Administrators Bronxteck Posted December 1, 2020 Administrators Share Posted December 1, 2020 so it boots from usb but not internal drive. then the problem might be it does not see your internal volume. what type of drive is it? as for the firmware update using cd roms. usualy you use an app that can boot from an iso or converts an iso to a usb bootable device. and boot of of that.

Moderators Jake Lo Posted December 1, 2020 Moderators Share Posted December 1, 2020 @ronald77 When you press F12, do you see a boot option call OpenCore? Link to comment Share on other sites More sharing options...
ronald77 Posted December 1, 2020 Author Share Posted December 1, 2020 @Bronxteckyes, it boots from the installer USB I made, with the same EFI. The drive is a Sandisk X400 256 GB SSD. @Jake LoYes, the option OpenCore is there (see attachment) Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 1, 2020 Moderators Share Posted December 1, 2020 Did you select Opencore from under UEFI boot? When OC picker shows up, select Reset NVRam. It'll reboot back to OpenCore picker Here, you select MacHD to continue booting Or try booting from USB installer and run First Aid from disk utility Link to comment Share on other sites More sharing options...

Crumbling Posted December 2, 2020 Share Posted December 2, 2020 You don't need Windows to upgrade the BIOS. Chuck the EXE into a FAT32 partition, select BIOS Flash Update in the F12 boot menu and point it to the file. Link to comment Share on other sites More sharing options...
