If there are still troubles in 64-bit (like you still cant install UEFI mode) then we can give further advices, but the first step is a 64-bit reinstall.
I did install the 64 bit LM as indicated in my previous post.
I suppose that the problem is that you installed 64-bit Mint, but you installed it CSM-mode (Legacy). The next command tells
Code: Select all
[ -d /sys/firmware/efi ] && echo "UEFI mode active" || echo "Legacy mode active"
If so, you need to convert Legacy installation to UEFI.
