Black Screen Boot Delay

Would really appreciate a reply from the forum staff about this, doesn't seems to be much support for users here from them.

Cheers,

2 things you can try :

Go into Win8 Settings> Update and Recovery > Advanced Start Up > then use the Start Repair option.

If that doesn't help, on your Bitdefender GUI > bottom right > " help and support" choose the option to create a support ticket, that will generate a support package for the techs.

They can then go through the system with you.

There could be a conflict with '360 Internet Security' if is was not properly uninstalled leaving some rermants around in file form or in the Windows Registry. You might want to do a search of your computer's file system and make sure there are no files left from 360. Also check your Processes once the computer starts and make sure there no Processes running from 360. Finally you could check the Windows Registry though better to use the 360 Internet Security uninstall tool than manually fiddle with the registry.

Ah, I thought that till I read the post again.

What Banzi is saying is, that with Bitdefender installed there is/was a lengthy delay at boot. Therefore BD was removed and 360 installed.

With 360 there is no boot delay on his system

I have seen some very odd behaviour on Win8/8.1 and Bitdefender at boot time. On my laptop at some system starts the boot was painfully slow, at other times boot was quite fast, but nothing like the speed Win8 quick start should show.

Uninstall BD and use a different AV and the Win8 quick start is finished in seconds. It looks like BD is affecting the hybrid shutdown.

Black screen boot delay has been a problem on many peoples computers and it doesn't only effect Windows 8. There is a lot of discussion on these forums about it. I first installed BD TS on my Win 8 laptop and have never seen the problem (although I have changed it to Win 8 Security now). However on my Win 7 desktop I consistently have 10+ seconds prior to the Welcome screen of black screen on boot, which doesn't happen with another AV.

I will wait and see if the next version of BD fixes it as I have no problems with a slight boot delay.

I have BD W8 Security running on three Intel W8.1.1 computers and BDIS running on a AMD W7-SP1 x64 computer

Every once in a while a get the black/grey (I guess it depends on the monitor) delay but usually on my oldest Intel which is a i5-2320. This computer orignally came with W7 and I got to W8.1.1 by upgrading and updating. Thing is that it is not all the time and I never checked to see if I could eliminate it by removing BD W8 Security. Not worth the hassle since I don't restart every day and only restart when I am done using the computer for the day.

I have noticed that the W7-SP1 with BDIS will take slightly different times to restart but I don't recall seeing a black screen on that computer. Could be because I don't use that computer very much so again its no big deal. I will try a restart now and see what happens. Shutting down took 25 seeconds and the restart was on the Dell logo for about 20 seconds then the Window logo window for 20 seconds then a black sreen with the cursor for about 20 seconds or a little under 90 seconds from clicking restart until I got the the Windows login screen. However, I did not see a black sreen only with nothing showing. Keep in mind this is an AMD computer with an Athlon 2X that is about four years old or maybe a bit older. I am also running MBAM 2.X Pro, EMET 5.0 TP along with several other security programs so given all that I think the restart time is acceptable, but that is just me

Thanks for the replies folks & sorry for the delay in replying, was away from home for a couple of days.

Bitdefender AV+ 2014 x64 was the only security app other than Spyware Blaster & the MVPS hosts file on a clean install of Win 8.1 Pro x64, got all the windows updates including update 1 before any apps were installed, After installing BD & getting latest updates & rebooting the delay was there, basically the PC rebooted & windows boot screen shows then that vanishes then black screen for long period of time (shortest was 43 seconds, longest was 2 minutes & 10 seconds) then the login screen appears, sometimes I got the please wait screen with the spinning dots & they were freezing then the login screen shows. When the desktop had loaded BD also seemed to be causing a delay in that as well, ObjectDock took a while to show & startup apps loaded slowly as well & also the desktop icons would refresh.

After a few reboots with the delay between 43 seconds & up to 1 minute & 20 seconds, I then checked event viewer & saw the messages that are in my previous posts, I then unistalled BD through programs & features & rebooted & then ran the new BD uninstall tool & rebooted again, installed BD again & got the updates & rebooted & the delays were back again, uninstalled BD, rebooted & used BD removal tool & rebooted & then installed 360 Internet security & there was no boot delay.

Event viewer basically shows that the "The Bitdefender Virus Shield service did not respond on starting." On Win7 x64 I had no boot delays & had BD running fine with Comodo firewall 5.10 & even MBAM pro 1.75

If I have time later today I will make a Reflect free backup of Win 8.1 x64 & then remove 360 & clean up & then reinstall BD & film what is happening, I did try BD's built in diag support but that always crashed.

I would prefer to use BD as I paid for it & still have about 110 days left on my license, I could go back to my Win7 backup but after customising & tweaking Win 8.1 it kind of growing on me.

Cheers,

Banzi.

Just a thought. You could contact BD and see if that will let you switch your remaining license days to BD W8 Security at no cost. I have used it for about 16 months originally with W8 and now W8.1.1. I use it on three W8.1.1 computers and have had no problems with it all and best of all no malware issues. I have had to do a repair a couple of times over the 16 months but that is it.

I too have issues with boot delay (on Win 7 Ultimate x64) and I see that there is that "black screen" with a couple of seconds prior the Welcome screen. This was on both BD IS 2014 and BD AV 2014 Plus.

When I tried BD AV 2014 Plus alongside Comodo Firewall ver7 and with Shadow Defender / Keyscrambler Pro disabled as start-up entries, the fastest I got was 50 sec to 1min 14sec. It never did went down beyond the 50sec.

Tried with a different AV (AviraFree) and boot time was only 26sec with Shadow Defender and KeyscramblerPro as startup entries.

With BD IS 2014 my boot time is from 54sec to 1min 04sec. The attached autoruns>Logon image shows that Shadow Defender is not present(uninstalled) and KeyscramblerPro has been disabled and process stopped. Actually support said to uninstall SD(I was reluctant at first because there was not any issue with the previous setup but I did uninstall it to see if the boot time speed will improve). It did not.

When I had a different security setup on this partition (Emsisoft IS + Shadow Defender + KeyscramblerPro all as start-up entries alongside iReboot.exe) my boot time was only 31-34sec.

I made a new partition from a system image backup (using Acronis) of the existing partition with BD IS 2014. Recovered that to a vacant partition and installed BD AV 2014 Plus alongside Comodo Firewall ver7. The black screen is the same and the boot time is around the same area of 1 min+.

I do not know if the Wallet service is part causing this delay or is a factor in the slow boot speed I get but this observation is only when BD product is installed. With another AV or internet suite there is no issue with blackscreen delay and slow boot time.

These are the images with the boot speed time I have with my default partition (Emsisoft IS) and my second partition( EAM + CIS7).

It seems the [black screen] delay is caused, amongst others, to the Master Boot Record scan that is performed prior to loading Windows. Bitdefender is trying to reduce the time it takes to integrate itself with the Windows services that start prior to the loading screen.

Hopefully this improvement will show up when the 2015 version is released.

I made a 10 day graph of my boot speed on my last reply. From there I will be moving on to another setup.

Have you guys thought of giving the 2015 Beta a try? I now only see a "visual" black screen of between 5 - 10 seconds and my boot has improved quite a bit.

I know this post is old but thought I would add some info/update anyway.

Installed Bitdefender AV Plus 2015 edition on a fresh build of Windows 7 - 32bit.

I now have a blank screen at boot up for 200 seconds. Albeit a slower PC but before installing Bitdefender no noticeable delay or black screen.

So, if your hoping 2015 has fixed this issue, it is still there if not worse.

ROFL , today i repair my installed BitDefener Total Security 2014 and now i have the 10 secs delay ... Anything to do ?

Sorry to see that. You can check out if this article works of your balck screen problem.
