Well, I decided to give Ubuntu 12.10 a try but really isn't for me, mostly because I'm a gamer at heart and the game selection on Linux is very limited. :P
I want to revert back to Windows 7 but I can't seem to be able to access the recovery partition on my Desktop. It's an Acer, so the Alt + F10 combo should trigger the recovery management during the boot, but for some reason it doesn't: the PC goes straight into Ubuntu.
I've tried reinstalling Windows from a DVD but it looks like the computer is ignoring whatever boot command I give it. I changed the boot order inside the BIOS, I tried to directly tell the PC (with the built in function) to boot from the DVD but nothing: the PC won't boot anything but Ubuntu.
I can tell the recovery partition is still there because the disk management says that out of my 1TB, 60GB are already occupied by stuff, and I don't think Ubuntu takes that much space. So, something must have screwed up the boot system.
Any ideas on how could I fix this? Thanks in advance.
edit: I should have added that Ubuntu 12.10 is the only OS installed on the HDD at the moment. I'd like to reinstall Windows from either the recovery partition or the DVD but they just won't boot up! The PC goes straight into Ubuntu, regardless of what I do/click.
