On one of my machines (Dell Dimension 4550, 2.66Ghz, 1GB RAM), it takes
between 10 and 20 minutes to boot Vista. Almost all of this time is spent at
the phase where the little progress bar is displayed on a black screen with
"Microsoft Corporation" written beneath it. Once booted, performance is fine.

Any ideas what the problem might be, or suggestions for determining what
exactly is happening during this time?

Thanks,
Sean

To check if a particular program is slowing the machine when you switch on,
e.g. an antivirus program. Go to Control Panel Classic View Performance
Information and Tools Advanced Tools in the left pane. On this screen the
problem is sometimes shown.

If not, click View Performance Details in Event Log. You will notice that
events in the range 100-199 are boot events and can be followed by
double-clicking them, then clicking Event Log Online at the bottom.

I'm not MS, so just a friendly hint:

best guess to start would be a driver, at that point
Disconnect all peripherals, and try it that way, to see if one of them's the
cause.

The event log will have some information, if you can find it.
