Q: Have been trying to install Windows using boot camp. For some reason after it creates the boot camp partition and starts the windows installation process - it will not show the Boot Camp Partition. Have tried removing all usb devices please help

Using the boot camp utility to install windows. It formats my Mac so there is a boot camp partition. When windows starts to install it does not show the boot camp partition as an option....have even tried to set up my boot camp partition to be 299gb so it would be easily identifiable. Have called applecare and have spoken to geniuses and have had not luck. Even reinstalled mac OS X on my computer to start fresh. Please help.....had windows boot camp on this machine before....windows was updating and lost power. Had to delete my boot camp partition and have not been able to recreate it since.

Mac Pro, Mac OS X (10.5.7)

Do you see this screen? If yes, select the first two options (or just the first one) and provide the location of your W10 ISO when prompted. This USB Installer can be used repeatedly after being built only once.

This is the full Windows Installer. You have two choices. We can either use the legacy BIOS/MBR and try to install Windows or make some more changes and install using EFI Boot. Shutdown your Mac with USB connected, power it up, use Alt/Option key and select Windows (because we have an MBR) and install. If you see any errors, post back.

If this works, we can try the more efficient EFI after removing this BIOS/MBR version using BCA. WE also know how to get a partition created and working at that point.
