If it is not detecting the operating system then most likely it gets corrupted. Did you get a BSOD message prior to that? BSOD usually appears if Windows encountered a problem that it needs to stop completely. It can be hardware, software of driver related. If you have installed new software or hardware then got the error, then that may what cause the problem. Try to do a system restore by logging into the safe mode and restore to a previous point prior to the installation. Also, computer may experience BSOD if your Windows partition does not met the minimum amount of free space needed to boot up the Operating System. 15% of a drive’s capacity should be free at all times for windows to load. You may also want to run a virus scan via the safe mode. Updating to available windows service packs and updates can also be of great assistance.

This can happen if there is an external drive connected to the computer via USB when booting the computer. To fix the problem, check the USB ports of the laptop if there is a USB flash drive or external hard drive connected. You should also check the card reader on the side if there is an SD card inserted.

Remove all USB devices from the computer including any SD or microSD cards. There shouldn’t be any external drives connected to the computer when booting. Start the laptop again and see if it works. If this doesn’t work, go to the BIOS and check the startup drive. Restart the laptop and press DEL, DELETE, F2, or whichever key is configured to go to the BIOS.

In the BIOS, go to the drive section and check the first boot option. If your laptop has an optical drive, set your hard drive as the first boot and your optical drive as second boot. Save the settings and exit. See if this works. Also, make sure the optical drive doesn’t contain any disc when booting the computer because it will also prevent the system from booting.
