I attempted yesterday to install Debian on an external HDD. Created my partition on the external drive, booted from CD, set up file structure during graphical install on the desired partition of said external. I completed the install, then following the restart my computer said my USB drive had no bootable partition. So, I restarted again, unplugged my external, and went to boot into windows only to have it tell me BOOTMGR not present. (Got that fixed though)
So my question is, is this even possible? To create a bootable Linux from an external HDD that is partitioned. Or did I just botch a step.
