Yep, I'm in the middle of doing that right now. Thanks :wink:

Addendum:

The weirdest thing...I just discovered this in the last few minutes as I hadn't even tried to boot into Win 7 all day. It wont do - getting a black screen stating it can't proceed and something about..


Windows\system32\winlooad.exe
Status 0xC0000428
Windows Cannot verify the digital signature for this file.

My EasyBCD setup looks to be OK..

There are a total of 4 entries listed in the bootloader.

We've seen this many times - another MS screw-up. The Vista bootloader can't boot 7, only the other way around.

EasyBCD | Re-create boot files

should do the trick.


Addendum:


errrr no, it may not fix it. It might end up re-copying the same Vista bootloader. Doesn't hurt to try, though.


You can fix it yourself by replacing BOOTMGR on the boot partition with a BOOTMGR possibly found in either \Windows\Boot\ or one of its children on the 7 drive.

Thanks. I tried the first option already and there is no BOOTMGR in that section that I can find, hidden and system files visible.
It's maddening to be able to access the partitions yet not to boot into them. I vaguely remember this happening ages ago with XP/Vista and I did something with the recovery console from the Vista DVD, but I could be wrong.

I'll do some more digging online...and in my memory banks. I probably printed out the instructions somewhere, but trying to find them is another matter.

Is anything here an option without losing the Vista boot choices?

Recovering the Vista Bootloader from the DVD - NeoSmart Technologies Wiki

Assuming I use the Win 7 DVD.

Addendum:

Thanks everyone for your help. I finally plucked up the courage, inserted my Win 7 SP1 DVD and restarted and using the Repair option Windows repaired some things on its own without me prompting it to, but I couldn't yet boot into Windows 7, so restarted and this time waited until the automatic scan for installed Windows versions had finished and chose Startup Repair, it fixed something and said the I should return to that menu after a reboot so did it all again and hey presto, I now have my quad boot back safe and sound.

This is what my EasyBCD menu looks like now and I noticed an immediate change in the BCD ID numbers which previously were all the same (hence my problem):

There are a total of 4 entries listed in the bootloader.

Default: Vista Ult SP2 Main
Timeout: 30 seconds
Boot Drive: C:\

Entry #1
Name: Vista Ult SP2 Main
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.exe

Entry #2
Name: Vista Ult SP2 Test
BCD ID: {4246d21d-6dac-11e0-a583-002618086fdb}
Drive: D:\
Bootloader Path: \Windows\system32\winload.exe

Entry #3
Name: Win 7 Ult SP1 Main
BCD ID: {4246d21e-6dac-11e0-a583-002618086fdb}
Drive: L:\
Bootloader Path: \Windows\system32\winload.exe

Entry #4
Name: Win 7 Ult SP1 Test
BCD ID: {4246d21f-6dac-11e0-a583-002618086fdb}
Drive: M:\
Bootloader Path: \Windows\system32\winload.exe
Addendum:

By the way, this served another useful purpose....I discovered that my Win 7 SP1 DVD was badly scratched so will do another. Thank goodness it worked regardless.
