Error: BIOS/Legacy Boot of UEFI-Only Media

  • The drive can boot in UEFI mode only. It will not boot in BIOS/Legacy mode.

To remove this message you need to do one of the following:

  1. If your computer supports UEFI, go to your UEFI settings and lower or disable the priority of CSM/Legacy mode.
  2. Or Recreate the drive in MBR partition scheme where target system is BIOS (…….)
  3. Or Recreate the disk with Boot type: Non bootable

My suggestion the number 2 option.
