Cannot Start Windows 7 Pro after using Autoruns

HP Pavillion Laptop running Windows 7 Professional

My computer was starting and shutting down slowly, so I began to explore disabling some unneeded services and processes from starting.

I downloaded Autoruns v 13.4 for Windows after seeing it referenced here. I had Autoruns open and put the computer in sleep mode. It was mistakenly

unplugged (and no battery). Since then it will not start, although it passes startup tests from HP software, as well as a Windows repair disc.

When I try to start it, a blue screen with white lettering flashes briefly, saying that Windows was shut down to prevent damage to the computer. It recommends running CHKDSK but I don't

see how I can do that if I cannot start the machine.

 

I just tried a Windows startup test it says

Fallback diagnosis:

Root cause found: Unspecified changes to system configuration might have caused the problem

Repair action: System files integrity check and repair Failed Error code = 0x490

Boot ststus test indicates that OS booted successfully

 

When I try Startup repair, I get the message "Windows cannot repair this computer automatically"

 

I have a system image, but it is one year old. This is perplexing, since I performed a backup a few days ago before starting with this process. The backup cannot

be found, and the one remaining of a year ago would mean a huge amount of work lost.

I am grateful for any suggestions.

Thanks...

AutoRuns is a tool for advanced users since it does not have the ability to recognize unsafe or dangerous items...it only displays what it finds. You should not uncheck anything without investigating first.

If you're going to use Autoruns, be careful using it and be sure to read the following before doing anything on your own:

@hamluis

 

I tried using the command prompt as the article suggests as follows:

Bootrec.exe

bcdedit /export C:\BCD_Backup

c:

cd boot

attrib bcd -s -h -r

ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

bootrec /fixmbr

bootrec /fixboot

 

However, when I entered the line "attrib bcd -s -h -r" I get a message "file not found"

 

Any suggestions? I am not sure about the spacing.

 

As for using Autoruns, I am aware that it is dangerous, and was mainly looking to see what was loading. I always check before deleting things.

The computer shut down as Autoruns was open.

 

Many thanks,

Tom

Hmmm...I would try the suggestions by Gringo at This Post .  Do not follow any other suggestions or pay attention to comments made in that topic.

Thanks

Tap F8 at boot and under the Advanced Boot Options select Use Last Known Good Configuration. Does that work?

Can you boot into safe mode successfully?

 

Can you access the BIOS?  If so...is the hard drive properly reflected on the main page?

I tried system restore

System restore failed to extract the file

(D:\Users\soyeso\Documents\MIDI_Installer-Win-11086\MIDI_Installer-Win-11806)

An unspecified error occured during System Restore (0x80070026)

 

Should I try a different restore point?

 

Thanks

Tried a different restore point, but no go. Same response.

 

@hamluis Cannot boot into safe mode. When I try f8 at startup, it takes me to Windows Error Recovery

Louis, would OP benefit from borrowing a Rescue DVD or Windows OS DVD, has to be the exact same Windows version & edition, and run Startup Repair?  I've fixed a similar no-boot issue a few times with Startup Repair.  Of course, after running it, he would have to give the DVD back to its owner.

I tried the suggestion above from JohnC_21

 

Tap F8 at boot and under the Advanced Boot Options select Use Last Known Good Configuration. Does that work?

 

And actually am seeing the desktop as normal, except for a dialog box saying that System Restore did not complete successfully.

So from a normal looking desktop, where do I go?

 

Thanks

If you have already logged in then open an elevated command prompt. Type CMD in the search box and Right click > Run as Administrator. type the following

 

sfc /scannow

 

This will look for any corrupt and or missing system files.

JohnC_21 I did as you say and the prompt says C:\Users\soyeso>

which is my name and am administrator, but when I tried to run sfc/scannow I get a message saying

"You must be an administrator running a console session in order to use the sfc utility...but I AM the administrator

 

Thanks
