Stops on boot + bootloader problems

[redwood36]

Hi all, I installed lion on a seperate hdd, no problems.

Then I installed lion over my snow leopard installl and now I'm getting frozen in boot.

I receive the following error before it stops.

Usbmsc identifier (non-unique): 07a30209d5b90687 0x13fe 0x3623 0x100

0 0 appleusbcdc: start - initdevice failed

Repeat 3 times

 

 

I used the instructions stickied in the thread for easy install via usb on this forum.

Additionally if this can be solved id like to get rid of how long it takes to boot into. Right now every time the boot loader asks for me to select a hdd, when I do it in bios already, then spends a long time in a grey screen loading kexts.

Thanks !

Edit I used " a fast and easy way to install lion"

also it take a long time in the grey screen toread hfs+file:

Sys info

Asus p6t deluxe v2

I7

Nvidia 285

6g ram

 

edit again,

I notice when booting into my separate (first) install that it bypasses the USBmsc (which follows firewire) and goes straight into the next step. Also there is a failure in the firewire (which again precedes USBMSC) which is basically pretty similar in structure.

Neither of these errors occur with my Lion Trial install (which is the first install, henceforth referred to as Lion Trial install).
