I'd suggest trying to follow the Lubuntu manual

The chapter you want is 1.3 Installing Lubuntu

Note: I've used stable in the provided URLs, if you were wanting to read the LTS manual the word stable would have been replaced with lts which currently shows the Lubuntu 20.04 LTS manual; stable refers to the 21.04 manual.

If you have questions following the Lubuntu documentation, then you can ask here, or using Lubuntu's other support options including their discourse/forum.

You can install with swap with Lubuntu 21.04, but for more details I'll provide https://discourse.lubuntu.me/t/swap-and-lubuntu-21-04-hirsute-and-up/2591

  • FYI: Lubuntu 21.04 (even impish) was tested on devices with as little RAM as 2GB, but on my laptop with only 2GB of RAM, I'd increase the size of the swap that is provided by calamares by default (it currently only sets up or doesn't use swap; giving you no control on swapfile size). You can use swap partition using Manual Partitioning if you prefer swap partition.

seeing that you wont to replace every thing when you are manual partitioning click "new partition table" and select gpt not mbr then press next.
