I have a Windows 2003 server using a single SATA drive. I need to install an Adaptec SATA raid card and two SATA drives in a RAID 1 configuration and move the whole installation over to this array. A full tape runs every night, but I'd rather not run an extra one, reinstall the OS, and restore the tape, just to move to RAID, if I don't have to.
However, I've noticed in some previous attempts to move from booting Windows from a single drive to booting from a RAID array, by just cloning the drive, that Windows will sometimes bluescreen with "missing boot device" if it cannot find the original boot device it expected.
What's the best way to do this?
