It was working fine with Windows 8 and I wanted to reinstall the laptop to Windows 7 due to virus.
But pressing F2 didn't get me access to Bios. I noticed that some Acer Aspire V5's can't access Bios as it's hidden/locked so I was surfing webs to find solution and I stumbled upon this http://community.acer.com/t5/V-and-VN-Series-Laptops/No-access-to-BIOS-Aspire-V5-571G/td-p/157643/page/5
"The Accepted Solution #1" says download the unpacked bios image then run it through the command prompt. Which I did and F2 did get me to Bios but I faced a really big problem. It's asking for Bios password.. I have never setup Bios password to begin with..
I can't get past this screen. I have tried disassembling the motherboard to pull out cmos battery for 5 minutes and didn't work(I broke my screen doing this). I also tried shorting the password gap(G2201) and this didn't work neither..
When I try to load OS normally it says "Operation System not found"
I'm stuck and I have no idea what to do.. I'd appreciate help!!
