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

    General discussion

  • 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

    Windows Boot Manager

    identifier {bootmgr}

    device partition=D:

    description Windows Boot Manager

    locale en-US

    displayorder {current}

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

    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 :)

  • 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.
