I have an old hp pavilion dv6 and I installed windows 7. Then i tried installing Ubuntu 24.04 and the USB wouldn’t boot, it just showed “GRUB” in the top left of the screen. I tried with another USB and the same issue emerged.
I’d try other (lightweight) distros for that case. Since your PC is old, it may not fulfil the latest Ubuntu’s system requirements.
