I am trying for the first time to boot my Windows 8.1 laptop from the internal CD-DVD drive. I have a bootable CD in there, and yes, I do have the bios set with CDROM drive as first in the list to boot from. But when I try to boot from the CD, it won't boot, instead the computer gives me this message:
"ATAPI CDROM has been blocked by the current security policy."
(Its actually a DVD drive.) All it lets me do at that message is hit the Enter key to OK the message, and then it boots from the hard drive.
I have no idea where "security policy" settings are or what they are set for. What do I have to do to get this to boot?
This is a Gateway laptop, 2.2 MHz Intel Pentium processor, 4 GB RAM, 64 bit OS, with Windows 8.1 fully updated, and Windows Defender running and fully updated.
I have already looked everywhere I can find, but nothing seems to address this message or issue, as follows:
*I went to Help menu to look up "Security Policy." While the computer is giving me the message about "security policy," the Help menu has no idea what "security policy" is, it just comes up blank!
*I went to Control Panels/System and Security/Action Center/Change Windows Settings/Smart Screen/... All I found in there that might be involved is a setting to block anything downloaded from the Internet until I give administrator access. Well, the booting issue didn't allow me to give administrator access (yes, I am the administrator) when I tried to boot, I only could hit the enter key to OK. Nonetheless, I changed to: notify me but proceed (not a quote).
With that, I tried again, but it still would not boot from the CD, got the same message, so that setting is not it. I changed the setting back.
I see no other setting there that could be related by even a stretch. And the control panels should be dealing with the OS anyway, and this is happening while trying to boot from the OS on the CD, not the hard drive. That is, this is something in the root.
*I then went into bios area (UEFI Firmware) by sweeping in from the right and into Settings/Change PC settings ..., and found a tab in bios for Security. Looking there, there is a list of things, but it lets me access only "Supervisor Password." It was currently set as "clear," meaning no password. I left it as that -- surely I can't need a password just to boot from a CD, and the message I got in trying to boot from the CD did not allow me to enter a password.
Other settings in the Security tab were not accessible. The only ones they included that might be remotely related were:
*Password on Boot, which was set as no password. But again, the message I get with this issue does not ask for nor allow me to enter a password.
*Secure Boot Mode: Standard (It does not let me access to change that.)
Some others also were in the list that are not worth listing, not even vaguely related.
I then went into some other things elsewhere in the main settings called Startup Settings. The only thing in there that sounded the least bit vaguely related was "Enable boot logging." I punched F2 to go into that, but the machine instead restarted, and did not start from the CDROM, same message again. I went back to it, and it is still listed as Enable boot logging, does not instead say Disable - so I don't know if anything even got changed. I did not touch it again, left it as-is.
So, that's it. I've checked all the settings I know about. Nothing about this bit about "ATAPI CDROM has been blocked by current security policy."
I tested with two DVDs that I have booted from in the past on other Windows machines -- they also would not boot, but they did not give me that message.
I note, all three CDs/DVDs are being read fine by the DVD drive once the machine is booted in Windows 8.1 from the hard drive - so the issue is not that the DVD drive can't read the disks.
Where is this "security policy" set?! What do I need to do to get this to boot from the CD?

Hi,
So everything is back to normal... or at least working to your satisfaction ?
You seem to know more about manipulating your email than I do, but though I may be able to help by describing what my screen looks like !
I know how that kind of conversation goes... Not so much with Microsoft, but with my internet provider sometimes..
Hello Again...
If you ever need codecs for some reason, here is where I get mine... Directly from the writer... https://www.codecguide.com/download_kl.htm
This is for K-Lite Codec Pack... I use the "Basic" when needed...
The installer will install some crapware if you don't look closely before hitting "Next"...
It will allow you to Uncheck the extra stuff, but you need to look for closely...
In the forums, people even the past month were saying they had the problem, people from ever since win 10 came out have been saying so.
When I said I found it, I meant that Windows Media Player does not show up in the list of all applications. I think I found it in the Programs folder.
I know about default , etc. The issue isn't that the file doesn't open the player in WMP, it won't play once it does. I get a message, I forgot what it says and I'm on my Mac now. A number of the people in the forums got the same message, though.
I did install codecs after I wrote. I was thinking that might be it, and someone in the forums said to do that, and gave a link. And when I followed the link, it was codecs I have come across in past years that were highly recommended. It even noted that it included the proper ones for Win 10 64 bit, like my OS. (The was some suggestion that WMP might not work in the 64 bit version.)
I installed them. Then, when I opened the file, WMP,no longer got the message. But it would not play anyway. I uninstalled the codec pack.
I also found something in Control Panels, I think under Programs, that was there to fix issues in programs. I ran it three different ways to fix WMP. It still did not work after that was done. Pretty much was it did was set different things to default, but Ihad never changed any anyway, in fact, I can't even find settings in WMP.
My VLC Player also will not play any of the wmv files. People in the forums seemed to think that worked for them.
When you go to the MS page for downloading WMP, it has it for all OSs except Win 10. For Win 10, it simply says no downloaded, it is already included in Win 10! How stupid! So I can't even get another download of it to try a new install!
Oh, I have not had it working before, didn't even know I had WMP. I just brought these videos over from my Mac. They run fine on Mac out of Quicktime, but they won't run out of Quicktime,same version, on my Win 10 machine. I do have an extra codec pack installed on Mac for Quicktime, a thing called Perian. But Perian has now disbanded, and it never did have a set for Windows.
I could just convert them on Mac with Quicktime, but to do so, you have to use a third-part addition called Flip 4 Mac, which I have, but when I tried to use it, it does the conversion but puts a watermark over all, saying the trial period is over. I'm pretty sure that was never installed as trial! Im pretty sure it was a free app, but it does cost money now. The converters I have on Win 10 will not convert these files, I think because they are .wmv.
I'm just getting warmed up here. But you can already see this is WAY too much time and effort for native MS application to play a native MS format! Somebody needs to nuke MS! But I am not going to get into another 6-month effort to do MS's job for them, and they get the money.
Re your link to the sfc scan, yes, I saws that someplace, haven't done that one yet. Will do that after sending this, probably not get back to you tonight about it. You and I ran that once before for some reason.
Method 2 at that link is codec. I already tried what should have been a good codec pack, and it did include .wmv.
Then we have this guy talking about "unticking" some plugin. He gives Tools/plug ins/untick. A string. Where the **** is that? I find the problem with Windows people all the time,, don't fully explain so you can't do anything. What plugin? Is he saying that Intervideo thing? Windows people can't write clearly. When I get back tot he Windows machine, will see if that makes any sense. Where is Tools! Untick. I guess he is saying to turn that plug in off?
But that forum is Windows 7! Apparently there is widespread issue with this in Win 10 -- something unique to Win 10.
Lots of forums on this at MS. They all have 20 different solutions, and most people say they don't work, and all I've tried so far don't work. One in particular I tried was that bit about turning off and back on that WMP stuff in -- oh, where I already wrote about it.
Another guy turned on Direct X video acceleration. Good thing that guy didn't give an clue what that is, where it is, how to turn it off -- like I said above. know I had some kind of video acceleration on with the codec pack I loaded,, but that did not work.
Now seeing your third post --YES, Klite is the codec pack I got -- it didn't solve the problem. I used Regular, one step above Basic. Come to think of it, that said something about including a player, but I forget and never saw a player.
OK, results: Nothing worked.
I did find by right clicking I can get into some settings in WMP. I found Tools/Options/Plugins.
In there, there is nothing of the sort of what the guy said to "untick". Of course, he was talking of Win 7. I think it was supposed to be Intervideo Video Effect. There is no Internvieo anything in there. And in fact, it appears there are no plugins in there at all.
What is in there is a list under Category, and another short list under one of the things in Category labeled as Visualizations. That's it. But even if there was an Intervideo something in there, there is nothing that can be done with anything in that list, there is no "ticking" or "unticking" thing in there, no boxes to uncheck, no anything to do with the stuff in there. All that can be done is to add a plugin. Apparently, there are n plugins in there.
I then ran sfc /scannow, out of Command Prompt running as Administrator.
That ran, found nothing, said:
"... did not find and integrity violations."
I then tested WMP with a wmv file anyway, same, nothing different. The message I get is:
"Windows Media Player cannot play the file. The player might not support the file type or might not support the codec that was used to compress the file."
Like I said, when I installed the codec pack, that message did not appear -- but the video would not play anyway.
So, back to square one, with most everything recommended tried and failed, just like most other posted in the forums I've seen seem to say.
Re the message saying that the player might not supp[rot the codec used to compress the file, I would have no idea what was used as I didn't make the file, it was simply downloaded years ago.
Hi,
I just checked build 14393... I have no issues with Windows Media Player playing .WMV files that I have been able to find... Everything works... I even converted a .mpeg file to .wmv, and it worked..
The post about unplugging a "Plugin" is something concerning a specific program's functions... I just mentioned it in case you had some video editing software that might be interfering...
The post about DirectX acceleration in WMP is a WMP setting...
Open WMP and click on "Optimize" on the upper left, then "Options", then the Performance Tab.. You will see a check box in the list of options...
I'm just guessing here, but I don't have much else to offer since mine is working...
K-Lite's Player is kind of nice. I've used it before and it works well... After trying VLC, I thought I might like it better... It has options as to which controls appear on the player, which the K-Lite's Media Player Classic HD doesn't..
When I had the issue with .wmv files, I never did get them to work... It just got fixed in a newer build...
Something else I just thought of since you mentioned the Mac and QuickTime... Where did the files come from ? I don't really need to know, just suggesting that there may be a Permission or Licensing issue of some kind going on...
Do you know how to look through the security settings for the files to see if there may be something not right there ? Just right click on the file... then Properties, then Security Tab...
