I am trying to diagnose the problems I've been having with boot-up on my machine. The system drive is an SSD, so it should be fairly quick. However there is one moment, right after the "Welcome" wheel where I get the mouse and a black screen for a very long time.

Now you can find the boot logs here: 95.42.32.75/z (BootCKCL.etl file, opens with windows performance toolkit)

I did several boot-ups and the results are always the same. In this particular one at about the 0:36 sec mark you'll notice this wide gap where nothing happens for about a minute.

It also doesn't seem to be related to any of the processes prior to the gap(tried to disable those). I have no idea what the bottleneck is and don't even know where to start.

P.S. I also tried the suggestion from one of the other threads here. There was a suggestion to run

xperf -start perf!GeneralProfiles.InBuffer && timeout -1 && xperf -stop perf!GeneralProfiles.InBuffer myTrace.etl

But that gave me an error message:

xperf: error: Failed to start profile: Cannot create a file when that file already exists. (0x800700b7).

Which I couldn't figure out how to fix.

So you gain no performance increase if you disabled ALL startup applications? –  Ramhound May 12 '13 at 9:43
    
I disabled the last three there. There's lots of them. Its unfeasible to try to disable all of those. The problem is how do I narrow it down and how do I find out where the bottleneck is. –  martixy May 12 '13 at 11:54
    
So, does a file with the name of myTrace.etl already exist, as the error message indicates? –  Oliver Salzburg May 12 '13 at 13:32
    
I created a new post you might find helpful superuser.com/questions/594625/… I'm still working on it though –  Oliver Salzburg May 12 '13 at 14:22
    
follow my guide here: msfn.org/board/index.php?showtopic=140247 to capture a boot trace. Also install the updates/hotfixes from here: msfn.org/board/index.php?showtopic=152622 and run the optimization if you use a HDD: msfn.org/board/index.php?showtopic=140262 –  magicandre1981 May 12 '13 at 15:03

Your boot is slow because of a long WinLogonInit phase:

When looking into the Generic Events of the WinLogonInit phase I saw that reconnecting the network drives takes most time:

So disable the network drives and reconnect them via

net use <driveletter>: \\Server\Share /persistent:no

on demand when you really need the network drives.

WOW... That actually worked brilliantly! Thank you so much. And at the same time somehow I'm not surprised that this exactly is the culprit. –  martixy May 14 '13 at 16:01
    
You're welcome. enjoy your fast booting Win7. –  magicandre1981 May 14 '13 at 17:46
