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 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

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

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 I've done seperate drives with windows 11 and arch Linux its hard to mess up when it's entirely separate drives I've done 2 OS in the same drive haven't had a problem with bazzite Maybe I'm being confused are you installing bazzite or are you trying to dual boot @Reece Taylor Like you already have both drives good for dual boot or are you trying to install bazzite along side windows 11

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

So are you trying to install bazzite or boot into bazzite

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 I will show you in a bit

You are likely booting into a wrong partition

First of all I have 4 entries for bazzite. I think this is probably normal cuz there's like recovery versions right? yeah. weirdly it only happens some of the time I'm guessing it's something to do with the order changing? not entirely sure though

So one of the Fedora partitions is the actual bazzite os You just have to select the right one, it might be one of the penguin I also have like 4 paritions of the same fedora

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

Okay What would happen if you boot into Windows?

Same issue The pic on the right is from when I tried to boot into windows I can boot into it with the F8 screen of my BIOS Just not from the menu
Bryan

I see Its the menu's fault then I think that's grub Grub lowkey sucks but people will say otherwise @Reece Taylor does booting into bazzite from BIOS works too?
Reece Taylor
Reece TaylorOP3d ago
Yeah
Bryan
Bryan3d ago
I want to make it 100% clear Okay then it's grub lmao
Reece Taylor
Reece TaylorOP3d ago
Yeah. but I mean sometimes it works through grub and sometimes it doesn't work through grub which is what's confusing me For both Windows and Bazzite

Grub is most likely corrupted I suggest use refind As a bootloader menu
