Windows 7: Boot loop after unexpected power outage

15 Oct 2017   #1

Windows 7 64-Bit SP1
Boot loop after unexpected power outage

Greetings. I'll cut to the chase. It is as the title says. Below is what I have tried to do:
*I apologise that I could not remember which Windows 7 version I have.

1) Starup repair doesn't work. This was the details it given:
Problem signature:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21199922
Problem Signature 05: AutoFailover
Problem Signature 06: 21
Problem Signature 07: CorruptFile
OS Version: 6.1.7601.
Locale ID: 1033

Session Details
System Disk = \Device\Harddisk0
Windows directory = D:\Windows
AutoChk Run = 0
Number of root causes = 1

Tests performed include system disk test, disk failure diagnosis, disk metadata test,
target OS test, volume content check, boot manager diagnosis, system boot log diagnosis,
event log diagnosis, internal state check. All completed successfully with error code 0x0.

2) System Restore Issue:
System Restore failed to extract the file (D:\Program Files\AVAST Software\Avast\aswAMSI.dll)
from the restore point. The restore point was damaged or was deleted during the restore.

3)I didn't make a system image because prior to this event, I do not know about system image recovery.

4) Windows Memory Diagnostics showed there wasn't any problem and automatically rebooted my PC with the issue not fixed.

5) Using command prompt, I tried this:
Startup Repair Infinite Loop Recovery - Windows 7 Help Forums

chkdsk for my D drive(windows and system drive) and E drive(where I put my games) showed no problem
aside from reporting error due to error 50.
SFC /scannow - No integrity violation (Done thrice)

6)And, no, I do not own a Windows installation disc. System repair function is already built into my PC so
a system repair disc would be redundant isn't it?

I'd like to avoid buying the Windows 7 installation disc unless it is the last resort.

I'm having eye problems momentarily, I might have missed it: What happened when you tried to do an F8 boot?

F8 boot sometimes allow me into ABO, sometimes into boot priority option. It must be the timing. In ABO, I tried Last Known Good Configuration but to no avail. I haven't tried other options. My PC is running an advanced memory diagnostics right now. The one I mentioned above is the standard one.

Update: Advanced memory diagnostics detected no problems. If getting a Windows installation disc is really the only option, would someone guide me to find out what version of my Windows 7 is? Apparently winver does not work and systeminfo | findstr /B /C:"OS Name" /C:"OS Version" does not work too. I also tried changing from X: to D: (system and windows drive) and type in the same command and it does not show, saying that both of them are not recognized as commands. I tried it on my functional laptop and it showed the correct information, so I have no idea why it would not show in the command prompt in system repair.
