I had a Windows 7/Ubuntu 12 dual boot and I decided to clean install Windows 8 over them.
The problem is that after I deleted all partitions and installed windows I was getting an "Operation system not found", however after an "enter" the system will normally boot into Windows 8.
I realized that Windows did their trick and put the system (not partition anymore?!?) "tag" (Disk Management) on my media hard drive.
After trying to fix the boot/mbr to be able to boot from my main drive the "Operation system not found" changed to the "grub rescue>" prompt. I know that I cannot use that because I have killed the grub files. Windows can still boot as long as I choose to boot from the media drive.
The question is, is there any way to move the "system", whatever it is now, to the main drive and have the PC boot from there, while making grub disappear? And if that is possible after that, can I just make the Media drive inactive or I will have to somehow remove the "system" tag?
