HELP!! Win 7 Crashed. Will not boot up

[bkolt]

My desktop (Gateway GT5465E) crashed a week ago. It would come up in safe mode with networking so I ran malwarebytes, hijackthis, and several other diagnostics. I removed over 300 malware objects, checked a validation problem and tried to run the driver verifier. It stopped running and crashed again. This time it would not come back. It was looking for a boot disk. I put in my Win 7 repair disk 32-bit. It ran the startup repair twice but could not repair it automatically. I sent the information to Windows. The details list Root cause found:

Unknown Bugcheck: Bugcheck a0. Parameters = 0x1, 0x6, 0x84dfa020, 0x0.
Repair action: system files integrity check and repair
Result: Failed. Error code = 0x490
Time taken = 1265651 ms

I have no restore points for some reason.
it cannot find a system image to use for recovery
I can access a command prompt.

Can you help me get this running again.
If I can get the Win 7 disk, will I be able to reload it?

You need to run Startup Repair at least 3 times, with re-starts in between each run.

How to Run a Startup Repair in Windows 7​

I would recommend to run Startup Repair again, 3 seperate times with re-boots each time.​

To be sure there is no more system errors run SFC /SCANNOW Command - System File Checker​

When you get it running, start a thread in the System Security forum, they can help you be sure that all the malware is off your system.​

I have run startup repair way more than 3 times and Windows will not start. I keep sending reports to Microsoft. I tried running sfc in the command prompt but get a message that a repair is pending and I need to reboot. I reboot and it comes up in the repair menu. Windows cannot repair this computer automatically message comes up - send the report - send more information -- Click finish and shut down. or veiw advan ced options. Back to recovery options none of which will work. Sfc says : "There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."
Did that 3 or 4 times. same message everytime.

I have my gateway recovery disks but cannot seem to access them.

I desperately need my computer to work. I do not have the Win 7 software disk and my recovery disk doesn't work. What can I do to fix this?

 

[Dave76]

You should have a Gateway recovery partition, check your manual on how to access it.
On the boot screen you should see options on the bottom, one of these should tell you the 'F-key' to press.

Let us know how it's going.

I seem to be locked in a loop of running the startup repair. When I hit f8 I do get a menu but it will not boot up in any safe mode. The start up repair cannot find the root cause. It sends reports to microsoft. Sometimes it says Inknown Bugcheck: Bugcheck a0, Parameters = 0x1, 0x6, 0x84dfa020, 0x
Repair action System files integrity check and repair
Result: Failed, Error code = 0x490
time taken = 1286728 ms

I can get to the C prompt. I can see all my files but cannot access them.
Is there any commands I can use from the command prompt?

I think I have a problem similar to u a few months ago, I copied all my work, files, everything to an ext HD using command prompt, then I reinstalled my OS. Took many many hours but it is better than nothing. But a few files were missing and I dun mind.

 

[bkolt]

I ran the startup recovery suggested by Dave, but it still did not boot normally. The startup repair is running again and taking a lot longer than before. If it still does not fix the problem, how do I backup my files from command prompt to my external drive?

 

[zane80]

http://www.sevenforums.com/tutorials/682-command-prompt-startup.html

However, I cannot remember exactly the exact command to type in to copy everything. You might need to find it out yourself.

The copying for me too hours as I have around 400gb of items to copy. Make sure u have a large ext HD drive.

Good luck!!

I have a TB external drive. It has 503 gig free. It is my second TB drive. the other one is full from backups and photos. not sure what all I need to back up. Some files were already on my TB drive.

 

[Dave76]

Try this one:

MBR - Restore Windows 7 Master Boot Record

It has the command line entries.


If that doesn't work you can try this.

As per this tutorial, you can fix it with these commands:

/fixmbr................do the mbr first
/fixboot...............do the bootsector next
/rebuildbcd...........do the bcd last

You can also put the OS HDD into your external drive and copy the files, but will need another computer to do it.

Backup everything, its safer. Good luck!!! and patience

I do not have a CD with Win 7 on it. I am waiting to get that from the tech that installed it. He should have given me a backup copy back then. I have 3 repair cds but all they have are 3 files: bcd, boot.sdi, & bootfix.bin

 

[Dave76]

I can get to the C prompt. I can see all my files but cannot access them.
Is there any commands I can use from the command prompt?

Can you still get to the command prompt?

My last post has links to the commands to fix your MBR from the command prompt.

Dave,
The instructions for mbr require a cd. I do not have a cd. the files it needs are not on my repair cds I looked. How can I do this without a cd? I am waiting for the tech to bring me the Win 7 cd but don't know when that will be. Is there a way to download it to another computer and burn it to a cd? This ACER doesn't have a cd drive but my kid's computer does.

How were you getting to the command prompt before?
I was under the impression that you could still access the command prompt.
All you need to run those commands is the command prompt.

This tutorial will show you how to download the files to make a system repair disk.

How to Create a Windows 7 System Repair Disc

NOTE: If you have a OEM Windows 7 instead of a retail Windows 7, then you may need to use OPTION TWO below to create a System Repair Disc with instead.

OPTION TWO, To Download a "System Repair Disc"
NOTE: This option is perfect if you do not have a retail Windows 7 installation DVD and only have a OEM Windows 7 recovery DVD or partition.

3. To Burn the System Repair Disc to a USB Flash Drive

A) You can use the Windows 7 USB/DVD Download Tool to burn the ISO to a USB flash drive.
​

This only creates a repair disc that boots to the System Recovery Options screen to allow you to only repair any Windows 7 on any computer with Windows 7 installed. You can use the command prompt option to run commands though.

Another option:

How to Create the Ultimate Bootable USB Flash Drive

You can add any ISO program file onto this USB bootable drive and add an easy edit to the loader file and have a bootable USB tool drive that will work on any computer.
I have used this and it is very easy to do.


As another alternative, you can try this:
You can also put the OS HDD into your external drive or buy an external enclosure and copy the files, but will need another computer to do it.

If you put your OS HDD in the external then connect it to another computer, you can access all the files you need to recover.

After this is done, put the HDD back into your computer and then re-install your OS.

Instead of ignoring the suggestions I took the time to write out, why not reply so I can give you others ?

To copy out your files use this: Copy & Paste - in Windows Recovery Console

All of the boot repair commands are automated in Startup Repair if it finds an installation to repair. What were the exact results?

Run Gateway full factory recovery using it's hotkey at bootup. Gateway Support - Full Factory Recovery

If it fails, you'll need to order Recovery Disks from Gateway or find/borrow a Win7 installer, unlock all versions if necessary to reinstall with the Product key on COA sticker. Unlock any version eicfg removal tool

Hi bkolt,

Let's try one thing at a time

You have a win 7 repair cd already.

Boot it up, go to command prompt and type:

Diskpart

lis vol

( find the drive letter of your win7 partition - use that instead of ? below )

exi

SFC.EXE /scannow /offbootdir:?:\ /offwindir=?:\windows

Gregrocker,

I am not ignoring your suggestions. I am trying not to wipe my hard drive. I don't have all my files backed up to the external drive. How do I move directories from the Prompt? I have no way to reload Win 7 until I get a CD copy of it. I do not know when the tech that put it on my computer will get it to me. I have access to the System Recovery Options that allows me to get into Control Prompt. I can read CDs on Drive D, My partition is on Drive C My external TB drive is E. What happened to my D drive partition? Is that now X? Is there any way to recover my win 7 without wiping the hard drive? If not, how can I back up subdirectories in the command prompt? My backup system was not working before the crash.
