I have dual booted Ubuntu with Windows 7. I wanted to uninstall Ubuntu. So as per an answer for one of the related questions on this site I did the following:
- Deleted the Ubuntu Partition through Windows.
- As per the answer now I was supposed to boot Windows from USB & then do "repair startup".
But Windows could not find any problem hence nothing was done.
So when my laptop booted normally (i.e. from HDD) it was showing some error like
GRUB:/ unknown file system. I dont remember the exact words but it was something like this.
Thus I couldn't boot windows neither Ubuntu. So again I had to install Ubuntu.
But now my question is how do I remove Ubuntu so that my laptop returns to the previous state of installing Ubuntu?
UPDATE: Seems that it wasnt on this site. My mistake 😛 .Here is the link http://www.makeuseof.com/tag/how-to-safely-uninstall-ubuntu-in-windows-dual-boot-environment/
