I'm really worried about messing things up with my PC and potentially losing all my data. Right now, I have Windows installed in Legacy mode, which doesn't support Secure Boot. I'm contemplating wiping everything and reinstalling Windows to prepare for future game compatibility, but I'm not super confident with tech stuff. I've backed up my data to the cloud, but I'm skeptical about the whole process since I'm alone without my friends to help. What should I do?

Absolutely back up your data! You should also update your BIOS and then use a tool called mbr2gpt to convert your system disk. Set the boot type to UEFI and enable Secure Boot. This way, if something fails, you'll have your backup to fall back on.
First off, make sure to back up all your personal files—think photos, videos, and documents. After that, you can reinstall Windows with Secure Boot enabled. It's really important to have that backup in case anything goes wrong during the reinstall process.
You'll need an 8GB or larger USB stick for this. Create a Windows installer on it, and don’t forget to add your network drivers. After backing up your important files, go into your BIOS and configure it for UEFI mode and Secure Boot. When installing, delete existing partitions and install Windows on the large free space.
If you can, buy a new drive, swap it with your old one, and reinstall Windows there. Once it’s set up, you can add your old drive back in and copy your data over.
Before you start the reinstall, make a list of essential software you'll need. Ensure you have access to everything you need like your passwords—especially if you rely on your browser to fill them. If you've got an external drive, consider using Disk2Vhd to create a backup of your entire C: drive.
