Hi, I'm trying to install the XFCE version onto a USB. I keep getting the following error in the last stages, I'm also showing the partitions I manually setup since it initially set up a single partition. I'm using uefi.
The error message is telling you that you can’t combine a GPT partition layout with BIOS boot mode without an additional partition for BIOS boot support.
The better options are:
Boot in UEFI mode if you want to use GPT.
Use an MBR partition table if you want to boot in BIOS/legacy mode.
