i installed BIG SUR alongside Windows 10 several months ago and it was working without problems,but there were some problems in Windows10 and I reinstalled it,
now when i boot from 'big sur' i get a black screen but if pc goes to sleep and wake up again i find pc work without problems >>This means that every time I want to use MacOS, I must turn on PC > and then leave it until it enters into sleep mode > and then press any key until it wakes up > after that I can work on it !!
- i have disabled IGPU in BIOS- I have completely formatted the hard drive,- And I downloaded the New Big Sur Olarila again,- And I Make New OpenCore 6.8 files again
and still same problem !!
This is my Power Management logs
