have you tried starting in safe mode, press f8 as computer starts up.
partmgr.sys is a windows file that affects partitions so if it is corrupted your computer may not be able to read the boot partition.
When you tried to reinstall windows from cd, did it boot to cd or continue on to the windows screen. If it did not boot with the disk, then go into system bios and change boot order to have cd drive ahead of hard drive.
