I have just installed Solus to my USB drive, but it seems that it will only boot from one computer. In the installation, I chose to install the boot loader to an extra m.2 SSD I had ( thankfully, it was empty ). Well, actually, I had 2 USB drives - one with the Solus ISO to boot from and to install from, and another empty one to install to. I think this has to do with the boot loader. In other operating systems, this was not a problem. I have another USB drive with pop_os! installed on it, and it works on both computers. In the install menu, where it says a drive to install the boot loader in, only my internal hard drives show up. Can anyone help? Thanks!
