HELP Installing Yosemite on Intel DH77EB

[robertbratu]

I am using Unibeast. What changes do I have to do to Yosemite? If I enable UEFI in BIOS, OS X does not work anymore, until I disable it again.

What about enabling both UEFI and Legacy and then the other steps I listed.
Does too disable the disk containing OSX in mSATA port?

For Chameleon/Chimera boot loader nothing special in the BIOS other than choosing what you had for installation .

But I don't know enough about Clover Bootloader. I have used a couple of times and gave up because of long booting time compared to Chimera /chameleon on the HDD. I have not done much tests on Clover after that.

I don't remember seeing "Legacy boot" inside my Intel BIOS, I will check again, but "Internal UEFI Shell" definitely is nowhere.

I have not used that board. But have seen other models of Intel and made a guess. You may not have such options and hence you may be limited as to how you can tweak it any more. I guess you can transfer this SATA or SSD containing Yosemite to a non- mSATA port and use the mSATA to connect another SATA drive to be used as Storage Disk.

Ok so I just bought an mSATA to SATA adapter, since my computer does not boot straight from mSATA, unless I press F10 for to enter boot menu. I was hoping to solve the problem, but it's the same. It looks like my motherboard does the same with every SSD, unless I enable UEFI in the BIOS. But if I do that, Yosemite has problems booting. After the Unibeast screen (or whatever it's called) show up, I get a short error message which I haven't memorized. It says something, then to press any key. And if I indeed press repeatedly any key, Yosemite will finally boot after a couple of minutes.

I would like to be able to not reinstall OS X. So what do I need to change so that it will boot fine with UEFI Enabled in BIOS? I read somewhere about needing to install Clover Bootloader. Is it possible to switch from Unibeast to Clover now?

Thank you guys for all the tips! One of the problems was Vd-t, which I was not aware that it had to be disabled

How did you disable Vd-t? I have the same MoBo but can’t seem to find the option anywhere in bios
