Okay, what I want to do is take a hard disk out of an older machine and put it into a new machine that I just built because the drive has apps on it that we dont have the disks for. When I put the drive in I get the infamous "inaccessable boot device" error screen (expected result but had to try). If I rewrite the boot sector on that drive with the win2000 disk (current loaded os) will the machine run the drive. Anybody have any other suggestions? Thanks guys.
