Most of those are system kexts.
If you had them on your system drive then you may be ok without any on the USB.

Look on your backup disk for /EFI-Backups, in there you may find a copy of your config.plist.
If you have /EFI-Backups then you will have a complete copy of your /EFI folder there, you can just copy that to the EFI partition of the USB.

After power on press your boot menu key (usually f12 but YMMV) then select the EFI partition of the USB.

No more ideas.
Restore your backup.

This is the very reason that we make backups.
There really is very little point in backing up if you have no means to restore.
What were you planning to do if a hard drive failed ?

I extra did 2 full system backups before changing the files. I just wanted to update to Catalina and as in the guide explained i made one with carboncopycloner and an extra one with timemachine for safte if that helps?
