u have a windows 7 disk ? go into bios set first boot device to cd yes press any key to go into the disk when promted on restart then go to repair and cmd promt to rebuild it
http://www.sevenforums.com/tutorials/104341-bootmgr-missing-fix.html
so u got to type in
bootrec /RebuildBcd
bootrec /FixMbr
bootrec /FixBoot
when completed remove the disk and restart
I cant do that... Because when I putted cd at first boot, then i save etc. then when bios finished loading, and I press any key, its not showing up anything, just the error BOOTMSG is missing, ctrl-alt-del to restart..
