Cannot format partition

Hello

My PC is on dual boot(both 7), and I want to remove the other now. But when I tried to format the partition, a message appear:

Windows cannot format this drive. Quit any disk utilities or other programs that are using this drive, and make sure that no window is displaying the contents of the drive. Then try formatting again.

I tried it in Safe Mode and I had no success.

The disk is NTFS.

I also removed the boot for the other 7.

Change the default operating system to MS windows Vista and click OK also startup and recovery.

Hello,

Try this artilce http://mintywhite.com/windows-7/7maintenance/remove-windows-7-from-dual-boot-with-vista/ it's for Windows Vista it should be the same for Windows 7 as well.

Hope this helps !

It's not working, same thing happens.

By the way, this is a laptop.
