partitioned Bootable USB

[kp33]

As my member status indicates I'm a newb, so this might be a rather simple question. I use a 500gb external hard drive for school files, games, and other things. I was wondering if I could partition the drive into a few OS Bootable drives. Such as setting 450gb partition for my files then like 9x 5gb partions for various OSs (ubunutu, mint 32 bit, fedora, tails, ect). Once partitioned would I be able to format individual partitions?

Why would you do this? And I believe you can only do that with GPT.

Yes you could but you would need to be handy with GRUB loader.

Yes, you could if you first partitioned it in EaseUS partition manager, and then when making a bootable USB, you select the partition that you made

The reasons I'm wanting to do this is because (in regards to ubunutu and mint) I work on several computers that are very outdated or for older people and I use these OSs, I'd prefer not to carrier around several drives or disk. I also use tails and Dereks Boot and nuke. Also...why not? Thank y'all
