I'm planning to switch to Linux and I'm curious if I can partition my NVMe SSD to run both Windows and Linux. My idea is to have one partition for Windows and another for Linux, while setting up the BIOS to boot into Linux by default. I'm aware that Windows typically uses NTFS and Linux generally uses ext4 for their file systems, but I'm not clear on how to format just one partition of my SSD without messing things up. Any insights on handling different format types on the same drive would be helpful!

It's totally okay to set up a dual-boot system as you've described. Just keep in mind that Windows has a tendency to overwrite the Linux bootloader when updates happen. If you ever decide to permanently remove Windows, you can easily reclaim that space for Linux. Good luck with your transition!
You're right that Windows and Linux use different file systems. Windows usually goes with NTFS, while Linux often uses ext4. When you're setting up your SSD, you're actually partitioning it first, then formatting those partitions with the specific file systems you need. For dual booting, a typical setup would start with an EFI partition (fat32) followed by a Windows NTFS partition, then your Linux ext4 partition, and possibly a swap partition for Linux as well. I recommend leaving some unallocated space on your drive, so when you install Linux, the installer can take care of partitioning for you. Keeping it simple is always a good move!
You can definitely shrink your Windows partition to make space for Linux. Aim for at least 100GB of free space to create an ext4 partition for Linux using GParted from a live USB. Just remember that while Linux can handle Windows NTFS partitions fine, Windows can't read ext4 at all, so if you try to access it from Windows, you might be prompted to format it—don't do that! When you’re ready to ditch Windows completely, you can delete the NTFS partition and expand your Linux partition into that space.
Linux will automatically install the Grub2 bootloader into the EFI partition, which allows you to select your OS at startup. Just a heads up, you'll want to disable Fast Startup in Windows to prevent issues with the bootloader. It's also worth considering a swap partition during your Linux install, so keep that in mind when you're preparing your drive.
Sounds straightforward! Do you have a guide on managing unallocated space for the installation process?
