Computer won't boot the hard drive that I tell it to!

[Ingemar]

Hello gang.

Lately my computer won't start up with the device I tell it start up with and yesyesyesyesyes, I've done the boot priority thing in the BIOS and selected the Boot device I wanted in F11.

Some background info:

My primary HDD is a 250GB IDE device with Windows XP Pro (last service pack). For a while I had a 75GB (you can all stop laughing now) SATA drive with Windows 7 Ultimate, just to try it out. If I wanted to go back to my old 250GB drive with XP, it was as simple as going to BIOS, switching around the boot priority and there ya go, back to old hard drive.

I recently got a 1.5TB SATA drive, loaded Windows 7 Ultimate on it. Now, for whatever reason, whenever I load my computer it is ONLY the 75GB hard drive with Windows 7 Ultimate that ever gets loaded. No matter what boot device I put on top or anything.

Thoughts?

If you disconnect the 75GB drive, does it revert to allowing you to boot from the other ones again, or has it permanently disabled the other ones?

Have you checked the jumper pins on the new drive? Made sure it's not set as a Slave drive instead of a Boot or Master drive?

Just to be explicit, is the issue just that it won't boot from the larger drive, or that it won't see the drive at all?

SATA doesn't have master/slave.

SATA doesn't have master/slave.

O rly? I haven't had to work on a computer in a while, and I haven't messed with too many SATA drives as most of the computers I have worked on were still using PATA, so I guess I just forgot about that.
