Windows 7: Windows boot configuration data file does not contain a valid OS entry

Windows boot configuration data file does not contain a valid OS entry

Not sure if this is the correct forum, please forgive me if I've posted it in the wrong forum.

Hi folks Iím a newbie to the forum and would really require some assistance, Iíve owned PCís for a considerable time and I am pretty flummoxed with a problem Iíve encountered. I havenít a clue how this occurred and for the life of me cannot seem to recover my PC. I have used various approaches on your forum to hopefully correct this issue but to no avail.

When booting from disk I get the message the file
File: \Boot\BCD Status 0XC0000098
Info: The windows boot configuration data file does not contain a valid OS Entry

I used the helpful guide ĎHow to Fix Windows When it fails to Bootí on this form and ran the following: Initially running system repair

The computer scans itself during this phase and looks for windows installations it returns the message no windows installations found. When I view the Diagnose and repair details I get the following:

No OS files found on disk
Repair Action: Partition table repair
Result: Failed error code 0X490

I have ran the repair process 3 times and booted between each repair

I progress beyond this and run the following:

Bootrec.exe /Fixmbr runs successfully
Bootrec.exe /Fixboot runs successfully
Bootrec.exe /RebuildBCD runs and returns successfully scanned windows installations
total identified windows installations: 0 completed successfully

My Laptop is a 4 year old ACER 8390G running Windows 7, it has a Hitachi 500Gb hard drive and the partitions are as follows:
Partition 1: Recovery 15GB
Partition 2: Primary 225GB
Partition 3: Primary 221GB
Partition4: OEM 3565MB

I donít really know what Partition 1 and 4 are and I can only assume partition 2 and 3 are the OS and Data files.

I have ran a CHKDSK /f and /R all stages complete and successful, doesnít appear to find any errors on the drive. The /R (all stages complete) but it says windows has made corrections to the file system.
Iíd be forever grateful if I could have some assistance on seeing if I could get the operating system up and running. I believe there is nothing wrong with the hard drive as I can see files on it and at the dos prompt can list directories and files.

My Bios shows the hard drive

I have a recovery CD and have a copy of partition Wizard but not really sure how to use the latter.

Is it possible that something has got deactivated on my drive.

Please Please help. Thanks in advanceÖ JD
