I have used an external SSD (Samsung T5 500GB) to install EOS.
For the installation I used a Dell Laptop (precision 3500), and now I want to boot EOS from my main machine, but once I get into the boot menu, the only options I have are:
Windows Boot Manager(Main SSD)
Windows Boot Manager(External SSD)
I am not sure why this is happening (when I boot EOS from the external SSD, using the laptop everything works fine).
My main machine build is:
Ryzen 9 9700
Gigabyte B650 Aorus Elite AX
If that matters, there is a virtualization option in bios, which I have already activated.
This isn’t that difficult. I have in the past had a Linux on an external drive that I swapped between a couple of computers. However there are a couple of things you point out that are things the OP will have to address and that is legacy/efi boot and gpu. If he is already efi boot and non of the video cards are Nvidia it should be fairly simple.
My idea was to try to do a clean re-install from the USB with the ISO installer while using my main machine ( I don’t really know if that would make any difference !? ).
I am getting the following error while trying to boot from the USB:
