I found out how to solve this problem. According to some other user, Secure Boot needs to be disabled. So I went into the boot settings and disabled it.
Now I have a different problem. It seems that the Windows 7 installation disk is recognized. But it encountered some sort of bug.
The following text is printed to the screen inside of a little console window that takes up 1/8th of the entire screen size:
Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
- Insert your Windows installation disc and restart your computer.
- Choose your langauge settings, and then click “Next.”
- Click “Repair your computer.”
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
Status: 0xc000000d
Info: The boot selection failed because a required device is inacessible.ENTER=Continue ESC=Exit
Trying to Continue does nothing. Trying to Exit also does nothing.
And what is that status? Is it some kind of pointer?
