i knew it was gonna happen when i was doing it and it did happen!
i wanted to compare FC3 with Scientific Linux in terms of computational performance and speed, so i tried to install both, together with winxp, on my computer. i had windows first, then FC3, leaving some hard disk space unformated for Scientific Linux. then i started installing SL and when it came to boot loader part i knew i was in trouble.
but i went ahead anyway, creating an additional line for what i thought was FC3. however, after reboot, i couldt boot in FC3 anymore.
how do i get FC3 back? how do i make it use GRUB that was installed with FC3 (i dont quite like SL's GRUB's background)?
if i try to boot FC3 it tells me:
Error 13: Invalid or unsupported executable format
