win vista recovery disk

#1
HI,
Purchased a Lenove G550 laptop last month, had problem with Bootmgr. Downloaded the vista recovery program from your site and ran it atleast thrice by clicking the REPAIR WINDOWS option but still its showing me the same msg "Bootmgr is missing".Went to D drive via command prompt and ran system_repair.exe and now its showing me Win Vista (Recovered) in the REPAIR WINDOWS but thats it.Have ran out of ideas....please advice as my laptop is unusable presently and my Vendor is saying that any software problem is chargeable.
