Windows Stuck at Boot (windows update stops at 75%)

Question

I performed a windows update and also changed some windows components (uninstalled sidebar gadgets, uninstalled fax software, etc.). During the obligatory boot, Windows stopped at 75% without any error message. After an hour, I restarted the PC only to see that it is stuck at 75% again. I don't know if this bug will be fixed in the next version. I have uploaded the pending.xml from the winsxs folder for more details: http://dl.dropbox.com/u/58053593/pending.xml

Answer 1

can you also upload the complete folder C:\Windows\logs\CBS and the file "C:\Windows\servicing\Sessions\Sessions.xml"?

Answer 2

I have uploaded the files: http://dl.dropbox.com/u/58053593/files.zip (good thing I can mount a vhd in Win7)

Also,  I want to mention that I tried the "refresh your PC" option, which did nothing (some error).

Hello Paul_X,

What version of the operating system are you attempting to install?
It seems that you do not have enough disk space on your C: drive to install.

The minimum requirements for Windows Developer Preview are as follows:

System Requirements of Windows Developer Preview:

1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)
DirectX 9 graphics device with WDDM 1.0 or higher driver
Taking advantage of touch input requires a screen that supports multi-touch
To run Metro style Apps, you need a screen resolution of 1024 X 768 or greater

According to yout CBS log:
2012-01-16 01:16:36, Info                  CBS    Free disk space check on C:. Available: 16004MB

which is 15.63 GB.

So if you are installing for the 32-it or 64-bit version, you do not have enough disk space which would be why your install is failing.

Let me know your status.

Thanks,

I can't see that it stops at 75%. In 2011 you installed updates and they work fine.

Mount the VHD under Windows 7 and open a CMD prompt with admin rights (right click on cmd.exe and select "Run as admin") and type this:

DISM /image:F:\ /cleanup-image /revertpendingactions

(replace F with the latter of the mounted VHD)

This reverts the pending operations. Unmount the VHD and save the changes and now try to boot Windows 8.

@Marilyn

I installed the developer preview including the dev tools (64-bit) back in 2011 and have been using it to develop apps. I have this issue while doing a windows update. This is _not_ related to free disk space (I sized the vhd to 40 GB) or other minimum requirements.

Answer 6

@Andre Thanks for your answer. This is strange that the logs say different. Before reading your answer I deleted the pending.xml and can boot into the windows developers preview.

However, the OS is behaving very strage (freezes, slow, unresponsive). I guess, this is due to my setup. This is what I did - with the note to not do it :)

- installed the windows developer preview into a vhd; boot from vhd -> worked great

- used the color calibration to adjust the screen gamma -> broke the XAML editor in VS Express. Anybody knows how to "reset" the color calibration?

- installed the latest intel drivers to get HW accel. -> UI much more responsive

- uninstalled VS express and installed the VS Dev Preview (ultimate) -> works great (XAML editor still broken)

- installed the synaptics touchpad drivers (this could be the reason)

- uninstalled some windows components (fax, sidebar gadgets, etc.)

- reboot

- hangs in windows update. Using the troubleshooting (in the boot options) the "refresh" option failed

I will now start from the beginning since I need a working dev environment :-/

Answer 7

Hi Paul-X,

try booting in from your WDP install media. On the Install box that opens, choose trouble-shooting options given on the lower left of the box, instead of Install. Proceed on, trying the various methods of repair options given. Hope that helps.
