I use PINN to dual-boot between the 32 bit and 64 bit Raspberry Pi OS. When I boot to the 64 bit version PINN exits and the screen blanks, but then the ACT light repeatedly flashes slowly 7 times. When I boot to the 32 bit version it starts up fine. Is this problem SD card corruption or a different problem?

Update: I re-copied the /boot files and it boots, but now my mouse and keyboard don't work. What's wrong now?

    Have you read the 'not booting' sticky on the RPF forum? Especially the Pi4 section at raspberrypi.org/forums/viewtopic.php?f=28&t=58151 – Dirk Jul 9 at 18:10
  • The thing is that the system boots, but not the OS. Also see my update above – dominic03 Jul 9 at 18:57
  • You should ask the PINN developer/maintainer at raspberrypi.org/forums/viewtopic.php?f=63&t=142574 – Dougie Jul 9 at 20:15
  • I reinstalled and it works now. Unfortunately sudo doesn't work after reinstalling! I can't win! – dominic03 Jul 9 at 21:53

I reinstalled the Raspberry Pi OS and it worked, I don't even know why it stopped working in the first place
