In the event that you want to use a distribution that is not prepared for Secure Boot. Of course, keep in mind that the decision to allow deactivating the mode depends on the manufacturers, so it is possible that there are cases and computers in which you cannot do it directly. One factor to consider when choosing a distribution is whether it can work with Windows Secure Boot protection. It is a protection that makes sure that no strange applications are run before Windows starts, and that it can block the launch of some linux distros. Distros such as Ubuntu are already adapted to work with this protection, but if you are going to use another, you should look in its documentation if it is prepared for it. If your computer has a 4th generation Intel processor or later, then you will need to download the latest rammus version from the list. If it’s an older Intel, then lower the rammus. The zork and grunt recoveries, meanwhile, are for the AMD Ryzen 3XXX and the AMD Stoney Ridge. When downloading the recovery, on the right click on the highest number, which will belong to the latest version released.
This is one of the most confusing but important parts of the process, because on the recoveries website you will see that there are a large number of versions, how do you know which one you need? You will see that a code name appears to the left of each recovery, each of which belongs to one or more specific Chromebook models. Here, you will be especially interested in four of the versions, which you will distinguish by their code name, and they belong to Chromebooks with hardware more compatible with normal PCs. Now you have to download a Chrome OS recovery image. In Android, a recovery is the image that all devices have with the essential files of the operating system to recover it in case of a failure, and Chrome OS has it too. Brunch will serve to make this recovery an installable image of the operating system, so now you must enter this website to download the system image. Next, you have to download the Rufus application, since it is the one that we will use to mount the GNU / Linux system on the USB. Just go to the Rufus.ie website and download the latest version available.
There are several processes to install Chrome OS on a computer, but we are going to try one that has already been tested by the community. It is a delicate process in some points, but we will try to explain it to you step by step so that you do not get lost. You will also need a USB of at least 16 GB capacity, as well as install a GNU / Linux distribution on it. This distro will be necessary to perform the conversion of the official Chrome OS recovery file in order to use it as an operating system image. You will also need other things, but we will provide all the links in due course.
It is quite a complex process for inexperienced users, so I do not recommend doing it on a computer where you work unless you really know what you are doing. To be able to do the process, you will need a series of requirements, such as that your computer has the UEFI firmware, the replacement for the BIOS that you should have on your computer if it is after 2011 or 2012.
We are going to explain how to install Chrome OS together with Windows 10, so that when you turn on your laptop you can choose between using Windows or the Google operating system. And no, we are not going to use one of those GNU / Linux distributions modified to look like Chrome OS, but the original system through one of its recovery files.
