Can't boot without flash drive plugged in

[Wicked131]

Hi guys

Just installed Mavericks on my PC, but it won't boot without flash drive plugged in and using "-x flag" command.

My pc:
- i3
- Asrock h77 pro4/mvp
- 4gb ram
- sapphire hd5670

Also what I noticed I can't search for applications using spotlight.

What should I do?

There's only one hard drive in my pc and only one operating system (mavericks)

Boot with -v and post a picture of the screen where it hangs. It helps us help you as "won't boot" is not much help.

Install NullCPUPowerManagement or patch AICPM.
