I have successfully setup a dual boot system.

My original HDD contains XP and is designated C:

Vista is on a separate HDD and shows as G: when I'm in XP; it becomes C: when I boot to Vista. All OK so far.

Now, as the bootloader setup by Vista is on the XP HHD, how can I change the two HHDs so that Vista is the primary and the old XP drive can be converted to storage ie format the disk etc.?

What my question really is, if I remove the old XP drive, how do I now setup the MBR on the present Vista HDD so that it becomes C: ?

Bryan.

Correcting changes to the Partition/Disk structure

Where a partition or a hard drive has been added or removed and has caused the partition/disk structure to change, this can be corrected by running these commands in the order shown:

X:\>X:\boot\fixntfs.exe -lh -all (Where X: is the drive/partition on which the folder "boot" is to be found)

bcdedit /set {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} device partition=X: Changes boot partition of the OS whose GUID is indicated. (Where X: is new drive/partition required). Must be used together with the osdevice command below

bcdedit /set {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} osdevice partition=X: Changes boot partition of the OS whose GUID is indicated. (Where X: is new drive/partition required). Must be used together with the device command above
