Hi everyone, an update. Eventually, it seems some USB flash disks/keys are not bootable. My Verbatim 32GB stick cannot boot for reasons unknown. I decided to test another USB stick on which I had installed Ubuntu some time ago, and via Etcher installed both 5.26 and 5.27.2 and it booted just fine on my MSI EX300 (Celeron 10 years ago) but on the Dell Mini 10V (Atom) the same USB stick didn’t boot, it kept flashing but had a black screen with a blinking cursor. Perhaps the automatic-video-detection didn’t recognise the IGPU. But changing USB stick was the solution. If anyone can confirm that using the same USB stick between computers (x86) is supposed to work with on-the-fly detection of WLAN, BTLE and IGPU, please kindly confirm? Thanks
