Installing OpenCore on a legacy system

At the moment there is no official support for MBR/Legacy based Windows installs, there are plans though unlikely to see anything anytime soon: Add MBR loading tool to OpenCore (opens new window)

Currently, there are 2 workarounds:

• Convert Windows into a GPT based drive(this means you will have to boot with OpenCore each time)
• Chainload rEFInd which does have support

For the latter:

1. Setup rEFInd (opens new window)
2. Add BlessOverride path for rEFInd(\EFI\refind\refind_x64.efi)
3. Boot OpenCore
4. Chain-load rEFInd
5. Select Windows
