BSOD, plus odd Windows error

That sounds about right. But, change the controller to AHCI before you do the install, and disconnect 1 of the wires to each hard drive except the one you want Windows installed on. And, I sure you already know to back up all your personal files to an external source before you break the raid.

No problem, that's what we're here for. I thought you meant, AHCI and not Raid, but wanted to make sure. Good luck with the install, you shouldn't have any problems.

I would make one suggestion. You don't have to do it if you don't want to. But when you boot from the install DVD, the first screen will be select your language, don't do it. Hold down the shift key and press F10. It will bring up a command window. Type diskpart into the window and press enter, in a few seconds, the window will reply diskpart. Then type list disk and press enter. The computer will show you all the disks it can see. I don't know if your SSD will show, if it does it will also show the sizes so you will know which disk is what and it will also give each disk a number on the far left. Your 500 GB disk will be listed as 465GB. Assuming it is given the number 0 (number0 not letter) type select disk 0 and press enter (or select disk 1 if that is the number assigned to it by diskpart) it will reply disk 0 is the selected disk. type ckean and press enter, the window will reply diskpart cleaned the selected disk, type create partition primary and press enter, the window will reply, diskpart created the selected partition. type active and press enter, the window will reply diskpart marked the partition active. type exit and press enter, next type exit and press enter again and you will be back at the select your language window. Continue as normal. At the install screen select (highlight) the 465 GB disk, and press install. Windows should do everything else.

This is new to me, so I am learning with you. I would go to Disk Management (right click computer, select manage, and in the left column select disk management.) In the lower half of the window, right click the second C drive, and select 'change drive letter or path,' then select change, then select any drive letter suggested by Windows, you will get a warning, ignore the warning and apply. Then reboot and see what happens. You may not be able to boot. If you cant, shut down, disconnect the drives you don't want windows installed on and begin the install. Make sure your personal files are backed up first before you do any of this.

To explain, I've never run raid 1, but you have broken the raid, however, raid 1 is mirrored raid, which means that everything on disk 0 should be an exact duplicate of disk 1. So, they would both have the same data and the same name, and by consequence, the same drive letter. I realize that is a big assumption on my part.
