Windows 7: Win 7 Upgrade 7100 to 7600

Win 7 Upgrade 7100 to 7600

Hello, i have found it is possible to upgrade Windows 7 RC 7100 to Final version 7600 only changing Cversion file Located at the Dvd.

So i decied to try; since i have 2 partitions of windows 7 Rc 7100, i did it on the 40gb HDD first, everything worked just fine, the upgrade was successful.

but when i tried to update my 1tb HDD wich have 2 partitions, one for data and the other one for windows + instalations, my screen just turns black with an intermittent " - " at the left upper corner, this occurs at the last stage of the upgrade where files are transfered.

i know this wouldn`t happen with a clean instalation of windows, but i really don`t want to install all over again, i have made a lot of changes to the system + installations that i don`t want to lose and i don`t have enough space to backup all the data.

i would like to know if you could help me out with this problem, i have been thinking its maybe a problem with some driver, because i had the same issue months ago when i tried to update my Geforce Drivers, The screen turns black with the white dot at the corner, so i went back to my old driver.

I would suspect you are on the right track with the video driver.Dl a fresh copy and install it in safe mode.

Check the logs located here:
C:\$WINDOWS.~BT\Sources\Panther\setuperr.log

C:\$WINDOWS.~BT\Sources\Panther\setupact.log
C:\$WINDOWS.~BT\Sources\Panther\miglog.xml
C:\$WINDOWS.~BT\Sources\Panther\setupapi\setupapi.dev.log
C:\$WINDOWS.~BT\Sources\Panther\setupapi\setupapi.app.log
C:\$WINDOWS.~BT\Sources\Panther\PreGatherPnPList.log
C:\$WINDOWS.~BT\Sources\Panther\PostGatherPnPList.log

The last entry should provide clue to what is causing failure. Likely video card driver. Either uninstall it, update or roll it back.

Did you disconnect the 40gb HD when you did the 1tb HD ?

Thanks for fast response.

i didn`t disconnect the 40Gb HDD to upgrade the 1tb HDD because i didn`t need to disconnect the 1tb to upgrade the 40gb; DocBrown do u recommend me to disconnect the other HDD?

i checked the files gregrocker told me to, but i can`t fully understand the meaning of those files, i think the problem is some missing driver, but i don`t know wich one is it.

so maybe you could check those files:

in the meantime i`ll try to delete 3d drivers and upgrade in safe mode as zigzag3143 told me to.

I couldn`t upgrade in safe mode.

Windows menssage:

Windows cannot be upgraded while running in safe mode. to upgrade windows needs to be restarted and running normaly.

now i don`t know what to do, i`ll be waiting answers, thank you all.

Uninstall the Gforce drivers so it defaults to Windows drivers, unplug 1tb HD and try again.

Also use Clean Boot: How to Troubleshoot a Problem by Performing a Clean Startup in Windows 7 or Vista

Post back exact fail message.

You may need to do a clean install.

I disconnected the 40 Gb HDD wich already have Windows 7 7600 and ran Registrybooster 2010 to clean up the system.

This time i had some progress, the last stage of intslation reached 50% without any black screen, this time the problem was the instalation froze.

this time i`ll try to ran Tuneup utility before upgrade.

if you have any other ideas, just let me know, thanks.

The only clean up utilities I would run is CCleaner (Run Cleaner and Registry tab) and Auslogics Defraggers - both state of the art apps which are used by many or most pro's.

If you are unable to in-place Upgrade, then wipe your HD using DBAN and format using Windows 7 DVD before installing. Clean Install with a Upgrade Windows 7 Version

Nothing seemed to work until 03/28/10 (just 1 day before Windows 7 expires xD) when i decided to remplace my 3d for the one in my other pc; the upgrade ran just fine.

i had some trouble after the upgrade with video drivers when i tried put back my 3d, but now everything it is working.

Thank you very much all you you for helping me out with this problem.
