Yosemite won't boot from HDD on XPS 8500

[PointTwoOne]

Better stay away from the System Definition MacPro 6,1. Use MacPro 3,1 or select appropriate one for your configuration from here : http://www.everymac.com

1. Boot with your USB again.
2. Rerun Multibeast
3. Select "Drivers > System > Patched AppleIntelCPUPowerManagement > OS X 10.9.0"
4. Select "Customize > System Definitions > Mac Pro 3,1"
5. Install it.
6. Reboot and check booting from HDD.


Good Luck...!

When I boot into the HDD from the USB I get a black screen and my monitor switches off like there is no input. What should I do? Try again?

Use the same boot flags which you had used for installation.

I am using the flags 'dart=0, GraphicsEnabler=No, nv_disable=1, IGPEnabler=No, -f, -v' it boots and I get to the log in screen, I enter my credentials, hit enter and then the loading disk spins. How could I fix this?

How long you waited there? This may take bit time to reach desktop.

Also please note no comas (",") are required in between the flags only single space is fine

I have left it over 18 hours and it still is not letting me in! Should I use the guest account?

I rebooted, used "dart=0 nv_disable=1" booted well, logged into the guest account fine, downloaded MultiBeast, make your suggested changed. Rebooted. Works perfectly, the booting problems have also been solved too!

Remove OS X HDD/SSD, keep only the HDD/SSD where you want to install Windows
Then install Windows, install required drivers.
Connect OS X HDD/SSD.

Check booting of both OS.

Thanks. I managed to do it dual booting on the same drive with a partition on it. Thanks for your help.
