Bluescreen c000021a and windows7 pro

Hi,

i have a Windows 7 machine. Because of a HDD defect i got a bluescreen C000021a. It says that it was caused by a knowndll . I got a new disk and cloned everything to the new one. The cloning worked fine without any read-errors.
I tried to run repair-options from Installation-CD several times and also tried to run sfc /scannow in comand of repair-screen. It always says, that i should restart the computer.
Last known version in boot-menu doesn´t work neither. I can´t go to safe-mode -> same bluescreen.
There are no restoration-Points that i can use with in Repair-mode by starting with Win7-CD.

Is there anything like the good old Repair-Installation in xp ? Upgrade-Installation in Win7 only works if the system still starts...

I am trying to not install Windows with all programms and settings...

Any idea is welcome

Wait, you did not mention what happens when you try to start the system from clone HDD. What type of error?

exact the same bluescreen. thereust be a corrupt driver, dll or systemfile i think. but i dont know which file is responsible for this bluescreen

you can also run chkdsk from the dvd in command prompt

post the minidump, it may have more info; find it in windows\minidumps

Does it boot into Safe Mode?
I think your problem was not in failing HDD but in corrupt registry (virus attack?).

there was no dump or minidump-folder on the harddisk. I didn´t know where to get it from. So we gave up and installed a new OS.

well - if you had no minidump, you can check if the system is set to make one.
but if you don't post what you are missing, how can we know?
