dir/ah c:
dir/as c:
dir/ah d:
dir/as c:

this shows hidden stuff as well. Nothing found at all?

It should list the amount of files/folders. and th space available on disk. What amount of space is available?

Or run NOTEPAD from command prompt. then: file->open. Now you can explore the drives.

I don't exactly know what's happened but I think I've lost a load of data here, I AM sure there was a load more than this. Maybe all the repairs I've tried to do has knackered something..Is there any undelete utilities that I could use?

Startup repair doesn't delete that! Is C and D drive empty? What folders do you have in the root of C and D?

How many bytes available?

When booting from disk I get the message the file
File: \Boot\BCD Status 0XC0000098
Info: The windows boot configuration data file does not contain a valid OS Entry

No OS on DISK.

These messages were and are correct.

I ran the commands you specified.

the dir /ah C: shows 7 files at 5GB in size, 186GB free. dir /as C: shows the same
the dir /ah d: shows 0 files at 237GB free. dir /D: as shows the same

notepad shows the C: drive as 173GB free of 225GB yet the notepad files do not amount to 52GB...
the D drive may have been correct as this was not a heavily hit machine. I just don't know where my programs and everything else has went...it's as if something has wiped these files...rather strange..

I agree with your findings so it looks like toast eh?

I assume it's pointless trying any undelete utilities?

I wonder how to rebuild this as it was bought as a vista machine and came with an upgrade CD for win 7..

I have a copy of windows 7 but I don't know if the serial numbers from my machine would match these..

dir c:\ shows no folders/files?
So C and D are almost empty?
What is still on C and D .... old stuff?
