First, detach the bootable storage device, and restart your system. After that, detach all the additional USB devices from the laptop. Re-attach the bootable storage device and reboot the system. Hopefully, you will not witness the error message again.

Hold the power button for 5 seconds until it turns off; wait for a while and power it on. When the Acer logo appears, keep pressing F2, and the system will enter into its BIOS mode. A list of options is present on the screen, as you can see. On the right-hand side, it’s written: “Change the order”. Select USB mode and Exit. Hopefully, now Windows will load all the necessary files.

Solution 4: Reset the Active Primary HDD Partition
