Should i try copying the kexts to the /System/Library/Extensions folder instead? How do i make /System appear in finder? Can anyone help me in pointing out in exactly what folder i should do that? As i don't seem to find a 10.12 folder there. In /Library/Extensions i see the kexts there, so my guess is that i have to copy them on the EFI partition. Seems that it was timing out because it couldn't find the EFI partition and now i see it mounts EFI in Finder. Multibeast used to run in about 5-10 minutes, now in about 1 minute.

If i boot from USB both network and usb work. I am able to boot from the HDD now, but no kexts seem to be loaded, as the USB2 port is not working, and the Atheros card isn't detected. However in an old Mountain Lion box, on Disk Utility, i just see a big 32GB MacOs Extended Format.ĭiskutil list shows EFI and Apple_HFS on the USB drive, and just Apple_HFS and the two windows partitions on the HDD. If i put the USB in windows, i see an EFI folder, and the partition layout is: The question is how should i create manually the EFI partition, which what parameters so i can solve this? Should i try just to copy whatever layout is on the USB drive?

After that, i could install Sierra and continue booting from USB. So i had to boot from GParted (a linux distribution that has a much better partitioning tool), nuke it and format it HFS+. It also cannot erase the partition if i format it to NTFS from Windows. Sierra's installer doesn't see the available space.

My first mistake was to use Windows' partitioning tool to delete the Mac partition and leave it unassigned. Drive A is a SSD drive, for booting Windows 10.ĭrive B has 3 partitions, the first one for MacOS, the second and the third are for Windows storage (apps and games) Greetings everyone, so here's my eternal problem since El Capitan, i cannot get MacOS to boot from HDD, and everything is because i don't have an EFI partition.
