Reboot before reaching the installer

[uku]

Hi

I had Yosemite on my PC before, but messed with the settings and could not enter the OS. Now I would like to make a clean install with El Capitan.

Intel Core i7 CPU
GeForce GTX 280
ms 7522
x58

I reach this:


I'l choose the Boot Mac os X from USB... black screen with apple logo and then reboot...

I tried to load with GraphicsEnabler=Yes PCIRootUID=0 ( last Yosemite install worked with those ) and also tried with nv_disable=1

Also disconnected other HD, but with no luck.

I think BIOS settings are right...

Any simple ideas to fix it?

Thank You

You should try the following boot options :
cpus=1 nv_disable=1

GraphicsEnabler=Yes and PCIRootUID=0 can be removed

But it after Options/Boot Args:dart=0

Thank you, removed dart=1 and entered cpus=1 nv_disable=1 and it loaded the installer.

Please put your specific motherboard model, CPU model, and GPU model into the system configuration area on the left, and/or your signature. It's hard to give you good advice without having that information on hand on every post (just in the first post is not good enough).

Then, please boot verbose (space bar from the Clover menu) and post a photo of the text on the screen just before the reboot.

Please put your motherboard model into the system information area on the left.

Then search the big list of solutions for "row of plus" and see if the suggestions there help.
