Hi, I need help.
Just install Hi sierra on HP 8200 elite with core i7, and MSI GT 710 . bios version J01 v02.32. Serial Port A
isabled. Booting from USB and Install High Sierra to HD (no SSD hard drive) followed all steps and all installed with no problem. I did the Post install with multibeast (version 10.3.0), using smbios 12.2. and try to reboot from HD. no luck just black screen with blinking cursor. Boot with F9 and select SATA0 under legacy Boot -> Hard Drive -> SATA0 and the same problem just black screen with blinking cursor.
Thanks for your help.
