I have a Acer 4620 notebook that just started to NOT BOOT!!! When i turn on my notebook, it gives me the options to start in safe mode, safe mode with command prompt, or go to the last known good configuration. NEITHER ONE OF THE OPTIONS WORK!!!!!! I dont know how to restart or recover my PC!! I Dont have a Recovery disc..... WHAT DO I DO PEOPLE?!?!?!?
It should have a recovery partition to restore it to the way you got it, if you don't have the manual for it you may need to contact Acer.
However that would loose all your data, I don't know if there is a non destructive repair option.
If you don't have the recovery partition then you would need to purchase a set of recovery disks from Acer.
