I have a couple flash drives on a keyring that go everywhere with me - one for PC/Windows/Linux which runs software called "Easy2Boot" which basically gives you a boot menu to choose from a variety of installers and repair tools - one flash drive can install Windows XP/7/8/10, a handful of Linux distros, and a bunch of hard drive/partition/recovery tools. After setting up a USB stick with E2B it's as simple as dumping ISO files into the drive, which then come up in the list.

I do the same for Mac - one flash drive has installers for every version of macOS from 10.11.x to 11.4, which can be used for recovery or installation. Basically I just created multiple partitions and created install media on each partition.

I wish these tools didn't have to come in handy as much as they do, but I'm certainly glad I have them!
