Welcome to InsanelyMac!

 

Please provide us with some specifications about your system (CPU, Motherboard, Graphics & Model Number if applicable). Adding more specific information allows us to respond quickly with more precise answers. Chipset, LAN, Audio & If your Graphics are integrated or not, are excellent additions.

 

You can also place this information in your "Signature". It will then appear on every post you make. This can be done via My Controls: http://forum.insanelymac.com/index.php?act...rCP&CODE=00

Is there a reason you are tying to boot into Single User Mode?

 

Try booting with the boot-flag

platform=X86PC

 

Still waiting for root device

This is generally one of three things:

1. If you are using PATA (The old IDE Ribbon Cable Drives) you will want to make sure that the drive you are installing to is set to MASTER via the jumpers and the actual drive itself. Id also recommend that you have the drive on the cable's first connector.

 

2. If you are using SATA drives try going into the BIOS and changing the SATA Mode from AHCI to IDE.

 

3. Chipset related. If your booting the install disk and are getting this issue and the first two do not fix the problem its probably chipset related. In the case of SATA, some motherboards have more than one SATA control and so one or the other may be compatible. You can check your user manual or online to see if this is the case and then plug into the appropriate connector.

 

Boot-Flags

Ideally you should boot in Verbose Mode until you have your machine running the way you want. This can be done by using the -v boot-flag. When you start the computer up you will see the Darwin bootloader screen. This screen will count down and by pressing the requested key will give you a prompt to enter these boot-options. Now instead of getting a gray screen with Apple logo, you will get useful information about the boot process and see at which line it hangs on.
