I have Ubuntu 16.10 installed on my hard drive and Windows 8.1 on my USB. When it is plugged in, I normally go to BIOS each time to edit startup order in order to load the one I want.
Is there a way to use GRUB to choose between OS's on my USB and Ubuntu? (I already made it so GRUB always loads on startup.)
I have looked at other questions and none worked.
