I installed an OCZ SSD last night, and had a hell of a time getting my operating system partition onto the new drive. I ended up using some recommended migration tool, but despite my best efforts the new drive wouldn't boot (black screen with "Failure to boot" or what have you). I used the windows 7 upgrade DVD to repair the install, and after that it booted perfectly several times.
Today, I tried to boot the system only to get another failure to boot screen. I figured that the issue was probably the bios trying to boot from the old drive rather than the SSD, but this wasn't the case. I decided to pop in the repair disk again, hoping that I could once again cajole it into working. Unfortunately, now the upgrade DVD won't even load! I've been staring at the "Starting Windows" screen for fifteen minutes now to no avail.
I also tried to use the sysrescue cd in hopes of just formatting the SSD with GParted and reinstalling from the Windows DVD. Unfortunately, this disk also had problems. It seemed to hang for several minutes at the "Searching for SATA_something or other" portion, but finally worked. When I loaded GParted, it couldn't even see my SSD! The Bios is still seeing it fine, but GParted won't, and I can't boot the Windows DVD. What in the hell is going on here!?
Note: After at least ten minutes the Windows DVD has booted at least so far as to give me a cursor. This is good, but I still can't fathom why a hard drive problem would cause my DVD drive to work at 1/10th its normal speed.
