   To reiterate and expand on prior comments:   
      
   1. BIOS must be set to legacy boot, sometime hidden as CSM =ON to allow   
   legacy boot   
      
   2. Slackware DVD and USB installers are hybrid. Hit F11 or F12 (depending   
   on motherboard) to get a list of bootable devices.  Choose wisely! You   
   will see 2 entries for the USB stick if the BIOS allows legacy boot and   
   another for UEFI   
   NOTE: If legacy is disabled in BIOS, you will only get the UEFI got option   
   NOTE: Depending on BIOS legacy MBR boot is fallback if no EFI table entry   
   or partition is found.   
      
   3. GPT partition can only be legacy booted via MBR on ONLY /dev/sda.   
   superblock won't work. Use MSDOS partitions, set bootable flag on the   
   root partition, and then load LILO into root superblock.   
   NOTE: GPT does not have partition boot flags   
   NOTE: you will have to erase the MBR on /dev/sda. legacy boot ALWAYS   
   looks there 1st.   
   # dd if=/dev/zero of=/dev/sda bs=446 count=1   
   (bs=512 deletes the partition MBR+partition table)   
      
      
   Have fun!
