Yosemite installed, but drive not recognised on boot

2 posts in this topic

Recommended Posts

I installed Yosemite using the guide here : http://www.insanelymac.com/forum/topic/301138-new-usb-installer-os-x-yosemite-chameleon-r2437/


All is well except booting - I have to boot using the usb installer. If I set my new Yosemite drive as the first bootable drive in the bios, it is ignored (no messages) and the next available drive boots instead.


What I've tried so far:

  • Setting Start Disk to the Yosemite drive using the built-in Mac tool Start Disk.
  • Setting partition active on Yosemite drive.
  • Installing most recent chameleon (v2.3 r2437) on new Yosemite drive.
  • Rebuilding kext caches.


Gigabyte EX58-UD5

GeForce 9800GT 512MB

SSD Boot drive


I am using a DSDT.aml file which I found for my motherboard, which fixes a problem with the resetting of CMOS.

That worked fine on Mavericks - I don't know if it needs to be updated for Yosemite.

Any suggestions - should I be looking at Clover instead?

Or is this just a simpler problem to do with making my boot drive properly active?

Ok, it's a boot0 error problem. The error messages were going past too quickly for me to see them. I tried the solution of doing dd with boot1h from a usb installer to the unmounted Yosemite partition, but it didn't work.

Any recommendations on how to proceed?
