I have installed Windows 10 on my Mac with BootCamp. This week, Anniversary Update has been released. I wanted to install it. I have launch wizard to upgrade Windows.
Now, even if I press 'Alt' key, the boot menu does not show. Mac OS X starts, slowly... very slowly... very very slowly... When login screen shows up, I can not use keyboard or trackpad.
To start my computer, I need to plug external keyboard and external mouse... Mac OS X is very slow (when I mouse the mouse, I need to wait few minutes before see the cursor movement)
Mac OS X started and logged in, I can use Mac correctly.
I can access to BOOTCAMP partition in Finder. In Boot Camp Assistant, I can not see Windows Partition, whereas in Disk Utility, I can...
How can I start again on Windows without having to reinstall everything?
