I am Using Lenovo G405s and running Windows 8 on my laptop, and whenever I turn on the laptop this error pops up -
SATA HDD : WDC WD5000LPVT-24G33T1 boot failed
SATA ODD : MATSHITA DVD-RAM UJ8DB boot failed
Network Boot : ATHEROS boot Agent boot failed.
Default Boot Device Missing or Boot Failed. Insert Recovery Media and hit any key. Then select Boot Manager to choose a new Boot Device or to Boot Recovery.
I used USB/CD to re-install Windows but it didn't work.
I thought that my hard disk have some problem, but when I connected it to another computer, it was working fine.
