I want to get started on Linux and want to dual boot it with Windows 10 because I need to. Any tips? Suggestions? I want to try Arch by the way. Thank you!

Maybe start by trying out Manjaro. It's based on arch but has different flavours of gui's.

Another idea would be to create a Linux VM and try to set everything up according to your needs. (Programs/configuration).

If you want to try using linux, I would go for plain ubuntu. I haven't tried manjaro so I don't know how it compares.

If you want to *learn* linux and you're willing to put in some time to tinker and mess around, I would install arch on a system or harddrive that you can format freely. Chances are you will end up wanting to format your first install even when you get it working; you'll learn so much during it and you'll want to redo a clean install.

I'm on dual boot myself where I use windows for games and linux for productivity. I have one on each physical harddrive which feels super tidy. My bios boots the linux drive which then gives me the bootloader to pick the system. The bios boot vs. grub loader was what confused me the most before I got it working - I thought these were the same concept.

I second the VM approach. I was trying to find a good linux distro back in the days of ubuntu 10.04 and did a dual boot. Back then I was an avid windows users where I had a lot of 3rd party tools for various kinds of work (Programming, Image, Videoediting etc.). Unfortuanetely I encountered a lot of problems in the long run when I would update the system or weird specific errors with IDE´s. The learning curve of linux as well was steep enough back in the day. In the end I just could get more shit done faster on Windows than on linux but nonetheless it helped me greatly in knowing the linux ecosystem a bit better through that. I am still curious about some specific linux distros like Kali, Mint, damnsmall linux and tinyme though. Today I use a windows cygwin approach and am happy with that.
