So im about to buy a new laptop but it only has a hard drive and linux on it. I want to add a M.2 ssd to it and install windows 10 on the ssd. So my question is, when installing windows, i will get the option to choose where to install it and there will probably be a list of partitions from the hard drive. Should i delete them and more importantly, what do they have in them? My friend told me they have drivers in them, so if they really have and i delete them, will i have to go and download them again?
