System does not boot and shows strange characters

[Ebbi]

Hi all,

I haven't used my Hackintosh for a while.
Now I wanted to boot the system again, but it doesn't even start the boot loader and only shows crap on the screen:

Who has seen this before and could tell me how to fix it please?

Thanks a lot!

Try This.

Good Luck

Great, thanks!
I wonder what happened to my existing bootloader.
How can it disappear if the hard drive is unplugged?

One more question:

Do I remember this correctly that I could connect the Hackintosh disk to a real Mac and then I launch the Chimera installer and install it onto the Hackintosh disk?

Update:

I just wanted to see if Yosemite boots from the USB stick.
When the system tries to access the USB stick, Chameleon shows up and I can boot my system without a problem.

This is weird.

Update:

I followed the procedure from P1LGRIM's answer and now it works again as it should.

Just to throw in my $.02, I don't think the bootloader "disappeared" - it's there alright. It just got corrupted. Sh** happens.
