Hey guys
I have a dell inspiron 15 laptop.Few days ago i tried installing linux on it but somehow i messed up the partitions and landed on a error and changed some bios setting and now i couldn't get into bios by any means.So i want to revert it back to the factory settings since i have to have the access of bios in order to install windows.So how can i hard reset the bios because i cant access it via F keys?
 
try pressing esc or f2 key after switching on. if its not going to Bios. then you have reflash the bios by dismantling the laptop and taking out bios ic and flashing it using programmer with correct file.
