if you have this problem.....

Hey guys... i finaly got my system built!

780i
4 gig
vista ultimate 64 bit
8600 gt<~~~~ hahaha
OCZ 750 watt gamer extream
cool mater 690 tower
250 gig and 500 gig Hd's

Anyways..... i was a major issue having vista install with both HD's hooked up. So after 3 hours of trying different things i was looking threw bois and saw that it was putting both the 250 and 500 as master even after i had them set up as 250 master/ 500 slave. still i would get a message that said " windows is unable to find a system voulme that meets its criteria for installation " Well if any of you get to the part where this message happens you will notice it is detecting all your HD's ( 2 in my case ) windows trys to load them on both! ( as a raid config? ) so if you disconect the HD you are useing as a slave ( after powering down ) and reboot with the vista disk in the cd/dvd drive go threw the long prosses of entering your key code. you will notice that it now only see's 1 HD. now hit enter after selecting the HD you want to instill vista on. This should work, it did in my case!
I hope this helps someone else. i wish i found something like this on this forum when i was having this problem. so here i am posting what i found to fix it. Good luck guys and gals

they are sata HD's both are seagate barracuda's the 250 is the 7200.10 and the 500 is the new 7200.11 The only jumper i saw on the back was just for the 1.5 or 3 gig interface? I am useing the fxf navidia 780i SLI I have my dvd/cd burner/drive hooked into the IDE connector.

thanks Arkadi! i gave up last night after they both where being shown as master in a raid config. i had raid disabled. i also have to go back and change the start up option. i still have it booting from the cd/dvd rom. im going to play with it alittle more today
