Windows 7 dualboot with windows 8 problems

Hi,

I have partitioned my hard-drive and installed Windows 8 release preview, but now my windows 7 installation wont start to goes into automatic repair and when i try to do a system repair it oesnt find anything wrong.
I have checked disk management and it seems to have changed my drive letters also.

Has anyone had this problem and can give me advice.

Thanks

You will have to fix your dual-boot problem manually. From my experience (I always mess up my dual-boot some way or another lol ), automatic repair has never worked for me so I have to do everything by using command prompt. Since Windows 7 is more important than Windows 8, use the Windows 7 Setup DVD and:

1) Set Windows 7 as "Active" partition
2) Rebuild BCD
3) Fix MBR
4) Fix Boot

You can find easy instructions here. Bootmgr is missing - Fix - Windows 7 Forums

*Just remember that you won't see the nice blue metro style boot screen anymore, but you will still be able to boot to Windows 8 from the list. If you want to get the metro boot screen back, that is another thing but it is possible. I've done that before.

My Win7 and Win8 boot menu works peoperly but I've noticed tthat my Win7 profile has been corrupted and I'll need to repair it...

Hi, thank for the answers...
I have tried what was suggested, but now its coming up with File: \windows\system32\winlad.exe "The Digital Signature for this file couldn't be verified" Status.0xc0000428. It doesnt even let me get into the startup repair menu now.

Any suggestions would be appreciated.

If you can boot to either Windows 8 or 7:
Downlaod and install Visual BCD package.
Run "Dual-boot Repair" tool, click "Automatic Repair".

This will install all necessary boot files and make Windows 8 boot by default.

If Win 7 missing from boot-menu:
Run Visual BCD Editor, right-click in left pane, select "Create missing Windows loaders".
That's it.
