Upgrade Never Completed ( 2 Hours Freezed On The Final Step)?

i was working on w7 ultimate x64 (i had xp 32 before, but due a hardware upgrade i wanted to try an x64 os) when an automatic upgrade from windows poped up(i was pretty sure i disabled the option before, but.. whatever). The thing is the upgrade never completed ( 2 hours freezed on the final step) and i had to reboot(i know, my mistake).from here, i tryed to boot but i did not sucess. the first issue apeared when i turned on the pc, and the boot recovery windows poped up, to check if there waserrors on the HDD. but wont never ever complete (6 or 7 hours running)i started to search on the web for a solution and i found a bunch of similar cases (a failed update and a failed boot recovery) but no clear solutions.never the less, the moest of the cases pointed at the same spot: "the bootmgr file" and i started to try a few steps posted on forums.first of all, i put the w7 dvd instalation and accesed to the console prompt.i followed these steps to delete and reinstall the bootmgr, or at least, that was what the post told me [CODE]well, i am about of exploding or jumping from a roof... seriously, i have some unfinished works to deliver in the begining of the week and i will not succes if ineed to blow up my D: and reinstall.
