How to boot linux partitions on external USB HDD

[adamjr]

I am trying to boot my external USB HDD, but I tried Plop Boot Manager and PlopKexec and both seem to detect the device but not find the partitions?
The error message is "No HD", (both EHCI and UHCI)
When I put the HDD inside the laptop instead of in the USB case I can still use it.
I can read all the data on the USB HDD with debian (I didn't try mounting the device with the Plop live, should I do that?)
Thanks for writing by the way.  Your work is a positive contribution to the world.

Numbers 1 and 3 are linux root partitions:

I assume, its a standard hard disk installation and not a live installation on your USB hard disk.

Plop Boot Manager: The problem is, that your computer seems to use an internal USB hub, witch is not supported by the 5.x release.

Plopkexec: I assume, you use grub2 as boot manager on the USB drive. grub2 config files are not well supported by plopkexec. You should create a custom plopkexec.cfg file with kernel and initrd configuration in syslinux format.

Great! Fixed.
I connected to a USB port that was not on a hub and it worked! (using Plop boot manager).
Thanks Elmar!
