I recently bought a new laptop, it came with windows 10 home single language, after a few days of usage and due to my work I needed to install windows 10 pro (or Linux) to try to avoid issues with the drivers I decided to go for windows 10 pro, the problem, it was a pain to mame the laptop boot from a usb stick, the bios was very confusing about this option, the only bootable device was something called "windows boot manager" after disabled various "security options" I was able to start and format the hd with a windows 10 installer (it has multiple versions home and pro) and usually asks for the version to install in the machine, but this time it did not ask, just installed windows 10 home (whaaat?) and in somehow restored the previous windows key (oem key) I don't understand how was that possible, I'm thinking im reformat with Linux to wipe out the hd and remove the previous windows flavor.
Have you experienced something like this? What can I do to install a different version of windows? Does this windows version keynis kept in the bios?
