This doesn't seem to work. The way i tried was thru Control Panel > Perf. and Maintenance > Administrative tools > Computer Management.

But when trying to give the C: to the hd with windows it says 'Windows cannot modify the letter of your system volume or boot volume'

Can this be done in Safe Mode/ DOS at all?

Yes..it would seem to bugga up the booting of the PC!!!!!! GRRRRRRRRRRRR!!!!!

Tried (like the fool that i am!) to do it thru the registry (saw that MS page b4 you posted it Speedy_B) and i've just got back from a reinstallation! :(

Tip: When installing XP to a new drive..disconnect your other HDs until it is all up and running. Saves you lots of hassle if you end up with incorrect drive letters.

Thanks both for you help :)

Had that same issue when I installed the OS when I got my Raid set up. Didn't really effect anything having Windows installed on drive H, but I know what you mean when you say it bugged you. I sat through another full installation just to have it on C again!

Side note: When I pulled the other drives out and re-installed windows, it went fine. But as soon as I plugged the other drives back in, Windows gave me a message that said it couldn't boot. So, I had to change boot order in BIOS to disable all other boot options except SATA. Simply setting it to boot from SATA first didn't help. Then I was able to boot into Windows and delete all the old boot files from the other drives. Once I did that, I was able to re-enable the other boot options in BIOS. Weird.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
