Installing system on USB flash drive

I think this is a cool idea.
But failed
Unable to boot the system in the USB flash drive.:scream::scream::scream:
I can install Haiku directly in my computer.
My computer is intel processor and nvidia graphics card.
When I installed Haiku on the USB flash drive, I thought it would be successful, because I have seen many people install linux and WinToGo on the USB flash drive.
It is possible in theory, but it is a failure in reality.:joy:

what is the error information?

You have possibly made a mistake somewhere, make sure you have created the EFI/ESP partition and copied the efi files manually if you are using a UEFI based system.

My computer is at home. I’ll check it again when I get home.

This should be possible.
