How can i install raspberry pi os (or any linux thing like ubuntu) on my old chromebook?

I have an old Acer Chromebook 11 (C730), but when i try to follow instructions like on this page it will say something about noexec and i dont know what to do. i already took the wp screw out, but i dont know what to do next.

PS i tried to install an older version of chromium os that didnt work…

rather than tell us ‘it will say something about xyz’, tell us “I ran command abc and the output was def”, because we can’t help with half-assed summaries of an error from unknown input.

any message about ‘noexec’ when running a command is a warning, not an error, and can be ignored.

When i run cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh it says this weird error about noexec and it quits

I googled it and it says that noexec means i cant run it

Kind of fixed it now but giving the error:

curl: (6) Could not resolve host: mrchromebox.tech

The instructions i was trying to follow was How to install Windows 10/11 on a Chromebook

this site has extensive documentation, and you’ve come here for help, but using some random instructions elsewhere? SMH

no, it doesn’t. It gives a WARNING. It’s not preventing you from running the script. And as I stated above, you telling us “it gives a weird error” doesn’t help us help you.

kind of fixed? what did you do exactly? Couldn’t resolve host is a DNS/internet connection issue…

Okay. I now got into the chromeos device filmware utility script, but when i press 1, press enter it says this:

The RW_LEGACY filmware update is not supported for devices which have reached end-of-life

Press enter to return to the main menu

What should i do?

Btw I don’t think u should install Raspberry Pi OS as that is made specifically for Raspberry Pis and Chromebook != Raspberry Pi. There are plently of lightweight Linux distros that are made for old laptops that will probably be better than Raspberry Pi OS.

1 is not the only option. You are unable to install RW_LEGACY firmware, but you are able to install full ROM firmware (option 2).

Since you don’t seem to know the difference between the two (yet), please do read https://docs.mrchromebox.tech

It tells you everything you need to know about this process.
