Grub bootloader overwritten by WinXP bootloader, all other os' gone!
I originally had Windows Vista installed multibooted with Ubuntu.
I was using grub as provided in the Ubuntu installation. It was working fine and gave me the option to choose my linux partition, vista, or vista recovery partition everytime I booted. But today I installed XP, which I found out due to a software compatability issue I had to have! After installing XP, it overwrote? the grub bootloader. Now, when I start my computer it loads directly into XP without giving me option to boot to Vista or Ubuntu. I need major help! I have to get back to my Vista partition at the least. Is their anyway I can re-install grub? or what is the best route?
