I installed Ubuntu 22.10 in an USB flash drive and it boots perfectly fine. Then I cloned this drive to an SSD on Windows using MiniTool Partition Wizard. This SSD is connected to the computer using an USB-to-SATA adapter.
The problem is that this USB SSD doesn’t appear as an option in the boot menu in one computer. In this computer the USB flash drive boots fine, but not the cloned SSD.
I tried in another computer and both drives boot fine, so clearly the drives are OK. The fact that the first computer can boot from the USB flash drive but not from the USB SSD is puzzling.
Do you have any idea what may be going on? Thanks.
