Help! If i upgrade from Windows 7 to 8 using the upgrade assistant and choose to overwrite Windows 7 and delete all files, will the current MSR (Grub2) be replaced with the Windows MSR? i sure hope so couse Grub has been a pain in the ass since i upgraded to Ubuntu 12.10 and everything stoped working. I fixed the problem with Grub using "Boot-repair" after sitting next to my other computer throug the hole day trying to find a solution, and now i just want it as far away as possible!
You might want to try Grub2Win which is available here http://sourceforge.net/projects/grub2win
It uses the native Windows bootloader and is configured from windows. It will allow you to dual-boot Linux easily.
