Digitally Signed Raid Drivers bypass [MSI, x64]

Question: Digitally Signed Raid Drivers bypass [MSI, x64]

Hello everyone,

I am trying to install windows and I have a MSI 890FXA-GD70 [product page] that is setup with a functioning RAID 0 configuration. My issue is when I get to the step where you select your hard drive, it doesn't show up.

So I click "Load Drivers" and select the x64 raid driver I got from MSI. It shows up, then I click next and then the error message comes up: "To continue installation, use the Load Driver option to install 32-bit and signed 64-bit drivers....etc"

I restarted and spammed f8 to get into advance startup options. I selected "Disable digital driver signing"

However that did not fix the problem.

Does anyone have any tips or a solution?

Preferred Solution: Digitally Signed Raid Drivers bypass [MSI, x64]

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

I'm trying to install a program, but I says I can't install an unsigned driver.

Driver: CPU Core Temperature Monitor
Service: Logitech CPU Core Tempurature (not a typo)

I've tried Disable Driver Signature Enforcement in my bios, and DDISABLE_INTEGRITY_CHECKS in cmd.

Neither works.

Answer:Need to bypass digitally signed driver requirement.

Go to Start Menu > Run and type the following command: bcdedit /set nointegritychecks ON
Restart the PC and install the unsigned driver
After installation go to Start Menu > Run and type the following command: bcdedit /set nointegritychecks OFF
Restart your PC

Windows Vista x64 decided to implement a 'security measure' by which all drivers must be 'digitally signed' to be allowed to install and run. I have a program which is compatible with Vista and x64 bit operating systems, however as its drivers are not digitally signed I cannot run it correctly - I recieve the message 'Windows requires a digitally signed driver' and access to the driver is blocked.

Is there a method of bypassing this?

Answer:'Windows requires a digitally signed driver' - How can I bypass this?

When you boot your system hit F8 and you can bypass it there. You will have to do this every boot. There are a couple applications out there that will do this for you but the names escape me right now.

Hi Guys, I did a search of my OS, and found some Drivers not digitally signed.Is that a problem,as my PC is functioning OK.Thanks for any advice.

Answer:Digitally Signed Drivers.

Hi D,
Your ok for the most part. A driver that lacks a valid digital signature, or that was altered after it was signed, can't be installed on x64-based versions of Windows. As a result, you will see this message ( Windows cannot install this driver ) if you are running an x64-based version of Windows.

The only other time (I think) may be if you updat a driver. again you may get that can't install it error. You can visit the device manufacturer's support website to obtain a digitally signed driver for your device.

I have had to reinstall Windows 7 64-bit edition, and when I go to install PCWizard or Everest Home Edition, I keep getting an error about drivers not being digitally signed, and Windows will not install them. Before I reinstalled Windows 7, I had both of these programs running just fine. Is there anyway I can change the fact that Windows 7 will let me install those drivers?

Answer:Digitally Signed Drivers?

The only way for 64 bit versions of Vista or Win7 to work without digitally signed drivers is to start them up using F8 to get teh Advanced Startup and disable the Digitally Signed Driver service.

If you had them working before did you make sure all your drivers now are current?

Answer:Windows Drivers Digitally Signed

The fact that the drivers are not certified by Microsoft merely means that the vendor did not submit them for testing and pay the bill to do so.

Many perfectly good drivers are not certified -- so do not worry about that unless you actually have problems with the hardware.

Having said that there are two ways you can restore the old drivers in XP. One is to go to the Device in question in the Device Manager, open its properties dialog (double click it) and select "rollback driver" on the driver tab. Windows XP backs these up automatically when you make a change.

The second is to use System Restore to return to a prior date.

Why is everyone saying Vista 64-bit won't install unsigned drivers? I installed the latest beta driver from nvidia and Vista warned that it was unsigned but gave me an option to install anyway.

Am I missing something/misinterpretting this or was this only the case in the Beta/RC verisons of Vista and everyone keeps bringing it up (kind of like requiring UAC for changing backgrounds; people still say Vista does it)?

Answer:Digitally signed drivers required under Vista 64-bit?

Short answer: The effects of FUD.

Long answer: The truth is, it was never stated on any official documents that Vista wouldn't accept unsigned drivers. The real mechanism is how Vista handles such drivers, in that the permission level changes, but that's such a 'behind the scenes' object that some ppl though it cooler to just say, "NOEZ, the sky is falling!".

Hi all, I've been running the RC for around 3 months now and love it. I didn't have any issues when I installed it. I added the drivers for my raid card when the select partition option came up, it installed them and away it went. Now that I'm trying to install the retail version it insists that my drivers are unsigned and that's the end of that. I've tried using the repair system work around to get the drivers loaded; but that option says that the drivers don't match my installed hardware. I'm using the exact same driver I used for the RC, on the same thumb drive in fact. Plus, Promise says they're signed. I know there isn't a problem with the raid card because I'm on the system now. Anybody have any ideas?

Answer:Win7 x64 won't recognize my raid drivers as signed

Well, I got it about an hour after my post so I figured I'd report back in case anyone else has a Promise FastTrak 2650 and runs into the same issue. Even though I hadn't done it while installing the RC, I unplugged everything except for my keyboard and mouse. I switched over to a VGA cable as well. This time instead of pointing the install to the 64 bit drivers I just hit ok and let it look for its self. It loaded the 32 bit drivers, proceeded with the install and then somehow reconfigured its self with the proper drivers once Windows was up and running. As soon as I hit windows update it downloaded the very same x64 driver I was trying to install from my thumb drive and installed it just fine. So now its up and running perfectly. I thought letting it load a 32 bit driver would have hosed the install; but apparently I was wrong.

"Not digitally signed" means Microsoft have not tested this driver and verified it to be compatible with Win XP.  This does not mean it will not work, you should click on the "continue anyway" to install your print driver.  If this is a concern you should check the HP web site for newer driver tested by MS.Kim

So I just upgrade to Vista x64 and 4GB of memory (courtesy of OCZ).

However, when installing the x64 version of MagicDisc/MagicISO I get the following error:

Can I get around this?

Answer:Required Digitally Signed Driver?

Uhmmm... yes, you can by pressing F8 at boot time and choosing to ignore the warnings about unsigned drivers, but you have to do it each and every time you boot. There is a way to permanently disable that driver signing requirement but I'm leery to give out the info anymore since it hosed a few people's machines recently.

It wasn't my fault that they chose to continue using shitty old drivers, but they blamed me for the mistake they made anyway.

Vista x64 is a more secure and stable OS than the 32 bit version, and that's one of the primary reasons why: the driver signing requirement. Disabling it or 'getting around it' will more than likely end up causing you issues at some point.

Google can find the specific method to disable the signing requirement permanently, or a search here might find it since it's been posted about 3 times over the past 4 months or so.

Good luck, either way...

Answer:[SOLVED] System Files Not Digitally Signed

Hi TomGab and welcome to TSf !

You don't have to worry about system files that are not digitally signed, it only means microsoft hasn't run extensive tests on them. The file owner (nvidia for most of your nvxxx.dll files for instance) will have tested them to make sure they would work fine with XP so you shouldn't have any problem.

Hi all, hoping this is the right subforum

I built a HTPC a few years ago and it had suited my needs fine. Relevant parts used are:
i3-3225 CPU,Scythe Big Shuriken 2 RevB,Asus P8-H77 Pro,2 x 4GB G.Skill Ares DDR3 1600 RAM,Samsung 830 Series 64Gb SSD (OS HDD),WD Cavier Green 2TB (Media HDD),

I tried to upgrade to Windows 10 but kept receiving errors, such as the partition was not GPT (0xc000021a). The one error that happens every time I tried to upgrade or install Windows 10 was winload.exe was not digitally signed. I wiped the drive, reformatted it as NTFS, converted to GPT and installed W10 from blank and still had the same winload.exe error. Right now I have put W7 Ultimate 64bit back on and am installing all the windows updates.

My question is, does anyone know why I keep get a winload.exe not digitally signed error? I have downloaded the W10 upgrade files numerous times, redownloaded the media creation tool, set clean boot, even tried downloading the upgrade and creating a usb drive with it from a different PC but same error.

Is there perhaps some upgrades that I should make my HTPC?

A signed driver is not necessary in Windows. It is an extra security layer, as drivers can become corrupt by malware. If you obtained the driver from a trusted source (like the device manufacturer's website), you can go ahead and tell Windows to install it.

From what I know if these progams are running and they aren't digitally signed then they are most likely a form of a virus. I can manually find the official conhost.exe from windows/system32 and run it, that creates a separate instance of it running, making two, the official and the supposed virus. Neither of the supposed virus executables do not open any properties when I right click and select properties from the task manager, which is another red flag. I ran a fully updated malwarebytes scan and an avast scan outside of windows and had no returns of an infection. I could not find the location of the virus executables and I am looking for some help.

I recently purchased a new pc that came with win vista 64 bit premium home installed. I am now reloading all my old programs and I keep getting ?windows requires a digitally signed driver" error message. I also can't seem to play my old movie files, all of which played fine when I had Win XP. Apparently Vista does not want me to make my own decisions, so I am wondering how I might go about disabling all this extra secure vista crap. Can I go into Control panel and disable the BitLocker Drive Encryption? Or do I need uninstall 64bit and install the Vista 32 bit? Would that be a smooth transition? Would all my stuff work again if I had the less securitized 32bit Vista? Thanks for any help you may provide.

Answer:windows requires digitally signed driver

Welcome to the Vista forums

1) You don't want to disable UAC (User Account Control) as it does a lot to protect your computer from various malware. If you really feel the urge to turn it off, then you can in control panel in the User Account section. Once turned off, you'll get the red shield in the bottom right saying it's disabled. Disable security warnings by opening security centre and going to "change how security centre warns me" or something and choose the "no warnings" option.

2) Just download the Vista codec pack (just Google it and you should find it) and DivX and you should have no problems watching videos.

3) You can install unsigned drivers on Vista 64 bit, do this by running an elevated command prompt (right click on command prompt in Start menu and click "run as administrator".

Type this and press enter bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

When you reboot, you should be able to install unsigned drivers.
Also, I looked on the HP website for your computer, and it has 6GB RAM, so going to Vista 32bit would only allow you to use about 3.5GB RAM. I also saw it only has an Nvidia 6150e onboard graphic card. Are you using this? As if you upgraded this to a graphic card, you'd notice better performance on Vista as well.

I have x220 with Windows 7 Pro 64 bit. Device manager shows under Storage Controllers "Ricoh PCIe SDXC/MMC host controller," but there is a yellow triangle with "!" and a Device Status Code 52 message "Windows cannot verify the digital signature for the drivers required for this device." I checked in C:\Drivers\WIN\Multicard and found two *.cat files--which, I understand, are required to confirm digital signature. Each of them ( and has a signed and valid certificate! So what is going on? Will the card reader work? Is there something wrong with how Windows 7 is treating the Ricoh driver, which I downloaded from the Lenovo site? Why should I be getting this grief?


Go to Solution.

Answer:Ricoh card reader driver-not digitally signed?

Perhaps the driver is damaged?
Try deleting the Ricoh PCIe SDXC/MMC host controller from the Device Manager and then restarting the computer in order to let the Device Manager re-detect it and re-install the device drivers.  Does that solve the problem?

I'm at my wits end. Anyone who can help would be my hero.

Acer 5253 laptop, Win7 Home Premium 64bit SP1, AMD C-50.

Trying to use a USB mouse. I have 3 logitech mice. None work because hidclass.sys and hidusb.sys are not digitally signed. If I f8 and disable driver signing enforcement, all 3 mice work, so I'm pretty certain that's the issue.

Tried "Update Driver" via device manager. Windows determined that I already had the best driver and wouldn't do anything.

Logitech does not furnish drivers for Win7. They rely on the native drivers.

Acer does not furnish mouse drivers. They refer you to the manufacturer of the mouse.

Tried copying the files in question from a 64bit machine that showed them to be digitally signed. Renamed the ones on my machine and pasted the ones from the "good" machine. Resolved nothing.

chkdsk /r found problems and repaired them. Didn't help.

sfc /scannow found problems that it could not resolve. Looked in CBS.log and found no references to either of the sys files in question. No resolution.

System Restore only had one restore point, and it was from 2 days ago. Problem was already noticed by then. I suspect that it's been this way since I purchased the laptop a couple of months ago anyway, but if there had been a restore point back at the very beginning, I'd have tried that.

Hi all, Following device:ThinkPad E531Graphics: Intel HD 4000System: Win7 Pro Following problem:1) Approx. 2 month ago a windows update caused a problem with the hdmi at my laptop. There was no connection to the TV possible anymore (I tried the TV, the cable and the hdmi device already).2) I installed a new driver (origin: Lenovo support page). Result: Windows messages that the driver is not digitally signed...Hence, the device "vga save" was set. What I've already tried, everything as admin:1) look for older drivers: Got only one and it didn't work2) Tried to install a driver directly from Intel: Didn't work3) Tried to disable the signing (GPEdit.msc -  code signature ...).

Here the cmd said the command is not known.6) Tried to install the drivers (Intel and Lenovo) after setting the "TESTSIGNING" off (BCDEdit).

But why Windows does not accept them?Is the available update to Win10 an option? Generally: Failure F40 (the failure is 40 cm in front of the monitor) is not excluded  Thank you very much in advance.Regards,Stefan

Hi. I am installing a Windows 7 64 bit OS on a refurbished HP Pavilion p6331p AMD Athlon II x4 with a wiped hard drive. The hardrive is a Seagate 750 GB Barracuda.

I've tried all combinations in the BIOS (IDE RAID AHCI). Nothing is working so I'm not sure where to go from here.

Answer:No signed drivers message

Hello oldsgold, welcome to Seven Forums!

When you say "a wiped hard drive" what method did you use to wipe it?

If you didn't use the clean all method listed in Option One of this tutorial at the link below, boot the Windows 7 DVD to diskpart and give it a go, it'll take close to 3 hours to complete.

Then use the outline in Option Two #2 of the same tutorial to create and activate a single 100GB partition to do the installation to; try AHCI first then IDE if necessary.

SSD / HDD : Optimize for Windows Reinstallation

DISKPART : At PC Startup

You shouldn't need to add any drivers at all as Windows 7 is all most driver complete and be sure to post back with any further questions you may have and to keep us informed.

Hello Peoplearenuts Welcome to the Forums  
I don't want to say this but you didn't need to buy win8.1 to get 10; you can install windows 10 for free if you have 7.
But since you bought it​​ lets work on it.

So the first thing to do is not to do a clean install; you want to upgrade the PC threw the desktop
it will automatically assign the HDD based on what your upgrading.
Please don't fell bad about this we all make mistakes; believe me I have made some big ones

I don't want help installing my antivirus, I want them to post signed drivers!If you manage to find a signed driver, or get an actual response out of Lenovo, please post back!I'd heard such good things about Lenovo, but if I cannot get this sorted by the end of the week, I will be returning my PC and buying another brand.

I'm trying to install Windows 7 on a computer I just built. I know all the parts are compatible.During installation, when it looks for a storage device, it says it gives me this message:No signed device drivers were found. Make sure that the installation media contains the correct drivers, and then click ok.I downloaded all the drivers from the motherboard manufacturer's website onto a flash drive and tried again. Still no luck. Then I tried a CD; it still refuses to find the drivers.Does anybody know why it's doing this? Or how I can disable driver signing before I install it?

Answer:Windows 7 can't find signed drivers?

If you are running the windows 7 intaller on another windows like xp or Vista that is the problem.Try booting from the cd rom.if the problem continue make sure that your hd is visible in the BIOS, and enable the option IDE MODE, SATA MODE or similar.Regards,esvom.

I have seen some of the threads listed but none have been able to get my nephew's laptop working again. It is a Toshiba Satellite Pro L450D. His hard drive got corrupted and we've lost everything. I am now trying to load windows 7 64 bit on to a brand new hard drive. I keep getting 'No Drives were found. Click load Driver to provide a mass storage driver for installation'.
I then press the "Load Driver" and get up 'To install the Device driver needed to access your hard drive, insert the installation media containing the driver files and then click OK.'
When I browse to find the drivers I've downloaded from Toshiba direct on my flash drive, I get "No signed drivers were found. Make sure that the installation media contains the correct drivers and then click OK'
This is as far as I can go because I do not know how or where to get "signed drivers".
If someone is able to help a silver surfer to complete the installation it would be much appreciated. Thank you

Since I made the Move to 64-bit a while back, Every once in a while, I would run into a Problem where I needed to Install Driver that was Un-Signed.

As A Security measure in the 64-bit Versions of Vista/7, All Drivers must come with a Secure Digital Signature.

This is not a large problem anymore with the fact that Most Drivers are Signed nowadays. But Older Hardware Drivers tend not to be Signed.

There is a Simple way around this Block.

Open the Command Prompt in Admin Mode (Type "CMD" into the Start Menu and press "Ctrl+Shift+Enter")
Enter this Command: bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
Now when you Re-Boot, You should be able to Install those Pesky Un-Signed Drivers.

Hope it helped. (if so, +Rep is one of the best ways to thank)

Hi Benjamin,

We have a tutorial section for guides like this if you would like this thread moved there?

You can also install unsigned drivers by either self-signing the certificate or installing the one it came with, if it contained any digital certificate

I have an ABIT AT7-MAX2 (VIA KT400-8235) computer with AMD Athlon XP 2.08Ghz running IE7 SP3. I just did a clean install a couple days ago. I only now noticed that my 2nd Hard Drive does not appear (like it used to) when I look at My Computer. However, if I use the Search feature it will search in both my C: Drive and also my E: Drive (the E: Drive is the 2nd HD). Other than using the Search feature - I have no access to the E Drive. (I use the E: Drive for my pictures.) I did not change any BIOS settings when I did the clean install. The two HDs were (and still are) setup as RAID 0. So, I'm confused why the 2nd drive isn't seen on my OS. Is the reason because I [somehow] lost my RAID Controller drivers when doing the clean install? Or is there something I must do in XP to add the E Drive so I can see, and use it, on my PC?

As far as the missing drivers - when I look at the Device Manager there are two YELLOW question marks (?) under "Other Devices". These two line items are both RAID Controllers. Looking at the Details, these two (2) RAID Controllers (under Other Devices) are missing their drivers. I'm hoping this is easy to fix...

Is this why I can't see the E: Drive on my PC? Does anyone have any idea what drivers I need for them? I assume the drivers be on the ABIT CD, right? Should I try the ABIT CD and hope it's easy to download the drivers I need?

Here is what one of the RAID Controllers' ID says: PCI\VEN_1106&DEV... Read more

Make sure you don't have any of the following updates installed


These all reinforce driver integrity checks.

I had to rebuild my W500 after my Hitachi 500 started giving read errors.  This means downloading a lot of drivers from the Lenovo site directly.  Several aren't signed, which causes some annoyingly difficult to fix errors. switchable Graphics driver (7vd617ww.exe)  driver version 8.792.5.0The artifact is that attempting to launch the catalyst control center results in a "" error. The Conexant 20561 SmartAudio HD driver version This is loaded with system update 4 and does not have a verifiable signature either.  The "properties" dialog reads: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

So I am doing a fresh install of Win7 64bit on a machine I build a while back. It has a Rampage III Extreme with Marvell SATA III controller. I installed the drivers just fine when I build the machine. Now it won't let me install the SATA 6.0Gb/s drivers. I get the, "Please install 32bit, or signed 64bit drivers. . . " crap. I tried the drivers off the CD, from Asus's website, and Marvell. No dice. Any ideas?

Edit: FWIW I am installing off of a USB drive and there are two drives in RAID-1.

Answer:Please install 32bit, or signed 64bit drivers.

Are the drivers unsigned?

i have an MSI 915P/G motherboard with two maxtor 160GB HDD's as a RAID 1 array. my mobo has an onboard RAID controller. the system worked. wanted to reinstall xp, so i performed [email protected] killdisk on my c: partition. now windows doesn't see my RAID array. i installed an additional seagate SATA HD and was able to install XP on it. device manager displays a yellow question mark by my RAID controller, but if i install drivers for the RAID my computer fails to boot and goes to windows 'safe mode or last known good OS' screen. safe mode just keeps rebooting, last known good takes me back to RAID controller driver problems.
any ideas of how to get my data off the d: partition of my maxtor drives would be great.

Toshiba is really the best notebook I saw! I had to change my HD because of a hardware failure (disk dead); before this I made a "recovery disk" from Toshiba system. I thought I would have just to boot from this DVD to reinstall all. BIG ERROR!

So I booted fro this DVD, process goes on (about one hour, already a great delay!), BUT a few drivers, especially the wireless one, cannot be installed! I get a message that "Drivers must be signed and so cannot be installed", and am kindly invited to get the "right drivers"!

On the website Toshiba there is no "right driver", I got those that are supposed to be for me, but always receive the same Windows message.

So what to do?!! This "recovery disk" does not even recover the correct drivers? What a great joke !!!! And of course the computer was sold without any DVD!

OS: Win 7, 64 bits "home", with legal license.

Hello, I've read a few of the other posts but haven't been able to get it to work on mine yet. I'm getting the "no signed drivers were found" error when trying to install windows 7 64 bit on my new build. I don't have an old one to format the hard drive and partition it on. So my question is can I build a partition outside of the install or inside of the install? When I switch to ACHI(AHCI) which every one it is, and I go into advanced installation it gives me the option for new partition but there are 0 MB available to do this with. I've put my comp specs into my profile. Thanks in advance for your help.

P.S. When my old desktop crashed I had a working laptop so I has been years since I've had a 2nd desktop to work with.

Answer:No signed drivers were found on fresh install new build.

Put the Dvd in the computer when you get to the screen where it asks you where you want to install Windows . Hold down Shift and press F10 . You will then have a command prompt Window and type in these commands

Press < ENTER > after every command







Then back in the Where to install Windows click on Refresh and you should see

Disk 0 Partition 1: Windows 7 C:

Highlight that and click on next .

If you don't want to use the entire hard drive you could type in CREATE PARTITION PRIMARY SIZE=51200 that will create a 50GB partition

This is going to be difficult since I am the middle man here, but here it goes.

A few months ago I sent my friend a Windows 7 DVD for his new computer that he built, and everything went fine. Earlier this week he was building another one, using the same HDD and disk and he kept getting errors that are still unresolved. He formatted his old HDD and still didnt work, and also got a new 320 GB hdd and same problems. He cant even get Ubuntu to install. ive searched for a few hours and couldn't find a similar problem or solution. The exact error message is "No signed drivers were found. Make sure that the installation media contains all the correct drivers and then click ok." Sometimes he got an error 0x8030001, not quite sure what he did to get that. Anybody have any idea about what to do?

Well then. How bout that? I should have just gotten Vista 32bit. I just tried to install a program on Vista and Vista turned up it's nose.
Sorry Dwayne, but I refuse to install this driver. It hasn't been signed!

And I replied with, You fool, this is a legit program, there's nothing wrong with it. It will work just fine. Install it.

And vista says to me, Well I don't want to.

Then I replied with, do it anyway. Your my computer, my operating system, you do what I say.

And then Vista laughed.

Is there a work around that I can set up to get Vista to install these "unsigned drivers"?

Answer:Requires signed drivers... program may not work properly

you have to run Vista with the option to allow for unsigned drivers - reboot, hit F8 repeatedly until you get the Vista menu, and select (I beleive) Allow Vista to use unsigned drivers.

Be warned, though that this is something you'll have to do *every time* you boot.
