I think u r doing start up repair via os dvd correct . u get this error now : Bootmgr is missing or compressed . To fix that issue follow this simple steps : copy bootmgr file in other working system (windows hidden file) location c: drive .(pendrive)
Use linux or hirean boot cd to see hdd . Paste Bootmgr in c: .that's it .
If Bootmgr is compressed . Uncompress c: via hirean boot cd .
