I'm trying to replace GRUB2 with Windows' standard boot loader (bootmgr?), but I can't get it to work.
My Windows 7 install is in a single NTFS partition, which is marked as active (boot flag is set).
First, I tried the automatic repair with the install disk, but it didn't detect any problems. Then I ran bootrec /fixmbr and bootrec /fixboot, but all I got was a black screen at boot with a blinking cursor.
After that I created a boot partition for GRUB2, I figured, at least I can use it to chainload, but it give me a "disk reading error". If I used GRUB's ntldr loader, than I got error 0xc0000225 (some sort of BCD error). I tried to rebuild the BCD from the rescue environment, and it was successful, but the error didn't go away.
Update: I've tried to rebuild the BCD, but nothing changed...
