Error creating chromeos.img

hayrun-st commented 2 years ago

Using Windows 10 WSL, Ubuntu image to create chromeos.img

I'm seeing lots of errors when building. I did write the image to USB using Rufus and could not get it to boot on my Dell Latitude 5290 2-in-1.

same issue here

sebanc commented 2 years ago

Install WSL2, I will add an error message in the next release

hayrun-st commented 2 years ago

That worked for me!

koushiksarker2001 commented 2 years ago

worked for me. I have another question @sebanc . I have enabled the configuration of mount HDD on chrome os. Will it cause high CPU usage everytime i boot into chromeos?

i was trying to create chromeos.img using a chromebook with the linux env and getting same error, it is possible to use a chromebook to create the img or im wasting my time?

same issue , trying create image using chrome os flex

I had a same issue when installing ChromeOS to Surface3(not pro) with Rufus using Linux Mint.

$(( $size * 512 )) in chromeos-install.sh is invalid syntax I guess.

So I change as follow.

step 1. I added following lines.

local pv_size
pv_size=$(( size * 512))

step 2. And change as follows

$(( $size * 512 )) -> $pv_size

There are 2 points to add about step 1 and 4 points to change about step 2.

This is chromeos-install.sh of r111 I used to install without error message. Give it a try. Good luck.

if [ $(whoami) != "root" ]; then echo "Please run with this script with sudo"; exit 1; fi

im on chrome os apparently works by tty2 but with developer mode on and package manager called chromebrew

i needed to go to tty2 and use chromebrew install pv

then it works

i believe crostini is not viable way because i cant get the "loop" module to start via modprobe

people running from chrome os should try running bash script in tty2 first
