I want to uninstall Ubuntu 12.10. I installed Ubuntu (from a usb/cd) using the option "Install along with Windows 7". Windows 7 is installed as usual in C:\ and Ubuntu is installed in some other drive.
How do I uninstall Ubuntu from this setup?
Well, you must first fix your MBR
so that windows7 boot loader can act. in order to do that there is a nice tool in HirenCD named Fix MBR
. Try to download it and use it. Then you must format your Ubuntu partition with any tools you know. There are also some partitioning tools in that CD, I recommend Paragon partition manager
;)
Back everything up, and then just delete the linux partition(s) using Disk Management. After that, load a Windows CD, or HBCD, and repair the Master Boot Record. Finally, you can reclaim the space for Windows, also using Disk Management.
