I dual-booted windows 10 with ubuntu 20.04 but now I can't boot from USB/CD.
I am trying to boot from Windows To Go USB [pen drive] but the USB option isn't in either menu?

maybe your pen drive is not working correctly

try using a different operating system to boot from it like a created USB pen drive with microsoft´s media creation tool

try a different USB port

try a different USB pen drive
