I installed a multiboot iso on the second partition of my flash drive. However, whenever I startup my PC, I never get prompted to boot from USB. It doesn't show up when I go into BIOS and manually choose a drive to boot off of.
Is there a reason for this? And how can I fix it. It seems like there is a /boot/grub/x86_64-efi folder on my flash drive at least so I don't know why this is all happening.
Thank you.
