I am not too sure what you mean by "level of the 4 windows stage" but try possible solutions below:
***Accessing Advanced Start‐up when PC isn't loading:***
If your device isn't loading or stuck during boot, you can use this method to access the recovery environment:
1. Turn on your PC.
2. As soon as the Windows logo appears, press the ***power*** button to turn off computer.
3. Repeat steps 1 or 2 two more times.
After the third interruption, Windows 10 will open into the ***Advanced Start‐up*** environment
***While in the Advanced start‐up environment, use the following steps to use Start‐up Repair:***
1. Click the Troubleshoot button.
2. Click the Advanced options button.
3. Click the “***Start‐up Repair”*** button.
4. Select your account.
5. Type your account password.
6. Click the Continue button.
If the above doesn’t help do the same as above but this time select “***System Restore***” from the
“***Advanced Options?***”
***Or from an installation disk/flash drive***
1. Boot from the the installation media for the installed version of Windows.
2. On the Install Windows screen, select Next > Repair your computer.
3. On the Choose an option screen, select Troubleshoot.
4. On the Advanced options screen, select Startup Repair.
