On this guide, I got to step 6. Then I skipped a-j, as I was using lion.When I installed mavericks, I installed it onto the hard drive for lion (existing install). Then, I rebooted, to do multibeast (step 4 of post installation using multibeast) and booted on lion. It failed to boot, and gave a black screen with text. Please help!

---Using time machine, I do have a backup from maybe a month before, so it would be nice to transfer the data, if a normal fix isn't possible!---

Thank You.
 
Try booting from your mavericks installer disc/USB drive, then choose your new mavericks Drive to get to multi beast.
 
I think it is has the same black screen... Maybe I should boot in safe mode or verbose?
 
Worth a try, use the flags they recommend on the installation tutorial and in the forums. I think the help "?" shows them too when you're in the boot loader
 
got the same problem
i tried any flag i know
none works it gets to a black screen and computer seem to be stuck

any ideas?
 
Me too - but then I tried "GraphicsEnabler=Yes". By default in Mavericks it's set to "No", which is different from previous versions of OSX. Worth a shot if you haven't already.
 
it'd be nice to know what specs your running.

Me? Check the signature... happy to provide any more info than that if requested.
 
PHP:
i solved my problem with arch=x86_64
 
I have intel core i5, a gigabyte motherboard and gigabyte overclocked graphics chip... Now, when I boot in safe mode, it gives a black screen without text. I will try the other flags.

should I use the "arch..." as a flag?
