when I try booting from the usb stick it indeed shows two boot options,
'Patriot Memory PMAP' and 'UEFI: Patriot Memory PMAP' but when I try
picking the UEFI option it fails with message
error: file '/boot' not found
Is this a GRUB error ? Does it fallback to a grub rescue prompt ? If
yes, what do the 'set' and 'ls' commands display ?
however, if I boot from this stick in non UEFI mode I see that it has two
partitions, and both of them have /boot directory.
Any idea what could be wrong? Some search suggests that it could be due to
the fact that I copied the .iso image to the stick using dd, is this the
case?
What ISO image is it ?
dd to /dev/sdX is the proper way to write the image if it is a
ISO-hybrid image.
Instead of using an ISO image on the stick, you could also create a DOS
or GPT partition table, an EFI partition (FAT) and a Linux partition
(ext2 or ext4), mount the EFI partition on /boot/efi and the Linux
partition on /boot/grub and run
grub-install --removable
update-grub
Then reboot and select the USB stick for boot in UEFI mode.
