I recently built a new system. At the time, I did not have a retail copy of XP so I used an XP disc that came with one of my laptops to partition and get running. However, I never thought about re-installing XP when my retail copy arrived and I installed GRUB on sda1 (the windows partition).
I assume I must move GRUB to my LINUX partition before I reinstall. My thought is to install GRUB on sda2 (my root partition) and then set sda2 to be the boot partition then reinstall.
Of course I will back everything up because I can forsee something going wrong.
Thanks in advance!!!
Re: GRUB Question
You can just go ahead and re-install XP over the old XP partition, which of course will wipe out Grub.
Then a simple grub install will take over again. Or you can backup mbr using dd, then re-install mbr again using dd. Your flavor.
There are links about installing Windows after linux is installed.
