Hey Todd... check your secure boot option in the bios... I think it will be in the Security or Security Chip or TPM menu in the thinkpad
if that is enabled it will only load a recognised image at boot time... just temporarily disable secure boot Be careful dont disable the TPM completely if you have an encrypted disk with another OS on your Laptop or you will lose the data if you dont have the Key (that could be stored in the the TPM) backed up... but the secure boot mode can be adjusted safely... and that is probably what is catching you out at the minute All the Best, Tom Smyth On Mon, 12 Oct 2020 at 01:12, Todd Brewster <toddbrewste...@icloud.com> wrote: -- Kindest regards, Tom Smyth.
