I installed a new 500GB drive and moved my 320GB to be my second drive. I'm installing Fedora 7 64 bit. Everything was working fine until I installed the new 500GB drive. Both are SATA drives. The install looks like it works okay, but will not boot. The last thing on the screen is "GRUB" and no grub boot screen appears. I have tried this three times with the same result. Maybe I have a bad drive or did something wrong installing the drive or have a configuration problem. The last time I installed with all the defaults. I used the recovery option and /boot does have files in it.
Does anything have any idea how to debug this problem?
