Hello all,
If I have to reinstall Window$ for some reason, and it is the primary partition on the primary HDD, I would imagine that it will overwrite the MBR. I was just wondering if the easiest way to get GRUB working again would be to:
1. Reboot using the installation disc.
2. chroot back into the installation environment.
3. Run the setup procedure for GRUB again.
Does that make sense? Are there other things about which I should know?
Thanks preemptively,
Zach

Yep, I've done that 3 times and everything went fine 
To be on the safe side, you might also want to back up your MBR:
| Code: | | dd if=/dev/hdx of=mbr.img bs=512 count=1 |

| To backup the bootloader code (without partition table) use 446 bytes. |
