I don't know how many times you've seen 0x0000007b when your Windows XP dies in a solemn blue. I've certainly seen my share. This article is only meant to discuss a specific condition that caused it: disk cloning. This is the time that you aren't careful enough to use a more capable tool, such as Acronis' TI with Universal Restore, so your newly imaged system falls flat on a different hard drive controller. This could also happen if you just physically attach a hard drive to a different computer that has a different HD controller. Microsoft has
a very good KB article
explaining how you can preempt (to a degree) this kind of problem BEFORE you clone or migrate.
So what if you weren't that careful? You forgot to take precautions, and you didn't use the right tool. Sometimes you don't want to, or simply unable to go back and try again (say your source machine is gone for good). All is not lost. You don't necessarily have to go through a lengthy repair installation, which will surely fix things in most cases.
. All you need to do is drop into Recovery Console and copy the
hive file under
directory to replace the one in
, which is used by the system to boot and run things.
I'm not entirely sure why that would help in this scenario. My theory is that the
, which was saved at install time, is a more "generic" version for things from HAL layer on down. Using it Windows XP would be able to survive more device structures and boot up. I can give one example this saved me time. I was doing P2V (physical to virtual) from an old TIB image (Acronis) to VMWare Server 2, using VMWare Converter 4. This trick let me get past 0x0000007b without repair installing XP.
How did 7b start happening? My article deals with cloning/moving hard drive to a dissimilar HD controller scenario. If that's not the cause for the 7b error, it won't really help.
That being said, if you are imaging with ANY tool, make sure the target PC has the same hardware controller and the source PC, or you are just asking for headaches. The 7b errors you see may be from incompatible hardware in your target machines.
