Hi, i just install bigsur on my laptop msi GL65-9SC. I have windows 11 before i install bigsur, on the same disk as windows 11. After i followed post install guide on opencore, i can't boot to windows if i'm using opencore since there's no windows boot option, and i can only boot to opencore using flashdisk. If i remove flashdisk, i only boot to windows.

So i decided to add new boot entry, by following this post [HOW TO] Custom entry in OpenCore to boot Windows

After some tweak, adding BOOTX64.EFI from flashdisk to OC/Microsoft/Boot/ then rename it to bootmgfw.efi (mac), but before that i change bootmgfw.efi (windows) to bootmgfw-win.efi. here's my ENTRIES

It's possible that OC doesn't recognise well the bootmgfw-win.efi file because usually it's named bootmgfw.efi. If there is in the EFI a folder named EFI\BOOT with a file named BOOTX64.EFI inside, try this path:

PciRoot(0x0)/Pci(0x1D,0x0)/Pci(0x0,0x0)/NVMe(0x1,B6-D7-07-44-8B-44-1B-00)/HD(1,GPT,B08491B7-3FDD-47E9-B3DB-CD20D3CD5ECA,0x800,0x96000)/\EFI\BOOT\BOOTX64.EFI

And remember to complete your signature.

Probably something is wrong in config.plist. Upload the file but saying OpenCore version you are using.
