rescue debian
 
Hi everyone,
I need my pc by 8 AM please help...

I asked my bro to install XP because i needed for school and he did but i cannot access debian now and i have my homework in there. I was using grub, don't have a rescue disk, don't know which hd partition it loads from. How do i figure it out and fix it?

Thanks for all the replies, i really need them

You can use your install cd to boot the box. You need to know the partition though and for this you would need at least some basic utilties on a boot disk be they either DOS or a Linux utility. You would be able to see the partitions from a DOS disk by using the command fdisk or Linux cfdisk. Once back in Debian you could then just do grub-install /dev/hdxy to get grub back. Do yourself a favour and make a floppy boot disk or cd. Have a look at this page of mine;

You can also use a Knoppix CD if you have one. When you boot a Knoppix CD, it automatically detects partions and creates corresponding directories for them in /mnt, like /mnt/hda1, /mnt/hda2, etc. From Knoppix you can open a terminal, become root with "su", them mount the partitions. For example:
Code:
mount /dev/hda2 /mnt/hda2
You can then browse the partitions to find your Debian install. You can copy files from the partition to a USB drive, or copy files to e-mail through internet mail in Knoppix. You can also chroot from Knoppix to the Debian install. For example, if Debian is on /mnt/hda2:
Code:
chroot /mnt/hda2
At that point, you are running as root on your Debian system. You can run the grub-install command from there to fix your boot loader.

Knoppix is very handy to keep around :)

I did what you said m_yates and i got my stuff from the linux partiion. Now the problem is grub-install /dev/hdc2
Code:
/sbin/grub-install: line 477: /dev/null: Permission denied
/sbin/grub-install: line 479: /dev/null: Permission denied
/sbin/grub-install: line 477: /dev/null: Permission denied
/sbin/grub-install: line 479: /dev/null: Permission denied
/sbin/grub-install: line 477: /dev/null: Permission denied
/sbin/grub-install: line 479: /dev/null: Permission denied
/sbin/grub-install: line 477: /dev/null: Permission denied
/sbin/grub-install: line 479: /dev/null: Permission denied
/sbin/grub-install: line 477: /dev/null: Permission denied
/sbin/grub-install: line 479: /dev/null: Permission denied
The file /boot/grub/stage1 not read correctly.
is what i get... /dev/hdc1 is xp

You probably want to install grub in the master boot record so that it can handle booting windows and Debian. A good overview of configuration is here: http://www.gentoo.org/doc/en/handboo...part=1&chap=10 It is for Gentoo, but the same stuff applies in Debian.

Are you sure it is /dev/hdc? That is normally the IDE slot that the CD or DVD drive is connected to.
