. 2) dd the contents of the array to the partition 3) disconnected everything else 4) inserted a Windows XP CD and ran fixboot, fixmbr, and bootcfg. They all run ok and claim that they worked. (e.g. bootcfg detects the Windows partition, fixboot returns saying that it was written correctly.) However, I'm still getting an error like "DISK FAILURE, BOOT DISK NOT FOUND". I have tried running the GRUB rescue disk, which also runs ok, but won't boot into Windows. It just stops with a flashing cursor after chainloader +1, boot. One clue may be that the partitions appear to be wack. One disk has a 79GB RAID partition on a 500GB drive with a offset, the second disk has a 320GB RAID partition across the whole drive. Additionally, the BIOS lists the RAID size as being 149GB. I don't see how this works. How are they even assembling the array when the partitions are so different? I have also tried running the Windows XP automated repair tool, but that didn't work either. I'm presuming this is something simple. Perhaps Windows is attempting to boot into RAID and, upon not finding it, simply crashing? Perhaps the 79GB partitions offset means that it's looking into the disk by that much? Please help!! To clarify: I want to make the single IDE disk bootable with a copy of the array so that I can prove/disprove that it's just that Windows has become corrupted, and use windows tools to correct it before attempting the same thing on the RAID array. That way I have a working backup and can show the process I used to fix it.

• Missing autochk program during boot

  - by a sandwhich

  I just resized a windows partition which involved shifting about 160GB to the left. After that it couldn't find the boot like normal so I ran the system repair tool like normal(I resize this partition a lot and each time I have to use the repair disk). But, this time, when I rebooted into the recovered 7 partition, it displayed the windows logo like normal but then flashed up autochk program not found -- skipping autocheck After that being on the screen for about 8 seconds, there was a flash of a bluescreen with white text and it rebooted. I have tried running the repair disk multiple times, but it returns and fixes the same problem each time, and the same thing happens on boot each time. Is there anything I can do to fix this short of reinstalling Windows? I have also ran two chkdsks from my vista partition with no errors reported and when viewing all the files on the drive everything seems to be in place.

• My Western Digital 500GB Passport disk says "not formatted" when I plug it in Windows

  - by learnerforever

  Hi, When I plug my Western Digital 500 GB Passport disk in my Windows machine, it says "not formatted, do you want to format it" something. I started having this problem after I put it in an old desktop at home. I don't exactly know what went wrong. May be partition table is corrupted etc. Questions: Some quick search on internet tells me there are partition fixing utilities, which can fix corrupted partition table. testdisk being one of such utiities. I can understand how to use this to copy files from the disk to some other location, but I would like to fix the partition table in-place so that I don't have to temporary move around my data of approx size 300GB, then format passport disk and then again bring back the data. Is there any way I can fix the partition table in-place? Also, how to know which file system was there originally in the disk? Can I only keep the same file system? My current laptop is running Windows 7. Earlier I used to use Windows Vista. My other laptop has Windows XP. So I have access to Windows 7 and Windows XP. Please help! Thanks,

• Add MS-DOS boot option to Windows 2000

  - by Ben Miller

  I've got an old laptop that is running Windows 2000 & Windows 98 in a multi-boot configuration. I need to add MS-DOS to that list of startup options. I've already added a primary partition, formatted it for FAT16 and made it bootable, and installed MS-DOS 6.22. My question is, how do I add my MS-DOS partition to the list of startup options? More information: My single hard drive has three primary partitions: 0: FAT32 Windows 2000 1: FAT32 Windows 98 2: FAT(16) MS-DOS 6.22 Currently, the boot-up screen lists Windows 2000 and Windows 98 as options, with Windows 2000 as the default choice. My boot.ini file currently looks like this: [Boot Loader] Timeout=30 Default=multi(0)disk(0)rdisk(0)partition(1)\WINNT [Operating Systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect C:\="Microsoft Windows 98"

• Not able to access a folder in Windows 7 and not able to see in Ubuntu.

  - by Rohit

  I have four partitions on my hard disk. Partition C has Windows XP installed and Partition G has Windows 7 installed. Ubuntu 10.10 is also installed, probably in F. Partitions C and G are NTFS. When I boot into C, XP is loading but when I click on the C Drive in MyComputer, it displays: "Access is denied". Windows 7 displays the folder tree of C, but when I try to open a folder, I am not able to view the contents. The same error: of Access Denied. When I try to view the C Partition using Ubuntu, the entire C partition is not visible. I tried following commands to take ownership of the C drive: takeown /f C: cacls C: /G Rohit:F but still I am not able to get rid of "Access Denied". I again tried the above commands from the Windows 7 safe mode, but still the problem persists. The two commands return "Successful", but nothing is happening.

• Only three primary partitions?

  - by ctype.h

  As everyone probably knows, Windows allows a drive to have four primary partitions, one of which may be active. However, I have only three primary partitions. I shrunk one and created a fourth partition so I could install Windows 8 on it, but Disk Management only allows it to be a logical partition. Why might this be the case? If I cannot convert it to a primary partition, is it advisable to install Windows on a logical partition? If so, is hibernation supported?

• Debian software raid 1: boot from both disk

  - by bsreekanth

  I newly installed debian squeeze with software raid.The way I did was, as also given in this thread. I have 2 HDD with 500 GB each. For each of them, I created 3 partitions (/boot, / and swap) I selected the hard drive and created a new partition table I created a new partition that was 1GB. I then specified to use the partition as a Physical Volume for RAID. and used for /boot and enabled bootable. Created another partition, which is of 480 GB, and then specified to use the partition as a Physical Volume for RAID. and used for /. Created another partion and used for swap Then RAID configuration: Through Configure RAID menu - create MD device - (2 for the number of drives, 0 for spare devices) Next select the partitions you want to be members of /dev/MD0. I selected /dev/sda1 and /dev/sdb1 (for /boot) Next select the partitions you want to be members of /dev/MD1. I selected /dev/sda6 and /dev/sdb6 (for /) And no RAID for swap partitions 'Finish Partitioning and write changes to disk' -- Finish the rest of the install like normal Everything is ok now, except I am not sure how to test my raid config. When I pull the power of the HDD, it only boots from one disk. I read in some forum that I may have to install GRUB manually on the other. In Debian Squeeze, there is no grub command. Not sure how to make my software raid bootable from both disk. Also, please comment on my steps above. Anything unusual. I configured /boot partitions of both disks to be boot=yes. Not sure whether that is ok. Thanks, Bsr

• Macbook Pro won't boot from DVD with SSD

  - by Adam Carr

  Here's the timeline of events. Had a running MBP 17 Early 2011 Thunderbolt with OWC Mercury Extreme Pro SSD 115GB drive. Installed Windows 7 via bootcamp. I have done this multiple times before and every time I need to format the bootcamp partition before installing. I think this time I actually deleted the partition and then selected the freespace to install. This worked fine for the most part but I wasn't able to boot the boot camp partition using vmware fusion. I gave up and used the boot camp assistant to revert back to one mac partition. I was getting some odd behavior so I rebooted the machine. It then came up with a message saying no bootable partiton. This made me think (and still does) that the windows install using the free space versus the boot camp partition caused the windows MBR boot loader to get installed incorrectly and mucked up the OS X installation. Ok, fine, I can just reinstall. I can't seem to boot from the original MBP installation DVD. I hold down c on boot but I never get past the all grey screen. I hear the DVD drive spin up but it eventually stops. I put the original HD back in it and everything works fine but when I put the SSD in, I can't boot from the DVD drive. I have already set up an RMA with OWC to send back the drive but considering the order of events, I feel as though it isn't a hardware issue but can't seem to figure out how to fix it. I can always send it back in but figured I would check and see if anyone could offer some guideance/assistence before doing so.

The problem is that I am on a rackspace cloud server and I need a second partition on both the primary and secondary servers that I will replicate with DRBD. Rackspace does not allow me to create a second partition. I am left with the default single partition. How can I mirror using DRBD?

• Mac OS X: All bootcamp options start Windows

  - by Brian Heylin

  I just installed the latest security update on Mac OS X (installed on 2-10-2010). On restart my Mac booted in Windows 7, which I had installed previously and was set not to boot by default. I tried to restart holding the alt key, and selected the Mac OS X partition, but still the Windows 7 partition boots. It does not matter what partition I choose, Windows 7 always boots. I took a look in the OS X partition and noticed that the admin home folder is empty, or at least Windows is not showing any files there. There is another user on OS X and I can see their files no problem. This has me stumped, has anyone any suggestions for a finding a solution?

• 3 TB HDD won't reactivate

  - by isif

  After doing a clean install of Windows 8 my Seagate 3 TB HDD won't reactivate in Disk Management. The two volumes are there but I can't use them for some reason. The drive was previously used with a GPT partition table, I can see the two spanned volumes but can't reactivate either. I backed up all my files from Windows 7 onto that drive and desperately need them back. What can and should I do to get the drive back up and running? When I go to Disk → Properties → Volumes, it claims the drive has a MBR partition style, so converting to GPT somehow without data loss should work. gDisk claims to be able to do that but when I point it to the drive, it claims that it has a GPT partition and a protected MBR partition. Any suggestions on what to do?

• BootMgr is missing, usual fixes don't work

  - by parsley72

  I know this question has been asked before but I've tried all the usual fixes and nothing works. Basically the hard drive had two partitions with Vista and Windows 7. I've deleted the Vista partition to make more room and expanded the Windows 7 partition to fill the drive (using GParted). I've tried: Running Startup Repair - it doesn't find any problems. Setting partition to Active - worked. bootsect /nt60 c: - worked. BootRec /FixMbr - worked. BootRec /FixBoot - worked. BootRec /ScanOs - I get the message "Total identified Windows installations: 0" BootRec /RebuildBcd - I get the message "Total identified Windows installations: 0" BcdEdit shows a Windows Boot Manager and a Windows Boot Loader, both on C: partition. What else can I try?
