[Snow Leopard Retail Installation from USB] Out Of Range

[yousef90]

Hi guys, this is my first post

These days I am trying to install snow leopard retail on my pc via usb.

I followed all the steps and managed to restore my usb drive (32GB) for it to be bootable and I set the bios in the right way.

The problem is that when booting from the bios usb pc tells me "out of range 75 Hz-65 Hz, the monitor remains black and I can not install Snow Leopard.

 

Can someone please give me a hand to solve the problem?

This is also my first post. I also got the same error using usb to install snow leopard these days.

 

I edited the com.apple.Boot.plist file under Extra directory on USB thumb

 

Added this.

 

<key>Graphics Mode</key>

<string>1024x768@60</string>

 

before the following line.

 

<key>Timeout</key>

 

Save it.

 

Then, this problem is fixed for me. Hope that helps.
