So I REBOOTED my laptop after a few updates installed.

I was presented with a black screen and text saying

"BOOTMGR is MISSING
 Press Ctrl+Alt+Del to reboot."

And this process was practically a loop...
I'm downloading a Vista recovery ISO right now.
But once I rebuild the BCD Store to fix the BOOTMGR.exe from the Vista recovery disc (my PREFERRED method of repair), will I lose all my data on my HDD??More than 1 OS on this machine ? ?

At any rate once you have DLoaded the RC and succesfully created a bootable cd with it boot to the CD...
At the COMMAND prompt type fixboot and hit Enter.
Remove the CD and re-boot.

If no joy-joy repeat the procedurs except this time type in fixmbr and hit Enter...
Again remove the CD and re-boot...Im having the exact same problem on my DELL Inspiron laptop. Where can i get the right things to fix it ?Take a look at the guide over here for help. http://www.howtogeek.com/howto/windows-vista/fixing-bootmgr-is-missing-error-while-trying-to-boot-windows-vista/

If you don't have a Windows Restore Disk, you can CREATE one with a friend's computer. http://windows.microsoft.com/en-US/windows7/Create-a-system-repair-disc

Ignore the below unless you're familiar with Linux.

If you have a Linux Live CD lying around (unlikely), then you can restore the Windows mgr by entering these commands in the terminal.

Code: [Select]sudo apt-get install ms-sys
ms-sys --mbr /dev/sda

Make sure you know which hard drive you're performing this on. If you only have one storage device plugged in, it's most likely /dev/sda. You can check with GParted.
