How to format system drive

Running two OS on my system.
Windows 7 on Drive(partition) C:
and Windows XP on Drive D:
now i wish to remove windows 7 from my system, got rid off the BOOT thing, but the windows files remain. System wont let me format the partition C:
what to do?


You need to edit the boot.ini file (could be hidden) on the D drive to look like this.

Since Windows 7 controlled the boot process it may have renamed the boot.ini file to boot.bak

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS=”C–XP” /noexecute=optin /fastdetect

Once you have done that use a partition manager like EASEUSPartitionMasterPro to set the D drive active and the other drive to normal (anything but active)

Reboot your computer and enter the BIOS to set your D drive as first to boot after your CD/DVD drive.

Incidentally in the above boot.ini example where you see C–XP ….. that is (or was) the name of my drive … you should put your own drive name there.

Once you get XP booting on it’s own you should be able to format the Windows 7 HD.
