lenovo G505s stuck in a 'diagnosing your pc' then 'preparing automatic repair' loop

my computer is stuck on this stupid loop its been over 5 hours now and its not changing the only aea i can access is through shutting it down then on while pressing the small recovery button next to it and that takes me to several options that arent useful right now. i can restore it because i have very important documents on there so i cant afford to have them deleted. any help please?

i also moved houses and this laptop is over 2 years old so i lost the case and cds that came with it :/

Re: lenovo G505s stuck in a 'diagnosing your pc' then 'preparing automatic repair' loop

Hi heidihamed  , 



Welcome to the Community Forums . 


On a Windows boot loop , it would be an advantage if it can proceed on windows advance options for repair options. 

Avoid any option for factory recovery since those would delete your files.


Initially turn off your pc and remove the battery and charger . 

Press and hold down the power button for 15 seconds and release to drain remaining current. 

Put back the battery and charger and use the Novo key (item5 page 4) to turn it on . 

Choose  BIOS setup and press F9 for loading defaults , F10 to save and exit  

How was it?


If the advance options showed up then we can proceed with troubleshoot and system restore that would allow you to just go back to a previous date before the problem with you keeping your files. 


You may also create a repair image to help fix it from a different pc with same WIndows version. 



Final option should be One key recovery  (page27) but this would delete your files so usually best that you try backing your files via harddrive enclosure and attach the harddrive on a different pc . 

Else booting to a rescue media can help with back ups too. 



Update us how things would go.
