So earlier today, I tried setting up my OpSec by installing Tails OS on my PC. The software required 2 flash drives as the OS would be booted from an external storage. I copied the files using a UUI software, switched my secure boot off, enabled legacy mode and UEFI but still couldn't get it to install.

First of all, you should know that both drives are required to have at least a combined free space of 4GB and have to be formatted before use. I formatted the drives to FAT32 only to get an error that the software requires Fat32, is there really a difference?

Secondly, I tried formatting to NTFS but this also resulted in another error.

Do flash drives differ from one another? If yes, which ones can I get to have a successful NTFS format.

The whole thing ended up in some GRUB screen I just don't understand.
