RE: Inspiron 660 "locked up" loading Windows 10 (error code Oxc000000f) from Windows 7
You are entirely hozed. You need to reformat drive and reinstall from scratch.
Windows Boot Manager
Windows failed to start. A recent hardware or software chance miht be the cause. To fix the problem:
1. Insert your windows installation disc and restart your computer.
2. Choose your language settings and click "Next."
3. Click "repair your computer."#
Info: The boot selection failed because a required device is inaccessible.
