lubuntu not installing

[tea for one]

Lubuntu 24.04 will run comfortably on a 32GB eMMC disk
A USB made using Rufus will work
A laptop from 2020 will definitely be UEFI
Do we assume that you wish to replace Windows 10 with Lubuntu 24.04?

i downloaded the iso from official site (check previous post)

It is not the iso on the site that would be the problem but the process of downloading it from its location to your computer that can cause corruption.
