I am speccing up a new pc at the moment with the plans to install bazzite or Mint from the start,

I have booted into Mint on my laptop off a usb several times but never committed because I have so much stuff on said laptop in concerned about losing.

I tried to put it all on an external hardrive but because of the stupid fractured way windows saves files everywhere in the cloud two random desktop folders etc for no apparent reason in not confident in getting all my photos etc and fully commiting
