Can't install OS on Lenovo IP Flex 5

Hi all, following the tutorial on installing Linux on my Chromebook but every OS I’ve tried has failed to install. I’ve tried just about every distro recommended on the Chrultrabook docs, but none of them are able to finish installing. The process will run for a few minutes, but then get stuck. I’ve tried using various installation media (a few different USB sticks as well as a couple micro SD cards) and that has no effect. I also am unable to boot from the installation media. Any ideas of what I can try? Thanks!

I also am unable to boot from the installation media

Can you explain what exactly happens? You said that “none of them are able to finish installing”, which means that you were able to start the installer. But how did you even start the installer if you can’t boot from the installation media?

any updates? i have the same laptop and want to know how simple, secure, and realiable it would be to install Linux on it. i have zero technical experience

When you are in the installer can you plug in a drive and install it like that or not
