Win. 10 Repair/Replace Corrupted Files
BretMan:
To double check with you before I do that:
1- I insert my disk with Windows 10 Repair Install with an In-Place Upgrade (downloaded Sept. 14, 2016) into my D: disk drive.
2- Should I be in Safe Mode?
3- Do I need to turn off Windows Defender?
4- In CMD (Administrator) I enter "sfc_/scannow_/offbootdir=D:\_/offwindir=D:\Windows" where D: is where the disk is.
5- Just let it run until completion on its own, then post the resulting CBS log?

No, you need to go into the BIOS to change the Boot order so that it checks the disk drive first.
If it at first ignores it and boots normally to Windows then you will need to turn off fast start up in the Power Options.
You can get into the BIOS by in Windows, by pressing and holding F2 throughout a Restart until the BIOS appears on the screen.
Use your cursor keys to move along to the Boot tab then use the cursor keys again to select the CD/DVD drive, using F5 or F6 to move it to the top.
Insert the disk then press F10 to Save and Exit - press enter to confirm.
You should be momentarily prompted to press any key to boot from CD/DVD and when you get the Install screen, select Repair your computer.
You may get a window popping up about having booted up with an install disk to perform a custom install and if you intended to just do a repair install, then to insert the disk after booting up Windows - just proceed as for the custom install where you will see the link to Repair your computer down on the left.
You get pretty much the same menu as you would if you had gone in through Settings/Update & Security/Recovery to select the Command Prompt.
It won't produce a CBS log.
BretMan:
Whaaaat??? LOL, I'm so confused now ...
Are you now saying I should forget about running the "sfc_/scannow_/offbootdir=D:\_/offwindir=D:\Windows " command in the CMD window with the disk in the D: drive and instead just set the BIOS to boot from the DVD first (that is already my default setting) and just run the repair option from the disk?
Boggin:
Yes - what happens is that you are booting up outside of Windows by booting up with the install disk and that cmd will then check your installed volume against the incorrupt source of the disk and repair as necessary.
I think it is the level of manifest corruption that is stopping you from performing a repair install.
While a sfc /scannow doesn't scan all files as I've been told by Shane, hopefully the offboot one will repair your corrupt volume.
When complete, enter exit to close the cmd window, remove the disk then restart.
If it has accomplished anything then a normal sfc /scannow should come up clean - otherwise it's the clean install.
BretMan:
Ok. I think I understand now. So what I do exactly is put the disk in drive D: then reboot and it will first boot to D: and therefore access the disk and ask if I want to do a repair or install. At that point I do nothing with the disk. I then go to Start>Commmand Prompt (Admin) and enter "sfc_/scannow_/offbootdir=D:\_/offwindir=D:\Windows " in the CMD window and let that run until completion. Correct?
If not, what are the correct steps.
