I can't get Windows 11 to go through the booting process without indicating an error occurred.

I have an HP Gaming Computer and I installed Windows 11.  I took my old operating system Windows 10 64 bit operating system and grouped it in folders noted as Windows old files.  The computer was operating O.K. until one day after updating drives using the Optbyte Driver Update tool, the computer stalled during the restart of the operating system.  The notification that an error occurred was displayed.  I used a Windows 11 update product loaded on a USB drive.  A registration was given with the product and used to update the operating system registration.  I can start my computer using the old Windows 10 64-bit operating system but not the Windows 11 operating system.  How do I correct this error without buying another copy of the Windows 11 64-bit operating system?

Please read this about Outbyte 

If you were licensed for windows 7,  8 or 10 then there is fee to upgrade to 11 the upgrade is to the same features such as home or pro.

If windows 11 was working fine before your ran that Outbyte then bring up the recovery feature of 11 and find a restore point:  Boot your win11 USB but do not select install, just select the repair option. See method 6 as shown here

but select "system restore" and then find a restore point from the time before you used that outbyte app.

If a problem then post back here as you may need a clean install of 11 or a new (still free) install  into an old backup of your 10.
