How to resolve this error? This is the first time I have downloaded Garuda Linux (based on Arch Linux). I have downloaded it from SourceForge redirected from the official page Garuda Linux Download. I have downloaded the Dragonized Gaming version. This is the first time I am booting this and I don't know what went wrong.
After following @Michael Dorst's solution, I get the following error

I have allocated 53 GiB but I don't know why it says that the partition is full.
