Can't install Windows 10: how to convert hard disk from MBR to GPT (don't have another pc the hard disk fits in)


New Member
So I bought a second hand laptop without hard disk. Had 2 old ones lying around that fit, but can't install Windows on it (it's already on a USB stick). At least one hard disk needs to be converted from MBR to GPT. But the hard disks don't fit into my old laptop, so how can I convert them? Is something possible from a USB stick and with only BIOS access?
