You have to be just a little bit more specific than "something was missing". Did it say NTLDR was missing? If you have multiple drives, try unplugging the power cable from all but the drive you installed Vista onto. If you get the same error, then you will have to re-install Vista, but make sure that only the drive you want Vista installed to (C:\) is enabled. Windows sometimes has an issue where it installs NTLDR to an IDE drive, and the OS to a SATA drive. Unplugging the IDE drive forces Vista to install NTLDR to the SATA drive which then makes it bootable. Ok. I have two drives but only use one at a time. The other Is a back-up and I keep It powered off unless I'm doing a hard drive clone. Ill try everything again though and write down exactly what the boot manager says. Thanks.
