ChromeOS Flex lets you rejuvenate your old computer by replacing Windows or MacOS. It is a lightweight modern operating system from Google designed to run nearly any computer. And it is suitable for business and education purposes. Like any OS, to install the ChromeOS Flex, you need to create its bootable USB drive, which will consume around 12GB of storage space on the USB.

After installing ChromeOS Flex on your computer, you may want to format your bootable USB drive to use it for other purposes. However, you cannot restore the 12GB storage space without formatting the ChromeOS Flex bootable USB. Windows cannot directly format the ChromeOS Flex bootable USB, but an alternate method is available.

ChromeOS Flex is a lightweight OS, and the minimum requirements to install this OS are 64-bit Intel or AMD CPU and 4GB RAM. Unfortunately, you cannot use ChromeOS Flex on every old computer. Since the OS requires an active internet connection, you cannot use it on most computers because ChromeOS Flex does not support many old Wi-Fi adapters or dongles.

So, before installing ChromeOS Flex on your old computer, select the Try It First option to test whether the OS detects your Wi-Fi. If not, drop it at present. In the future, Google may add more Wi-Fi adapters or dongle support to ChromeOS Flex.
