Problem with bootloader

debpu06 · 09-21-2008, 01:35 PM

Okay, so I had a Mandriva 2007 and windows xp on separate partitions and when I was resizing a third small partition that was on my harddrive through xp I accidentally deleted Mandriva. When I tried to reboot my computer it said GRUB error 22. I can no longer access my xp and I was wondering if there was any way to fix the problem through a linux distribution that I can put on a pendrive cause I don't hava access to a cd burner and I don't have the original xp cds.
Thank you in advance

Can you give us the output of:

# /sbin/fdisk -l

and

# less /boot/grub/menu.lst

[fedora@localhost ~]$ /sbin/fdisk -l
[fedora@localhost ~]$ less/boot/grub/menu.lst
bash: less/boot/grub/menu.lst: No such file or directory
[fedora@localhost ~]$

I am using my friends fedora pendrive on my comp

# - means that you need to do it as root, so:

Code:

$ su

write your root password, and then:

Code:

# /sbin/fdisk -l

There is a white space after less

Code:

less /boot/grub/menu.lst

Sorry, I just realised that you are using linux from a pendrive.
Try supergrub http://www.supergrubdisk.org/
There's a download for usb as well. It should restore your master boot record.
