[轉貼] 讓 grub 自 Windows 奪回 MBR

當硬碟的 MBR 被愚蠢的 Windows 拿去時，執行下列動作可以把 grub 重新安裝到 MBR.

To get back our grub first stage boot, here a procedure you can use.

Boot from debian CD choosing linux2.4 kernel (default)

Change to console 2 with alt + F2 keystrokes

Make a new dir to mount the boot partition, for example /disk

mount the root partition on /disk: mount /dev/hda2 /disk (This is /dev/hda2 on my system)

Do a chroot to the root partition: issuing chroot /disk

Run grub command to enter grub shell: grub

Type in the root disk for grub, for example: root (hd0,1)

Type the following command to install grub on /dev/hda: setup (hd0)

Last step, type quit, exit from chroot, unmount all disks and reboot : quit
