Wondering if someone can help me with the dreaded  Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): error which has recently cropped up on my Dell Dimension 3100.

Although old, this PC was running fine, no obvious sign of impending HDD failure.  The PC is running Windows XP Media Center Edition 2005.  There are just some music files that I would like to retrieve if poss (to save me having to rip all CDs again).  Once I have these I'll try and reinstall XP, or just junk the whole box.

I first went to microsoft support and thought this was the answer

Then I realised that, of course, Dell install OEM version of XP, so instead I looked at this instead.

Had to go into BIOS and get PC to boot from CD drive.  This went OK.

Then went to open the Repair Console.  And this is where I'm stuck.  The Recovery Console needs an Admin Password.  This was never set.  I've followed other tips here ie. using main windows password, admin, password, adminpassword, administrator (and even not entering anything 'blANK').  Each time it says that this is not valid.  So can't try any method from any forum /suppot site as I cannot get into Console.

Even went back into BIOS and set a password here (because one wasn't set at this level).  Still no joy

Does anyone know

a) What to do about password problem

b) If there is any really good post/page out there which you reckon has best explanation of how to resolve c0000218 error on an OEM PC.

Hoping there's a genius out there who can save 100 hours of re-ripping CDs!

Thanks
