Hi!

can I drop 2 complete installers (Big Sur and Mojave) on the same bootable USB-stick?

that is, can I actually boot into the selected installer?

thanks!

FWiW, the previous reply is incorrect. You can partition a sufficiently large flash drive and create separate bootable installers on each partition then boot to the one you choose. I have one with Catalina and Big Sur installed.

In the Context of " . . . . same bootable usb-stick ? " - splitting / partitioning the drive into two or more partitions becomes more than one drive. Yes, doing so will allow creating two or more Bootable Installer.

Also incorrect. It's one drive with more than one partition.

No. The How to create a bootable installer for macOS will claim the Entire Drive

To do two separate Installer on One Physical Drive - Partition first - then Yes. If not partitioned - can not do.

Parse words - the OS, whatever version, will see two drives

Just to add, you need a minimum of a 32GB flash drive.
