Repair Install Windows 10 with an In-place Upgrade  

It seems I may have reached the point now where this will be the option to take. First I have been trying to debug and rebuild the BCD store from the latest triple boot project with three different versions of Windows 10/7Dual Boot Presently seen to add in the latest W11 Pro. Before this came up 10 stopped seeing additional hard drives and even detecting USB devices for some unknown reason but now made a comeback until the 10 Drive became unbootable?
The 7 drive had been the Host/Boot drive for some time until seeing if W11 would go on leading to the likely need to see the Repair by Upgrade install take place. Certain programs if lost won't be able to be reinstalled from start. As for select files those are presently shared between drives to prevent losses from any possible situation including drive failure or accidental deletion.

Before I get totally lost and forget to ask one particular question here would be a Repair Install seen if either a dvd purchased for the initial retail installation or unpacking an ISO download to manually browse the root of C: would also be able to set the upgrade to repair install in motion or not? For one recent test install of Windows an ISO disk was unpacked to an empty drive made bootable and saw Windows see a temp install go on it!
It took a bit more time as the process ran slower note. But there were no errors to find with that copy of Windows otherwise running smooth despite not seeing updated drivers other then what was available backed up on another drive. The wait for the language selection screen followed by another long wait for the product key prompting to then wait a bit longer even to finally reach the desktop would otherwise be an annoyance for some.

Can i prepare the ISO on one windows 10 Pro machine and use it on another Windows 10 Pro machine ?

Hello,

Yes, you sure can.

I screwed up my ProgramFiles\WindowsApps folder by taking ownership of it and trying to restore ownership to Trusted Installers. Now, when I try to launch anything in that folder, I get a "The process has no package identity" error. Will an in place repair fix this?

Hello,

Since it's a system folder, it should.

I tried in-place repair twice, doing DISM and SFC before the second one. Both times it stalled at 31% for a few hours. Short of a clean install, is there anything else I can try?

You need to disable 3rd party... AV, firewall and encryption software.
The ISO you use must be the same language as the Windows installed version.
Tell it to skip doing updates, as well. Do any updates before or after the In-Place Upgrade... not during.

Sometimes, the In-Place Upgrade has trouble on a prebuilt computer, like a laptop.

There may be some Lenovo Utility causing the problem?
