How to Boot Ubuntu toRAM, recently updated to support modern versions: In this tutorial, we explain how to boot Ubuntu entirely from system memory using the toram boot parameter. This allows you to copy the entire Ubuntu live environment to RAM, and once it's loaded, you can remove the USB device and continue running Ubuntu from RAM on your computer.

While this feature was initially broken in older Ubuntu versions, modern distributions (and derivatives) now support the toram boot parameter by default. This makes it easier than ever to run Ubuntu entirely from RAM.

What's New in Booting Ubuntu toRAM

In recent Ubuntu releases, you can simply append the toram boot option at startup without needing complicated manual steps. This tutorial reflects the streamlined method for booting Ubuntu to RAM with modern Ubuntu versions.

Prerequisites for Running Ubuntu from RAM

Ubuntu Live CD or USB: Ensure you have the latest Ubuntu live environment.
USB storage device (optional): Required if you want to store the live environment on a USB drive. Make sure you have at least 3–4 GB of space.
Minimum System Requirements: A system with at least 4 GB of RAM to hold the entire Ubuntu live environment. Larger environments may require more RAM.

How to Boot Ubuntu to RAM

Insert your Ubuntu Live USB and Boot Up: Start your system using the Ubuntu Live USB drive.
Press F6 or E to Access Boot Options: Once the Ubuntu boot menu appears, press F6 or E to access additional boot options.
Append the toram Parameter: At the boot options screen, find the Linux line ending with quiet splash and append toram. It should look like:
```
linux /casper/vmlinuz file=/cdrom... quiet splash toram
```
Boot Ubuntu into System Memory: Press Enter or F10 to boot. Ubuntu will load the entire live environment into RAM. Once loaded, you can remove the USB and continue running Ubuntu from system memory.

Important Notes

Persistent Storage: Modern Ubuntu distributions allow you to choose between toram and persistent storage. You cannot use both at the same time, but they can be configured separately on different USB drives or partitions.
RAM Requirements: Ensure your system has enough RAM to hold the Ubuntu environment. Most cases require 8 GB, but larger environments may need more.
