I want to switch back to Windows, so I booted from a Windows installation DVD, but I can't format my hard drive with the setup. How to format my hard drive as ntfs so I can switch back to Windows?
This is probably because Windows uses a different filesystem than Ubuntu.
- Boot into the Ubuntu Live CD
- Open gParted (should be already installed)
- Shrink the current Ubuntu partition and create an empty NTFS partition (30 gigabytes should be enough) that will receive windows
- Using gParted, add a
bootflag to the new partition
- Apply your changes
- Next boot into the Windows installer and you should be able to install Windows on the new NTFS partition that you just created.
- After you have installed Windows, boot into Windows, delete the Ubuntu partition, and add the freed up space to your Windows partition.
