Windows 7 Boot Error 0xc000000e - Required Device Inaccessible
Dec 9, 2012
This morning when I went to run on my windows 7 32-bit installed PC, I was greeted by an error message saying "The boot selection failed because a required device is inaccessible". This is odd because last night it was working perfectly, with no problems. I've tried several solutions, like using the repair CD 3 times, to no avail, as well as writing a new mbr through Linux, using testdisk. I also know the whole hard disk isn't compromised since my Linux dual boot is still working with no problems from its partition.

Okay, so this just happened out of nowhere. Nothing seems to have led up to this -- the system booted and shut down successfully, and no software updates or installs were done during the period of time it was on when it was last working. I've attempted many things, but none seem to work. /ScanOs reports no OS detected, while startup repair said the OS was booted successfully. bcdedit also shows no directories linked to "unknown". CHKDSK reports no bad sectors, so such can be discarded. This happens every time I attempt to boot to Windows 7 (Home Edition, x64). I have a copy of Fedora 17 set to dualboot with it

I have a pc that has been running windows 7 pro fine for a couple of years. Today it wont boot stopping with the message: "Windows failed to start.A recent hardware or software change might be the cause."
To fix the problem:
1.Insert windows installation disc and restart your computer
2.Choose your language settings and then click "next"
3.Click "repair your computer".
If you do not have this disc contact your system administrator or computer manufacturer for assistance.
Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.
This machine has only one dvd drive and one hdd. I have checked the boot list in the bios settings and the cd drive is first then the hdd second. If I insert the windows 7 cd and press any key to boot from cd when prompted I still end up at the "windows failed to start " screen. At this point I have the option to select "Launch startup repair" or "start windows normally" but I cant select them, the machine just counts down and continues to try to launch startup repair and fails with the 0xc000000e error.

I am not able to run recovery on by laptop. When I try to run recovery from hard drive or even booting system from DVD ROM using recovery discs I get the following error:
Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.
My system is HP pavilion dv6 2150us. My hard drive is dynamic (someone told me that this error is because of dynamic hard drive). Will I have to convert dynamic hard drive to basic to run recovery? Or is there another way around?

I tried to bring my computer out of hibernation and was confronted with: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.
2. Choose your langugae settings, and then click next
3. Click "repair your computer."
Status: 0xc0000000e
Info: The boot selection failed because a required device is inaccessibleRecently I shrank one of the partition on the data drive in order to enlarge the other partition on the data drive. The enlarged data drive contains the folders of some installed games but the system disk is separate and was not altered in this way. I'm pretty sure that I hibernated and recovered from hibernation at least once since that change was made.Could it be that the OCZ drive has developed a fault? Or would it then be unable to even display this message?When I attempt to repair the installation using the Windows 7 disc, the operating system isn't listed. I don't think that there are any drivers for me to load - I think it's supposed to be automatic (the driver must be a part of Windows own included set).

right, i've noticed another thread with the similar problem, here, and apparently it's fixed, but as i'm running my system on a laptop, i'm wondering what i can do to recover my system without any data loss. error message's more or less the same, "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.
2. choose your language settings, and then click next.
3. click repair your computer
if you do not have this disc.........etcetc

i'm running an msi cx420 that's 6 months old, windows 7 32 bit. this problem only surfaced after i defragged my laptop and updated MSE and restarted. to be clear, my laptop isn't of much importance but my data is what i'm worried about. edit: also, i've tried to burn the windows 7 system repair disc on a USB as follows, but with no luck. i'm running windows xp on this computer and if anyone could also help me on this i'd be much obliged.

I have an Intel i5, Windows 7 Ultimate, and an SSD as my main drive and 2 SATA HDDs.One day, I got a BSOD appeared and my PC restarted restarted. After that, the following error appeared: Window failed to start. A recent hardware or software change might be the cause. To fix the problem:
1.Insert ....
2. .... ... status: 0xc000000e info: The boot selection failed because a required device is inaccessible
Also I noticed that BIOS only detected one of HDDs, not SSD neither other HDD.Sometimes, Windows can be started, but it doesn't work very well.When trying to copy data from F: to an external USB, it copies for a short time and then Windows 7 becomes unresponsive. This also happens in safe mode.After several reboots, now Windows will not boot and I get the error "The boot selection failed because a required device is inaccessible." And the BIOS only detects the SSD.
UPDATE: my disks:
HDDs
WDC WD10EARS-22Y5B1
Seagate ST31000528AS
SSD
FM-25S2S-120GBP2 - G.SKILL

I've been getting a BSOD what seemed like once a week for the past 6 months on my laptop, which now won't even boot into windows. The first hdd was the first to go about a year ago as it is rarely even recognized anymore, so I just moved ship to the 2nd hdd which now seems to have followed suit. Before I go out and buy a new HDD a want to confirm that it is indeed the hdd and not memory, or just corrupt drivers or something simple to fix.What's wierd is that when I try to do the recovery disk option or even boot from the original win 7 cd to do a fresh install, I get no where because its so god awful slow now. I literally had to leave it sit to load into the repair disk option menu for a good 3 hours. I can't even start a fresh install of win 7 because of how slow everything is.I also can't press F8 to get into the boot selection menu to select safe mode, or last known good config etc...I updated the bios which made no difference. I opened up the laptop and disconnected and reconnected the one hdd that was easiest to get to(the other is a bitch) and nothing. I also did a scandisk on the only hdd that gets recognized and in the options it said it had a partition size of 0, but had 2 million sectors to scan which it found 0 bad sectors in.Also when it boots up now its not even half as loud as it used to be yet all the fans seem to be spinning.Why would a couple of dead hdds prevent me from booting from a disk or usb to try a fresh install?

Just installed Avira antivirus and rebooted to complete the installation. I am getting the error "Boot selection failed because a required device is inaccessible" whenever I attempt to boot. I have tried using the Windows 7 disc to repair but it does not work as it runs for a few seconds then instructs me to reboot.The hard drive was initially not appearing but luckily I can now access all my files from this OS, however I would really like to gain access to my main OS again. I have also reset the CMOS but it hasn't changed anything.

I Installed Acronis Disk Director Suite 10.1 yesterday on my Windows 7 and got this problem when it boots up I get the option to choose OS. 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.
2. Choose your langugae settings, and then click next
3. Click "repair your computer."
Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.
Then I tried to run the Windows 7 installation disk, I go to the cmd prompt and run the
DISKPART
diskpart
list disk
select Disk X (X=disk where I installed all the OS, should be Disk 0)
list partition
select Partition X (X=partition containing OSX)
Virtual Disk Service error:
The pack is not online
and then i run the Bootrec /ScanOS, it came with 0 identified Windows Installations, this is why I come into the cmd prompt as I could not select the installed OS.
I've tried that from bootable cd to repair the install but the partition of windows7 is not recognized still.

When attempting to install Windows 7 on my computer (it currently has Ubuntu Desktop 12.04 installed, and has no CD/DVD drive), I get the following error; Quote:A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step.I am installing it via a USB stick (copied the install files from my Windows 7 disk, due to the fact there is no CD/DVD drive). I've tried the common Internet solutions such as re-insert the USB stick, and try another USB port, none of the aforesaid have worked.

I'm trying to install Windows 7 64bit. After loading windows 7 setup from my dvd drive I get the error "Required CD/DVD drive device driver is missing." From doing a lot of research, it seems this error has nothing to do with my DVD drive but has to do with the SATA Controller Driver. So I try to load the 64bit drivers for the SATA controller and it finds them okay but when i try to install, it says something like "no new devices found". The SATA Driver(s) are the only it ever finds, except for the time I enabled Raid... Then those drivers showed up as well but with the exact same results.
From another forum I was directed to this microsoft page: [URL] and the resolution says: "To workaround this issue, disable AHCI mode for your disk controller in the system BIOS. Typically the controller has to be changed from AHCI mode to "IDE" or "ATA" mode. "
My motherboard is an Asus P5N-E nForce 650i SLI Chipset LGA775 FSB1333 DDR2 Mainboard. However, I can not find anyway to change the setting from AHCI mode to IDE or ATA. As far as I can tell, nothing in my bios allows me to change that setting... or at best it's unapparent.

I just bought a new Lenovo T430s and a Samsung 840 Pro SSD. Cloned the system by using Norton Ghost (First cloned the hidden disk, then Windows 7 disk) as the manual (Samsung 830 manual) said. Then put the HDD out and put the SSD in. However, the windows failed to bootWindows failed to start. A recent hardware or software change might be the cause. To fix... Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. I checked the internet and just could understand some basic operations. For example, I entered into bios and saw SATA Controller Mode option [AHCI] Did not find any "Storage config" option... in the main menu. Also, I pressed F12 to the boot menu and selected Samsung 840 Pro but still no work.

Recently I came home to find my pc on this black screen with a few things on it such as-"Windows failed to start, this could be due to a recent software or hardware change"-"a required boot device was inaccessible"-"error 0xc000000e"Now my pc consistently crashed after running fine for roughly 30-40mins. I researched this error but most people say they cant boot at all and repairing Windows solved it.Well I can boot, so finding a answer to my problem has been difficult.So far, I've tried repairing Windows and also re-installing Windows, just to make sure it isn't OS or driver related.

I have what appears to be a common problem with Win 7, as I've seen numerous users ask this question here & on other forums, but so far, none of the suggested fixes that I've found have worked for me. I'm trying to install the full retail version of Win 7 Home Premium on a new SATA hard drive in a new 64-bit PC. I'm doing this because the drive that came with the PC had Win 7 Pro on it, but it was a trial version and I don't have a key or disc for it. However, I have a new copy of Win 7 Home Premium, and since I can't downgrade without hacking the registry (which didn't work either, btw), I decided to get a new HD & start over with Win 7 HP.However, when I try to start the installation from the disc, after I click "Install Now", I get the error message "A required CD/DVD drive device driver is missing". I'm stuck there.
The Win 7 disc allows you to remove the installation disc at that point & put whatever CD/DVD you want in the drive to try and find the drivers you need, so I tried the disc that came with the motherboard, which is a FoxComm. I'm able to get into the motherboard's installation disc & select "x64" under "driver" & also under "floppy". When I select those files, I get a quick green moving horizontal band, like it's downloaded the driver. If I select any other folder or drive, I get the error message "No device drivers were found" otherwise, so I believe I'm on the right track.But still I get the same message when I put the Win 7 disc back in --- "A required CD/DVD drive device driver is missing". I also tried installing an ISO image and that didn't work.

I have just finished building a new desktop, here is the config:
Intel Core i5-2500K

Using access to MSDN-AA, I got an ISO and key for Windows 7 Pro x64 (DVD - English). I then burnt the ISO to a DVD using my current computer, a WinXP 6 year old ACER laptop. When trying to do the clean install of Win 7 Pro on the new desktop, the installer starts up fine, but after choosing my language and regional settings, I get the famous "A required CD/DVD device driver is missing" error.
Here are the things I have tried, in vain:
1) Installing the various available SATA drivers from the ASUS motherboard DVD. This doesn't work and gives a "No new devices could be found" error.
2) Reburning the ISO with ImgBurn at 2.4x speed with verify on.
3) Redownloading the ISO from MSDN-AA and reburning the new ISO at 2.4x speed.
Note that I would have tried to make a bootable flashdrive of the ISO (using this guide: Install Windows 7 From USB Drive/Pen Drive ) but since I'm on Win XP on my current computer, DiskPart doesn't work in the same way. I therefore cannot do this, at least not in the manner described in that guide. Talking of DiskPart, I called up the command window in the Win 7 installer, and it shows NO drives at all. In the ASUS EFI BIOS, I have chosen boot priority for the DVD drive, and the two hard drives can be seen from there (although the SSD cannot be chosen as a priority for booting, which is weird, and possibly linked to this problem?).

I am having a problem starting my PC! I have to start it in the boot menu under the RAID option. If I do not do this a message saying "Reboot and select proper boot device or insert boot media in selected boot device and press a key.." comes up, and just keeps popping up regardless of what I press! I would try using my boot disk but for the life of me I can't find it, and as windows 7 was already installed on this computer when we got it 3 year ago, I can't accurately recall if it came with one!I am no expert on BIOS, but I have read other problems similar to this one, and know that if I don't have the boot disk or the OS disk, I will need to know that at least.I am curious if the (Hard drive) is the issue. The BIOS tells me that anything in parentheses is disabled from corresponding type menu.
