When i attempt to boot the computer, i get the message that the bootmgr is missing.  I do not have a recovery disc, but I do have a copy of windows 7.  I attempted to boot to the cd and Repair.  It attempts the repair but says that it has failed.  I tried to reinstall windows 7 from scratch, but after the computer restarts, i still get the bootmgr missing error.  I successfully installed Ubuntu 10.04, but cannot get windows to work.  Any suggestions?  I like Ubuntu and all, but I purchased this computer to be my windows machine.
