Ntfs partition lost after reinstall grub
Hi all,
I have an Athlon 64 3700+\Nvidia Geforce FX5500 + Ubuntu Edgy Eft. I have dual booted well both Linux and Windows XP until yesterday. The prob arose as I installed gfxboot to have a Suse-like Grub. I have not had the good idea to take a backup of my mbr by using the dd command. :( I hope it is possible to recover my XP partition with your suggestions. I can give you some information about my o.s.. ---------------------------------------------------------CURRENT PARTITIONS ---------------------------------------- armonica@persik-desktop:~$ sudo fdisk -l Password: Disk /dev/sda: 200.0 GB, 200049647616 bytes 255 heads, 63 sectors/track, 24321 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 9249 74292561 7 HPFS/NTFS # I can't have any access to it.

According to your fdisk -l listing, it doesn't look like the partition structure is whacked. If you have ntfsprogs installed, you could check it out with
ntfsinfo -m /dev/sda1 There is an ntfsfix program which might be able to fix it enough for the windows program to check the partition and repair it. You can also try the "errors=continue" option instead of "errors=recover". ( These two options are listed in the kernel's ntfs.txt file, but not in the mount manpage.) |
Hi,
this is the output of ntfsinfo: armonica@persik-desktop:~$ ntfsinfo -m /dev/sda1 Unknown option '/dev/sda1'. You must specify exactly one device. Usage: ntfsinfo [options] -d dev -d dev --device dev The ntfs volume to display information about -i num --inode num Display information about this inode -F file --file file Display information about this file (absolute path) -m --mft Dump information about the volume -t --notime Don't report timestamps -f --force Use less caution -q --quiet Less output -v --verbose More output -V --version Display version information -h --help Display this help Developers' email address: linux-ntfs-dev@lists.sourceforge.net Linux NTFS homepage: http://linux-ntfs.sourceforge.net ---------------------------------------------------------------- At the time the utility doesn't recognize my hard drive or at least, it finds a linux partition and a hard drive but it can't find the first partition of the only hd (sda1) the ntfs one. Other suggestions? unconcrete |
Partition structure isn't showing sda3 and there is a hole in the partition structure evident from fdisk. However fstab is showing sda3. Also fstab has two entries for sda5. Not sure what happens here.
You might try commenting out the fstab entry for sda1 and replacing it with a line like this: Code:
/dev/sda1 /media/pippo ntfs user,umask=0,noauto,exec,iocharset=is |
Does the new Grub start Linux?
Good news. The new Suse-Grub would not have altered your partions at all so your data is still there...safe and sound. You just have to find it. Is the new Suse-Grub working?...Can you boot into Linux? If so then please post your /boot/grub/menu.lst file? You may just need to identify your Windows OS in this file if it was over written when you installed the new Grub.

A Link...
Here is a link from someone with a similar problem. Near the bottom there are several good sugesstions.
https://bugs.launchpad.net/ubuntu/+s...rub/+bug/21175 When you install grub in the first sector of Windows partition, ex. /dev/sda1 or /dev/hda1, you will get an error 17, which means grub does not recognize the NTFS (Windows) file system. These are the errors I see above. Grub should be installed in /dev/sda and not sda1. please post your boot/grub/menu.lst file. If your menu.lst file is correct and Grub wasn't loaded in /dev/sda1 by mistake then I would rebuild my master boot record by running the fixmbr command followed by the fixboot command. This will kill GRUB and boot you into Windows using the Windows default bootloader. Jay |
I would do two things
(1) I would try to boot it manually. Under the normal circumstance in Ubuntu's Grub screen pressing the "c" key will drop the user into a Grub shell. If this is the case XP will fire up if it is any good by commands Code:
root (hd0,0)(2) I would mount the partition manually and check if I could access it by another Linux. This can be done in an installed Linux or just from a Live CD. In root terminal Code:
mkdir /mnt/sda1 |
You need to run ntfsinfo as root so it has rights to read the device.
Skipping to /dev/hda4 is normal. That means it is the extended partition. "There can be only one." |
Quote:
There can be only one extended partition but it does not have to be the last one in the partition table. It can be any of them, and you can have one or more normal physical partitions after it if you wish. And if you read the output of the fdisk, you will see that the cylinder boundaries clearly show a hole in the partition table, with a big gap between the end of sda2 and the beginning of sda4. You need to be certain of your facts before pronouncing them. |
Grub can't find ntfs

Beats me?
Wow, that menu.list has the most commented lines I have ever seen! It makes for a long and confusing read. My menu.lst is no longer than this response. I have been informed that GRUB will give error 17 and not run at all if loaded in sda1 so this may not be the case, sorry. I didn't see anything obvious but before I close that file I would try two simple things, just for shits and giggles. Neither of these suggestions follows any logic so don't laugh when you read them but I am out of logical ideas. I wish I could have been of more help. I hope you find a solution.
1. Just above your Windows XP entry, GRUB placed these two lines: title Other operating systems: root Comment them both out with #. reboot and select Windows XP. I don't see a need for them and the keyword root...followed by no root??? Very odd. This entry should not affect the Windows XP entry below it but I would clean it up anyway. Reboot and try XP again before doing #2. 2. Change (hd0,0) to read (hd0,1)as shown below. hd0,0 should be correct so if it doesn't work then change it back. This shouldn't work but I googled another thread that stated this DID work for another person...then again I could find just about anything online if I looked long enough. I am curious to see if it works. Good luck. title Microsoft Windows XP Professional root (hd0,1) savedefault makeactive chainloader +1 |
