Then I grabbed the drivers from Boot Camp and manually installed each one. My problem is the computer does not have a Startup Disk set. I have to hold option and choose Windows everytime I boot the machine up. Is there a way to permanently set the Startup Disk to Windows without OS X available and without using the Windows Boot Camp utility?

I have just taken possession of a new MacBook Pro 17'. I am a convert from being a Windows slave for many years and I must say I am not disappointed so far. I have the machine set up with both Boot Camp and Parallels and have Windows 7 on the other partition. My question is that when I start up it automatically boots into Windows. I have to hold down the alt key to get it to give me the choice of which OS to boot into. I would far far prefer it to boot into Snow Leopard by default rather than Windows or at worst boot up to the 'choosing' page. I cannot seem to find anything that will allow me to change the preferences for this.

By default, your Mac starts up from its built-in hard disk, but a startup disk can be any storage device that contains an operating system compatible with your Mac. For example, if you install macOS on an internal or external drive, your Mac can recognise that drive as a startup disk. You can then follow the steps in this article to start up from it.
Use Startup Disk preferences
When you use Startup Disk preferences to select a startup disk, your Mac starts up from that disk until you choose a different one.
Choose Apple menu > System Preferences, then click Startup Disk.
Click the lock and enter your administrator password.
Select your startup disk, then restart your Mac.
If you see a message that your security settings do not allow this Mac to use an external startup disk, check the External Boot setting in Startup Security Utility.
Use Startup Manager
When you use Startup Manager to select a startup disk, your Mac starts up from that disk once, then returns to using the disk selected in Startup Disk preferences.
Press and hold the Option (Alt) key immediately after turning on or restarting your Mac.
Release the Option key when you see the Startup Manager window. If your Mac is protected by a firmware password, you can release the key when you're asked to enter the password.
Select your startup disk, then click the arrow under its icon, or press Return. If you press and hold the Control key during this step, your selection will be saved in Startup Disk preferences, so it will continue until you change it.
If your Mac is using OS X Lion 10.7.3 or later, you can also use this method to start up from your Time Machine backup disk. Startup Manager identifies your Time Machine backup as ”EFI Boot”.
If you can't select your startup disk or start up from it
Check for these possibilities if you can't see your disk in Startup Disk preferences or Startup Manager, or your Mac won't start up from it.
Check for a compatible operating system on the startup disk

Make sure that your startup disk is using a version of macOS that is compatible with your Mac.
To start up from an external disk with macOS Catalina 10.15 or later, the disk must be connected via USB-A, USB-C or Thunderbolt, not FireWire.
Check startup security settings
If you're using a Mac that has the Apple T2 Security Chip, check the settings in Startup Security Utility. These settings determine whether your Mac can start up from another disk.

Check for Option ROM firmware
If you're in Startup Manager and can't see a third-party startup disk, the startup disk could be using Option ROM firmware. To enhance system security, Mac computers with up-to-date software don’t show devices that use Option ROM firmware until you load their firmware. To do that, press Option-Shift-Command-Period while in Startup Manager. If your startup disk appears, do that each time you want to start up from it or from another disk connected to it.
Mac Os Catalina
If you're using a firmware password, the ability to load Option ROM firmware is disabled as an additional security protection.
