The error is 'Still waiting for root device'

Had the same, used an USB3.0 SSD enclosure, I put the drive directly on SATA. I have no idea, but maybe see if you can use a different USB port probably USB2.0 is the best?

"Still waiting for root device".
When installing this means that your USB flash drive cannot be found.
This is usually because the flash drive is in a USB3 port.
If this is the case move it to a USB2 port, if it is already in a USB2 port move it to another and try again.
Repeat until you have tried all USB ports.
Use a USB2 flash drive.
If it still doesn't work you could try another flash drive.
You might also try enabling Legacy on your USB3 ports in your BIOS settings.

Thank you all. I fixed by inserting the usb drive in a USB2 port. I got it installed but unfortunately the installation broke after installing few kexts (stuck at apple logo after reboot). I think I'm going to wait until the final release or a few betas.
