I used this: geteltorito.pl -o bios.img n2hur34w.iso and yeah just dd to put it on the usb and booted from the usb and followed the instructions. It worked fine, no issues.
Not sure really, I don’t think so. I don’t have that much installed really. vlc, simplenote, timeshift, google chrome, libreoffice. Obviously more but nothing special.
I think the cpu throttling issue is just related to this lenovo issue. Something to do with a powersaving mode I think which works correctly on windows but doesn’t work as it should on Linux. I think its when the laptop is on my lap not on the desk, the laptop realises this and the feature kicks in. Something like that anyway
