Windows Safe Mode stuck; Booting hangs or goes in loop
When you try to boot your Windows OS in Safe Mode, but find that the Windows Safe Mode is stuck at Please wait or Loading files screens or while loading classpnp.sys, disk.sys, amdkmpfd.sys, aswardisk.sys, etc files, then this post offers suggestions that may help you get out of the problem.
Windows Safe Mode stuck
This Safe Mode error can occur due to several reasons including hardware failure, software corruption, corrupt files in the system, corrupt drivers, and issues with the BIOS. When your Windows 10 PC is stuck on some screen or message or it means that the OS is unable to locate and load the system files that are required for the process to complete.

Once here, you can now use CMD to run commands. You may use a Windows 10 DVD or a bootable USB drive, or you can burn Windows 10 ISO to a USB drive using another computer and then use it.
Once you have accessed the Advanced Options, you can use several options offered below to resolve the issue.
- Run Startup Repair
- Run System Restore
- Run Windows Update
- Run System File Checker using CMD
- Change Startup settings
- Reset BIOS
