Holding down the option key (⌥) at startup brings up the boot manager, allowing the user to choose which operating system to start up.
When using a non-Apple keyboard, the alt key usually performs the same action.
The boot manager can also be launched by holding down the “menu” button on the Apple Remote at startup.
On older Macs, its functionality relies on BIOS emulation through EFI and a partition table information synchronization mechanism between GPT and MBR combined.
It was really nice and straightforward, just like I was running a proper Windows PC.
If you're a huge Apple fan, but you're tempted to give Windows 10 a spin and see how it feels, now you can.
Switch over to your Boot Camp installation of Windows, and open the Apple Software Update tool.
Install all the updates on that side, and then you should be free to use the normal Windows installation tool to update your version of Windows to Windows 10.
The utility guides users through non-destructive disk partitioning (including resizing of an existing HFS partition, if necessary) of their hard disk drive and installation of Windows device drivers for the Apple hardware.
Want to update the version of Boot Camp (and related drivers) that it is running - I don't think it has updated since I partioned and installed Windows 3-6 months ago and I know there have been updates.
My end goal is to perform the free upgrade to Windows 10 without reinstalling but I am trying to get Boot Camp in order from the beginning.
Setting up Windows 10 on a Mac requires a USB flash drive and the ISO image of Windows 10 provided by Microsoft.
Boot Camp reformats the flash drive as a Mac bootable install disk, and combines Windows 10 with install scripts to load hardware drivers for the targeted Mac computer.
Since you'll be using Boot Camp Assistant to basically install a new version of Windows 10, you'll grab any new drivers and such that you need as part of the installation process.
