How should I make my partitions for a Full Install USB?

Creating a Full install Ubuntu USB from a Pre-built Image File that Boots BIOS and UEFI

• Download Image File: https://phillw.net/isos/linux-tools/uefi-n-bios/dd_unb_ubuntu-20.04_15GB_2020-06-26.img.xz

• Download Rufus: https://github.com/pbatard/rufus/releases/download/v3.11/rufus-3.11.exe

• Double click Rufus exe file. (No need to install it).

• Select USB Target drive in Rufus.

• Select above Image File in Rufus.

• Click Rufus start button.

• Wait for flashing to complete... Done.

• Open GParted and adjust partition sizes, create a FAT32 or NTFS data partition in the empty space if wanted.

(Password is "changeme", change it),

The SSD should boot on almost any modern X64 computer.

Thanks to sudodus for the image file.

In Windows it may be necessary to install 7Zip before proceeding. Rufus will use it when working with the .xz image: https://www.7-zip.org/a/7z1900-x64.exe
