Hi I have a little problem with my Y580 and I wanted to check every possibility that there is... I have used Lenovo Y580 / Y480 BIOS v2.07 (5DCN40WW) (don't remember where I got it thought - it was long ago) version of modded BIOS. Short description of problem itself: Last Thursday I've closed lid of my laptop as usual to get it to sleep. When I opened it few hours later I saw Windows 7 boot prompt with two options: boot normally and recovery. Both did the same thing - reboot to this screen again. After investigating I found out that system partition had a lot of files corrupted, to the extend that recovery CD didn't see this partition at all. Many hours later I manage to recover some files and reinstall Windows on *new* drive (I bought mSATA SSD). During installation process laptop has rebooted many times. It worked for one day during which it was rebooted, putting to sleep mode etc. and worked just fine. When I got up this morning I turn it on only to find out boot prompt instead of Windows... There are only few things I can thing about that could cause this: 1. Some virus that is stored in BIOS. 2. Something is wrong in moded BIOS (like controller). 3. I have another partition (big storage) that could have virus two but I doubt it. As you may see there are two possibilities that involves moded BIOS. And like I said - I want to exclude everything that I can in a quest of pin down this issue... This thread has over 100 pages so there's no way for me to read everything. That's way I would like to ask you for your help. Did you have or seen someone who have problem like this? Or maybe you have some tips?
