I used to have debian on my laptop. Then I removed the old hard drive (with the debian OS on it), and put it in a USB external hard drive box. And installed a new SSD hard drive into the laptop, installed windows 10 on it.
Now I am trying to boot into the debian system on my USB external hard drive when I connect it to my laptop and set the USB external hard drive as the top priority boot device in BIOS. The BIOS however cannot seem to detect the debian system on the external hard drive.
Is there way for this to work? Do you need more information to help me? Thanks!
