HA OS 13.2 - RPi 5

I’ve just invested in a Raspberry Pi 5 to run HA, but I’m having problems creating the disc image. I’ve used the RP installer 1.8.5 and selected the HA 13.2 image for the RPi 5. The resulting disc does not have a mountable boot partition. I’ve tried two different types of storage (USB stick / SD card) to no avail. Any ideas anyone?
PS: I’ve raised an issue on Github, but seen no response so far.

BUMP - surely I’m not the only person with this problem? Just flashed a bog standard ‘bookworm’ image and that boots fine.

IGNORE - I discovered that there is no windows mountable partition.
