Even if you manage to extract the installer.wim
from the windows installation media, replacing your windows files will only further damage your current system.
I recommend you to create a Windows 7 System Repair Disk; you will need a working Windows 7 System for that:
- Open the Start Menu, then type
recdisc.exe
in the search box and press Enter. - Insert a blank unformatted CD or DVD into your CD/DVD drive and click on the Create disc button. NOTE: If you are prompted to insert a Windows installation disc, it means that the files needed to create the system repair disc cannot be found on your computer. Insert a Windows 7 installation disc.
- It will now start creating the System Repair Disc.
- When it's finished, click on the Close button.
- Click on OK
- Remove and label your new Windows 7 System Repair Disc from the CD/DVD drive.
Then use the newly created repair disk to repair your damaged system.
Alternatively you can try Hirens Boot CD(Download / Boot From Pendrive).
Hirens Boot CD Features a Mini Windows XP which can allow you to determine the root of the issue and - if possible - fix it.
In case all fails, install a new windows on top of your current windows (Custom Install
***
). All your files will be moved to Windows.old
folder on the root of the drive and the drivers will be located in Windows.old\Windows\System32\Drivers
.
However this approach does work, it is recommended to download setup packages for drivers from your pc manufacturers website.
Sidenote: If you have registered programs, most programs store their license information in the Registry(Windows.old\Windows\System32\config\
), AppData (Windows.old\Windows\System32\config\systemprofile\AppData
) and ProgramData(Windows.old\ProgramData\
)
You can mount the old registry entries from your old system into a hive in the new system.
Just make sure you copy over all the programs stuff into the same locations on the new OS and copy the license information / registry entries (Export -> Unmount Hive -> Import
).
Another Note: if the folder Windows.old
already exists, the folder all your current files will be moved in will be Windows.old (2)
etc...

Make sure to select the correct partition of your broken OS, AND DO NOT FORMAT, just continue installing.
