using usb disc created on a UEFI laptop to reset an MBR pc
Hi I have a fairly old pc with a windows 10 pro OS with a version 22H2 Build19045.4123. I reset windows using a USB drive I created on a recently bought laptop running windows 10 Pro with UEFI. Since then the pc is running very poorly with some things it won't do like install the security update KB5034441 or reinstall the Proton VPN because I don't have the right credentials. Is there a way to get my MBR machine back without a clean install?
