    Dual-Boot System upgraded to Windows 10, now Win7 gives LogON error


    I have a dual boot system in the following configuration:

    HDD-0 = Win7 OS, HDD-1 = Win7 OS, WinXP OS. I have successfully booted into each of these operating systems - and the Win7 OS on HDD-1 is an exact clone of the primary OS on HDD-0.

    I just upgraded the Win7 OS on HDD-0 to Windows 10 using the "Get Windows 10" process. I now get the new blue Boot Manger screen with all three OS's listed and I can successfully boot into Windows 10 and Windows XP. But I cannot boot into the Win7 OS on HDD-1 (which I could before the Windows 10 upgrade). How the upgrade even knew about the other copy of Windows 7, since it was not active and lives on another HDD is beyond me.

    One strange thing - if I do a cold startup (power on) I get the new Boot Manger screen. But if I do a Restart from Windows 10, I get the old, black & white boot manger screen - and it does list all three OS's correctly, too.

    The error message I get when trying to open (boot) the Windows 7 OS is: "LogonUI.exc - Entry point not found. RtlReleasePath could not be located in the ntdll.dll" And, like others, I now get the black screen with "Windows 7, Build 7601 This copy of Windows is not genuine (but it was yesterday before the Windows 10 upgrade on the other HDD).

    And like others, I can start the Crtl+Alt+Del to get the screen with users, Task Manger, etc. And, I can run all my applications by manually starting them in a New Task and browsing to the exe file - like Firefox.exe or Word.exe So, it looks like Windows 7 started and may be running. I just can't get into it.

    I understand this may have something to do with the faster boot that was introduced in Windows 8 since the problem started around then.


    I think both issues, the LogOn and the "Not Genuine" are both related to the Entry Point no located in the ntdll.dll.


    At this point I really don't want to reload Windows 7 since it appears to be running and all the apps can be run manually.


    All this happened after the upgrade of the other Win7 on HDD-0.


    I'm going to post this in the Sevenforums, too, since it may be related to that OS as well.



    Thanks

    :)

  2. Windows 7 not working in Windows 10 dual boot system and blue screen appears

    Original Title: windows 7 and 10 dual booting

    I recently tried to dual boot win7 and win10 to test out win10, i formatted and changed 1 hdd from mbr to gpt, i shrank a partition for win10 (50gb) and installed it without any hiccups, i booted up win10 no problems and the 1st couple of times switching
    to win7 was fine too, but after those 2 times when trying to boot win7my mouse and keyboard became unresponsive, i couldnt login or shutdown or restart without pressing it on my case. I tried disabling the xHCI in the bios, which worked for that 1 time booting
    win7. After that, the only way i could boot win7 and logon was if i disconnected my hdd with win10 on it. So i decided to cut my losses but without being able to logon win7 i used the win10 installation from the boot menu to reformat the hdd with win10 on
    it, now i get the blue screen with error code 0xc0000225 on it, the same as having my hdd with win10 on it disconnected. How can i get rid of this? Basically going back to how things were before the win10 install. I didnt backup any of my drives since they
    were all pretty much full, but the hdd that had win10 on it is completely empty and seperate from win7.

    ual boot system upgrade to windows 10

    Thanks Jessen for the hint. I was expecting a yes or no answer, since I already have a dual boot system(xp+win7), and if I upgrade win10 from win7 boot, would win7 be replaced by win10 and becomes a (xp+win10) dual boot system?

    But it looks more complicated than I thought, should I check current system has xp and win7 are installed in DIFFERENT partitions, otherwise xp would be gone after win7 is upgraded to win10 if xp and win7 are in SAME partition?

    Do you still have the Windows 7 installation media (USB or DVD)? I suspect that when you cloned the HDD-0 Windows 7 to HDD-1 and ran them side by side some pointers in the HDD-1 Windows 7 were still pointing to and actually using the Windows 7 on HDD-0. What I would try is from within Windows 7 run the setup.exe on your Windows 7 installation media, in effect doing an in place upgrade of Windows 7 to Windows 7. That might re-install some of those target files and pointers to their proper locations on HDD-1.

    The Windows 10 install was aware of the Windows 7 on HDD-1 because of the pointer to it that was contained in the BCD store (boot files).

    Your "cold startup" from Windows 10 shutdown is not as "cold" as you think it is. It is actually a hybrid shutdown recovery, very similar to hibernation. The "restart" from the Windows 10 power icon is actually a true all the way shutdown to bios and restart, that's why you see the different initial boot menu. You might have less problems if you turn fast startup off in Windows 10.

    Thanks for the reply - I do have my original Windows 7 Pro disk; if I run the setup.exe on the DVD how will that affect all the currently installed applications (that appear to run just fine from the Task Manager)? I'm just so convinced that Windows 7 seems to be running, just not passing the LogonUI successfully, that I don't want to do a full reinstall.

    It should not affect all your currently installed applications or user data files.

    This article contains a very thorough process, but most of the preparation steps are not really required (but good to do anyway):

    This is a simplified tutorial - just do it in Windows 7 with the Windows 7 DVD instead of Windows 10:

    Hi - am I correct that since I can't get to the Optical Drive from my Windows 7 in its current state, that I should boot from the Installation Disk? How will it find the Windows 7 OS that I want to repair?

    NO! Do not boot from the Installation Disk! What you can do is in Windows 10 copy all the files from the Windows 7 installation disk to a folder that Windows 7 has access to, like create a new folder Win7 and just dump all the files from the DVD into it. Then from within Windows 7, run setup.exe from the folder you copied the files to.

    Booting from the Windows 7 disk will cause you to do a clean install and, at best, copy all your old Windows 7 stuff to windows.old folder and at worst wipe it out completely.

    Got it - copying all the files & folders from the Windows 7 Pro installation disk to a folder in Windows 10 - then move that folder to the Windows 7 on HDD-1 and boot into that OS and use the Task Manager to find and run the startup.exe file. And when the window opens select "Upgrade"

    Sound right? (And keep my fingers crossed!)

    Well, no luck. Get the following two error messages:

    api-ms-win-core-com-midlproxystub-l1-1-0.dll is missing

    Ordinal 854 Not Located in iertutil.dll

    Next message is "to upgrade Windows, the User, Program Files & Windows need to be on the same partition. Well, they are....



    Still bugs me that I can run from the Task Manager and not the usual desktop. Looks like a logonUI.exe issue again.

    Two thoughts :

    When running in the Windows 7, is it C: drive, or something else? If it isn't C: drive, then I would change the drive letter to C:. You will have to do that while booted in Windows 7. Might have to install MiniTool Partition Wizard Free to do it.

    Second thought is to create a new user account in Windows 7 and see if the problems exist in the new account.

    Dual-Boot System upgraded to Windows 10, now Win7 gives LogON error

    Now this is interesting. Before the Windows 10 upgrade the drives were labled:
    C: Win7 (HDD-0), D: WinXP, G: Win7 (HDD-1) with the C Drive being flagged with the Windows 7 Icon.

    If I booted into WinXP the drives were relabled:
    C: WinXP, G: Win7 (HDD-1) no change, and J: Win7 (HDD-0) with C Drive being flagged with the Windows XP Icon.

    And if I booted into the HDD-1 copy of Windows 7:
    C: Win7 (HDD-1), D: WinXP and J: Win7 (HDD-0)

    So, booting changed the drive of the desired OS to C: each time and moved the OS that was C to another drive letter.

    After the Windows 10 upgrade the drives are labeled:

    C: Win10, D: WinXP, G: Win7

    Booting to Win10 and WinXP does change the active OS to C.

    But booting to Win7 does not rearrange the drive letters; in other words, Win7 stays G: not C:

    I don't know why, the boot manger looks correct (from EasyBCD 2.3):

    There are a total of 3 entries listed in the bootloader.

    Default: Windows 10
    Timeout: 10 seconds
    Boot Drive: C:\

    Entry #1
    Name: Windows 10
    BCD ID: {current}
    Drive: C:\
    Bootloader Path: \WINDOWS\system32\winload.exe

    Entry #2
    Name: Microsoft Windows 7 1-Win7
    BCD ID: {f510424d-7031-11e4-8421-00219b205fea}
    Drive: G:\
    Bootloader Path: \Windows\system32\winload.exe

    Entry #3
    Name: Microsoft Windows XP
    BCD ID: {f510424e-7031-11e4-8421-00219b205fea}
    Drive: D:\
    Bootloader Path: \NST\ntldr


    Thoughts as to why Win7 does not get the C: drive letter when I boot to it and it appears to run but with the LogonUI error.

    As an aside, I no longer have the "not genuine" message - I ran a Cmd of slmgr -rearm and "maybe" that resolved the Build 7601 issue. But I still have a black screen right after the Error of LogonUI.exe and then the blue Welcome screen, it goes black with another LogonUI error.

    Could it be that when you booted into HDD-1 Windows 7 before the upgrade to Windows 10 that your HDD-1 Windows 7 was actually G: drive and the C: drive was pointing back to the original HDD-0 Windows 7? I think your problems are related to drive letter assignments. Windows 7 is looking for files that were originally on the HDD-0 the whole time and you took those files away when upgraded to Windows 10.

    Well, I don't think so -- the reason is that the Win7 on C had a different desktop and shortcuts than the Win7 on G (Actually, I put an empty folder on each desktop (O-Win7 & 1-Win7, 0-WinXP, 1-WinXP) so by looking at the desktop I knew which OS was booted.

    Also, its strange but the Windows folder in Win7 shows 130,592 Files and 28,007 folders but the Windows.old folder left by Windows 10 upgrade shows 108,783 files and 23, 058 folders. Don't know why the difference.

    Question: And maybe this is just old thinking, but does Windows 7 have a "Repair Console" or was that way back in Windows XP.

    I guess this may all come down to having to format that G partiton and reinstall Windows 7 & all the associated Applications. I know I can get the User files before the format - it just bugs me that this LogonUI error seems to be the stumbling point and I can run everything from the Task Manager.

    If it comes to the reinstall, the machine originally came with Windows Home and I upgraded to Windows Pro. Can the reinstall be from the Windows Pro disk, even though it says Upgrade?

    I'll check for your reply but am going to call it quits for today. I've booted so many times I can't see straight.

    If your "name" is an indication, "Thank You for your Service". Have a great Thanksgiving!

    If you keep thinking about this issue, please let me know.

    Thanks
