Thanks, however, I probably did something stupid since it didn't work for me. I went into BIOS: F10 > BIOS Setup > Advanced > Secure Boot Configuration - here I changed "Legacy Support Enable and Secure Boot Disable" to "Legacy Support Disable and Secure Boot Disable". When I then try to boot the system I get "BootDevice Not Found. Please install an operating system on your hard disk. Hard Disk - (3F0)". If I try to boot the system from a USB memory to install Linux again I cannot do it since if I press F9 for boot menu it is just blank. It suggest a hard disk check and the quick test shows no errors. When I switch back to "Legacy Support Enable and Secure Boot Disable" the installed system boots Linux as before (with the same graphics problem as before of course). Any idea what I am doing wrong?
