I used AOMEI Partition Assistant Standard Edition 6.0 to create a Windows To Go hard drive (MBR, 4 partitions, Toshiba USB 3.0 v73600-H 2TB)
I am able to boot to my hard drive, but only in legacy BIOS mode. when I put my PC in legacy BIOS mode, I can boot to the Windows To Go hard drive just fine, but then my PC won't boot to the internal hard drive. I want to convert the Windows To Go drive to UEFI, otherwise, I won't be able to use it on other PCs without modifying the settings, which completely eliminates the point. Is there any way to make my external hard drive or Windows To Go support UEFI?
UPDATE: I previously used GPT and it did not work. I will convert if necessary, but you have to tell me what to do after that point.
