We successfully followed the method (1) from the website below with no problems. It took around 1 hour and 50 minutes to flash the image for an 85 GB partition. Overall, the entire process, including downloading the files and entering ChromeOS, took about 4 hours. Our internet connection was slow, with a download speed of 1.2 mbps, and we were using a slow HDD laptop. Despite this, ChromeOS performed well. However, there was some lag in PlayStore and GoogleTV, likely because of the slow internet and laptop.
