Windows 7: Windows 7 repair installation attempts fail

Windows 7 repair installation attempts fail

After trying to run an auslogics registry defrag program I've been stuck with blue screen stop errors. Every attempt to resolve this with a system restore or a repair installation has been blocked and there appear to be no solutions.

I'm running Windows Home Premium 7 64 bit

By ths way, the DVD drive on this computer does not work, so my only reainstall option is though USB, but all attempts encounter roadblocks.

Starting in safe mode
goes directly to blue screen
stop 0x000000f4

When I get the computer to start from a USB stick
I get
windows is loading files
install windows

setup is starting
please read the license terms

accept the license terms

which type of installation do you want
I choose upgrade
then I got

compatibility report

the computer started using the windows installation disc remove the installation disc and restart your computer so that windows starts normally
Other attempts get an an install driver screen, bu there's no hint on what driver is needed or where to find this driver. Again, I'm trying to run the installation from a USB stick that's already inserted in the computer.

I try

boot rec /fixmbr
the operation completed successfully
bootrec /fixboot

the volume does not contain a recognized file system


bootrec /rebuildbcd
total identified windows installations 0

I try

chkdsk c:\f

chkdsk discovered free space marked as allocated in th master file table
windows has made corrections to th file system
8kb in bad sectors
failed to transfer logged messages to the event log with status 50




System Restore says

No restore points have been created on your computer's system drive

There's a chance that there are restore points on the c: drive but I can not switch the system drive to c:

When I try

scf /scannow the response is

there is a system repair pending which requires reboot to complete restart windows and run sfc again

They I try

sfc /scannow /offbootdir=c:\ /offwindir=c:\windows

This does not work.


I ran windows memory diagnostics. No problems found


startup repair says

startup repair could not detect a problem



So every option encounters an unavoidable roadblock.

I've searched over an over again or a solution but nothing works and every sugesstion leads to an unworkable dead end.

Hi

If the original issue is caused by a registry error, you might be able to replace the corrupted registry hive files from the backup copy. Usually Windows will keep a backup copy inside "C:\Windows\System32\Config\Regback" folder. I would suggest carefully reading the below tutorial which covers step by step instructions on how to do the registry restore.

Thanks for the help!
This method worked where others failed.

Also, this serves as a warning to not use Auslogics Registry Defrag. +

A better option which has no bad reports during the entire 5 years of Windows 7 is Puran Defragger which offers a boot time defrag that includes System files which are not running during a boot scan.

In fact registry is not something which needs regular maintenance. You should read what Microsoft says about "Registry Cleaners".

Microsoft support policy for the use of registry cleaning utilities

Quote:
Some products such as registry cleaning utilities suggest that the registry needs regular maintenance or cleaning. However, serious issues can occur when you modify the registry incorrectly using these types of utilities. These issues might require users to reinstall the operating system due to instability. Microsoft cannot guarantee that these problems can be solved without a reinstallation of the Operating System as the extent of the changes made by registry cleaning utilities varies from application to application.
Windows is a closed source operating system and nobody other than Microsoft knows which registry keys are wanted and which are not. Letting a program to delete Registry keys ( which it thinks as not necessary ) may create serious issues than doing any good. Simply stay away from anything which claims to clean or optimize the Registry.

The exception would be CCleaner. We've never seen a single case here of Windows 7 damaged by CCleaner, while we regularly see problems caused by "Registry Cleaner" sales scamware advertised in pop-up ads. None of these work. CCleaner is safe using both the Disk and Registry cleaner.
