Windows 7 Won't Start - Boot Selection Failed / Required Device Inaccessible
Apr 5, 2012
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
status: 0xc000000e
info: the boot selection failed because a required device is inaccessible."
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 went into bios and changed the boot sequence to boot from CD. The keyboard works fine when in bios but when it says press any key to boot from CD the keyboard doesn't seem to function. After that it takes me to this message.

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.

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

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.

My PC had a single hard drive with 300Gig. (I will refer to it as original HD64) Windows 7 Ultimate 64 bit installed. Worked fine for a year or two. Eventually started crashing randomly, attempted lots of fixes but was reliably informed that it could be my hard drive. I decided I would be best with a new HDD and a fresh install. Bought a new hard drive. 250Gig (Will refer to it as new HD32). Unplugged originalHD64 from sata cable and power. Plugged in newHD32 into sata cable.
Inserted bootable USB flash drive with windows 7 Ultimate 32 bit on it. Went through full install including partition creation etc. Install crashed part way through but I think the dog knocked the power lead. Restarted install. Everything seemed to install fine. Plugged in original HD64 into second sata slot. Changed boot priority to New HD32. Booted fine.
Clicked on >Computer and found new HD32 as C: drive and Old HD64 as D: as I wanted it to be.
So far so good. But on next boot the CHKDSK thing ran. Then it booted ok. CHKDSK ran on next boot also. Then I managed too boot normally but realised there were a couple of things not working properly in the fresh install. Things like Windows Picture viewer would not open anything at all and a couple of other issues. And it was especially annoying that CHKDSK kept running. I asked for advice and was told that I should probably just format the new HD32 and resintall from fresh incase the install had somehow gone wrong.
So, I changed the boot order to Old HD64 and logged into my old windows OS which I had left installed in case anything went wrong. From there I navigated to disk management and formatted and repartitioned the NEW HD32 disk. Now I unplugged Old HD64. Plugged in bootable USB flash drive and tried to follow the exact same steps as I followed last time. But instead of going through the windows install I just get ... "The boot selection failed because a required device is inaccessible" (and some other text viewable in the following link).
Here is an example image of the screen I get... The boot selection failed because a required device is inaccessible error 0xc000000f on HP Notebooks - Tricks Guide
So I reboot.
Press F8 to select boot device.
Choose USB flash drive.
I have unplugged the New HD32 and plugged in the old HD64 and done the same thing just to test if its a HD issue but I get the same problem.

I'm not sure where to even begin to fix these problems. Some online searches suggested doing a system repair but I want to get some more feedback here before proceeding.Here is the message from the event log:The following boot-start or system-start driver(s) failed to load:
AFD
cmdGuard
cmdHlp
CSC
DfsC
discache
ElbyCDIO
[code]...
I realized some of these are not Windows 7 related but most are. While the computer "works", I do experience frequent reboots and freezes. Perhaps some of these driver loading failures are part of the cause of my issues.

I have a computer I am trying to refurbish. The old hard drive failed. I purchased a new hard drive. The CD/DVD player on the computer does not work, but I am able to boot from a USB. I was able to install Ubuntu from USB with no problems and now have a new copy of windows 7, 32 bit (computer is also 32 bit). I have tried to boot from the windows copy on the USB drive using many different tutorials as well as using the windows USB/DVD download tool. Each time I boot from the usb stick, a screen comes up that says windows failed to start. It says it may be due to a hardware problem. All other solutions to this involve using the recovery CDs or partition which I am not able to because the CD/DVD drive is broken, and I would like to not have to buy another one.

Yesterday I have installed Mirrors edge to my laptop Asus k50ab, I have windows 7 64 bit, after playing the game, I restarted pc, and then it just failed to start and pc restarted, same thing in all safe modes. I think its problem with graphic card update, i have ATI , and probably installed Nvidia update...
Always writes this error: "A problem has been detected and windows has been shut down to prevent damage to your computer."
Technical information:
*** STOP: 0x0000007B (0xFFFFF88009A9928, 0xFFFFFFFFC0000034, 0x0000000000000000, 0x0000000000000000)"
I tried almost everything, but i think if i will delete that update or something , it will run..

Windows Boot Manager 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, contact your system administrator or computer manufacturer for assisstance. Status: 0xc0000034 Info: An unexpected error occured.This computer didnt come with any recovery disc, only some disc that says power2go 6.0. I tryed my brothers recovery disc's, but he has an HP. so i inserted the disc, and it says windows is loading files with a bar going across filling up twice. When it finishes, a blue background design pops up and looks like sunlight is shining down from the top of the screen and the mouse goes to a blue circle rotating clockwise like its loading something, then the computer shuts back down, and reloads the whole proccess again.
it does this several times then finally displays a message that says:Windows Boot Manager Windows has encountered a problem communicating with a device connected to your computer.This error can be caused by unplugging a removable storage device such as an external USB drive while the device iss till in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing.

When I hit F12, then I get the error:Media test failure, check cableExiting ---Im pretty darn sure its a hard drive problem (Despite the hard drive still being recognized in my BIOS)

I have a strange issue haunting me. On a dual boot PC (Windows 7 x86 and x64 the OS selection (Windows Boot Manager) will not allow me to select with the arrow keys. Also the enter key will not allow bypassing the timer. I recently reinstalled both OS but it never worked previously when I had Windows 7 x86 and XP x64 on a dual boot.
During the install, during the several restarts that occur when you are doing an install it will work and I could select but now I cant. The keyboard is a USB keyboard with wireless mouse.
Any ideas?

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.

Last night I was on my computer and then I shut it down. Today when I came home from work it keeps saying windows failed to start. I tried hitting f8 and loading to the last good configuration doesn't work, safe mode same thing, repairing nothing, so my last resort was my windows 7 cd. So I went into bios and made my configuration boot from cd/dvd popped it in and restarted, a black screen came up saying windows is loading files, then the windows 7 menu came up, picked my language, next, and first I tried repair my computer, I get the little circle meaning its loading for like 5 seconds them it does nothing, rebooted again but this time I chose, install and I've been on the setup is starting for like 20 min. And forgot to mention, when it boots seem like it does good then comes to the screen where it says windows failed and gives me two options repair our start normal, if I pick repair it just reboots and start normal takes me to like the pick your user screen but its just blank no users, so I can't even restore our access the computer.
