UPDATE: I'M IN.
Not completely sure how I did it but currently setting up Install Mint.
GOOD BYE WINDOWS

THANK YOU EVERYONE FOR YOUR HELP!! 🌻
And I'll probably need more. Lol
-------‐-------------------

So I guess I'm not installing #linuxmint on my Lenovo Ideapad 300 because I can't get at the boot menu.
(Edit: The Bios won't load, a quirk of Lenovo)
I literally have tried all methods suggested and can't get into it.
Insert USB ...
Turn on + F12
Turn on + F2
Turn on + F12 + Fn
Turn on + F2 + Fn
Lenovo are known for this issue but here has to be a work around I'm not finding on YouTube.

Anyone have a solution to this?
I'm not computer person so please be kind. 🌼
