I did this with a live USB(downloaded Rufus and Ubuntu 20.4 iso from their official website) and everything went smooth during the whole installation process. It came with Free DOS and I've tried to install Ubuntu on it. Today I received my laptop, an Acer Aspire 5 (A515-44G-R9YM - with the Ryzen 7 4700U one). Sorry to bother, I hope everything is fine.
