So let me start off by saying that I'm a complete beginner at Linux in general. I wanted to install Ubuntu along Windows 10 to learn slowly. I did this by booting off of a flash drive, but I made the mistake of thinking when it said it would replace everything, that it meant just on the flashdrive. So after managing to remove my entire OS (thankfully there was nothing important on my hard drive), I need windows back so I can sucessfully install Ubuntu on the side.
Now I have a windows 10 iso on a flash drive, and when I go to install it apparently, I somehow have a FAT32 hard disk now, which in result I get a prompt stating that I can't install windows to fat32.
I can't seem to find many articles on what to do because I'm unsure whether I have to completely wipe my HDD or if there's an easy solution to this. Any guidance someone can help me out with will be greatly appreciated!
