Windows 7 - Dual Boot Vista/Win 7 - Can't Boot to Win 7 After Vista Reinstall

Actually it's a quad boot but I am sure the principle is the same.

I formatted and reinstalled my main Vista default system and now, although I can access the 2 Win 7 partitions OK, I can't boot into them.

I get a black screen with a lot of writing and...

windows\system32\winload.exe

status 0xC0000428

Windows cannot verify digital signature for this file.

Am using EasyBCD 2.0 and none of it's repair functions have helped.

I vaguely remember this happening a while back with XP/Win 7 dual boot on my netbook and I did something with the Win 7 DVD if I recall correctly....the trouble is I can't remember what.

Hi,

You may want to try Command Prompt @ Startup (option 2) and typing FIXMBR generally tends to FIX the Master Boot Record.

Hmm, not sure I like that 'Doing this could reduce functionality of your Vista partition' as that is my default/boot OS. I could end up with no access to any OS. Also don't forget I can't get into the Windows 7 partition at all except to look at its contents, so I can't do anything IN Win 7.

Let me think about it...;-)

If you have a Windows 7 boot DVD you can then access the Startup Recovery Console

I do have that but not sure what to do with it...and I don't want to lose access to my Vista. Vista Main is where all the boot records are kept. I can access Vista Main and Vista Test, it's just the Win 7's that I can look at but not boot into even though I added them correctly in EasyBCD..

As I don't dual boot I can't really comment much more than...The startup repair should detect all OS's and perform the repair based on the information gathered.

Thanks, I'll take a look at it when I get a few moments spare.

Which OS is on Disk 0, Partition 1?

Vista. 2 HDD's, 2 partitions each, Vista Main, Vista Test, Win 7 Main and Win 7 Test in that order.

If you remove Disk 0, will both Windows 7 installs on Disk1 boot?
