i clicked your HP link. (because the 76 ones are only desktop computers disguised as laptops, really)
then clicked the laptops link.
then clicked every single one of the models and clicked customize.
every single one of the options were Windows 7, 8, 10. Only.
did you manage to go from that page to any actual product you could just enter your credit card and receive with ubuntu?
PS: i should tell you that i'm not being pessimistic. just realistic. My current personal computer is an Asus eeepc-1000, from 2007 or so. the very first netbook with SSD that shipped with linux. i replaced the asus distro garbage with debian right away, but i got it with linux for the meaning of it.
