installed mountain lion now computer will not allow me to enter just says restart

JUST GREAT! IT IS A 2011 BIG MAC. SCANNER, PRINTER, IPHONES(4), I HAVE A CALL SCHEDULED FOR TOMORROW. HOW DOES IT GET FIXED?

So nothing different when I do shift I come to a grey screen with a grey apple in the center and my two accounts underneath - each in it's own circle. One has my pic and one is a guest account. and when I try to enter my account it starts the skrim with words like I will hope to attach via pics I took on my iphone and sent to an email on my other Mac and then emailed back to me (cause I forgot I could do that from my iphone). It appears that there is no directory and when I hold down shift, command, and 'V' then I can see what is going on when I restart.

Please email me and I can send these pics to you as I have no way to adjust the size here, I guess.

NO! Well I don't know how to get them on here as all I can access is safari so I just moved them from my email to this reply page. I can't download them cause I have the 'guest' account limited to the size of the amount of downloads allowed and of course since I can't get to my own account on this **** computer. Last part says

I believe I must have spent 12 hours trying to figure this out-then I got my return call from Apple. Then took me 5 minutes to get it fixed! Recall I had this cycle of restart and could never access the blue apple screen-and I couldn't get a safe screen started! Well, when I pressed and held the shift key after pressing the power button, it opened and all is good. The Apple guy said something about linking the new installation to the old info. Amazing. But there was one prior step and I believe it was: press P and R and command alt at powering on-that did not take me into the system but just to the user account page where I could not access my account and computer only the guest account limited to Safari and nothing else on the system. So I want to remember that power on and shift and this may have been the time I also had to wait for 2 beeps before releasing. It's always difficult to remember the 'cure' as the excitement with success leaves one rejoicing and not mindful!

Thanks for the help
