“Nice to have the OS pre-loaded, but of course anybody who buys a 64-bit Pi will want to reflash to the 64-bit OS. Quite easy to do as you just power on while holding the Shift key. Normally the whole reflash operation only takes a few minutes, however I had one set up that took a couple of hours to complete the "writing" stage. Not sure if it was an issue with the Pi-5 or the SD card, but all appears to be working now as it should.”
