I recently installed ubuntu 22.10 on a SSD to use a secondary OS for my laptop (I usually run it with windows). My intention was to connect the SSD using a USB cable and boot it from BIOS or using advanced restart (shift + reset) but its not showing up as bootable (UEFI) device from any of those places.
If I connect the SSD to my laptop it autodetects the ubuntu installation and boots it as the primary drive (which make no sense for me, since it is not detected as a bootable device when I look into it). I would like to be able to detect the disk from the bios since I will also be using it on my desktop too (I also tried to check if it was detected on my desktop without any luck).
I've checked the ubuntu installation and made sure to have an EFI partition (just to make sure that I didnt install the ubuntu as a Legacy drive (not really sure how this work)). Also tried reinstalling 22.04 and faced the same issue. Does any one have an idea why the ubuntu installation is not display as a bootable device on the BIOS? The pendrive I used to install it, its detected properly btw.
Thanks for your help!
