# 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
