Not necessarily a windows 7 problem, but I thought that I would try here for advice... System: evga ultra sli 790i MB intel quad core cpu 8 gb ram old hdd's = 3 500 gb (2 raid0) new hdd's = 2 kingston 64gb ssd's (striped to run os) and 4 1.5 tb seagates (raid5) I have installed Win 7 once already on the two SSDs no problem. 7 actually ran flawlessly! I left the original HDDs in it though also only after deleting the partition that the OS (vista 64bit) was on. I had to back up some files and whatnot before I installed the new HDDs. So now I have removed the 3 500s and installed the new HDDs, configured the RAID 5 setup and went to boot up and got a BOOT DISK FAILURE. INSERT SYSTEM DISK. When I insert the win 7 disk, it loads the windows files, and then before I get to the point where it asks if I want to Upgrade or Custom install, BLUE SCREEN!!! So now, I have tried my vista 64 disk so that i could get to the point where i can format my SSDs but even though i have loaded the raid drivers that came with my MB, still wont recognize my disks. So now I am stuck here.... and I am using my PS3 browser and controller to beg for help. It took a really long time to type this! Please! any suggestions would help! BTW i'm thinking that my next step is to take the SSDs to a friends PC and try to format them there. Good idea?
