Comment 13 for bug 1905491

This affected me. I downloaded kubuntu-22.10-desktop-amd64.iso on Jan 20, 2023. Initially, I used dd to write the .iso to a 32GB USB stick (PNY), and again using balena Etcher. In both instances, I booted the resulting Live USB on my "pre-2015" HP Pavilion g7-1070us Notebook PC. I was presented with the GRUB menu, but selecting *Try or Install Kubuntu I was briefly shown "Error can't find grub_platform" and then the blinking cursor in the upper left corner. A power off is required at that point. Based on the error message, I Googled and found this report. The fix; converting the GPT of the created LiveUSB to MBR works. But this really does need to be addressed and fixed. Not everyone has modern, UEFI capable, PCs. I don't. Lessor informed users, or those without the trouble shooting skills, will be turned off by the experience.
