A few months ago I made my laptop a dual boot install with Windows & and Ubuntu 10.04. I recently remembered why I dislike dual booting and decided to remove the ubuntu partition. I never use it. When I need Linux I either boot a Virtual Machine or else I ssh to one of my many Linux servers, there is just no good reason to have a dual boot linux system for me. The laptop was booting from Grub so if I would have just deleted the Linux partitions I would have been left with a unbootable system, so I had to rebuild the Windows & boot loader first.
Below I outline my steps for doing so:
Please Note: This method will only work if you can boot into Windows
1. Boot into your Windows Partition and download the tool Easybcd
2. Install the tool using all the default settings
3. Once finished start the EasyBCD software
4. Choose the selection which says “Manage Boot Loader”
5. Make sure the radio button for install the Vista boot loader is checked and the press the “Write MBR” button
6. Reboot and now grub should be gone and you should be booting straight into Windows again.
7. Lastly, use your preferred partitioning program to remove the Linux partitions and resize the NTFS partition so that you can recover all of your drive space.
