I fucked it up again, but managed to fix it. Bad news though, my new mouse came and it doesn't work. So I won't likely be able to play again until the 9th of Jan
Get a Vista or 7 CD.
Boot into it.
Open Command Prompt.
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
bootrec /scanos
Bootloader should be fixed, flag Windows 7 partition as active.
diskpart
list disk
select disk <ID of the disk your Windows 7 partition is on>
list partition
select partition <ID of the partition of Windows 7>
active
exit
I had to do something similar to this, the problem was that my windows 7 installation disk didn't have the recovery options, it only had the install one. Managed to get hold of a separate recovery iso though, burned that and bob's your uncle.
