Stuck on grey screen before install/ CMOS invalid

[tboandfshady]

Unable to open /var/db/bootcache.playlist

Hey i am in the process of hackintoshing my 4540s.

I have created the bootable Mavricks usb, but when i boot it, the apple logo loads up and the loading thing starts spinning and thats it! i have left it on for a hour and nothing is coming up.


Also to be noted whenever i restart my probook after that it gives me a CMOS error and resets it before letting me boot into windows or back in to the usb drive.


i have found this thread:
http://www.tonymacx86.com/hp-probook/70875-4320s-wont-boot-install.html#

and his solution of:

''I can now boot to installer with -x.''

apparently doing that boots it, but just what does ''-x'' mean and how do i do it to get into the installer!

If you Boot from the USB the First you see is the Bootloader.
There you can enter several Bootflags which affect the Booting.
Just Type -x, its the flag for Safe Mode, If you wanna know where it actually hangs Type -v for verbose mode.
You can combine different flags.
Try -x and -v

Please provide complete details in your profile.

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.

Boot verbose (-v) and post quality photo of the entire screen.
