Ive just installed my Raptor as my boot drive. During its setup, I unplugged the other two drives. Once windows was installed, I plugged the other drives back in. But now the boot drive is M:\, the Files drive is C:\ and the programs drive is D:\ :( How do I get it so that windows is on C:\, Programs on D:\ and files on E:\? I know I can shuffle drives around in disc management, but I can move the boot drive.
 
I don't know if this will be any help to you..


To change or swap drive letters on volumes that cannot otherwise be changed using the Disk Management snap-in, use the following steps.
NOTE: In these steps, drive D refers to the (wrong) drive letter assigned to a volume, and drive C refers to the (new) drive letter you want to change to, or to assign to the volume.
This procedure swaps drive letters for drives C and D. If you do not need to swap drive letters, simply name the \DosDevice\letter: value to any new drive letter not in use.

Changing the System/Boot Drive Letter
Make a full system backup of the computer and system state.
Log on as an Administrator.
Start Regedt32.exe.
Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

Click MountedDevices.
On the Security menu, click Permissions.
Check to make sure Administrators have full control. Change this back when you are finished with these steps.
Quit Regedt32.exe, and then start Regedit.exe.
Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
Right-click \DosDevices\C:, and then click Rename.

NOTE: You must use Regedit instead of Regedt32 to rename this registry key.
Rename it to an unused drive letter "\DosDevices\Z:". (This will free up drive letter C: to be used later.)
Find the drive letter you want changed. Look for "\DosDevices\D:".
Right-click \DosDevices\D:, and then click Rename.
Rename it to the appropriate (new) drive letter "\DosDevices\C:".
Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".
Quit Regedit, and then start Regedt32.
Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
Restart the computer.
 
Phew.. ive finally got it sorted. What was a simple drive changeover turned into a two day epic. In the end I started from scratch and reinstalled windows again. It seems the problem I was having was with my Dell2405 monitor, or its cardreader more specifically. I'd forgotten that the cardreader is allocated drive letters, and this caused the boot drive to be pushed along. To fix the problem, I simply unplugged the usb cable during the windows setup.
