I have dualboot desktop pc with win7 and windows 8.1


Problem is in win 8.1 boot:

PC starts booting normal, then comes OS selection menu, (i select win 8.1) then about 5 seconds is win 8.1 logo loading screen and then comes about 5 sec black screen and then comes 5 sec welcome screen. How to repair this?


Before was same problem in win 7, then i updated video drivers and it was ok then, but not now.

I have zonealarm free and panda free antivirus all updated. windows is also updated.


I put some screenshots, maybe someone can give me some directions what to look.

I just in case uninstalled zonealarm, but still same problem.

These are fresh clean installs.





Is the black screen before winlogon.exe?

I have very beginner level with wpa and xperf.


Thank you. :mellow:

You have two antivirus programs running.  You should only have one antivirus install on a computer at a time.  I would suggest that you uninstall of these.


IMPORTANT NOTE: Using more than one anti-virus program is not advisable. Why? The primary concern with doing so is due to Windows resource management and significant conflicts that can arise especially when they are running in real-time protection mode simultaneously. Even if one of them is disabled for use as a stand-alone on demand scanner, it can affect the other and cause conflicts. Anti-virus software components insert themselves deep into the operating systems core where they install kernel mode drivers that load at boot-up regardless of whether real-time protection is enabled or not. Thus, using multiple anti-virus solutions can result in kernel mode conflicts causing system instability, catastrophic crashes, slow performance and waste vital system resources. When actively running in the background while connected to the Internet, each anti-virus may try to update their definition databases at the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.

I have this problem too.Once I fixed it by using an MS theme instead of my user theme mod.I accidentally lost my background while using Teamviewer & once I re-applied it,the black screen delayed start prob emerged again.Stop using UXStyle themes & also try a different theme.**It used to be worse,I only got a black screen & Windows Metro UI wouldn't work--while I used my theme mod--also Welcome screen wouldn't appear & I had no way of signing-in to my Outlook account (had to wait many hours till it reloaded properly.)Anyway this was fixed (once the password was removed) by Signing-out & back in using StartIsBack+.The worst thing that happened to me was when some article suggested deleting SoftwareDistribution folder & then Metro UI would fail completely--luckily I ran SFC (I have no Win 8.1 disks) & some other Fixit/diagnostics apps.Luckily it's resolved now & I have to be extra-cautious.Win 8.1 is nothing but trouble.Linux [Sabayon & Red Hat 9 (now Fedora 15)] is worse!!

UxStyle manipulates system files and the Software Distribution folder is a system folder.  If you interfere with system files and folders and something goes wrong, who is to blame?
