Window 7 - Windows 8 Dual Boot probem -- SOLVED !

Question

I followed the instructions to the letter from the article (How to Dual-Boot Windows 7 and Windows 8 Side By Side)

PROBLEM:

Everything installed fine and Windows 8 boots up great and seems to run fine but when I try to boot into Windows 7 the screen goes black for a second and then the computer restarts (it doesn't even try to boot like maybe there’s a file missing from the win7 partition? its just a black screen for about 10 seconds then restart

Before I installed win8 Win7 was working perfect and i even rebooted into win 7 after shrinking the volume just to make sure it was ok before installing 8 and it worked fine

But now I can’t boot into win 7 ...

All the files seem to be there and i can access them from within 8 but I can not boot win 7

DIAGNOSTIC:

·I tried changing the default OS and no difference. still no win 7 boot

·I have also run a complete chkdsk on both volumes and no errors

·Boot from 7 DVD  "startup repair" finds no problems & says last boot was successful 

·I checked the versions of winload.exe on both installs and they seem to be correct

·The disk management console in Windows 8 shows the correct info for both volumes:

         Volume Win7_64(D:)-Simple-Basic-NTFS--Healthy(System,Active,Primary Partition)
Volume Win8_64(c:)-Simple-Basic-NTFS--Healthy(Boot,Page File,Crash Dump,Primary Partition)

·   When running the "bcdedit" tool this is what it says: (Looks fine to me)

C:\Windows\system32>bcdedit

STATUS:

Windows 7 wont even try to boot just a blank screen for about 10 seconds then it restarts

------------------------------------------------------------

ANY help would be appreciated (its got to be something simple)

------------------------------------------------------------

UPDATE:  SOLUTION

I replaced the following two files with backup copies that I had saved just to see what would happen

    Filename:  :Windows\System32\winload.exe

    Filename:  :Windows\System32\winresume.exe

 

RESULT: = (PROBLEM SOLVED)

\Windows 7 and Windows 8 both now boot up perfectly like they are supposed to ...

-----------------------------------------

 I knew it was something simple :)

Answer 1

Personally I would ask this to be sorted guys - I see this issue a lot (I work with multiboot machines) and replacing files is not end user acceptable.
