Dual booting on different drives. How to do it properly?

So last time I tried dual booting on different drives things didn't go well. So I'm wondering what the proper way to do it is. Also is it best to give it a separate drive to itself or to partition?

Solution

unplug the windows drive, install linux on 2nd drive, plug windows drive back
set linux as the default boot
run

ujust regenerate-grub

ujust regenerate-grub

ujust regenerate-grub

ujust regenerate-grub to add windows to the grub menu (assuming the windows drive is not bitlocker encrypted, in that case you need to switch using the bios menu)

Is there a way to possibly turn it off via bios? Not that I can't do it manually but I'd rather not if I can avoid it.

Figured it out

bazzite install should allow you to select that whole another drive

BBryan bazzite install should allow you to select that whole another drive

Reece TaylorOP•12/1/24, 4:55 PM

Yeah but you need to disconnect your windows drive to dual boot cuz otherwise it breaks things

Bryan•12/1/24, 4:56 PM

Has it happened? It would mess things up if you did linux first THEN windows but once you already established windows then you are good

Bryan•12/1/24, 4:57 PM

I've done seperate drives with windows 11 and arch Linux its hard to mess up when it's entirely separate drives

Bryan•12/1/24, 4:57 PM

I've done 2 OS in the same drive haven't had a problem with bazzite

Bryan•12/1/24, 4:58 PM

Maybe I'm being confused are you installing bazzite or are you trying to dual boot

Bryan•12/1/24, 4:58 PM

@Reece Taylor

Bryan•12/1/24, 4:59 PM

Like you already have both drives good for dual boot or are you trying to install bazzite along side windows 11

Reece TaylorOP•12/1/24, 4:59 PM

I had Windows already and was trying to dual boot into bazzite on a different drive.

Bryan•12/1/24, 4:59 PM

So are you trying to install bazzite or boot into bazzite

Reece TaylorOP•12/1/24, 4:59 PM

It happened last time I installed linux

Bryan•12/1/24, 4:59 PM

Reece TaylorOP•12/1/24, 4:59 PM

Well it was both

Reece TaylorOP•12/1/24, 4:59 PM

I've sorted it now though

Bryan•12/1/24, 5:00 PM

On Linux there is a thing called Refind (only works for UEFI mobo which most likely you do have unless your system is super ancient) its a boot menu that is better than grub and it allows you to select windows or bazzite

Bryan•12/1/24, 5:00 PM

I will show you in a bit

Bryan•12/1/24, 5:02 PM

Bryan•12/1/24, 5:02 PM

I can select between windows 11 and bazzite

Reece TaylorOP•12/1/24, 5:02 PM

Yeah I did attempt to use a grub theme I think it's called but it's kinda broken

Reece TaylorOP•12/1/24, 5:02 PM

Bryan•12/1/24, 5:03 PM

You are likely booting into a wrong partition

Reece TaylorOP•12/1/24, 5:03 PM

First of all I have 4 entries for bazzite. I think this is probably normal cuz there's like recovery versions right?

Reece TaylorOP•12/1/24, 5:03 PM

yeah. weirdly it only happens some of the time

Reece TaylorOP•12/1/24, 5:04 PM

I'm guessing it's something to do with the order changing?

Reece TaylorOP•12/1/24, 5:04 PM

not entirely sure though

Bryan•12/1/24, 5:05 PM

So one of the Fedora partitions is the actual bazzite os

Bryan•12/1/24, 5:05 PM

You just have to select the right one, it might be one of the penguin

Bryan•12/1/24, 5:05 PM

I also have like 4 paritions of the same fedora

Reece TaylorOP•12/1/24, 5:07 PM

Yeah it's usually for the top one. But I find when I run into this issue it's for all the entries (Windows included) not just Bazzite.

As I say it doesn't happen all the time but would be nice to change it yknow

Bryan•12/1/24, 5:08 PM

Okay

Bryan•12/1/24, 5:08 PM

What would happen if you boot into Windows?

Reece TaylorOP•12/1/24, 5:38 PM

Same issue

Reece TaylorOP•12/1/24, 5:38 PM

The pic on the right is from when I tried to boot into windows

Reece TaylorOP•12/1/24, 5:39 PM

I can boot into it with the F8 screen of my BIOS

Reece TaylorOP•12/1/24, 5:39 PM

Just not from the menu

Bryan•12/1/24, 5:40 PM

I see

Bryan•12/1/24, 5:40 PM

Its the menu's fault then

Bryan•12/1/24, 5:40 PM

I think that's grub

Bryan•12/1/24, 5:40 PM

Grub lowkey sucks but people will say otherwise

Bryan•12/1/24, 5:40 PM

@Reece Taylor does booting into bazzite from BIOS works too?

Reece TaylorOP•12/1/24, 5:40 PM

Yeah

Bryan•12/1/24, 5:40 PM

I want to make it 100% clear

Bryan•12/1/24, 5:40 PM

Okay then it's grub lmao

Reece TaylorOP•12/1/24, 5:41 PM

Yeah. but I mean sometimes it works through grub and sometimes it doesn't work through grub which is what's confusing me

Reece TaylorOP•12/1/24, 5:42 PM

For both Windows and Bazzite
