Can't get past choose partition on Windows 8 boot camp install. Then can't remove incomplete installation
I got it (at least the parts in my question) working:


Reboot
Reboot again
Run boot camp and remove old installation (this time it worked)
Reboot
Run boot camp and start Windows installation
At the choose partition screen, choose the boot camp partition, select Drive options, and then select Format.


I wonder why it worked this time, but not the first.
Now I get a error message of corrupt files however. Guess I have to download the DVD image from MSDNAA again.
