Samsung laptop can't access the bios

my superior officer using samsung laptop (NT530U3C) and he wants change hdd to ssd. First, that model has hdd and Windows8. And he wants to change to Windows7. I think it's start of nightmare.

When I remove hdd and change to ssd, laptop said about 'secure boot'. So I change again ssd to hdd and change the options about secure boot. (I changed these options through Control panel - UEFI settings in Windows 8) -Secure boot: Disable -OS mode: CSM mode After that I change hdd to ssd again. And I install Windows 7. I think it goes well. But after install laptop can't boot. And then I try to fix, I change ssd to hdd. But it also didn't work. So I think use F4 key to access Samsung recover tools and it looks working(hdd). But after recover it also can't booting.

When I power on the laptop, it shows "all boot options are tried press f4 key to recover bios". So I try to access bios, I type F2 to using but I can't. F10 or Tab, Esc other keys also. Finally I think it's matter of motherboard. So I disassemble laptop and get rid of motherboard battery and laptop battery. But it also didn't work.

Some video said using window 8 booting image USB or dvd, can access UEFI options. But it's also can't.

Plz help me. It drives me crazy. I want to escape.

Solution 1:

I'm the writer. I got samsung service. They said my motherboard was borken.(And they said that model's motherboard is 500$.)Anyway...they try re-programming IC on motherboard then my laptop can boot. So if you have same problem with me don't waste time. Just get samsung service.
