Dualbooting on different disks

I will not get too long in this part as it's the EASIEST one:

• Install macOS on one of the disks
• Install $(SECONDOS) on the other disk
• Install/copy OpenCore on the macOS disk EFI
• You're good to go

Things to keep in mind:

• Windows can be a bitch when it comes to multidisk setups (it freaks out when it sees a lot of EFI partitions on a lot of disks)
• If the above happens, disable/disconnect all the other disks and install windows as you would normally do
  • For laptops this can be a pain, you can install windows manually by following this guide from TenForums (opens new window)
  • Make sure you choose the proper disk
• You can still refer to other situations if you want to dualboot more than one OS on one of the disks.
• Make sure that OpenCore is on the same disk of macOS for easier troubleshooting and cleaner setup
