My method for re-installing debian's grub-Linux Release Technology-Debian information. The following is a detailed description. Use ubuntu live cd to reinstall grub that is lost due to re-installation of xp.
1. Start the system with the live cd. Press ctrl + alt + f4 (f4 can be changed to another one) to switch to the terminal.
2. Enter sudo fdisk-l and you will see that sda7 sda8 sda9 is the debian partition, and sda8 is the swap partition.
3. Enter the following parameters:
Sudo-s-H
Sudo mkdir-p/mnt/sda6 somehow, it must be talented.
Sudo mount-t ext2/dev/sda6/mnt/sda6
Sudo mount-t proc none/mnt/sda6/proc
Sudo chroot/mnt/sda6/bin/bash
Source/etc/profile
Grub
Root (hd0, 6) Note that hd is followed by zero, not an English mother.
Setup (hd0) is zero here
4. restart the system and then go to the grub system boot. At this time, you also need to modify the following system boot Project
Title Debian GNU/Linux, kernel 2.6.8-2-386 (recovery mode)
Root (hd0, 8)
Kernel/boot/vmlinuz-2.6.8-2-386 root =/dev/sda9 ro single
Initrd/boot/initrd. img-2.6.8-2-386
Savedefault
Boot
To:
Title Debian GNU/Linux, kernel BRL. 8-2-386
Root (hd0, 6)
Kernel/boot/vmlinuz-2.6.8-2-386 root =/dev/sda7 ro
Initrd/boot/initrd. img-2.6.8-2-386
Savedefault
Boot
Title Debian GNU/Linux, kernel 2.6.8-2-386 (recovery mode)
Root (hd0, 6)
Kernel/boot/vmlinuz-2.6.8-2-386 root =/dev/sda7 ro single
Initrd/boot/initrd. img-2.6.8-2-386
Savedefault
Boot
Actually, only four numbers are changed. After the modification is completed, the system will be guided by B. During debian startup, the system stops and requires you to enter the root password or press ctrl + D. Do not enter the password and press ctrl + D to start the system.
