Hello, I just wanted to stated everyone that I bought myself a HP Stream 14 and the way I installed Linux Mint (version 17.2 64-bit with Cinnamon desktop) was:
Using gparted, format a USB drive and mark boot as flag
Simply extract the Linux Mint ISO to the USB (no burning or anything further)
Boot the system from the USB drive (through BIOS)
And there you go! Once it's installed just go to Settings and under hardware something (sorry but I installed it in Spanish so don't exactly know the English name for it) select the private drivers for both Wlan and Video (this one with the updated version)
Just that, now it's been working fluently for the last 3-4 weeks. The only thing I couldn't figure out is how to make the trackpad work as it should instead of a 'simple' mouse. But it's far from being crucial.
Linux Mint & Stream 14 work great together, boots in ~15 secs and you have a nice efficient and light laptop with linux.
Thanks to Henry Diaz whose post above made me decide to finally buy this great laptop!!
Thanks for your help - worked great for me.
I used Rufus to create a bootable USBKey with with Mint 19.3 iso image.
