Hi all ... searching thru this forum, I found this thread. My HP laptop recently got this similar type of STOP failure. The full BSOD is: Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\DEFAULT or its log or alternate I am aware of these links: http://support.microsoft.com/kb/307545/en-us http://www.aade.com/XPhint/XPrecovery.htm My problem though is all I have are system recovery CD's. The OS is XP-Home (SP2). But I DO have access to an XP-Pro disc. Will that work? I just don't know if I will be able to use those instructions without an XP-Home installation CD. I have been Googling like mad searching on everything I can find about this error, including posts in other forums across the internet. Jaclaz's instructions above seem less tedious, although I've never tried that Avira NTFS4DOS though (nor UBCD4Win). At the moment of this writing, I am running a hard drive self test via the laptop's BIOS to be sure it's ok. If possible, my goal is to fully regain the current OS installation on the drive and not have to reinstall the OS, as well as keep the personal contents/files intact. Please help, anyone, thanks. UPDATE: Well, the harddrive self test passed including SMART (took 40 minutes). There's another thread in here similar to what's going on: http://www.msfn.org/board/windowssystem32c...amp;hl=c0000218 I forgot to say that Safe Mode or Last Known Config at startup doesn't work. It will always BSOD the same failure and then restart, until I manual shut off. The possible cause of this in the first place was my laptop overheating, thus corrupting memory and harddrive transfers.
