Give me the ProcMon log and a new xbootgmr trace with this command:

xbootmgr -trace boot -traceFlags BASE+LATENCY+DISK_IO_INIT+DISPATCHER+FILE_IO+FILE_IO_INIT+FILENAME+POWER+Registry -stackwalk profile+CSwitch+ReadyThread+DiskReadInit+DiskWriteInit+RegQueryKey+RegOpenKey+RegCloseKey+RegSetInformation+RegSetValue+RegDeleteValue+RegQueryValue -resultPath C:\TEMP

With this command I capture wait and registry data.

Did it! Do you need the ETL file?

sure. Compress it as 7z to reduce the size, upload it and send me the link via PM.

Hello,

I PM'ed you the etl file. Thank you so much!

the trace is too large. I can't open it correctly. But from what I see, the issue is large CPU usage for a long time. Use this command:

xbootmgr -trace boot -traceFlags BASE+LATENCY+DISPATCHER+FILE_IO+FILENAME+POWER -stackwalk profile+CSwitch+ReadyThread -resultPath C:\TEMP

Also use the 8.1 SDK. You used the 8.0 SDK!!!!!!

Hello,

I sent you another one. Unfortunately it's still quite large. I can open it with Performance Analyzer on my system so please let me know if you'd like me to take a screen shot or anything.

yeah, still too large. Give my a trace with this command:

xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -stackwalk profile

My Vaio vpc-yb1s1e/s has a cursor lag issue, although I disabled unnecessary services and removed/reinstalled graphic drivers,

You're really my last hope.

Thank you.

what do you mean with cursor issue?

The largest issue with your boot is, that your HDD is very busy during boot.

There is a huge delay when I move my cursor in different points of the screen.

Can you suggest me a way to know the exact cause of this HDD loading?

your TOSHIBA MK3265GSXN is a slow 5400rpm drive. You can't expect miracles from such a slow drive. Get an SSD. You can find good ones with 200GB for 100€.

I have a Server 2012 R2 system booting from an Intel SSD.  Since installing Chrome, I noticed a 15 second hang during boot every time.  Uninstalling Chrome doesn't change the behavior and I don't really think Chrome is the issue.

 

I followed the steps in this posting no how to trace the boot times and the results do NOT show this 15 second hang.  However, I isolated it down to the OSLoader.  The problem does NOT show up in the ETL file.  For example, osLoaderDuration only shows 877 as the time:

 

    <timing bootDoneViaExplorer="15107" bootDoneViaPostBoot="-1" osLoaderDuration="877"
            postBootRequiredIdleTime="10000" postBootDisturbance="9223372011747"
            pnpBootStartStartTime="37" pnpBootStartEndTime="854" pnpBootStartDuration="817"
            pnpSystemStartStartTime="1013" pnpSystemStartEndTime="1381" pnpSystemStartDuration="368">

 

So what I did during boot is press <F8> to get to the boot options.  I think put the cursor over the enable boot logging option and at exactly 14:19:00, I pressed <Enter>.  When I did that, there was very brief disk activity and then no disk activity for ~15 seconds.  Then the boot continued as normal.  What's interesting is looking at ntblog.txt as you see here:

 

 5 18 2014 14:19:16.499
BOOTLOG_LOADED \SystemRoot\system32\ntoskrnl.exe

 

So there was an ~15-16 second delay from when I told Windows to boot to when the boot log started logging activity.  Any idea what is causing this ~15 second hang?  Since ETL doesn't show the problem, how can I figure out what Windows is doing during this time?  THANKS!!!
 

_{Regarding my Post #327, I think I stumbled onto something.  I use Hyper-V on this system and I have XDC and Virtualization Technology both enabled in the BIOS.  If I disable either one, this 15 second pre osloader hang goes away.  I only get this 15 second "freeze" if both XDC and Virtualization Technology are enabled.  I checked with HP and my system has the last BIOS available for the system.}

 

_{Any ideas?  Thanks.}

I don't use Hyper-V so I've never seen this.

Hi Andre, thanks for the Tutorial.

 

A couple of days ago my Zenbook UX32VD (Win 8) started to take 4 - 6 Minutes to boot up for no reason I'm aware of.

 

The full boot summary is here: http://www42.zippyshare.com/v/98947187/file.html .

 

From what I can tell the culprit is the SATA AHCI Controller which takes over 4 Minutes to load (the Driver is up-to-date). I wasn't sure if it's a good idea to disable it for testing so I didn't.

 

<phase name="bootStart" startTime="29" endTime="246530" duration="246501">

        <pnpObject name="PCI\VEN_8086+DEV_1E03+SUBSYS_15071043+REV_04\3+11583659+2+FA" type="Device" activity="Start"

                   startTime="2515" endTime="242870" duration="240356" prePendTime="240356" description="Intel® 7 Series Chipset Family SATA AHCI Controller" friendlyName=""/>

 

Any help to understand or even solve the problem would be greatly appreciated.
