I am currently having some issue with installing Windows Vista because it wont recognize my hard drives. I was able to install about a month ago and been using it. I tried to reformat last night and it wont recognize my hard drive. The Vista install gave me "Windows is unable to find a system volume that meets its criteria for installation". I did some research and found this http://support.microsoft.com/kb/927520. Seem like i have to update my hard drive controller. It was working why wouldnt it work now???? Weird. I have a DFI LanParty nF4 SLI-DR motherboard. What should i update to update my hard drive controller? Should i update the BIOS or the nForce chipset? If the nForce chipset do i obtain it from DFI or Nvidia? Final question - does updating a chipset work like BIOS where it will be store on the hardware level or software (in OS)? Thanks for any helps.
