I'm looking to keep a flash drive with a ton of ISO files that I can use to live boot any of the operating systems available on the drive, I used E2B and it worked for my other computers but not the one device I needed it to work on (typical). I made sure to switch UEFI to Legacy in my bios, but to no avail it would make it past bios and then sit at a black screen for eternity (instead of the menu screen) I then tried just a USB burnt with a Kali distribution, this is the other main OS I need to have available for my cyber security course, but not even that would go further than a black screen.
