Windows 7 Recovery - Boot Selection Failed Because Required Device Inaccessible
Jan 8, 2011
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 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 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 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.

So it all started last night. My computer was unresponsive, and after clicking "shut down" a few times to no avail, I decided to do a hard reset. I didn't think anything would happen, but afterwards it just wouldn't boot back up. It goes to the windows logo and stays there. I don't get any errors, it just hangs there. I have tried many things, so far nothing has worked.
I have tried booting into safe mode. This does not work, it gets stuck at classpnp.sys and stays there. I have tried booting from the windows 7 disc. This does not work, after it loads the disc it will hang at a black screen. I have tried switching from IDE to AHCI. This has worked, but not fixed the problem. When booting into safe mode it will crash instead of hanging.
When booting from the windows 7 disc I can almost reinstall windows, however I get the error "Windows could not format a partition on disk 1. The error occurred while preparing the partition selected for installation. Error code 0x80070057." When attempting to restore windows to a restore point I get the error "The system image restore failed. Error details: Windows backup failed to read from the recovery volume. (0x8078002F)"
I have tried connecting the SSD to a different windows 7 computer in a attempt to reformat it, however just plugging it in would give the same problem to that computer. So, is my SSD toast? Did I mess it up beyond repair? Now system repair will not hang on IDE, but still gives me the same errors. Also, now it says missing operating system. Not sure how that happened.

I have a Toshiba Satellite A505-S69803; serial number Y9340538Q, with Windows 7, 500Gb HDD at 5400rpm and 4Gb RAM... I think that's all correct.Anyway, long story short, I got a b!tch of a virus, which apparantly was doing all sorts of nasty things to the explorer.exe file in particular. So I backed up all my important stuff: files, Uni work, writings, music and photos etc onto an external hard-drive and went about restoring the laptop to out-of-box factory settings by making the Windows 7 Recovery Media Discs. But when I try to use the discs I get told after about 30 minutes The Toshiba Recovery Wizard "Can't read from the source file or disk: PREINST5.SW5" with options to: Try Again (The same thing happens), or Skip (Same message again), or Cancel (in which case I'm back where I started).After the Recovery Wizard failed I chose the option to erase the hard-drive; it then appeared that when I turn on the laptop as normal I was told <Error>: F3-F200-0002 and the Recovery Media Disks still refuse to work.Now, if I turn on the laptop as normal a message telling me to insert the installation disc, choose language and click "repair your computer". So I put in the recovery disc and get the same message.
Toshiba can't help as my A505 is an American model in Britain and out of warranty anyway. Europe Toshiba HQ don't supply the recovery media for the A505 and the American based Toshiba aren't allowed to send the Recovery Media to Europe; so apparantly I get no help from them. And Microsoft can't help me because my laptop was purchased with everything pre-installed so the codes associated with my Windows and Office are comletely irrelevent.I have been told that I need to purchase a compeltely new hard-drive and purchase Windows 7 brand new to get my laptop back up and running. Purchasing a new OS isn't too much of an issue because I can just get XP for a tenner, validate it with Microsoft and then get a student upgrade onto W7-Ult for �60. So �70 in total, I'm fine with that. But do I need a new hard-drive too? Or can I rescue everything I already had?

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?

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.

I am trying to install Win 7 Home Premium on a different HD, I have the original install disks, I boot from the DVD drive and the files load as usual but after selecting language I get the message: A required CD/DVD drive device driver is missing. How do I resolve this? And also is there any advantage to installing 64 bit, my processor does support it.

I have just finished building a new desktop, here is the config:

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.
