How to make an external HDD multiboot?

Question

System administration

A question from among "and eat a fish and ..."
Is it possible to split an external HDD so that there is a partition for creating a multi-boot with a hornbeam and also a partition for storing simple data (movies, music.)
Something like:
1 partition (up to 16 GB) - images of software with a hornbeam (active)
2 partition - just like a regular HDD.
HDD: Transcend - 1 Tb.

Answer 1

To break an external HDD - it must be frozen. Preferably in liquid nitrogen. After that, you can simply drop it - it will break.
Essentially, you can do it.

Answer 2

A few years ago, booting from the Ubuntu LiveCD, I chose either turning the USB-HDD into a Live HDD, or installing Ubuntu on the HDD, and after that it was possible through the usual BIOS menu, then GRUB booted into Ubuntu from an external hard drive. There were several partitions on the disk, now the partition with Ubuntu is gone, but I didn’t format the disk, the data partitions remained and this disk is still defined as bootable. Now I myself have become interested in this topic in order to download not only Ubuntu.

Answer 3

You can, It's best to start understanding programs like winusb, rufus, and so on.
In fact, it turns out that you will have the status of a bootable hdd. Next, you form what you want from the boot, many articles have been written about this. Any boot managers. And shove your images there.
On sale there is a mobilrek for hdd, which can choose any iso from hard and make a boot disk out of it
