BOOTMGR is missing - detailed problem report

[kush.impetus]

Hi All,

I have a single 500GB SATA HDD in my computer. (Rest of the specs are : 24x HP SATA DVD R/W, Intel C2D E7500 processor, Intel DG41RQI MoBo, Kingston 800 MHz 2GB RAM). When I first setup my hard-drive, I first installed "Windows 7 Home Premium 32-bit" on D: drive then "Windows 7 Ultimate 64-bit" on C: drive (some mis-communication between me and my brother).

The computer worked fine for about 2 months before I decided to "Compress drive to save disk space" on C: drive two days back. I issued the command and went away. On coming back I found my PC shut-down. When I powered it on again, it said

BOOTMGR is compressed.
Press Ctrl + Alt + Del to restart.

I searched Internet for solutions. Tried some of them. To no avail. Please note that I used a recovery CD already prepared for the process.

Then I used "System Restore" from the System Recovery Options from the Recovery CD. Restore process was successful, but then I started receiving another even agonizing message

BOOTMGR is missing.
Press Ctrl + Alt + Del to restart.

I again searched Internet, tried a few solutions, again to no use.

In despair, my bro installed Windows XP on a separate, unused partition backed up his stuff from D: drive. But I cannot do the same. I have to login into my Windows on C: drive to get my data back (mostly databases of the Web-sites and applications I am developing or have developed, which can be backed-up from the software concerned). I have backed up my codes though. Luckily I don't keep anything else on the Windows partition.

Sorry, getting personal. In the mean while I used the command "C:\bootrec /ScanOs" and "C:\bootrec /RebuildBcd". They say:

Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

When I run commands "C:\bootrec /FixBoot" and "C:\bootrec /FixMbr", they say

The operation completed successfully.

But I must say that when the recovery CD starts up initially (when it scans for installations of Windows), it does show that there are two installations of Windows on D: drive and C: drive in that order.

I have tried "expand bootmgr temp" sequence of commands. I have tried individually decompressing the compressing the folders that were decompressed. Everything again failed. (Notepad works from the Command Prompt in the "System Recovery Options" on the recovery CD. I was able to expand the compressed folders and take some backup from the Open or Save dialog box of the Notepad).

The "Startup Repair" option under "System Recovery Options" shows in its Log that no OS is installed".

Any ways here's the output of the command "C:\bcdedit" command:

EVEN WORSE, I can boot from the Win 7 DVD, it loads files and when I click "Install Windows", it says :
A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert it now.

When I click OK, it again shows up a dialog saying:
No device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK.

Now, I don't know where to find the drivers from and what drivers is it asking for.
So I cannot format my partition even if I want to.

My first booting device in BIOS is HDD, but changing it to my optical drive didn't make a difference.

I am still stuck in BOOTMGR is missing.

Any help is highly appreciated.

Repair MBR. To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:

1. Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type Bootrec.exe, and then press ENTER.

If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD. To do this, type the following commands at the Windows RE command prompt:

* bcdedit /export C:\BCD_Backup
* c:
* cd boot
* attrib bcd -s -h -r
* ren c:\boot\bcd bcd.old
* bootrec /RebuildBcd
