How To Update Bios Using Thumbdrive for Acer Aspire 4730ZG  

actually the reason im using pendrive is just to flash bios for the laptop,im using windows seven original starter disk.

Plug in only one HD to try install.

If this fails, try wiping the HD first if you haven't: SSD - HDD Optimize for Windows Reinstallation

Try setting SATA controller to IDE to see what happens.

thanks gregrocker,

I will try your method again,hope it will works,

i already consult a computer technician,he said that my motherboard got some problem,maybe i will post a video in youtube to explain the problem more efficiently.
