Do you get any messages during boot after that-- such as that ScanDisk

That makes more sense than what ScanReg /Restore does! A lot more!
Congratulations to that ERUNT writer Lars Hederer! Thanks for checking
on that, Colorado. But, in...
http://www.larshederer.homepage.t-online.de/erunt/erunt.txt
ERUNT - The Emergency Recovery Utility NT
....I'm see the possibility that it created a .bak file(s) of the current
Registry just before doing a restore...
........Quote...................
ERDNT technical information
---------------------------
ERDNT knows two restoration modes.
....snip...
Note: In restoration mode "NT" backups of the current registry files
are automatically created, so that option is grayed out.
....snip...
The backups of the current registry files are placed in the same
location as the original and are given the extension ".bak".
........EOQ......................
So, do you see any .bak files in your Registry folders? That might hold
the Registry that was current just before you did the ERUNT restore-- IF
I read that right & if MS hasn't changed it since Hederer did that good
work. (That might be a little like RBbad.cab in Win98, but Win98 doesn't
use it when doing /Restore).
Also... I recall you said that ERUNT would update its latest backup, if
you ran it twice on the same day instead of deleting the oldest. Is it
possible that happened during the restore too? Was the size(s) any
different? But I guess that STILL would be preferable to what Win98
does!

There's a section in Hederer's docs that says you are on the right
track. You may have to do something to an .ini, though -- IF the XP
drive is a different letter -- before you run ERUNT, is all. That is
"file copy" mode.

OK, thanks. So, depending on how much space is set for it, there could
be more or less than 5 Restore Points-- but the same silly principle

You are right about the backup folder. Nevertheless, I've now got 6 (not
including RBbad.cab)...
C:\WINDOWS\SYSBCKUP>dir rb*.cab /od
Directory of C:\WINDOWS\SYSBCKUP
RBBAD CAB 1,575,664 09-19-07 5:56p rbbad.cab
RB005 CAB 1,602,739 06-14-08 6:50p rb005.cab
RB003 CAB 1,602,739 06-15-08 2:06p rb003.cab
RB004 CAB 1,602,711 06-16-08 6:24p rb004.cab
RB000 CAB 1,602,771 06-17-08 4:05p rb000.cab
RB001 CAB 1,602,738 06-18-08 5:58p rb001.cab
RB002 CAB 1,602,761 06-19-08 6:03p rb002.cab
By tomorrow, I'll have 7-- & I'll go do that test! Could be, although
the oldest won't show up in the /Restore operation, it might still be
the one that gets pushed out by it. It's just for academic reasons that
I want to know.
