Hi folks,

Just ran the update as per instructions and I can boot the HD by booting from USB first, then using -v -x to boot from hard drive. I can't boot directly from the hard drive using -v -x, it still stops loading. This is quite confusing as they should be loading from the same source?

Booting without these flags results in the grey load screen bar not moving. I have run multibeast after booting from usb to hd with -v and -x, it still wont boot from the hard drive at all.

Attached is what I get in verbose mode booting directly from the hard drive. Any ideas?

Here's how I got around the "can't find; mach_kernel" error.
I followed the steps in this guide and still got the error. My problem was that there are two ways to boot from your usb:

1. let chimera load, press any key to bring up the device list, and choose usb.
This resulted in the error

2. press F12 before Chimera loads to bring up the boot menu and choose usb or in my case PMAP.
Using the bios boot menu instead of the chimera boot menu allowed me to boot to the installer without any trouble.

Hope this helps someone!

THIS!! Fixed "can't find mach_kernel" for me too, thanks!!

Maybe update the first post ? Seems bunch of people run into this..
...and thanks to Tony and everybody / anybody else contributing to make this stuff work :):headbang:

No, that's why the title of this thread states "...Using UniBeast and MultiBeast". :rolleyes:
