With the above said, there is another issue that has been vexing me, I have an external USB harddisk and when it is attached the computer fails to boot the OS (CentOS 7.8.2003). After the Lenovo logo all I see is a blinking underscore on the screen. Disconnecting the harddisk at this time has no effect. I have to have the harddisk disconnected when I boot and then connect it, after which it works fine. The only noteworthy thing I am aware of is that is encrypted using LUKS so I have to enter a passphrase once it is connected.
