I recently rest Windows 10 installation. Was working fine. But when i used Ccleaner to remove old windows files, it will no longer boot. (Just a blck screen after boot logo, before logon screen). Luckily i have dual boot and able to boot into other Windows 10. No how do i repair my original Windows installation? (DISM?) Update: I tried using 'repair image' in DISM++, but it fails with error "0x800f081f" How to run DISM command to repair windows installation and specify source for files?
source:WIM:X . X=where you mounted win 10. Hey MUBA, better wait for someone else, not sure exact line with dual and don't want you to have a problem . Sorry. Online line is for if the system is on online but you are still pointing it to a image off line for repair. Have you tried the simple method of just booting from an ISO and using windows repair. Not sure why everyone turns windows into linux, with commands when it's designed to be so simple. You don't need CCleaner, just use disk cleanup then use cleanup sys files.
Try mounting the broken windows partition on Windows then type (replace ? with drive letter) Code: bcdboot ?:\windows
Actualy i can boot into that windows, but after boot logo, screen goes black, no cursor, no HDD activity, nothing.
Boot into other Windows OS. Start powershell in admin mode. Type diskpart then press enter, type list disk, select disk (# of non bootables OS.) Clean. Create part pri. Select part 1. format fs=ntfs quick. assign. active. exit. imagex /apply X:\sources\install.wim 1 Z:\. Then start easybcd. Do steps to boot to new OS install. Save. Reboot.
When ever I have boot problems in any of my dual boot systems I boot w/ the OS DVD & & choose repair startup, sometimes one needs to run it 2x but it fixes my goofed-up boot screen choices.
