what happens if I flip both to on? Or both to off?

You can have two computers, they are cheap now

I would hazard a guess and these are simply switching the power to the drives.
Each drive has its own power switch.
If one is on, this enables the power to that drive and it becomes the master boot drive and boots.
If both are powered, which ever has the higher priority in the boot list will become the master drive and boot first, causing the other to be just an accessible drive.
If neither is powered then you will get a non booting pc that will likely enter the bios settings only.

r/linuxsucks101 would like a word with you 😂
Honestly GRUB is not a Linux issue, but GRUB itself has tons of issues, and Linux took the blame for it.

You can actually do this pretty easily. You can buy a bank of switches for SATA drives to put in a 5.25” external bay.
Just don’t turn off the drive of the OS you are using while it’s on, I think most OSes prefer their primary drive doesn’t disappear while running lol

I don’t like the look of Linux but that was back in the early days of Linux when it looked like a cross between windows and Apple, someone reply to this and show me Linux now please?

Only problem with this is you’ll constantly be correcting the clock.
When I used to swap hard drives to accomplish this, Linux always assumed the time on the motherboard clock was UTC while Windows always assumed it was local time.
And don’t get me started about all the problems with daylight saving time.

Honestly, if you are going to dual boot, just install rEFInd.

But there is still potential for expansion. A simple 3-way toggle switch would be the next step.

Please tell me that just selects between two physical boot drives

So…
off, off = off
on, off = windows
off, on = linux
on, on = ???
Its got a mystery setting and now I will not sleep tonight.

I used to do this by changing the boot priority in BIOS, I just plugged in one HDD, installed Windows, unplugged it, plugged in the other and installed some flavor of Linux (can’t remember what it was at the time)
Then just used BIOS boot order to switch whichever I wanted to boot!

I struggled so much with grub that I tried Win2Grub and I got it working on the first try.

Just one or could I get a couple out of the deal?
Two settings should be one switch
