Setup Dual Boot Linux And Remix OS With GRUB Customizer
Open Terminal and input the below commands. You need to be superuser to use below commands. Superuser access can be acquired by typing “su” or “sudo” in most distros. You need to enter your password which will remain invisible. This is normal.
Now, you need to extract the Remix OS zip file you downloaded from above link I’ve provided. You will find Remix OS.iso file here, Extract the .iso file in a separate folder. Now open the file manager with root access.Copy the four files i.e. initrd.img, kernel, ramdisk.img, and system.sfs to remix folder you created in above step. The folder should be located in the root of the system. Open your file system root level and you will find it.
Now open GRUB customizer. Find the default entry here through which your current OS boots. It is generally named with your OS name and is located at the top.Select it and hit the edit option on top pane.
Now copy the whole entry and quit the dialog box. Now in the top pane select the option to create a new entry.
Name it as Remix-OS and in type, select other.
Now in the boot sequence space paste the entry you just copied.
Find the two lines that indicate the location of vmlinuz and initrd. They are usually located at the bottom and start with Linux and initrd.
It will look something like this now. Remember incase you are using a 32 bit version use below entry.
linux /remix/kernel root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive CMDLINE
You have successfully completed the guide. Now reboot the PC and when GRUB menu appears select the Remix OS option and wait. First boot will take much longer time for about 15-20 min. That’s normal.
