W7 Upgrade error - winload.exe is not digitally signed

Question: W7 Upgrade error - winload.exe is not digitally signed

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?

Preferred Solution: W7 Upgrade error - winload.exe is not digitally signed

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.)

Answer: W7 Upgrade error - winload.exe is not digitally signed

I'm looking at my DirectX Diagnostic tool and it says for a few things
"The file ati2dvag.dll is not digitally signed" under Video, and "The file RtkHDAud.sys is not digitally signed" under sound 1 and 2. is this a serious problem? it might help solve why I've had a few crashes when playing games maybe? If anyone can help I will be very grateful, especially by telling me how to get these "signed"

Answer:Not Digitally signed?

I know very little about this kind of stuff but I think it just means it's a driver that hasn't been registered with Microsoft, or something along those lines. I don't believe it affects the operation of the thing.

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?

Am trying to install HP Deskjet 630c printer and it keeps telling me this driver is not digitally signed. I just put Windows xp on the computer. What does this mean and can I get help? I am not very computer literate and any help would greatly appreciated. Many thanks Paula.

Answer:driver is not digitally signed

"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

Dear All,
A vendor website sporadically release's MSI's which are digitally signed (plugins to run the content). These are required for the website to function.
Users are more in number so we can't manually install the MSI and time is a constraint.
Packaging / Repackaging is not a quick solution
App-locker doesn't bypass UAC, AUTO IT didn't help, Manifest and shim are only for Exe's.
We are looking for a solution where in since these are digitally signed MSI's Users should be able to install them automatically without being asked for the credentials.

Most of you know by now I hope that Vista requires it's drivers to be digitally signed by Microsoft. Is there a way to bypass this when the final product is released or do you think MS will back down due to public rage?

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.

G'day. I'm trying to install my old VisionPLus DVB-T card into a Windows 7 O/S box and it won't recognise any of the old drivers. When I try to install the TwinHan Digital tv software, Windows can't/ won't install them.

I've downloaded and tried the latest (DigitalTV 3.4 Build 19-02_20090212) and windows comes up with "Driver not found". I've tried to install in compatability mode but still no good.

When installing the above, it identifies my card as “PCI CX-87A with MCU DVB-S/-C/-T/ATSC card”.

The one written for Vista would be my choice, probably not one for W7 yet, may never be.

Looks like MS ha removed a way to disable unsigned drivers protection in Vista64, so probably is the same for 7
The issue is known to affect PeerGuardian, TV tuner cards, Gigabit Ethernet adapters, CD/DVD-ROM/RW drives, and many other devices.Click to expand...

Looks like unsigned drivers are a no go for x64 Vista and Windows 7, well there are some workarounds in the article above, sounds like a hassle.

Good evening,

I just reinstalled XP on a friends machine that was pooched. It is a Dell DIM4400. Everything is working except for the sound card. It is a built in sound card. When the computer boots up the new hardware wizard comes up asking for a driver for a realtek AC97 Audio device. I have tried everything I can to install the driver but each time I try I get an error that the driver is not digitally signed and it won't install. If I try in safe mode it installs but I get a blue screen upon startup and have to reboot. I do not have the orignial Dell cd but I have tried every driver from the Dell site that should work on this model of computer. I have updated the chip set drivers on the motherboard etc. I just can't get this sound card to work. Any advice??

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...

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.

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!".

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.

Windows suggests to uninstall the program or device that uses this driver and check the publishers support site to get a digitally signed driver.

They say too much knowledge can be a dangerous thing. I'm probably living proof of that.. someone told me how to run a Microsoft diagnostic that shows which system files do not contain digital signatures. According to the scan, 35 of my files are suspect. Should I be concerned about this? I religiously scan for viruses, spyware and rootkits using three different apps for each.

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.

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'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.

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.

So I've had Windows 7 x64 for a while; all fine and dandy. I decided to give the new Win 8 Developer Preview a go (x64)- I installed it to a separate partition on the same HD as Win7- all went smooth as expected. I've spent the past day or 2 playing around with Win8- but decide I want to boot back into 7. So Win8's installed the lovely new Graphic Bootloader and has both OS's listed (again as expected). I select Win7 and it reboots and attempts to load from the Win7 partition (can't fault it) until it instantly loads the whole recovery / repair failsafe of Win7. That's unable to detect any issues with boot, however upon exiting that I'm thrown back to the graphic bootloader of Win8, and the circle continues. So I realised that I still have recoverymode enabled on my Win7 entry in the BCD; I go ahead and disable it to be greeted with a message explaining that winload.exe is no digitally signed (when trying to boot Win7). If I try to access advanced options to temporarily disable driver signing I'm taken to the new bootloader which gives me no such options for Win7.

So I'm unable to boot back into 7. I can still get on the Dev Preview of 8 (in fact that's where I am right now), but I'm a little confused; why is Win7 now spitting out this error on boot? Surely the new Win8 bootloader isn't too dissimilar to manage booting Win7 correctly?

Did alot of googleing and most of the solutions have access to the Install disk which I dont have. cant find anyone with the same exact problem as I have.

I am downloading Knoppix now to see if that will boot up, will update my post when i get it downloaded and burned to disk.

This is really pissing me off, any help greatly apreceated.

Answer:annoying Winload.exe error

It's a virus, plain and simple.

Use Knoppix or Gparted or whatever to totally and completely remove all traces of partitions on the drive, build a new partition table and if possible, use a Windows 98 CD to boot from, get to the "Safe Mode Command Prompt" and do fdisk /mbr to wipe out the MBR with a completely generic one.

Then start over, but not until that MBR has been wiped clean. The partition table stuff with Gparted is one thing, but that has no effect on the MBR which needs to be wiped, and fdisk can do it with that /mbr switch.

You can also get a bootable floppy image and write it to a USB stick if needed from - doesn't matter how you do it, you just need to get that MBR cleaned out or this error will not go away.

If you can't get a floppy image, etc, you can use this "hacked" version of the HP USB Disk Storage Format Tool I've been using for several years now - don't freak out at the "hacked" reference. What I mean by that is that this one has DOS files internally - if you choose that option, when it creates the USB stick it'll have some of the files necessary (including fdisk) already on the stick ready to go; you don't have to supply MS-DOS files to put on the stick, if that makes sense.

You can get this utility here: (195KB, Zip file, .exe inside)

It's tested, used, abused, tested again, then tested again and it has no virus - it ... Read more

I've been trying at it for a couple days now but nothing seems to be working!

My friend is trying to install Windows 8 pro 64bit over his Windows 7 32bit. I know you can't 'upgrade' so we went with the custom/clean install. We backed up any files he needed and used the Windows USB boot tool and loaded the iso file into a bootable usb. Went through the install process and about 10mins in, the PC restarts itself.

I then get an error saying...

Your PC needs to be repaired.
The digital signature for this file couldn't be verified.
File: \Windows\system32\winload.exe
Error code: 0xc0000428

It then gives you some options at the bottom to choose another OS or startup settings, but choosing those options just flickers the screen and does nothing. I've tried reinstalling and the same thing occurs. I've also tried other methods such as copying the bootmgr file from the USB onto the boot drive to replace the older bootmgr, but that didn't work either.

Any ideas??? I'm not sure I can get back it back W7 since everything on the HD is already wiped (don't care about the data obviously, just want to get W8 to work...)

Answer:0xc0000428 winload.exe error

If you're getting that error, it would indicate your initial ISO used to create the USB was/is corrupt and not an actual good copy, or the file copy to USB failed at some point (if you're sure the Win8 ISO that you downloaded from Microsoft has the same MD5 sum and CRC hash as the file on Microsoft's servers).

I currently have Win 7 Ultimate x64 on my rig, and have acquired Win 8 Pro x64. I've tried too many times now using the Win 7 USB/DVD Tool to create both a USB and DVD to boot and install Win 8. Whatever media I'm using at the time boots into installation just fine, but after the first initial restart during installation, I get hit with the missing winload.exe error (0xc0000428) and flashing screens when I tap any corresponding keys. I have to go back to reinstalling my Win 7. I've tried upgrading over 7, formatting to a clean install, not formatting to a clean install, used both USB and DVD media.. I just don't even know what to do anymore. Should I just try some burning software at a really slow speed and see if that helps? If so, what brand? (I can never seem to find any bootable image files for making the disc bootable, so if you could point me in the right direction...) Also, how in the world do I go about fixing this error? Thanks so much in advance.

Answer:I'm Really Getting Frustrated (winload.exe error) Please Help...

That error indicates that Windows cannot verify the signature used to sign that file, and treats the source as untrusted (and thus won't boot). This would indicate that however you acquired your Windows 8 media, the media is corrupt in some way (either you downloaded it and the CRC / MD5 doesn't match, or the file copy to the USB key is failing). I'd start by checking the ISO you originally received with the MD5 sums for working media to see if they match.

(I forget what's that processed when it turned off). Suddenly the power supply of my netbook went off. It's caused by my home electricity.

Then I turned on my computer, when i select to boot from windows 7. Then appeared text like this :

Info:Windows cant verify the digital signature for this file.

It says, I must press the F8, when I press F8, it appeared again...

My netbook is dual-boot, Windows 7 Ultimate and Windows 8 Build 7955. I look some website, tells me to repair it with EasyBCD. I tried it using Windows 8, but when the installer of EasyBCD and install dotnetfx.exe (Is it Microsoft .NET Framework 2.0?) it's cancelled and roll back automatically. It looks like the dotnetfx doesn't compatible with Windows 8 Build 7955.

Is there any other way to fix it? Can you give me a detailed solution?

Thanks. (P.S. : I don't have the DVD of Windows 7 because I lost it sorry for my bad english)

Answer:Error 0x0000428 - winload.exe

Windows 8 is not official yet.

But what you can do is download BCD Editor - Windows 7 / Vista.
It has a "Dual-boot Repair" utility.
Start it and click on "Automatic Repair". Confirm.
This will repair the Windows 7 boot environment files:
bootmgr - Windows boot manager, the BCD and boot records(MBR and PBR).
and make Windows 7 boot by default.

If the entry for Windows 8 is missing when in booted in Windows 7 run
Visual BCD Editor, click on pop-up menu "Create missing Windows loaders"
and confirm. This will scan your system and add an loader entry for Windows 8
or any other installed Windows 7/Vista/XP or VHD.

I've been working on a friend's HP Pavillon dv6000, trying to reinstall Vista after a crash. The computer didn't come with a disk, instead it had a recovery partition that was never accessed to make the requisite set of Vista discs in case there was ever a problem so I was forced to order one for HP.

Upon setting up from the ordered HP disc I received the winload missing prompt. I've downloaded and used a generic Vista recovery disc from an online site in order to get a command prompt, tried the fix suggested so many times by jenae but received the error that says An error occurred while attempting to reference the specified entry. The system cannot find the file specified.

I never see another step offered in any of the threads that I've searched out in this forum and other ones. I'm not entirely positive that there's not something wrong with the HD itself as it's not my computer. The initial problem was described to me as "my daughter installed a java update and the computer then crashed". I do believe I'm beyond that point as I've twice removed the HD from its chassis and reformatted it from my own computer which runs Vista HP SP2. (and yes, while I had it out I backed up the drive, so that the information therein was saved)

Thoughts, suggestions?

Hey, im working on restoring a friends laptop as it had a winload error (0xc00000e9), nothing would fix it so I decided to completely wipe the drive and do a clean install of vista, the HDD reformatted and installed properly and when I boot the laptop it still get a winload error but now with a different error code, cant quite remember what the code was as I am currently trying to reinstall the OS again, think it was ending in 0FE.

I've never came across winload problems like this before, generally one of the many fixes out there work or a clean install fixes it, if I boot into safe mode the screen just goes black at log in and stays like that, any ideas why it still occurs on a fresh install?

I know theres a lot out there about winload issues but each one seems to be unique every time,

Normally I wouldn't ask this however it is a bit of a weird error because of how it came about. Right I had Windows 8 installed but my hard drive on my laptop failed and so I had to steal the harddrive from my other laptop with a broken screen and it already had Windows 7 running on it but I thought I'd install Ubuntu while I make a Windows 7 USB and boot into it to re-install.

So now I have Ubuntu and I hate it personally and I'm trying to boot into Windows 7 to install it via the USB and I have followed many tutorials on how to make a bootable USB. Anyway when it boots up it comes to a 'Windows Boot Manager' screen and says:

File: \windows\system32\boot\winload.exe
Status: 0xc0000001
Info: The selected entry could not be loaded because the application is missing or corrupt

Is it because I'm booting from a USB? The reason I'm doing that is because I didn't receive a recovery disk.

Answer:Winload.exe error while booting 0xc0000001

Try creating the flash drive again, only this time using Universal USB Installer – Easy as 1 2 3.

You have to create an .iso from your Win 7 install DVD. If you do not have a Windows 7 installation DVD, you can download a legal copy with SP1 integrated from here: Official Windows 7 SP1 ISO from Digital River.
Make sure you get the same version you have, Home Premium, Pro or Ultimate and 32 or 64 bit. Note that Basic or Starter is not available.

In the first drop down box, scroll all the way to the bottom and select Windows 7.
In the 2nd box, point to your .iso file.
In the 3rd select your flash drive.
Click Create and off you go. In a little while you'll have a good, bootable Windows 7 install flash drive.

Sorry to ask this if it has been asked a million times. Have hunted around on the forums here did not find my exact problem.

I have a computer with 7 installed, and followed the guide on these forums to set up a partition with XP. I installed EasyBCD, and get the initial black screen that allows me to select which system I want to boot with. However, when I select the XP partition, it tells me that it can't find winload.exe and to insert my installation disc. All of this being done, upon restarting I get the same error. No problems whatsoever running 7.

I'm a complete noob to dual-booting, so please go easy...ask me any additional info or screenshots that I may not have thought of mentioning that might help you help me lol. Thanks in advance.

Answer:Dual boot & and XP winload error

Did you install EasyBCD 2.0 to XP in order to Add Win7 to the Dual Boot menu?

Make sure you are using version 2.0. If not install it in Win7 then Edit Boot Menu to remove XP entry. Next use Add tab to add XP back, accept offered boot files, autocompletes, Save, Restart.

If this fails, post back a screenshot of your full Disk management drive map using Snipping Tool in Start menu, attach file using paper clip in Reply box.

brand new ASUS N750JK notebook with Windows 8.1 OEM pre-loaded (by an official ASUS shop) on a Samsung 840 SSD, while the HDD is still empty (the notebook contains two drive bays).

At start, everything worked fine. I was able to log on to Windows and take a look.
Then, after a reboot, I went to the UEFI BIOS to check out settings and all. I did not save any changes though. Then I tried to reboot, and I got this error 225 message about windows\system32\winload.efi not found.

Tried F8, but does nothing. Tried F9 at POST (should launch the ASUS recovery image in the hidden restore partition) but F9 does nothing. Even disabling Fastboot in BIOS, no joy. All I get is the error screen a few moments after I turn the machine on.

I have no installation/support/recovery media from ASUS, and did not have the time to create my own in the short time before the system broke down.

I tried a Windows setup disk I got from a Toshiba notebook with Win8.1. Tried different Windows repair/recovery options, but nothing works. Good news is I can access the Windows file system on the drive. I tried recoverydrive.exe from command line, but it says it can't find some files it needs.

Answer:Error 225 at boot, cannot find Winload.efi

Eventually I solved it. I used a rescue CD from Macrium Reflect free edition, based on Win PE 5.0. After booting, I used the Fix Windows BCD feature. At first I thought I did it all wrong, as I got a pop-up message about something done with Windows 7, while I have 8.1.
When I tried to boot the PC, I got a new error message "0000001", instead of 225. I was almost giving up, then I tried the F8 key (which didn't work in the error 225 window) and finally Windows was up again! I tried a Safe Mode boot, then Normal mode, and it seems all-right-
So far the good news. The bad news is I still can't get Windows to use manufacturer's system recovery image on drive. Maybe it depends on the re-installation on a SSD that caused the issue. In short, F9 at boot still doesn't work, neither the system reset or refresh in Windows.

Besied, I later realized that WinPE 5.1 is the latest version for Win 8.1, while I used Win 5.0 because the Macrium Reflect disk creator only has a choice among PE 3, 4 and 5.0.

I would be thankful for any advice from expert users!

My laptop is fairly new (got it in May) and it came preloaded with Vista Home. Last night, I was on the computer when it froze up. The ONLY thing I did the moment before the blue screen of death appeared was I had got an Apple software update thing and I declined to install it at that moment. (nothing out of the norm) I don't know if it has anything to do with my problem but other than that, I wasn't doing anything out of the norm.. I hadn't even gone to a strange website.

Now, when I turn the computer on, I get this:


Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your windows installation disc and restart your computer. (Which I don't have because it was pre loaded)
2. Choose language settings, the click "next".
3. Click "repair your computer."

If you do not have this disc, contact your system admin or computer manufacturer for assistance.

Opps, there is no Disk Mgmnt screen shot attached and .. the screen shot you did attach does not show an error, only the install percent complete. These things happen.

Since you're just beginning, it might be more expedient to start over.
See: Windows 10 - Dual Boot with Windows 7 or Windows 8 - Windows 10 Forums

I would delete the D: partition, leaving it raw/unallocated, and let Windows manage it during the install.
Be careful - only the D partition.

The tutorial should guide you all the way through. Read it and ask questions before you begin - it's easier to answer a question than to fix something or start over

i have done alot of reading about this but nothing can help because it all requires you to be able to log into windows or safemode first. i have tried 2 seperate windows 7 discs that are proven to be good and an ubuntu disc and an xp and a repair disk.
the windows 7 discs go to the "windows is loading files" and then to that error done it around 30 times. the xp and repair discs just stay on the blank screen with a flashing underscore and nothing will happen. the ubuntu disc can start up in a live session but when you try and install it it freezes at 5% and will never get passed it.

i put the hdd into another pc and done the command prompt partitioning and clearing as well as using gparted and went through all the discs again and all happened the same so i just went out and bought another hdd thinking that will fix it.
