How to create USB Bootdisk from installed Linux Mint
 

I created a Linux Mint 21.1 USB Bootdisk. Installed on a MacBook Pro 2018. I want to update to Mint 21.3. Then create a USB Bootdisk Linux Mint 21.3 from the installed system.
What Option do I use in Linux?

(English speaking and native language is Dutch ;-)

I suggest to use Virtualbox inside MacBook Pro

and install Linux Mint on it

or check out this link: https://www.macworld.com/article/668...e-for-mac.html

Did you check the Mint site at the link below as it explains creating a bootable usb while using Mint or various other operating systems. Did you try this and have problems and if so, what were they?

Thanx Yancek.
I knew the info. I thought there was a direct way to do it quickly from Linux (without an ISO file) but found out there probbly isn´t. I remember from "ẗhe old days" with MS DOS it was possible to create a bootdisk without ISO file.

You can create a boot disk with Linux using Grub or Grub2 but you will manually need to create a menu.lst(GRub Legacy) or grub.cfg (Grub2) file. What are you wanting to boot? A boot disk is useless without an operating system to boot and the old dos boot floppies were very limited. Not really sure what you are trying to do and what you have when referring to the different Linux Mint and then the Mac?

There are a few tools for this, but I am not sure what kind of result you are looking for.

Have you considered pengiuneggs?
