    If you format the Windows partition, there will not be Windows.old.
    Back up personal files beforehand.

    Windows.old is normally automatically deleted 10 days after an upgrade.

    If you need to recover files from an unbootable installation, there are 2 basic ways:

    a. Create a live boot disk using another PC, and then boot your PC from that- you can then explore your internal disk content.
    b. Remove that disk from your laptop, put it in a caddy, and connect it to another PC.

    These of course depend on the disk actually functioning.

    How do you avoid catastrophes like this and give yourself a good chance to recover quickly with minimal inconvenience? As has been recommended tirelessly here again and again:

    Routinely and regularly use disk imaging e.g. Macrium Reflect (free/paid) + large enough external storage for image files.

    Given such an image you can restore any imaged partitions and Windows to a new disk or even a new PC.
    Image files also act as a full backup which you can mount to extract files.

    =====================
    Before considering any clean install to that same disk, first check it - else you could be wasting your time. (Think 'house built on sand').

    A clean install means deleting all existing Windows partitions - and thus the data on them.

    ====================

    Failure to boot can be troubleshooted.

    Test the disk drive using a Sea Tools bootable flash drive:

    Many failures to boot files can be recovered by creating a new Windows.old.

    This is accomplished by using a bootable windows 10 iso.

    Find a flash drive that you can format (> or = 8 GB).

    On a working computer create a bootable Windows 10 iso 20H2:

    https://www.microsoft.com/en-us/soft...load/windows10
    Download Windows 10 ISO File
    Create Bootable USB Flash Drive to Install Windows 10


    Perform a custom install:

    One additional option you can use in case is you lack additional computer is to use command prompt during Windows setup.

    Press CTRL + SHIFT + F10 once you pass "select language" option to bring up CMD.

    Attach additional external disk or large enough USB and learn it's drive letter with:

    Code:
    diskpart
    list disk
    exit
    You can then use robocopy command to bulk copy from old system drive to external drive, ex assuming C:\ is old drive and Z:\ is external drive for backup:

    Code:
    mkdir Z:\transfer
    robocopy "C:\Windows.old\Some folder" Z:\transfer\ /EV
    be careful because you need to copy in smaller chunks rather than all at once due to:
    1. memory limitation during setup
    2. file security restriction on old drive

    In case the method that zebal posted does not work you often can use a bootable Ubuntu / Linux flash drive.
    This allows a GUI approach.
    There is no Windows.old with the Ubuntu approach.

    The windows.old is created during a custom install.
    Notepad is not used during a custom install.
    The Windows.old can be restored on any drive.
    See the custom install tutorial.
