I know there are already a lot of posts about it but I didn't find anything similar to my problem.
I thought to give ubuntu 12.10 a try. Everything went fine until I reached the setup of Ubuntu through bootable USB. It wasn't recognizing my Windows 8 and only offered me to erase the HDD and install fresh which I didn't want.
I ended up installing Ubuntu only to find out that Windows 8 bootloader doesn't support Ubuntu and other Linux distributions. The installer kept giving me an error that my partition table requires me to create an extra partition of at least 1MB for booting or something like that. I created three partitions: one for swap, one for Ubuntu and a third one of 5 MB for booting. But it still didn't boot.
I used Boot-Repair in Ubuntu to install Grub 2 and everything finally started working.
Later I realized that Ubuntu was not working fine and it affected Windows too drastically slowing it down for some reason. So I wanted to remove Ubuntu and get back to the old bootloader. Now this is where the whole problem started. Most of the guides I found told me to use a recovery disk or full Windows 8 disk which I didn't have to I fell to easyBCD for fixing the MBR. I didn't make any mistake in the procedure and got no error but it didn't work either.
The next step was a recovery of my Windows 7 from OEM Recovery Partition hoping that it will overwrite the Bootloader too but it didn't. I've burned the recovery discs for Windows 7 and 8, and then try fixing that way. While making the recovery disk, I found out that for some reason Windows thinks that this system is Windows 8. I mean in the System Configuration, Boot tab it says "Windows 8(C:\Windows):Current OS;Default OS" and that's it nothing else even thought I'm running Windows 7. It erased the whole C drive in recovery. I tried to use that recovery disk but it gives the error regarding non-system disk. EasyBCD still doesn't seem to be working at all the GRUB just doesn't go away!
Please help me fix this.
