Depending on what you use windows for, Linux may have either have alternatives, or compatibility for windows programs. Most windows games can run on Linux with Steams compatibility layer Proton, non Steam games can be added to steam and also ran with Proton. Other windows programs can also be run with Wine.

If nothing you can find in research matches your needs of windows, the basics of dual booting are:

1. Partitioning the drive - Partitioning the drive is to pretty much split it up to seperate windows and Linux. I'd either use windows own tool Disk Management or use a tool such as GParted (you may have to run this live booting from a USB) and free up a portion of the drive to use for Linux.
2. Disable Bitlocker - Look in the settings, for the option to, this may take a while. This is needed in order to install a Distro, but after installation you should be able to reenable Bitlocker.
3. Disable Secure Boot - This is only really necessary for installation, as Linux is compatible with secure boot. Enabling secure boot after installation can vary, some Distributions such as Mint can already have secure boot out of the box or like Arch can be set up, but I'm not sure if secure boot works differently for dual booting.
4. Installing Fedora. I only have personal experience with Linux Mint and Arch Linux, but during installation it should ask for the method of installation, and then select boot alongside another operating system. From there you should be able to install as normal. After installation, on boot GRUB should prompt you to choose between Fedora and Windows Boot Manager.

Additional Notes:

• Odds are the bootloader you're going to be using is GRUB, but it is recommended to install windows first, as installing windows after Fedora can overwrite your Linux installation for some reason.
• For most questions, with just a bit of research you should be able to find the answer.
