CatK is currently NOT compatible with UEFI based systems. What does this mean?
This means that if you run this on any modern laptop, or any PC under EFI mode, it Will not boot!
On most modern desktop PCs, you can select "BOOT > Boot mode" To change it from UEFI to LEGACY/UEFI. Unless you are on Laptop computers, as you cannot change it to BIOS/Legacy.
