This question says that it's possible to install Chrome OS as a desktop environment to Ubuntu but it's only available for 64bit PCs. Would it work on my 32bit PC? I just want to try it. It doesn't need to be perfect. What are the limitations of such an installation?
first install 64-bit ubuntu, 32-bit or not

Google-chrome which is needed to run this build of chromium os must share some features, including sandbox(a hunch). Open Nautilus using sudo power. Browse to filesystem to /opt , there are two folders of our concern chromeos and google. Open google in new tab copy all the contents of /opt/google/chrome folder and paste into /opt/chromeos. nautilus will give you the folder and file conflict notification. MERGE FOLDER BUT SKIP FILES.It will only copy missing files. Now you have chrome-sandbox in chromeos. Now exit and remove the line "--disable-setuid-sandbox /" in chromeos file located in usr/sbin/chromeos if you have edited before. Delete Chrome-os folder in home and start a fresh copy typing chromeos in terminal.
