Henry huu Posted August 30, 2021 Share Posted August 30, 2021 Thanks a lot for your opencore EFI, I have finished my istallation of Big Sur on my E470. But now I cannot boot win10 via opencore. Do you have any solutions about that? Link to comment Share on other sites More sharing options...
Baio77 Posted August 30, 2021 Share Posted August 30, 2021 Starting WIN from OC requires special settings at both OC and ACPI level, special care and use of "Darwins" at ACPI level is required to minimize gaps Opencore on Windows You have a DSDT Patch Mald0n, he foresees a WIN boot from Bot Menu Bios and NOT from Opencore, with those acpi patches you will NEVER start Windows To start Win from Opencore the acpi must be finished with _STA method and Darwin or If Darwin as in the picture Some devices must be in some particular sections, for example SB_.PNLF generates problems when starting win from Opencore, PNLF must be under GFX0 I hope I was clear, in case you want to improve I need the ACPI origin of your Hack, you can extract everything with an EFI Debug or with an EFI Clover, doing F1 to the Clover GUI and then F4 and wait 40 sec Link to comment Share on other sites More sharing options...

Baio77 Posted September 13, 2021 Share Posted September 13, 2021 you have a Mald0n DSDT, it is NOT possible to restore this DSDT is full of various patches pass EFI + ioreg and let's use SSDT to boot Win from Opencore Link to comment Share on other sites More sharing options...
