Windows 10: Use DISM to Repair Windows 10 Image
In that situation, it may be best to refresh Windows since it wouldn't affect your Windows 7 installation, and activation for a clean install of Windows 10 has been temporarily blocked by Microsoft for testing upgrades until the 29th.
As usual, you should always back up anything from Windows 7 you don't want to lose just to be extra safe.
Okay, thank you very much Brink!!
I will shutdown and unplug my Win 7 SSD now, and then I will refresh my 10240 installation. I have nothing to loose because Office 2016 is the only software I have installed. If it will go well, fine. If not I will delete the volumes of this Win 10 SSD, and wait for an official ISO (or reinstall if I won't get bored).
Nar, you'll want to leave Windows 7 connected. Otherwise, it may no longer include it in the "Choose an OS" screen at boot.
Back, after unplugging my Win 7 SSD and clearing CMOS.
I use F11 to select the boot disk drive so I never have this boot selection screen
Going for the Refresh now!! I hope the deletion of all system files and previous installations (full Disk Cleanup) won't affect the Refresh...
That would just do a reset instead of refresh, and basically be like a clean install.
Reset Windows 10
Well, well, well......
I'm back after a failed Refresh. lol.
It started to Refresh, I went in the other room, and after returning I saw a screen with a " " smiley mentioning an error and prompting me to search for the error "Inaccessible boot device"....
Then it reverted the changes and now I am back to where I started again. So, the conclusion is that after a full Disk Cleanup no Refresh can be performed?
Going to clean install 10162 again, right now. Then I will wait for the upgrade, whenever it comes.
Before doing that if you like, refresh should work if the Windows 7 drive was connected if the Windows 7 drive was your boot drive.
Well, to be honest I would not like to risk my Windows 7 installation, my main OS I use for everything, for nothing in the world. The ONLY thing that nags me is that I would prefer to wipe this SSD's partitions/volumes via Win 7 Disk Management and NOT via the WIN 10 installer! But I am too bored to clear CMOS again and plug in Win 7 SSD and delete the volume and unplug, clear CMOS blah-blah-blah...................
So I will leave the drive as it is, even not in SATA position_0, but in SATA_1 as it is now, and I'll just plug in my usb with the ISO, and after 10' my other USB with the drivers, and I'm done.
Glad that I tried these procedures though. For sure I'll need them since 10 will be my main OS after a couple of days.
Thank you very much, Brink!
PS: Dunno if Win 7 drive was my boot drive. All I know is normally I boot in 7 and whenever I wished so, I was pressing F11 and selecting the other disk and booting to 10.
I can understand that. I hope it goes smoothly.
If you have a pc that has a clean result from sfc /scannow and from Dism /Online /Cleanup-Image /RestoreHealth, then I strongly recommend you backup your \windows\winsxs folder to another drive, usb stick, or dvd. For windows 7 - 10.
Three times for three different pc's (windows 7 Home, windows 8.1Pro and Windows 10 Home) I've had problems where Dism /Online /Cleanup-Image /RestoreHealth failed,
even failed using the mounted drive image and doing both the following commands.
Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:Full Path to install.esd file:1 /limitaccess
Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:Full Path to install.wim file:1 /limitaccess.
Each time I had a backup of a clean winsxs folder on another drive for that pc, I was able to use Dism /Online /Cleanup-Image /RestoreHealth /Source:drive:\WinSxS /LimitAccess, and for all three machines, the problems were corrected.
One of the three machines was an upgraded windows 7 to windows 10, I backed up the winsxs after the 10 upgrade and updates were installed and the system booted. In just a day I needed the clean winsxs as the live one became messed up and none of the above commands would work except the one pointing to my backed up winsxs folder.
I now keep a copy of the winsxs folder for all my computers in different locations just in case.
All three pc's now run clean for sfc /scannow and Dism /Online /Cleanup-Image /RestoreHealth.
