Pc hangs at 'verifying dmi pool data. . . '

Hello evgeryone. .! My p.c. Hangs up at verifying dmi pool data. . . . And not loading o.s.. . .

About my p.c. Conf:-
1. I have window 7 ultimate installed in c: drive. .
2. I have zotac motherboard
3. I have 500gb hard disk.
4. Ram is 2gb.
5. There is no floppy drive in my p.c.
6. Hp dvd writer
7. Nvidea 1gb graphic card.

Possible couse:-
i shrinked my c: drive and created a new volume using window 7 disk management. . .and than i restarted my p.c. And get this error. 'verifying dmi pool data. . .'
boot from cd. . .


What i have tried:-
1. I have tried to repair windows by inserting w-7 cd and selecting repair.
2. I have tried commands to repair master boot record. At the command prompt in windows repair option... The command i have tried are 'bootrec.exe/fixmbr'
which shows action successfull but it doesn't help to get out of my problem. .
Second command i used is 'bootrec.exe/fixboot'.
But it is also useless. .
3. I have restored my bios settings. . .
4. I plugged out and reinserted the hard disk sata cable. . .
5. In the pci option in bios setting i enabled the reset auto configration. . .
6. At last i installed new 7 window in c: drive. . .it was fine but when i shut down my p.c. And again rertarted got the same problem. . 'verifying dmi pool data. . . '
'boot from cd. . '
7. I have changed the priority of boot devices to default and all other possible combinations. . .

I have also same problem as above i.e i changed partition and got problem so to resolve the problem in boot option give the first priority to cd drive for boot and us any xp disk and then again restart the system and format it ....................
