I have yesterday uninstalled Ubuntu from my Dual-boot PC (Win 7). I first deleted the partitions used by Ubuntu using Windows, then wanted to restart but ofcourse
grub couldn't be found. And as if it couldn't get any better, I didn't have a recovery disc. So after using Hiren's BootCD 15.2 to boot up Windows, I made a restore-cd for Windows and then used that to reset the MBR. (I am aware this could have been done directly from HBCD, but I couldn't figure out how). So now Windows boots again, but I have quite a few partitions that are doing nothing now.
I read that using
GParted gives more options than the Windows disk manager or whatever, so I'm using Ubuntu on USB now so I can use this tool. This is what I get when opening it: http://i.imgur.com/0jcWfzn.jpg
Now, it's all one big drive, but I only want a C:/ (labeled OS) and a D:/ (labeled DATA), as I had before installing Ubuntu. The data on the other partitions I presume are purely from Ubuntu-data, and can therefore be deleted.
Since I've had enough misery only getting my MBR to work, I'm really want to make sure I don't mess my computer up again.
How do I start?
