After reading on old blog-post I re-learned how to make a Windows XP usb boot disk. (download Windows XP, use RUFUS and make a USB stick). Windows XP is modern enough to work similar as modern installation, but old enough to run the cool old nostalgic games

I followed the staps as provided on this page: https://answers.microsoft.com/en-us/windows/forum/all/windows-xp-recovery-commands/881e8f9d-b24e-438d-bd78-f632e3dba0b2

But since it's old; I will copy the steps here:

Please find below the list of commands in order to boot from the recovery drive:

Boot from a standard Windows XP Install CD (not a Network Install CD).
At the first setup screen, hit R to repair Windows using the Recovery Console.
Select the Windows installation that you would like to repair by entering its number, followed by Enter.
At the Recovery Console, type each following commands followed by Enter:
    CD..
    ATTRIB -H C:\\boot.ini
    ATTRIB -S C:\\boot.ini
    ATTRIB -R C:\\boot.ini
    del boot.ini
    BOOTCFG /Rebuild
        Set the Load Identifier to: Microsoft Windows XP Professional
        Set the OS Load Options to: /noexecute=optin /fastdetect 
    CHKDSK /R
    FIXBOOT 
Type exit to reboot the computer.

This will rebuild the OS back for you.

Everything go's relatively fast, but the CHKDSK command takes time.. A lot of time...
