Hi Evert,
Yes, I’ve tried that. The problem is that the four partitions, including the MBR, have all been wiped. I have tried installing Windows 10 first but it won’t allow me to select any of the formatted partitions (due to GPT issues). I have since tried to use Gparted to partition and format everything appropriately to allow for a regular install of Win 10, but I can’t even get it to load using YUMI or Tux. The laptop just prompts me to restart when I try to boot from the USB when using Gparted. Is there any other partitioning tool, paid or otherwise, that I could use via USB to format and partition these drives?
