All I can find on this topic is that one
OS on NVME and the other on
SD card, is that true or can you have
different OS’s on the two NVME option
An easy way to get dual boot is to use pinn OS, you can find it in raspberry pi imager, Misc utility images. Multi-Boot your Raspberry Pi with PINN - Pi My Life Up
I meant having 2 operating systems on 2 nvme drives in the pironman 5 max case. Is that an option?
I mean Ubuntu on one of the NVME drives and Trixie on the other
I’m not sure if pinn OS can install OSs on 2 differents nvme. You can try…
The Max case has a dual NVMe PIP module. This lets you connect two SSDs, and you can install a different operating system on each one. You can also install another system on an SD card. This allows you to switch between them when you boot up.
Can you tell me how the pironman5 max knows which nvme disk to boot from? Does it give you a choice at boot?
If you have two NVMe system drives and need to choose one to boot from, edit the /boot/firmware/cmdline.txt file and change ROOT=PARTUUID=xxxxxxxxx to the target disk’s UUID.
To find the disk UUID, use this command:
ls /dev/disk/by-id/
But if you want to choose OS on each startup, I think Pinn OS is a better choice but I’m not sure if it install different OS into different nvme. I’ll able to try it in a few days, when I’ll receive my nvmes.
Finally, pinn OS can’t install 2 OSs on different nvme.
is there any way to choose which nvme drive to boot when the Pi5 boots? without having to modify the boot config at each switch on? I’m thinking of something similar to GRUB2 but for the PI. I realise GRUB is x86 (PC) based, but. is there something similar on Arm?
I don’t think so. If you want to multiboot from one nvme, you can easily make it with pinn OS.
Weirdyguy is correct. If you want to select the OS at boot, this can only be achieved using Pinn.
