Installing Dual boot Windows 7 and Pop_OS

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:

  1. Insert your Windows installation disc and restart your computer.
  2. Choose your langauge settings, and then click “Next.”
  3. 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?
