I have a laptop (aspire 5) and after pressing the "restart now" button on windows update, it had a screen saying "Undoing changes made to your computer..." and after a few minutes it goes to a blue screen (system service exception, Nfts.sys was affected) which restarts the laptop and starts this process again. I managed to be able to enter uefi, but I cannot boot into safe mode (the boot options is greyed out). What do I do? I'm thinking about installing a new SSD, but that should be a last resort.

    The registry or system file is corrupted. To get out of the repair loop you need to boot with a USB Recovery flash drive 10GB or more in size Fat32 formatted. Insert this (empty) drive in a USB2.0 port of another Windows PC (same Windows version as your laptop) and create the recovery drive (takes up to 30 minutes).

    Insert this USB drive in the USB2.0 port of your Aspire5 laptop and boot to BIOS with F2. Go to the Boot Devices screen and move the USB drive to the top of the list. If you do not see the USB flash drive on that screen you either used a USB3.2 port or you need to enable the F12 boot menu in the BIOS settings.

    If still not able to see the USB drive, take the drive out and insert it back in the other PC and check if the drive is detected there. You may have a bad USB drive. or the writing to USB failed. Create it again or get a new USB flash drive.

    Once you have moved the USB drive to the top of the list in BIOS of the Aspire5, save settings on exit and reboot without pressing F2 and with the USB drive inserted.

    You will get the blue WindowsRe screen with the Troubleshoot menu, go to Advanced and first select the Command Prompt option.
    In Command Prompt, type: copy c:\windows\system32\config\RegBack* c:\windows\system32\config

    and press Enter. This will restore the registry. The next command to repair the system files is: SFC /scannow
    and press Enter, this may take a while (up to 1 hour) and will end with Repaired corrupted files. Run SFC again till you see "Found no integrity violations"

    Next step is go back to Advanced options and click on Startup Settings, F4 or 4 will boot to Safe Mode that you tried before and you can open Device Manager to uninstall drivers with yellow exclamation marks or Unknown Devices. Shut down, remove the USB flash drive and try to boot to windows. If you get back in a Repair loop you either have a hardware problem (Disk or RAM module) or you need to boot to Safe mode again with the USB stick and uninstall the display drivers with DDU.

    Thanks for the response, I have gotten into WinRE but the 2 commands don't work for me. The first comes back with the system not finding the path specified, the second coming up with "the windows resource protection could not perform the requested operation". I also couldn't find a "startup options" menu, a photo is attached. What should I do?

    Try this: In the Command Prompt WindowsRE Advanced option type: shutdown /r /o /f /t 00

    How did you get to the Windows Advanced menu you show above, did you use the USB recovery flash drive method or F12/Alt+F10? The USB Recovery drive has the most complete WindowsRE menu, F12 or Alt+F10 WindowsRE menus don't have the Advanced Restart option so you cannot boot to Save Mode that way. Try the USB recovery disk method I described above.

    You may have to do a Clean Install of Windows 10-11 if nothing works.
