Remove XP from dual boot with Windows 7

The C: can't be "System Active" as it's on an Extended partition / Logical drive.

The OP can use Option Four of this tutorial at the link below to safely convert C: to a Primary partition so the "System" boot files can be stored on the Windows 7 C: partition; be sure to use the boot CD and not the installed version of Partition Wizard for this.

Partition Wizard : Use the Bootable CD

First download the Partition Wizard Bootable Disk (PWBD) ISO file to the desktop, be sure to get the PWBD and not the installed version; scroll down to see the download link for the Bootable CD ISO file at this link below.

Then use ImgBurn to burn the ISO to a CD, at no greater than 4x speed with a verify; it was designed for use and works best from a CD rather than a DVD; then boot the created CD to make the changes, it doesn't take any input from the user to setup, just relax and let it load.

After C: is a Primary partition we can help get the "System" boot files created to that partition.

I have never gotten Partition Wizard to convert Logical to Primary with more than one Logical sub-partition.

I've done it more times than I could count working on these and many others.

System Reserved : Multi Boot from Logical Partitions

Partition / Extended : Logical Drives

It would best OP to unplug the two other HD's, when doing any repairs.

You have an excellent point there, just to be safe.
