Forgive the rookie question but still fairly new to Linux land. I'm trying to create a "self contained" Ubuntu 20.04 installation on a 64GB USB Stick. Summary Below:

  • All of the bare metal that I will be using has capacity 16gig RAM, My understanding is I don't need the Swap partition?
  • FAT32 Partition? (What size to allocate & why)
  • EXT4 Partition? (What size to allocate & why)
  • I've been trying to install the full Ubuntu 20.04 on the same USB as I'm running Ubuntu Live (demo) without success. I presume this can't be done as it is mounted at the time? i.e you need 2 USB sticks, one with live running (to access G-Parted) the other the target (new full install)?
  • I don't want to see any of the storage media on the host machine when booting from USB (20.04) i.e. OS and storage all contained on the USB. A fully isolated system.

Thanks in advance

Cheers NewB

Partition sizing - Ubuntu 20.04 USB Full Install

Charles Green's recommendation, Easy Full Install USB that Boots both BIOS and UEFI, is a good starting point. It is quick, easy and easily modified.

After flashing the USB you can use GParted from a Live Ubuntu USB to stretch the root partition to about 40GB and fill the remaining space with NTFS or FAT32 data partition. A swapfile is built in.

In answer to your question about installing to the installer Live USB see: Can Ubuntu be installed to the pendrive it was booted from? . The same principle using toram can be used to create the above USB.

If you prefer creating your full install USB from scratch see: How to Create a Full Install of Ubuntu 20.04 to USB Device Step by Step
