i was planning on upgrading a windows 7 desktop to windows 8. the first time i tried installing, it worked fine, but i first had to disconnect all drives other than the OS drive to be able to go through the installation. Then, I couldn't connect my external drive because it would be the 7th drive connected. So i remember this issue back when i was upgrading to windows 7. it had something to do with a 6 drive limit, drives larger than 2TB, uefi booting, and ahci.
So it appears i'm having this issue again. Except this time, I can't seem to be able to install windows 8 in uefi mode. I've tried all the instructions online, mainly the advice to boot from usb on a rufus created disc with fat32 and uefi options chosen. the problem is that this disc will not boot into the installer. it just hangs with a blinking cursor.
I have run out of options. I think part of the problem is the alienware motherboard I'm using, which I'm not too thrilled with. it's an obscure, off the consumer market board, and not much available in terms of online discussion or drivers or anything. I believe it's actually an MS-7543 motherboard originally made by MSI v1.0.
Anyway, I'll probably give up and just do a new computer later. Probably the server i've been planning to build for years.
