Ubuntu Installation :: O/S Grub - Unable To Mount Win Partition
Mar 22, 2010
had a dual O/S win Vista 64bit & unbuntu 9.10 64bit.
1. Had a virus on my Win vista side, anti virus could help (virus kept replicating itself - to halt all progs from running).
2. In the End Win Vista would start & was only used Unbuntu for about 2 days.
3. Tried to repair Win Vista, but noting worked.
4. Couldn't mount Win partition through unbuntu either - needed to copy some files across.
5. Eventually formatted Win partition side & re-installed Win Vista 64bit.
6. The problem now is that the grub option to select the O/S choice isn't there, thus i can't use Linux.
6b. The computer loads only Win vista 64bit (Like there usn't a Linux)
7.Checked at the disk management prog - could see my linux space but have no access.
8. Used a live Linux cd to access linux partition, just to check - it worked.
9. how can i acccess the Linux O/S as normal?

I've tried everything to solve this, been browsing the forums for the last 2 days and no solution has worked. So I got a new netbook (Samsung n150 dated 03/2011) it had ubuntu 10.10 installed but I already use ubuntu on my macbook so I'm trying out knoppix, I booted it from usb and ran the HD installer, it gets through all that and then installs grub ok, but when I reboot I get "Error 17: Cannot mount selected partition"
Things I already tried: Grub setup (grub, root (hd0,1), setup (hd0), quit) and every variation. *I tried removing the usb and setting the HDD back to first boot in the bios and then changing the menu.lst accordingly, still I get error 17. Below is the information just after boot with the usb still plugged in and set as first boot in bios.

I dualboot Ubuntu and Fedora in one hard drive. Below are the scenario.
First, installed Ubuntu 10.4 on the entire disk (40GiB of size). Then, shrink the Ubuntu installation to equal size to free up space for fedora.
Second, installed Fedora 13 using the option "Use free space on selected drives and create default layout". After the successful installation fdisk -l shows,
Code:
# fdisk -l
Disk /dev/sda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I have a 9.10 ubuntu desktop on a tower (bought 2004) working fine, and wanted to add a 10.4 server on an additional partition. After install, I stated grub may be newly written, as the list of os was fine. After reboot I got "grub rescue>" I managed to get the system working again, and now I have a grub2 menu list stating correct entries. But when I select the server entry the boot fails telling "disk not found" (The UUID of the partition given is correct, and also shown when accessing the partition from the 9.10 desktop (this needs an additional authentification when mounting) grub shell command ls does not show the partition, all other tools (life-CD, working installation, gparted etc.) do show it normally, I cannot find any difference. The partition is on the beginning of the disk

i ran into this issue only because i wanted to learn. I was reading the book, linux troubleshooting and decided to give it a try.
1) I went to /boot/ and moved vmlinuz (kernel file) to my home directory. (/root/)
2) I booted, it didnt boot (as expected) and now the troubleshooting part begins.
3) i entered to grub config mode using c
4) When i press root (hd0, (tab) it gave me 2 partitions. hd0 which is my boot partition hd1 which is my '/' partition. Please keep in mind its LVM and not a physical partition
5) If i do this, root (hd0,1), and press boot, it gives the following error Error 17: Cannot mount selected partition
During my research i found that, LVM is not supported by grub, so kindly confirm me this ? is this the reason i am not able to access my root partition ? i am doing this on vmware so no issues, but just for the sake of learning, can someone tell me some way of restoring it without using any rescure disk (livecd, liveusb etc) ?

I was dual-booting Ubuntu (10.10) and Windows 7. I installed Backtrack in addition to these 2, and the Ubuntu GRUB was replaced with the one from Backtrack.
Now when I boot, only Backtrack and Windows 7 are listed in GRUB. When I run fdisk from Backtrack, I see all partitions, and running a Partition Manager lists the Ubuntu partition as a Linux partition. However, the partition manager says that it is unable to read the contents of the partition, and that it is unable to re-read the partition table.
Also, the Ubuntu, Backtrack, and Linux Swap partition are all listed under the same Extended partition.

Still a novice in Ubuntu (Karmic Koala). I'm trying to mount an ext4 20GB partition of my hard drive so that i can use it to store data, i want it to appear on my desktop as well as on places, as far as i know this is achieved by mounting the partition in /media. At my first attempt i used the following commands. (i named the partition ondskapt)
Code:
sudo mkdir /ondskapt
sudo gedit /etc/fstab
in this document i added the following at the end:
/dev/sda4 /ondskapt ext4 defauts 0 0

I am unable to mount partition in ubuntu 10.04. Icons for different partitions are not coming within "Places". Every time I have to manually mount the partition or CD or DVD and manually unmount it. Seldom it shows the partition icons within Places>Computer. Then the partitions are getting mounted upon double clicking its partition-icon. But I fail to unmount the partition as it throws the error "media/partition_name is not in the fstab (and you are not root)."

Ubuntu has been complaining about swap not being ready during boot. The swap partition was showing up un-known in gparted. I booted off CD, reformatted it to swap. Error message gone but system monitor > resources shows my swap size to be 86GB (the exact size of my shared NTFS volume). gparted shows the swap partition as not 'swapped on' I am running Ubuntu 11.04 along side Windows 7 (as well as my factory restore partition) and an NTFS shared partition.My partition structure in order of location on disc.

sda4, extended partition

I've just bought a HP mini compaq laptop. The laptop doesn't have any CD/DVD "reader". So i was forced to download the .iso file to install ubuntu in addition to Windows XP that was present when i bought it. To do so i used UNetbootin, and i used my only hard disk as a live CD. But when i wanted to install ubuntu, they told me to create a partition. The problem is that i can't. I have only one partition sda1(nfst) which covers the whole stockage memory, and an empty space(8Mo). I can't acceed to any of the resizing or modifying options to edit the nfst partition. The only options are manage flags and umount. When i click on this one, they tell me : # umount /cdrom : cdrom is busy.

Upon trying to boot Windows I got through the GRUB startup selections and then i get stuck at a black screen displaying "Starting Up. . ." That would be no problem, I just boot ubuntu instead and mount the partition to access the programs I'm looking for. Now I get an interesting error message:
"Error mounting: mount exited with exit code 13: ntfs_mst_post_read_fixup: magic: 0x00150000 size: 4096 usa_ofs: 0 usa_count: 1040: Invalid argument Actual VCN (0x15000011d92501) of index buffer is different from expected VCN (0x1). Failed to mount '/dev/sda1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details."
I would run chkdsk in windows if I could, but that's my problem in the first place.

I have a problem with my laptop. I have Ubuntu 10.04 Lucid Lynx installed.
Everytime I start the laptop it works fine til the GNU GRUB page. There I choose code...
So what should I do? Is it something I can do myself or do I have to leave it in or something?

Is there a way I can run myProgram when desktop appears no matter if root , administrator, desktop user or an unprivileged user logs in? I actually developed a script which I set to run at startup i.e. when the Desktop appears. Script runs finely but can't mount a partition. In the script I mounted a partition using
Code:
sudo mount /dev/sda1 /mnt &> result.txt
After executing script a file named result.txt was created which contained
Code:
sudo: no tty present and no askpass program specified
In other words the mounting failed. If I run the script myself from the terminal using sudo ./myProgram i don't face this problem and the drive gets mounted successfully.

I have a 4gb SDHC card that has been partitioned with an ext2, linux swap, and fat 32 partition that I use in an Android phone. After I partitioned it this way, which I have done more than once with no problems, it quit mounting or being recognized by Android, Linux, or Windows. Windows can tell there is something there but can't mount it, Debian and Android just say it's not there. I need to try to fix the partition table which gparted told me was corrupt the last time gparted could see it.
Code:
# dmesg |grep sdb

I Am Having Problem With My JFS Partition On Which Ubuntu Is Installed. It Is Not Mounting. The Bootscreen Says There Is Serious Problem With Mounting The Partition And It Does Not Load Linux. I Tried jfs_fsck -p and -a But With No Success. I Also Tried Checking For Errors Using GParted.
The Logscreen Said logredo failed and unrecoverable error reading M from /dev/sda5/ CANNOT CONTINUE. Is There Any Way I Can Repair This Or Atleast Get My Data Back?

This is, incidentally, the same message that I see while booting. The error message goes away if I comment out the line in fstab starting with /dev/sdc.

It seemed that it would be simple enough: take the 'f' option in the expert menu of fdisk to put partitions in order after a gap had been created by a deleted partition and then make corresponding changes in /boot/grub/grub.conf because the root partition was shifted.
Well, it didn't work out that way. No matter what I try, I either see the error 15 at Stage1.5 or the error 28, which is even stranger (file does not fit into memory). All this before I even see a grub menu. It just does not get that far.
Does anyone want to take as stab at guessing what might have happened here and whether I have a chance at recovering without having to reinstall? I can provide concrete data, if anyone would be kind to give it a try. Hoping that this is a known problem and something can be guessed from what I stated here but I can be as specific as needed, just don't want to generate noise if there are no takers.

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.

I haven't been using Ubuntu for a couple of years. Yesterday I decided to fire up my ubuntu box and upgraded from 8.04 to 10.10.
The upgrade went fine, but when I boot it tells me that the /home dir cant be mounted. It allows me to Wait, Skip, or Manually mount it. If I skip I can log in and mount the partition that contains my /home folder so I know that nothing is corrupt. I'm sure my fstab just got overwritten during the upgrade, but, since its been so long, I don't recall how to (correctly) fix it back.
Cliffs:
--Upgraded from 8.04 to 10.10
--/home dir is on a separate partition & is not mounting properly
--How do I set it up so that my /home dir mounts on boot?
I'd just try messing around with fstab myself, but I really don't want to lose any data.
