How to format Windows XP on a dual boot with windows 7.


I installed windows XP on my computer first and then later on I installed windows 7 ultimate 64bit.
Now I no longer have any use for my windows XP partition.
So I'd like to know how to format it and still be able to use my windows 7.
Both OS's have been installed on the same drive under a different partition.
I must also mention that I lost my original windows 7 install disk.
I've attached a print screen of my disk management.
I hope this is al the information you need.

If you wipe out XP, Windows 7 will not boot anymore.

If windows 7 is installed on either of those logical partitions it will have to be made Primary and marked active.

If you own a windows activation key, then download the proper iso and burn to dvd.

Easier just to properly prepare the drive and re install windows 7.

Or just re install Windows 7 on that C partition and wipe out the older install.

We see that D is Opstarten which seems to translate closest to Boot partition and means it is the Win7 partition presently booted, so Brian has it right that you'll need to first set partition D as Primary with Partition Wizard, before you can Mark Partition Active to run Startup Repair - Run 3 Separate Times until D becomes the System Active Boot partition proving it can boot itself. Then you can delete XP partition to recover its space into any other partition or create a new Partition there. How to extend partition easily with Partition Wizard - video help.

Be sure to back up your files first.

There are problems with having Win7 on D which happens when you install it from C and not from the booted disk as is correct. Most users don't want the OS on D due to limitations, so now might be a good time to Clean Reinstall Windows 7 as Brian suggests.

If you're OK with Win7 on D then you also have it on the slow end of the hard drive, which is another compelling reason to reinstall while deleting all partitions from the booted installer provided in the tutorial. However once you Delete XP you can also use Partition Wizard to Resize Partition - Video Help to grab E and then D to slide them over to the left, resize D or E's right border if you want either or both larger, or create a New partition to the right.

Feel free to ask back any questions or for more specific steps to do exactly what you decide. This is the only site on the web that helps with thousands of these complicated partitioning operations, and we've never had a failure yet using PW boot disk.

Back up files separately, System image to external or other HD. I'd use Macrium.
