So a friend of mine has this HP Stream 14 laptop using eMMC 32 GB storage. He know wants to replace this eMMC harddrive with an faster SSD.
for what i have learned from searching the web, the EMMC technology is a flash based memory stuck onto the motherboard.
Is that correct?

So simply; Will it be possible for him to replace this eMMC harddrive and install an regular SSD?
What kind of cables is necesary for this procedure?
How will this affect his current Windows installation?
Is Windows just going to work as before, using and bootable USB and create a new bootable USB for his Windows installation?

I would be superhappy if someone here could provide me with the correct answers in order for me to arrange this installation.

Attached you will find some images regarding his computer.
