Hello! I was having trouble printing And decided to restart my laptop. Upon restart, it began loading as usual and then a message stating "preparing automatic repair" appeared at the bottom of the Lenovo  logo. After about three minutes the screen turn black with no lettering and remains on that screen despite numerous restarts. I never got to the point where it was going to allow me to sign on. When I press the Novo button on the side and attempt to access the boot menu it takes me back to the black screen. I really need my work docs.

Please help!!

Does the Startup repair message appear each time you boot the system?

Have you tried removing the AC adapter and battery, and then pressing and holding the power button for 10 seconds or so before reattaching everything and attempting to boot up?

Are you able to enter the BIOS via the NOVO button?       If so, you might be able to enable Legacy Support from the Boot options, and set USB boot as the first device to enable booting to Windows Installation Media on a USB thumb drive to attempt repairs. 

Best of luck, 

I don't think it is a BIOS issue, but rather an issue with the hard drive or a corrupted Windows installation/update.    But if you can enter the BIOS, you should also have access to the boot menu as well, so If you have access to another computer, you can use the link below to create a a Windows 10 Installer DVD or USB flash drive, and boot from it to attempt a repair of your system. 

Note:    If you have important files that you do not have backed up, you may want to consider having a computer tech mount your HDD on another system to back up your data before attempting any repairs, because if the HDD is the problem, the more the drive is accessed, the greater the chance data backup/recovery could fail.     On that model it is pretty easy to remove the HDD and then access it from another system by installing it into a USB to 2.5" SATA drive enclosure etc, and copying the contents of C:\Users\  folder to a USB drive or CD/DVD.  

Have you heard any new clicking sounds etc. coming from the area of the HDD (front lower right) recently?

Once it boots from the installation media, you would want to select "Repair you Computer" and attempt a System Restore, or Startup repair etc., but again backing up your data first would be advisable since the cause of the problem is unknown.

Yeah, If it is not under warranty, I would probably take it to a local computer shop and have them backup your data first before trying any repair, plus they can check the drive to see if it is failing.   Most computer shops have a device like this that they can just drop your laptop drive into and access the files, so it should not take long to backup and diagnose the hdd.

It could be that the drive is OK and a System Restore or Refresh will correct the problem, but I always like to backup the data first before attempting any repair. 

Best of luck,
