I've recently had a problem with my server mobo dying on me [IDE ports blew out] and having acquired another mobo found the O/S no longer boots up. It'll start and then just hang. Using the boot CD I've booted into the recovery console and used disk part, and can see that for some reason the drive letters for all the partitions aren't what they used to be. According to MS KBs I should be able to run a bunch of commands like: diskpart list volume diskpart list partition to get the volume/partition info, and then I should be able to re-assign the drive letters. But if I run these commands, I get nothing, just dumped straight back to the DOS prompt. Anyone got any ideas? All help appreciated.
