I plan to do a pc upgrade very soon. Alongside that I plan to start with Mint or Fedora. Is there any real or big downsides to dual booting ? Aside from the harddrive space lost ?
If I like or really like my time with Mint I would probably switch permanently but I felt like I wanted to test it for a couple of months before making a complete switch.
Im a big 
so that impacts my consideration. Dont really play much multiplayer shooters so I dont have a problem with kernel anticheat games not working.
If you dont know how to unfuck a bootloader after a windows update nukes grub then no dont do it. Also you cant share storage cos ntfs on linux is a fuck and windows will lock ntfs partitions on shutdown and gets weird if it doesn’t unlock it itself. Installing on separate drives isnt even relevant advice anymore since most computers moved from MBR to GPT ages ago unless your bios specifically has legacy mode support.
If nothing I said makes sense then the answer is a very firm no. You cant brick anything but if you dont know what youre doing run with the assumption you may have to wipe the drives so dont do it if you have stuff that isnt backed up or that you arent prepared to lose.
Anticheat is moving to demanding secureboot so dual booting wont even work as a solution and neither will a vm with hardware pass through
I've been using Linux as my main desktop OS since before 2000 and I second everything said here.
I hear some people talk about windows updates but shouldnt that be a non-issue on windows 10 since there are no more upadates for that ? Or am I wrong ?
In theory sure I have a strong feeling you’ll just acquire 20 more headaches and with secureboot anticheat and whispering of tpm 2.0 requirements for anticheat the headaches wont really even solve the problem.
I’ve used linux for about 15 years now and i dont think ive ever experienced a stable dual boot ever that didnt require me to fix grub in some way. The order also matters you install windows first and linux second the other way round will disappear the grub bootloader lel. And with gpt and uefi bios the headaches grow.
Personally im waiting for the industry to change its mind it causes less problems
For a second I thought you said nfts. Not my precious ape pictures
You should be able to fix this by turning off safe boot on windows
