During recent update Windows 7 failed to boot. Various attempts to "repair" also failed. One attempt did report it was due to a corrupt file:\Windows\system32\drivers\aswvmm.sys.

 

Have seen this mentioned several times here in the forum and always with a custom result. Can you help me.

 

Thanks

Any time you are posting about a problem like this it is a considerable help to list the make and model of your computer or - if it is a self-build - the main components and the details of your OS such as SP1, 32 or 64 bit. But, no matter.

 

Have you tried booting in 'Safe mode' - usually achieved by tapping 'F8' while the BIOS screen is showing (the one with the maker's name all over it) ?  If you have tried 'Safe mode' will it boot into it ?

 

If you can get into 'Safe mode', choose the 'with command prompt' option. When you get to the command prompt type 'sfc /scannow' - note without the quotes and that there is a space between 'sfc' and /scannow - this will then attempt to fix any corrupted files. When it has finished running if your computer doesn't automatically re-boot, re-boot and see what happens.

 

If this doesn't work for you, post back with the details of your computer and a note of what 'various attempts' you have tried. After all, there is no point in asking you to repeat something you have tried and didn't work.

Hi Chris

 
It is a Compaq laptop with an AMD semperon (?) processor running WIndows 7 64 Bit Ultimate.
 
Cant make it to safemode. Windows repair run several times - no luck.  Have made a full image, Than ran Spinrite 6  level 2, Than ran EasyBCD EasyRE. The next Windows repair produced the message about system32\drivers\aswvmm.sys.Removed drive and did D7 external "SFC" and eventually restored my backup image.
 
Still cannot boot to safe mode. Get boot options, can select "command prompt', it tries to get me there but returns to not able to boot message.
Have also tried to run SFC from command prompt in windows repair but it says can't run sfc because a repair is pending, restart and try try try again :)
 
Ed

You have post that it is a Compaq, but have not posted the model.

 

Instructions for a Windows 7 Repair installation.

 
A Windows 7 Repair Installation will require a installation disc.
 
If you do not have a Windows 7 installation disc you can download a free legal ISO image of Windows 7 SP1 at  Windows 7 Forums.  You will need to download the same version of Windows 7 that you have installed,  This image is hosted by the Digital River store which is an official distribution partner of Microsoft.  This is a genuine untouched image which is safe to download. 
 
Attention:  If you do have a Windows installation disc, skip Part A and go to Part B, Step 1b.
 
Part A, Steps 1a - 6a
 
How to burn ISO image using Windows Burn Disk Image.
 
Notice:  This applies only to Windows 7 and Windows 8, earlier versions do not have this.
 
1.  Place a blank CD or DVD in the tray of your optical drive and close the tray.
 
2.  After you have downloaded the ISO image you want to burn right click on the Start orb, then choose Windows Explorer.
 
3.  When Explorer opens click on Downloads in the left pane.  Scroll down till you find the ISO file you want and double click on it.  Click on Burn Disk Image.
 
4.  In the image below you will see Dick] burner:, this should be set to the optical drive you want to use.  Click on Verify disc after burning if you want to Windows to verity the disc image after burn.  Click on burn.

5.  In the image below you can see that the green progress bar, when the image is finished burning the bar will be filled.
 
burndiskimage2_zps17a9d6ff.png
 
6.  After the image has completed being burned click on Close
 
Please note:  In order to boot from this DVD you may need to change the boot order in the BIOS so that the CD/DVD-ROM is the first device in the boot order, and the hdd is the second device.
 
 
Part B, Steps 1b - 10b
 
1b)  Place the installation disc in the tray of the CD/DVD drive, close the tray and restart the computer.
 
2b)  You will be prompted to press any key to start the installation, I find the space bar handy.
 
At this point the setup process will load files, this will take several minutes.
 
3b)  You will now need to choose the  Language, Time, currency format, and Keyboard or input method that you'd like to use.
 
After this is done click on Next.
 
w71_zps6dbda47e.png
 
4b)  Click on the Repair your computer link at the bottom-left of the Install Windows window.
 
This link will begin the Windows 7 System Recovery Options.
 
w72_zps2a656a0c.png
 
5b)  System Recovery Options will now search your hard drive(s) for any Windows 7 installations.  This will take several minutes.
 
No participation is required on your part at this time, wait till it has finished and the next window opens.
 
w73_zpsd5483f05.png
 
6b)  Choose the Windows 7 installation that you'd like to perform the Startup Repair on, then click on Next
 
w74_zps490f9a17.png
 
7b)  Click on the Startup Repair link from list of recovery tools in System Recovery Options.
 
w75_zps9941e858.png
 
For a future reference, there are several other diagnostic and recovery tools available in the Windows 7 System Recovery Options including System Restore, System Image Recovery, Windows Memory Diagnostic, and Command Prompt.
 
8b)  The Startup Repair tool will now search for problems in the system files.
 
If Startup Repair finds a problem with any system files the tool may suggest a solution which you will need to confirm, or may solve the problem automatically.
 
w76_zps3dd75d83.png
 
9b)  Startup Repair will now attempt to repair whatever problems it found with system files.  
 
Note:  If Startup Repair did not find any problems with system files you won't see this step.
 
w77_zpsd8be95eb.png
 
Important: Your computer may or may not restart several times during this repair process.  This is normal, you should allow it to continue until you see the Restart your computer to complete the repairs window. 
 
10b)  Click on Finish, this will restart your computer.
 
w78_zpsd49257fb.png
 
It is possible that the Startup Repair will not be able to fix the problem.  If the Startup Repair tool determines this, it may automatically run the the repair after your computer restarts.  If it does not automatically run the repair but you are still having problems with Windows 7 repeat these steps to run Startup Repair again manually.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Restart the Repair Installation.  When you get to 7b where you have the choice of System Recovery Options and click on Command Prompt.

 

When the Command prompt opens type in sfc /scannow and press Enter.
