Linux

Hey, so I just put this part up first because this is the one I urgently and importantly need answered even tho I wrote that hideous text block first (sorry English isn't my first language ).

1 So the question is I have live booted mint from a USB and everything is working like I can use internet on it , play YouTube video , the sound is working etc . But I'm afraid if I wipe windows and install mint as the main OS and the WiFi stops working I'll be fucked as I don't have a second machine except a phone to even fix it . There is no repair shop near and the ones I have to travel to go to charge very high for services and all the people I know are " just phone people" . Is it guaranteed that everything that works on a live USB will also work as the main OS ? Also is there a chance that updates could break the functionalities like WiFi, sound , rendering etc ? Cause I'm a layman and idk how to go about installing the correct kernal manually or some shit . And if its something like WiFi that got fucked I'll be extra fucked as I don't have a second device and can't even do it manually . Also as I said I can't afford servicing now . Also how do I switch back to windows lol ? I'm just running mint of the USB o don't know how to go back to windows, do I just pull the USB out ? Then what ? What are the steps on BIOS ? Shit I should've probably searched all these up before bit oh well as long as I'm making a post do feel free to answer idk if I should close my lap or not .I read a post on reddit of a guy whose WiFi stopped working after he made it his primary and he said that it worked on live USB . He was running mint too I believe, same as me with no other device .

Do try and reply to 1 (1 is the most important ) , 2 and 3 importantly and 4 you can do or not according to your free time .

2 Also what is the message on mints website talking about having to do something else for newer devices ? I now use an old thinkpad and it isn't an issue but I'm planning to do an upgrade real soon

3 Also how does the process vary with RISC-V architecture ? Is it there yet ? Any laptop to lookout for or is PC the only way ? I was thinking about switching to risc-v when upgrafing if any company manufactures components or laptop which they do fully as Foss . I am open to building a PC for RISC-V if I can buy full open source parts and if the Linux support is good .

4 I was thinking about switching to Linux for a long time cause I'm paranoid as fuck and always thought I should switch to mint as I'm a layman of all layman and recently got enough time to make it . But then I came to know of zorin OS which too seems to appease to begginers and the conseus between mint and zorin online vary a lot so thought I should just ask here as Lemmy seems to be crawling with Linux users . I mainly just want the drivers or hardware or kernal and all to just work perfectly all the time and not break after updates . I have also heard of some people having kernal issues and having to do it manually in which case I'll be fucked as I'm not savy . I mainly want good privacy and security . Zorin seem to have a paid version and I'm afraid devs will cut back on other version to promote that more and I have no plan to buy premium as i'm just getting into Linux and don't wanna make a big commitment maybe if I used it and settle on it I'll buy to support devs . Also mint is more popular and here to stay kinda shit right ? I don't care much about looking like windows or running window compatible apps and games I'll be just happy with the OS I'm choosing running all Linux shit . Also which appstore is better ? I heard mints software repo holds closed and outdated apps and don't have much idea about Zorin's . fdroid is one of the reason I grew to love android a place for all the good apps with no blobs and have everything I could ever need from galleries to browser . I would also like a that kinda app store supported distro with similar focus and policies on keeping apk updated , and building without proprietary blobs (like fennec ) and only foss .etc .

Sorry for the block of words , mistake grammer etc . English isn't my first language.
