vista bootmgr compressed VISTA - need command prompt!

[auds6868]

I am at wit's end and even though my 8 year old bought his HP G60 with his own money, I am about to hurl it out the window as I wasn't "consulted" and would not have condoned this unfamiliar to me Vista O/S.

All I wanted to do was reset the computer/system to factory defaults.  He is gaming now a few years later with nothing important and seemed the quickest way to clean up the PC.  I create recovery disks, a NICE LITTLE PROCESS that took 3 entire days.  NO JOKE.  I had to place every few hours COLD PACKS under and on it because this thing from day one runs hotter then heck. 

So voila, it's done.  And reboots.  And I hope there is some other bored GEEK reading this because I can't find ONE POST on the entire Al Gore Internet that gets me to a command prompt without using install disks.  This HP shipped with no install o/s disks.  I created the recovery as a safety net, and it's starting over AGAIN and personally, I don't have 3 more days and hot pack maintenance in me before I just buy a new one.  PLEASE HELP.  It seems simple enough to get to a command prompt and uncompress something I never even intended to compress nor did in any keystroke of my imagination.

He is losing faith in his mother who he believes created MPLS....  got a network problem, I'm your gal.  Word won't load, call IT.  Windows XP has an issue, UNIX, learning Win7... but this Vista?  grrrrrr.  Where's the wine for my WHINE?

I guess I only said it in the subject. boot gets BOOMGR is compressed. Press Control Alt Del to restart. Tried the normal ways to boot and get into some start up, but seems I need a command prompt to uncompress...
