Bootup Error Vista - \Boot\BCD 0xc0000098/No OS found on disk

Hello

An Acer laptop could not boot up Vista. It goes straight to Windows Boot Manager menu returning below error:

FIle: \Boot\BCD
Status: 0xc0000098
Info: The Windows Boot Configuration Data file does not contatin a valid os entry.

And once I boot my computer via Vista Recovery CD and choose Repair Computer, I cannot find drivers to load and if I click next and do startup repair. It shows No OS foudn on disk as an error.

Ths issue prior to this was "boot manager failed to find os loader" and the situation now seems worse after I tried playing around with the boot commands under command prompt.

I have done the chkdsk f/ c: twice and now no errors are found.

Any feedback on how to resolve this would be greatly appreciated.

P.S. I prefer not to go for option for Factory Default Setting via Recovery CD from Acer.

Thanks

Do you still see the file and folder structure in command prompt of vista recovery console now?

If no, it is very likely that it cannot be fixed.

How many partitions do you have? Dual Boot?

OR

Follow the approach below.

Reinstall Your Boot Loader Manually From the Windows DVD

Alternately, if it doesn’t automatically detect anything to fix, you’ll have to choose your own recovery options.  Click the bullet option on the top then click Next to use recovery tools to fix Windows.

Now, select Command Prompt from the available recovery tools.

In the command prompt window, enter the following to repair your boot loader:

    bootrec /rebuildbcd

After a few moments, it should detect your Windows installation and ask if you want to add it to the boot loader.  Enter Y to add it, then exit the command prompt and reboot your computer when you’re finished.

weldonlamAuthor Commented:
i tried typing cd c:\, nothing returns

I typed dir under "X:\Sources" which is the boot drive, then a list of files showing up.

Jackie ManCommented:
or is the windows installed in another drive, say d: ?

if you have no idea, reboot the computer, enter BIOS, do you see the HDD listed inside?

weldonlamAuthor Commented:
Windows was definitely installed on C drive and I can see HDD listed, thanks. When I clicked load drivers I can see drive "Acer" (which was C drive) on the drop down list.

try to run

bootrec /rebuildbcd

while you are at c:\

If Bootrec.exe does not find any missing Windows installations, you must remove the BCD store, and then you must re-create it.Do this by typing the following commands.

   
   Bcdedit /export C:\BCD_Backup - press ENTER
   
   ren c:\boot\bcd bcd.old -  ENTER
   
   Bootrec /rebuildbcd -  ENTER

when I reboot, it says Windows found problems and created something "longhorn" and save boot figure as bcd.bacokup.0001. Having said that, still no Windows found to select.

And when i do a search on directory of boot (C:\Boot). I now have three bcds  - BCD; BCD.Backup.0001; bcd.old

Have you dual boot with your laptop?

If yes, try to run Drive:\boot\Bootsect.exe /NT60 All

If no, Boot from vista setup dvd again... select install instead of repair and it will detect your drive, select cancel and go back to the repair section, your OS will show up now -> if os is detected, select startup repairs.
