I’ve been trying to install my new Sata 750GB Seagate hard drive but I’ve been running into some issues. I started to installing Vista Ultimate on it. Once it started to boot from the cd an error blue screen came up saying check the new hard ware installed. I kept on getting that message. I popped the other hard drive back in to see if the drive was bad and got the same message. Then I put the new one back in and decided to try my other Vista cd and this one installed. I have 2 hard drives installed and both are partitioned. I installed Vista on the C drive and grabbed all the Vista updates. But after grabbing all the updates I noticed that some “page files” had been installed on the D drive and I could no longer format the drive thru Vista or change the drive letter. These page files were not there after a clean install of Vista. Only after getting the updates.How and why does this happen when I’m installing everything to the C drive. Is this normal? Lastly, I shut down my computer the last 2 nites and when I started it the next day I got a screen saying Windows could not be started. I pressed enter and came to another black screen showing the name of the operating system so I hit enter and everything started up normally. I’ve gotten this start error twice after the pc was shut down overnite. But when I do a restart of shutdown and restart it starts up fine. When it’s off a few hours I seem to get that message.

Remove the drive that doesn't have vista on it. If vista fails to start, run start up repair. It's a nifty feature, and does a good job. It is located on the vista disc. It should start up now. Format or Boot nuke the other drive and replace it. All should be good to go.
