Hi, I have been trying to install Ubuntu in my lappie..unfortunately the process got aborted during the boot loader installation. Now am trying to un install it completely and trying to install windows 7 on my PC. But i get error when windows 7 installation kit is trying to "Expand windows files." Someone please help. Tools in hand : Ubuntu live CD windows 7 boot CD I have no OS currently in my PC Previously installed one was windows 7 which has been completely formatted during my ubuntu installation. P.S : I dont want the data in other logical disks to be deleted. Guess there is some issue with bootmgr. Error says bootmgr missing.
