Bootmgr is Missing - Vista Desktop

Need help on what to do next. Have been having HD problems and was attempting to 1) backup my bootloader settings and 2) create a bootable external media option using the EasyBCD tool.
However now whenever I boot system I get the message "bootmgr is missing" - so I am unable to bring up OS and also I noticed that my C: and D: drives are now reversed (C: is now my 10G recovery drive instead of OS drive.). I do have my original system CDs.

What should I do now? What should I have done in the first place to back things up in case of drive failure or corruption?

Still need some assistance Please -
