I am using a Lenovo M91p desktop computer with BIOS version just previous to 9HKT58US. I'm sorry I can't see it due to the issue. I believe it is the same except for the 58 is something like a 47.
OS is Windows 7 Pro 64-bit. Hard drive is a Samsung Evo 250 GB SSD. Everything was working fine until I unchecked one program from Startup in msconfig, restarted and it brought me to, literally, a black screen of death. It states:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert Windows installation disk
2. Repair your computer
Info: boot selection failed because a required device is inaccessible
The frustrating thing is that I cannot even boot into Safe Mode. This screen pops up even if you press F8 a million times. You can get to the screen where it shows:
Win 7 Pro
Can use F8
--- or something to this effect, if you use Delete key.
I can use F12 to get to boot selection and select the OS, but it tries to boot up but goes back to this screen. I have NEVER seen this screen before.
I was able to boot to Macrium Reflect, which has six backup images, unfortunately the newest one is two weeks old. But, when accessing it, it does give me four options. I haven't tried any of them as I do not want to make things worse.
I have made a Win 7 Pro disk, which I can boot into. It does boot to the Start Menu. I have several options there, but I am not sure how to repair or if I can install it without formatting the entire drive.
When I looked for issues, I got this:
Problem Event Name: Startup Repair Offline
Problem signature 01: 6.1.7600.16385
Problem signature 03: 6.1.7600.16385
Problem signature 04: Unknown
Problem signature 05: -- 1
Problem signature 06: External media
Problem signature 07: CorruptBootConfigData
The system restore won't work.
Windows Memory Diagnostic Tool is currently running
I am no computer expert, but Problem signature 07 seems bad.
When booting into Win 7, there are a couple of times where it states that the startup function is not working and click to repair. I did. Nothing changed.
If I could get into Safe Mode, maybe I could change the msconfig thing back. I can get to a Command Prompt from Windows, but I am not sure if there is a command that can get me to Safe Mode.
