Reading more about the early 14in HP Stream like mine think its 14-ax010ca Anyway the bios doesnt support nvme. And nice workaround with rEFInd-duet, guy in video gave a link, just need the EFI folder out of it, has the nvme driver included.
But then some guy posted that he got it working by going into bios and setting it to try and boot from "network" first. Sounds goofy but honestly have yet to see any bios written by a sane person, the mrchromebox UEFI bios maybe comes closest. Most bios seem more likely to have been written by Mad Hatter from Alice in Wonderland. I remember some of weirdness in getting older bioses to boot frm usb, when that was a new thing. Some it was easiest to set to boot from floppy or cd and stick in PLOP disk. Boot PLOP and let it find the usb. That one guy said booting first from network worked on his without rEFInd-duet or CLOVER. Course he was ignored, though I will try it. So just depend which adapter I get first. This Stream like the Dell chromebook has M.2 wifi socket, not mpcie. Oh and it can take upto 8GB RAM. The 14inch all had soccketed RAM, just one but socket none the less. Older ones can take max of 8GB. Guess newest ones have two sockets and can max at 32GB DDR4. Honestly with celeron cant imagine any of them actually needing/using more than 8GB. Though suppose if you have 24 tabs open in your browser or some fool thing like that. 8GB of DDR3 less than $10, so be worth it just out of curiosity whether it makes a difference. With Puppy, probably not, with window, likely would. Processor going to be the bottleneck once storage and RAM are upgraded.
