ARGGG! Upgrading problamos muchos!

I'm upgrading my crappola VIA mobo to an ABit BD7-II. I am running W2000 on a WD 80 gig HD. For some reason W2000 won't load properly. I had this problem before and can't, for the life of me, remember what I did to fix it the first time. I'm getting this error:

***STOP: 0X0000007B (0XED41B84C, 0X0000034, 0X0000000, 0X0000000) INACCESSIBLE_BOOT_DEVICE

Sounds like a problem between the mobo and hard drive to me, but I don't know. Does anyone have any sugestions that may solve my problem?

Thanks.

You need to go to the bios. Advance Bios Option. Primary boot device. Change it to your Hard drive...Mine is HD01 (but I have a TH7-II). But it should be the same.
