In this video I will show you how to install Windows 10 Legacy BIOS so you can dual boot your OCLP Unsupported 2009-2013 Mac with macOS Ventura, Monterey or Big Sur. UPDATES & CHAPTERS BELOW!
When installing Windows 10 + OCLP, we have 2 different ways to install, UEFI & Legacy/MBR. A Legacy BIOS install can have better reliability and less driver issues for 2013 and older Macs.
For Late 2013-2015 Unsupported Macs you can install Windows 10 UEFI.
Part #1 Install Windows 10 UEFI & Dual Boot OCLP macOS Monterey with Bootcamp!

DISCLAIMER: Please understand that installing macOS Ventura or Monterey on your unsupported Mac is a best effort by the community. A ton of work went into getting the patcher to work! Some things might not work exactly right but its really really close. I would not recommend installing on a system that you rely on for work or school. ALWAYS BACKUP YOUR FILES FIRST BEFORE YOU UPGRADE! The good news is that you are getting the latest security fixes from Apple. Some might argue that upgrading to Patched Monterey makes your Mac safer since Apple is no longer fixing security issues on 10.13 and below.")
