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.
