I just finished installing Windows 7 x64 7068. This PC already has XP on a different drive (not just different partition). The Windows 7 drive is set to boot first in BIOS.
After the first reboot I got the "BOOTMGR is missing, ctrl+alt+del to restart" message. If I boot with the XP drive, there is an option for Windows 7 and I can log on with that.
I used the startup repair tool on Windows 7 DVD but it did not detect any problem. Tried easyBCD to reinstall the Vista bootloader but that didn't fix it either.
How can I fix this? And how should I install Windows 7 so that each drive can boot on its own? I can select which drive to boot quickly after POST so I don't want the 2 OSes to tangle up like that
