I have 4 HDDs in my PC on a Gigabyte EP45-UD3 rev1.0 motherboard on SATA ports 0-3 and running AHCI mode.
Windows 7 refuses to let me install to any partitions or disks I select saying
Setup was unable to create a new system partition or locate an existing system partition.
I will get to the bottom of this, after I sacrifice my Friday nights and weekends to Microsoft (they don't just want my money, they want my soul).
Keep tuned, if no one has the answer, I will find one. I suspect I have to rip out 3 HDDs so that the n00bs at Microsoft can actually deal with spinning media.
Really angers me how paid-for-products are so inferior to Linux they don't even qualify to be called "software".
