new technology for me

[Linux for blind general discussion]

I am interested in buying two raspberry kits and installing linux on both
of them so the linux will talk.  I have access to Walmart and the walmart
app too.  My problem is I've never had firsthand contact with raspberry pi
technology.  One of these raspberry pi kits will be a gift for a good
friend and he definitely needs his raspberry pi to talk since all he can
do with his vision is to see light.  I got interested in doing this since
while trying to help him install slint he shut his computer down at the
wrong time and now all that shows up is grub-rescue when the computer
boots and the other drives only light up temporarily.  I did not tell him
to shut the system down, this was something he did on his own.  I figure
if he has a Pi he can use to connect to his wi-fi he can at least get out
onto the internet with it.
So, what I need to know is what to buy so all of this will work
sceamlessly once all of the installation and configuration is finished.
Both of us have peripherals which may or may not work with the kit.
