In this tutorial, I will show you how to install rlxos from any other Linux which is already installed into your system.

Prerequisites

• PC with Linux installed (no any WSL shit)
• Latest rlxos ISO Here
• An Empty Partition of size at least 5GiB

Preparing Partition

We need to have 2 directories in the empty partition where we paste our root filesystem image and kernel file.

Steps

• Extract the ISO

We only require 3 files from the ISO

• rootfs.img
• boot/vmlinuz

• boot/initrd

• Copy rootfs.img into rlxos/system and rename it with version mentioned on the ISO.

• Now copy vmlinuz, initrd to boot (boot directory of our empty partition)

• Installation is completed from the rlxos side, now we need to do some hacks so that os-prober of your installed Linux system will able to detect the rlxos partition.
  • Create a directory lib in empty partition.
  • Create a empty file ld-linux.so in that directory

and your final directory hierarchy should look like this

rlxos will not use this ld-linux library but the one which is present inside the system image, so don't worry.

• Now update the grub configurations

  sudo update-grub
  

and make sure either rlxos or (some unknown Linux distro) get detected by os-prober

And a last Complication Step Now one Important thing, you need to add a flag system= (where is release version of rlxos) inside the menuentry of rlxos in /boot/grub/grub.cfg of your installed system

or add the flag from the grub menu during the boot, for that follow the below steps

• Reboot the system and press E on rlxos entry.

• And add the flags to make it look like this.

Last Second line,

linux /boot/vmlinuz root=/dev/sd?? system=2106

• Press 'ctrl-x' or F10 to start rlxos.

Enjoy!
