On a Win10 system that won't boot up, the Win10 iso does not actually show the reset option like it should - the startup repair or uninstall upgrades won't do anything naturally either. Many people note that feature doesn't work - https://answers.microsoft.com/en-us/windows/forum/windows_10-update-winpc/no-option-for-reset-my-pc/283cd126-8970-44c9-a183-0ed3f8ac72c8
And chkdisk showed no disk errors. sfc or dism command does not work, as usual.
So could I look at the HDD, and the USB Windows iso drive contents while running Linux bootable drive, and find and copy files that someone/something moved or corrupted? This suggests that may be possible. Is there any tool to do this automatically?
