I have an article about USB dual boot - https://www.spket.com/blog/raspberry-pi ... dual-boot/
It shows how to install OS manually, it's for Raspberry Pi OS, Ubuntu is similar.

Does Celeste work through Steam on TwisterOS on the pi4?
It's much cheaper to buy right now than at other places.
Bastion is XNA game too, it has a demo version, could you test it on Twister OS?

Re: Celeste on the Raspberry Pi

What's the FPS after overclocking?
Celeste also has OpenGL version, will it get batter FPS than XNA/FNA version?

/boot for different OS?

I'm trying USB dual boot, /dev/sda2 is RPOS 32, /dev/sda3 is RPOS54, the problem is /dev/sda1, which can be shared between 2 OS? I know config.txt, cmdline.txt and kernel img need be different, what else?

no /dev/input/event*

After switch to USB boot, X windows has no response to keyboard/mouse. after check Xorg.log, I find out that /dev/input/event* all missing. If I boot into 64bit OS, the mouse works fine on X windows,and there are 3 event* in /dev/input. what could cause this issue?

Re: STICKY: USB-MSD boot EEPROM third update - 2020-06-12

Does /boot has to be FAT file system? does it has to be first partition of SSD? I place it as same partition of /, and it report "unable to read partition as fat",

undervoltage for SSD usb 3.0 but fine for HDD usb 2.0

I have 2 external storage, SSD usb 3.0 and HDD usb 2.0

HDD usb 2.0 is working fine.

SSD usb 3.0 will get undervoltage warning if cold booted(poweroff), no matter in USB 3 or USB 2 port. but it won't get undervoltage warning if I boot OS using sudo reboot!
