This question already has an answer here:

I had Windows 7 installed on my laptop, with hard drive partitioned. I installed Ubuntu formatting the drive as it didn't detect I had Windows 7 too already. It installed correctly, but now when I'm also trying to install Windows I don't have a drive of NTFS file system as it converted to ext4 completely (all 500 GB WD). Please help me in installing Windows too.

you can try to recover your files, see this question, but if you installed linux over windows, it's likely that your data is gone for good. –  Evandro Silva Nov 7 '12 at 17:21
    
To reinstall windows you'll need to create an NTFS partition (either the whole drive or just a part of it) and install windows onto that. –  jackweirdy Nov 7 '12 at 17:23

1 Answer 1

Boot from your installation media (live USB or live DVD). Run gparted and reduce the size of the Ubuntu partition. Add another partition and format it to NTFS).

Install Windows.

At this point, Windows will load but not Ubuntu, because Windows removes Grub the Ubuntu boot loader.

So again boot from your live USB or DVD and repair grub.

Install and run boot-repair and choose "recommended repair".
