I want to make a usb stick bootable with multiple iso files. How can I do it via Gnome disk utility? How can I config the usb for showing grub2 before starting any of ISOs?

Make a Full Bootable USB Stick with Gnome-Disk Utility

To create a bootable Live Linux USB using Gnome-Disks:

  • Open Disks.

  • Plug in Target drive.

  • Select Target drive in left hand column.

  • Select the three lines or dots on the upper right of the window.

  • Click Restore Disk Image.

  • Select the Linux ISO as Image to Restore.

  • Follow the instructions.

If your intentions are to make a Full Install bootable USB:

Both methods should start with a grub menu when booting in UEFI mode. or with BIOS or UEFI in 20.10 and later.

  • Thank you! I want to have more than 1 ISO files in the USB but when I click "Restore Disk Image", it replaces with the ISO I add before instead of adding. – Reza Hosseinzadeh May 04 '21 at 15:53

    The method I prefer to boot multiple ISO's on a drive is shown here: https://askubuntu.com/questions/1269462/bios-uefi-template-image-for-booting-iso-files. This can also be done by creating your own boot partitions as shown as part of: https://askubuntu.com/questions/1217832/how-to-create-a-full-install-of-ubuntu-20-04-to-usb-device-step-by-step (See Note 1). This procedure can be a little confusing. – C.S.Cameron May 05 '21 at 01:25

    More on booting ISO's see: https://askubuntu.com/questions/1269462/bios-uefi-template-image-for-booting-iso-files. You can make your own boot partitions and install GRUB as in the above link if you do not want to use an image. – C.S.Cameron May 06 '21 at 02:15
