Vista - How to speed up Vista boot time?

I have a Lenovo T400 - T9400 (2.53 GHz C2D) - 4GB DDR3-1066 - Vista Business x64

How can I speed up my Vista boot time? Currently it takes between 75-85 seconds to boot into a usable state.
Once in Vista, my laptop is very fast, and I have no complaints.
I did a clean install of Vista.
I've already disabled many services and startup programs.
I did a bunch of little tweaks I found on different sites as well like disabling indexing, tmm, system restore.

The main thing that seems to be slowing the boot process is between the BIOS and login prompt.
There is a period of at least 15-20 seconds where the screen is black or barely doing anything before it jumps to login.

I tried going into the BIOS and making sure things are in order. I put the HD as the first boot device instead of CD (probably didn't save much time).

Is there something I can do to speed that time up?

Hello danskim, welcome to Vista forums!

It is a common misconception that disabling UAC has no effect.
In actuality it slows boot times considerably.

You may want to have a look at these also.

Hey BFK. Thanks for the links. I guess I should have been more explicit in what I have done. I did disable UAC and pretty much all the applicable stuff found in the tutorials.
The "issue" I have is that the black screen takes too long not really once Windows starts up.

I have a feeling there is little or nothing I can do to speed it up, but I was hoping someone had an answer.

*edit:
I just carefully read what you said.
So you're saying disabling UAC will slow down boot?

Yes, that is what folks are finding out ...
The OS was designed for it to be enabled!

Interesting,
I'll try enabling it and using the little vbs script to find out how long it takes.

try turning off windows sidebar also

Sidebar is off.
I tried enabling UAC again but it didn't make a difference.
I used the boot up timer and it was about the same.

I didn't see this one listed. It sped up my boot time by nearly 20 seconds.

Though this comes almost two years after the fact and probably of no benefit to anyone...

This delay is the transition when the OS is loading the video/display adapter driver(s) into a protected instance. After the OS completes the "green progress bars moving" thing, this complete black, where the hardware is disengaged completely, is proof it's happening, though that's not the reason it happens. In previous versions of Windows, a crash or failure of the video subsystem could (and almost always did) cause a system-wide crash. Vista first proves the system is working properly (a variety of items...i.e., checking the dirty bit, etc.), then if everything looks good, the green progress bars go away (which would not benefit, nor could the system have yet implemented a video driver in this "special" setup and the hardware is disengaged as the preliminary driver is unloaded and this new implementation is put into effect.

As they say in the vernacular of my area..."Them's the breaks." By far this is a fair trade-off for the drastic increase in system stability.

Informative. Thanks! Got links for the anal-retentive amongst us?
