I want to install stock Android x86. And i have GNU GRUB already installed. what will happen to that?

[Scripter Provider]

I have installed PrimeOS standard on my pc, which includes GNU GRUB for dual boot. I want to install stock Android x86. If i select to install GRUB too, what will happen to the existing GRUB? WIll it remove/overwrite its configuration and just have an option to boot to Windows and Android only? Because i want mutipule Android OS just in case something goes wrong with the other one, or just for fun. So yeah hopefully the communtiy will help me with this, because i want to install Bliss OS.

It will overwrite existing grub, you have to skip grub instalation and configure menu.lst manually.

I have taken a different path.  I installed Android-x86 inside a VirtualBox.org virtual machine.  That laptop is a Windows 8.1.  It works just fine.  I have a Google account that allows me to do a data-backup of the Android-x86 setup.  Since I'm using Chrome & Youtube as well all my tabs, history, and other apps data are synchronized as well.  A  full backup of the Windows laptop captures all of that as well.

It runs as a window on Windows' Desktop.  It did take some time to adjust to the goofy relationship between the Desktop mouse vs the Android mouse behaviors.  I did get it after many trials.  That is also the result of the relationship between the Desktop & the VirtualBox virtual machine too.  

Maybe a few tweaks of Android-x86 & VirtualBox's setup could resolve the mouse transition awkwardness.

It may use grub.cfg file

Anyway you just should search for "(root directory)/grub/menu.lst" or "(root directory)/grub 2/grub.cfg"

They should be under EFI partition, or under partition where is your os installed.

The really good news is that you may learn enough to write your own GRUB setup manually.  Which's exciting.  BTW is this a class assignment.  GRUB can boot any configuration of hypervisors and OSs.  Oher utilities are used in the Cloud.

If Windows is still on the PC with a GRUB then compare that to GRUB 2 Win on SourceForge at 2.06 beta & the changelog from 2021-04-03.

Make a complete disk image useful for a "bare-metal" restore, just in case.

You can also backup just the GRUB folder/directory but that may not be enough.

SourceForge: GRUB4DOS Toolbox for Windows --- Website  I've tested this, it works.

From Unbuntu: Grub2/Installing ...there are many Unbuntu articles on all things

Google Search: GRUB for windows  Ways to use GRUB2Win

Google Search: GRUB reinstall change  many examples

Google Search: bliss OS using GRUB

Google Search: PrimeOS in VirtualBox

It would be useful to know more about the PC's make, model, CPU, available RAM, storage size & free space.  Later things like graphics & display, USBs, etc will be a focus.

OS Virtualization, Wikipedia, was sent to us from heaven.  Actually, it was IBM in 1968, 14 years before IBM PCs.

Just to fill out more alternatives using different OSs, PrimeOS, & Android-x86...

Virtualbox.org has distros for major OSs.  If your PC is less capable there are several minimal LINUX distros that can host VirtualBox

Inside LINUX there are several ways to allocate CPU time to processes.  That's useful to direct CPU time to VirtualBox or multiple OS images as needed.  There are a number of VMs packages out there like VMware's or different Xen distros 

Another arrangement is to boot directly into a hypervisor.  It acts as a VM managing host.  PrimeOS in this design is a "Guest" OS virtual machine & still runs other OSs as Guests as well.

It has been demonstrated that Android-x86 can be run in VirtualBox & connect to Google's Android device infrastructure & services.

This will inform you about GRUB & virtualization alternatives.  Good luck.
