Windows 7: tried to install upgrade, after final reboot, no boot

Since you may need to reinstall 7 to overcome the GRUB corruption, you might consider deleting that EISA partition in the prime lower address, either extend Vista into that space (using Partition Wizard CD) or delete Vista and move or reinstall Win7 there.

But first try running Startup Repair 3 times to rewrite the MBR, after deleting that GRUB bootloader using EasyBCD.

If that fails, boot back into Repair Command Line and run "bootrec.exe /fixboot" and "bootrec.exe /fixmbr" then restart,

or if those don't work "Bootsect.exe /nt60 all /force".
There is no reason anymore to do all this, since fixing the mbr using bootsect.exe /nt60 sys already did the trick for me. But I doubt the grubloader is causing any problem. Easybcd itself put it there, it was put there after Vista but before the RC and there was never any problem booting the system. And there is no problem anymore now, either. I have a running windows 7 install, a running vista, and, if I want, ubuntu on an external drive. I see no reason to remove any component. Remember, before I repaired the MBR, I could not boot ANYthing. And after I repaired it, everything is back the way it was before the trouble started. I'm going to leave well enough alone... But thanks for your interest and follow-up. It certainly helped.

OK I thought you were experiencing abnormalities which surely would be caused by that GRUB bootloader.

DIdn't know you are still running Ubuntu from external - very cool.

Now I know why many are insisting they should be able to put Win7 on an external.
