Hi Dinesh,

Good one. I would like to add few points here. Instead of trying RebuildBCD/Recreate as a first step, we could try startup repair at least 3 to 5 times which would search for problems and fix it.

Here are some commends

bootrec /RebuildBcd - Use this option when you must completely rebuild the BCD
bootrec /FixMbr - writes a Windows Vista-compatible MBR to the system partition
bootrec /FixBoot - writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista
Hi Dinesh,

If the automated startup repair doesn't do it - even after a few goes , as Prasath says,

I would try this first

bootrec /fixmbr

your dvdrom drive letter:\boot\bootsect.exe /nt60 all /force

del C:\boot\bcd

bootrec /rebuildbcd

Close cmd prompt, remove dvd, Reboot.

Fingers crossed.


your dvdrom drive letter: needs to be the letter as seen in WinRe, e.g. E: or F: etc.

I have the same problem with bootmgr is missing.
I just went through the steps listed.
Just at At the C:\Boot prompt, type ren c:\boot\bcd bcd.old and press <Enter>.
It states there is a duplicate file or file is not found.

OK, just tried that and it states.

Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.
Just has nothing changed.

I was able to reformat this once before when the hard drive was full of games with no problems. I even send a email to and they want a receipt to help in any way.
I would recommend you to do a clean install using Vista DVD. Sorry mate but some problems are unfixable withour reinstalation. :(
I was trying to do a clean installation.
Seems I have no drivers not able to do a clean installation of Vista.
The computer does not see any thing on the CD.
So now it's back to XP.
Edit note.
I just check my older computer and the Windows Vista says it will work on it.
So maybe after I get the newer computer running again on XP I will be able to install the Vista afterward.

Thanks anyhow.

Ive removed the 2 hardrives and tried booting it from just the cd/dvd drive it says operating system not found. I removed the cd drive and replaced it just to make sure its not the cd drive which is faulty but im getting the same problem wit the new drive so the cd drive is ok too :confused:

Can you ( not it ) go into Bios?

Startup and press F2 or Del, or whatever it says for "setup" on the screen.

No "i" cant go into bios as soon as it loads up i "del" it wont let me go into bios whereas it did before just goes straight onto "Bootmgr is missing" this is whats doing my head in :confused:
ive used hirens boot cd ran some diagnostics rebooted its letting me go into bios now so im getting somewhere :)
but in boot i have

boot priority order

1) usb optical drive *
2) internal optical drive
3) floppy disk drive
4) usb flash *
5) usb hard disk drive*
6) internal hard disk drive
7) network
If you have any external drives/devices connected - disconnect them.

Set the Hd you want to install on as the first boot device.

See if the installation continues.

If not,

Use the boot pop up menu selection on the startup screen ( e.g. press f11 or whatever for "boot menu" )

Arrow down to cdrom drive - put the dvd in , press enter.

It will probably ask to confirm - press enter again.

Hope it helps
i have no external devices connected are you on msn i think ive just deleted some raid settings in bios i have no idea about the bios settings :( please help me out
That is ok.

See if you can find the disk controller and set it to ATA - not AHCI.

You might just have donesomething like this :

Changed RAID ON to RAID AutoDetect / ATA

That should be fine.

Then try as per my previous post.
Bios are not all the same - you just need to look for something similar.

Where you saw those Raid settings is probably it.
