windows 10 error: 'inaccessible boot device'

Q: windows 10 error: 'inaccessible boot device'

Can't access pc after changing to windows 10. Can't get anything except a blue screen and constantly recycling 'inaccessible boot device' and we'll restart for you. Took several hours downloading osl (or whatever) on my laptop and; put it on usb and tried that in my desktop but that was no good either. Also tried original windows 7 disc and a boot disc that I bought and also the backup discs none of which have any affect. I can't afford a new pc on my pension and I can't afford to take it to a mechanic. Any clues anybody?

Preferred Solution: windows 10 error: 'inaccessible boot device'

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hi all

Hope someone can help me

My windows 7 hdd will not boot up. I get an error message saying:

The boot selection failed because a required device is inaccessible

Now I have tried startup recovery several times with no luck.

I have tried bootrec.exe and tried to rebuild it but no luck

I have tried to use the recovery disks I made when I first bought the laptop but it doesnt allow me to select the repair windows files and preserve files options. It allows me to select the fresh windows install option however when I do it it always fails and says a path cannot be found.

I have tried the chkdsk/r in command prompt to fix any problems and that was successful but still no luck.

here is a screen shot of my disk management, it is disk 1

I just need access to my files on there. I have tried to mount it via acronis so it works as an ordinary disk but it doesnt pick it up

Please could someone help

For days one of our computers here at work has been acting strange....booting to windows, then rebooting. I booted to safe mode, then restarted to normal mode it seemed fine...then one day...blue screen! The error "inaccessible boot device error" comes up when windows trys to load. I can F8 to pick safe mode, but it returns to the blue screen.
Any thoughts on how I can fix this problem? I have searched for answeres but there is nothing to really grab hold of and work through.

On another note, while this first computer was out of commision I moved one of our other computers over to that workstation..and two days later it started acting funny too. No blue screen yet but did the restarting thing today and also went to a black screen with one line saying HD error. What gives?? As a side note, both computers had a automatic windows update happen recently. Also, I was wondering, could a faulty battery backup device be the cause of this? A virus?

Thanks so much for any help at all.

This may seem stupid, but I have an old HP t5500 Thin-Client which I have altered and hooked up an IDE hard drive to. The BIOS detects the HD just fine, and I can install any version of linux without fail from the external cd drive. The challenge for me is to install Windows 2000/XP. Every time I try to boot from the windows disk, it loads the drivers, then before it loads the partition screen, it BSODs on me and gives an INACCESSIBLE_BOOT_DEVICE error. From what I've read, I traced it to the USB drivers loading too late in the setup process for it to continue loading from the USB CD drive.

I've even tried hooking an IDE cd drive directly to the motherboard but it refuses to boot from it, and there's no way to manually select the boot device by pressing any F(1-12) key.

Settings are configured correctly in the BIOS to boot from the Flash RAM (or in this case, any IDE drive), and I do have USB booting capability.

What I want is to install from my USB CD drive.

Any ideas?

I'm running Windows 10 64 bit without any problem. Dual core cpu 3 gb ram gigabyte motherboard. 320 gb sata hdd. Everything's okay until i connect an additional 160 gb sata hdd from another computer.

What happened:
1. When i connected 160 gb sata hdd, it booted XP os. I know that bios recognized it as the first boot device.
2. I changed the boot order where my windows 10 installation is present.
3. BSOD with a message inaccessible boot device.
4. When i remove that 160 gb hdd, windows 10 boots like nothing has happened before.

What i did:
1. Booted live ubuntu and deleted partitions on 160 gb hdd from disk utility menu. It has some extended partitions which I'm going to delete as my pwfree_64.iso gets in my bootable usb flash drive.

What i want:
I want that 160 gb hdd fully formatted connected to my computer without any boot errors.

Please help me. I've encountered this issue for the first time in my life.

A:Inaccessible boot device error

Still seems like bios is the problem. Do you have a BIOS that supports both Legacy and UEFI booting? You might have changed the boot priority for Legacy but not for UEFI. Is there an option to enter the manual boot menu screen? On my laptop it is F9, on my desktop it is F11. Try entering the manual boot menu and see what the options are for booting, that will help tell you what to set as the priority device. Also, make sure the SSD is connected to the first SATA port on the motherboard, then I like to do CD/DVD drives next, then storage hard drives.

Also, post a complete disk management screenshot and that will help us:

Hi, I started having the Inaccessible Boot Device error after I installed a new memory RAM on my laptop ASUS x501A running Windows 10. After installation, I got a BSOD but windows was able to boot after restart. Everything worked fine. I installed new software after that (Spybot and another one that disable bad startup registry-can't recall the name of that one). Everything worked fine until the PC froze. I left it for 5 minutes, but it was still frozen. I had to turn it off (pushing the power button) then on. Here is where I got the inaccessible boot device screen and tried everything suggested on the web with no luck. Reinstalled my old RAM, running automatic repair, modifying BIOS, Chkdsk, SFC, downloaded windows 10 installation on a USB flash drive, and many more.
1. I can't boot into safe mode (I get the same BSOD after selecting safe mode option#4)
2. I can access CMD. From CMD I ran notepad and then tried to open a new file (to check if the HHD is readable); I was able to see all my files and the windows files, and I am able to create/copy/paste files through notepad's [open-file] window. However I am getting really frustrated with this issue. I have a lot of programs installed and don't want to try a clean install.
Any help would be appreciated...
Thank you in advance.

I'm getting a stop error 0x0000007B Inaccessible boot device error when starting win2k.
This started when I removed a hdd with win2k on it from an old pc and put it into a new pc running winxp in order to transfer important files to the new pc.
When the new pc was started up the win2k disk could not be accessed. I received a message saying that the disk was not formated.
When I put the win2k hdd into the original pc I received that stop error. I could not get win2k to boot in regular, safe mode, last known good config. or via the recovery counsel using the automat option (I dont have recovery disks).
The original files appear to still be intact but the only way I could view them was by using a ntfs partition tool.

I would really like to be able to copy thoes files off the win2k hdd and if possible get the original win2k pc restored with all the files intact. I've already tried using the help from microsofts web site and couldnt solve anything. Any help would be greatly appreciated

--note-- On the microsoft website they had several fixes using the regedit but thoes didnt work because winxp couldnt see anything on the win2k disk.

-edit: both hdd's are ntfs format

Hi there
EVERY TIME I boot my system I get an bluescreen error message saying operating system couldn't be load because a required file is missing or contains errors. Error code was 0x000000e and File: \Windows\system32\winload.exe.

I am caching the system with intel rapid storage tech with a OCZ agility 3 64GB ssd and a WD Black 2TB hdd. My mobo is a asus sabertooth z77. Windows 8 x64 Enterprise

My work around that i have found that works every time is to hit delete and go into bios, then as soon as im in bios choose to discard changes and restart.

As soon as I have done that windows starts instantly

Any ideas?? Having to do my workaround annoys me, I would much rather fix.

I have a Lenovo G510 laptop which I got as a birthday present last September. It was preloaded with Windows 8.1.

In February, I started having problems. I had a BSOD crash, "IRQL Not Less Or Equal", I think. Knowing very little about computers, I blundered my way back to a functional computer. Every few months since then, I've gotten an Inaccessible Boot Device error.

Now, usually this was fixed after a few rounds of startup repair and restarts. Now, the problem won't stop. For several days, I've been restarting, shutting down and turning on, or even pulling the battery out, but the problem isn't getting resolved like it used to. My laptop is inoperable, I'm posting this from my friend's.

Worst of all, after trying to boot, then giving me the error message, the system shows the loading screen again, then goes to the "Please Select Language" initial setup page. From there, when I input US English, it just falls back into the loop. Can someone tell me what the heck is going on here?

I have a problem, I replaced my motherboard after it died and now during startup I am getting the STOP ERROR inaccessible_boot _device. I am running Windows 2000 Server and would rather be using XP. The STOP ERROR hits while trying to load windows. It is recognizing all of my memory and hardware on the startup but crashes right after the windows screen pops up. I would love to format the c drive and start over but when I boot from a startup disk it tells me that the C drive isn't there ("invalid drive specification.") I am fairly new to the tech world and would like to fix this myself. THANKS for any help

A:inaccessible boot device error after motherbord failure and replacement

The reason your new mb will not boot up with the old hd is that you probably installed proprietary drivers for your chipset. Since the old mb died I do not know of any way to remove the drivers. I am not sure if you can boot in safe mode and remove them that way.
When you use the boot disk, are you using fdisk to remove any non dos partitions? I would think you have ntfs that is why your dos boot disk will not see the drive. If you need instructions on running fdisk, post back and someone will help you.

T-540p - Windows 10 Pro x64 (upgraded from Win 7 Pro) I'm having the Inaccessible Boot Device problem discussed elsewhere here, and I need is to have a working bootable DVD or flash drive. Couple of questions. I created a system repair disk on my hub's T-530, but mine wouldn't boot to it (non-system drive error) when I changed the boot order to boot to it. Is it still possible to create a disk or flash drive to actually boot to Windows vs simply allow it to be reinstalled? I have a fully functioning command prompt, but sfc does turn up some anomolies, and I assume I need to be booted elsewhere to fix them? I see all my files on C and a backup drive just fine at the cmd prompt, and was able to get all  my files to the backup drive OK using xcopy (restoring system without losing files option does not work).  Chkdsk showed a few bad sectors, plus the "MFT Bitmap attribute is incorrect"--is that indicative of an impending disk fail? Given safe mode is not even showing as an option, I'm guessing the boot manager etc has been fubar'd. Is there any way to repair this? Will reinstalling Windows 10 even affect that? If the HD is fubar'd I'm guessing not. I'm assuming I'll need to work with Lenovo on this as it's still under warranty, but hoping there's an easier way. TIAelaine

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, but it hadn't been booted for over a week before the event. Any suggestions?

I have a question about Windows cloning on the Y470. I tried to clone my system to an SSD using the Windows 7 backup/restore feature, but I'm getting an error that says "The boot selection failed because a required device is inaccessible". The error suggests using the Windows install disc to fix the problem. Does Lenovo provide a physical disc or ISO for Windows? I tried downloading the ISO directly from Windows using my serial number, but I got an error telling me to contact the computer manufacturer instead. Alternatively, if they can't provide a Win7 install disc, do you know if the computer's built-in Lenovo OneKey backup tool will work? It takes several hours to create and then restore a full system image, so I don't want to repeat the process without confirming that this is the proper solution.

Last night i was trying to update my AMD SATA AHCI Controller driver, but i shouldn't do while being sleepy....

My hand moved before my brain realised...I uninstalled the device BUT i also checked the option for deleting the drivers.

Now, i get the error while booting :


The boot selection failed because a required device is inaccessible

What i realise is that windows are trying to find the device needed to boot ( stored on boot info) , but device is not there.

Ι already searched the forum for similar problems and already tried to do a Startup Repair from Windows Installation Disc repair menu (3 consequent times as written), with no result.

No restore points either.

Is there any way to manually fix this or my only path is a repair install ? All my data are safely backed-up.

Thank you in advance for your help.
ΕDIT : I don't know if this is the proper subforum for the above problem, i posted here because it was caused by a driver uninstall. If mods/admins think it does not fit in this subforum please tell me.

A:Error 0xc000000e "Boot Selection failed- Required device Inaccessible"

Well, i found the solution after some 50-60 Google results reading...

Solution was found in this page.

Analytically :

I loaded Recovery Console from my Windows 7 Installation Disk.

Had the AMD SATA Driver folder copied to a cd from my second pc. Driver directory was "W764A"

Ran diskpart and list volume to check the cd's volume letter

Ran the following command ( D: is CD ROM, D:\W764A is Driver Directory, C: is Windows Installation ) :

D:\dism /Image:C:\ /Add-Driver /Driver:D:\W764A\ /Recurse
I typed exit to exit Recovery Console, rebooted and voila....Windows Started normally...

Glad it was solved....

Recently my PC stopped responding, so i waited (an hour), and my PC still didn't respond(no Ctrl ALT Del, no Ctrl Shift Esc) so I cut the power supply(probably not the best thing to do) and restarted. After starting up the login screen didn't appear, instead i got a black screen(PC still running), so I cut the power supply(again probably not the best thing to do) and restarted. Like I expected I got a BIOS error screen telling me there went something wrong and asking to start normally or to start startup repair. No matter what i chose, I always got the following error:

Signed up for DSL. Got the modem and the installation disk. Started through the process. Stopped me and said I didn't have an ethernet card, which I do, but had previous problems so maybe it was uninstalled.

Went out and bought a new ethernet card. Installed in an open PCI slot. Tried to install the drivers off the floppy provided. Got error message that inf file did not match the one specified. Took the card out; took out the old ethernet card; put the new one in that slot; tried again. Same error message.

In the meantime, my 5-year-old turned off the power source while the computer was on. When I tried to power up again, I got the following error message: ***STOP: 0x0000007B (0xF081B84C, 0xC0000034, 0x00000000, 0x00000000) INACCESSIBLE_BOOT_DEVICE.

I am using Windows 2000 Professional, installed on my home computer by the IT guy at work, who now does not have time to try to fix it.

I am looking to fix this error but have no real idea what the problem with it is. I am a reasonably good novice with pc's and have tried running both 'chkdsk' and 'fixboot' with the Windows recovery centre, both to no avail.

Welcome to the forums

one option since this a dell is to call tech support and get their help. it is a dell and everyone raves about dells tech support - so make sure to let us know how good they are. Dell also has a great feature in that you can restore it to its bought condition. Again, you have to get dell support to do this. if you have data you want to save, you lose that however. dell should be able to help you access your bios and make sure the boot device is turned on...doc

hi I have been trying to install XP 64 bit on a partition on my laptop and half way through i get a blue screen: 0x0000007B inaccessible boot device and this is quite frustrating because i can install XP 32 bit successfully but not 64bit.

When you power on your computer, look for a message telling you which key to press to enter your BIOS Setup - usually Delete or F2. Go into setup and change the hard drive setup from SATA to something like Compatible Mode or IDE Mode. The description varies. After you get Windows installed you'll have to update all your chipset drivers then change the hard drive access mode back to SATA.

I am running 2000 pro and every time I try to put sp1 or sp2 on the computer it comes up with an inaccessible boot device message. I tried the recovery disk, console but everytime I end up haveing to reload windows on my system. The whole 30 gig drive is formatted as ntfs and split into two partitions. Windows 2000 pro is loaded into the first partition.

I have tried everything I could think of so any suggestions would be appreciated.

I installed the board and hooked up all the drives, hoping that it will start right up. Bad news. Blue screen. Inaccessible boot device.

Last night when l was running out of my office l was in a real hurry to catch a train and when l tried to shut dowm my IBM Thinkpad 650x it froze so l manually shut it down but when l tried to start it up again this morning l saw the following;

*** STOP: 0x0000007B (ox81423030, )xc0000032, oxc000032, ox0000000, 0x0000000)
Inaccessible boot device.

If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated, run CHKDSK/F to check for hard drive corruption, and then restart your computer.
How can l check my computer for a viruse if l can't get into it??

What did l do this time and how can l fix it?



A:inaccessible boot device screen???

More than likely it's not a virus. Most often than not, this is caused by a bad hard drive. I would replace the drive.

Been working on this for weeks to no avail. I have Win 7 on on ssd and Win 10 on another ssd. I am not dual booting but switch to the drive I need in the bios. Using Casper 8.0, I clone the Win 7 and Win 10 to backup internal ssds. These internal backup drives have no issues booting. I also clone the Win 7 and Win 10 to LaCie usb3 thunderbolt ssd drives. This is where the problem starts
The Win7 has no issues creating a bootable usb3 backup.
The Win10 will not create a bootable usb3 backup.
When trying to boot to the Win10 usb3 drive, I get the "inaccessible boot device" error then a restart.
I have tried just about everything I can find but nothing fixes the issue.
Any suggestions?

I just replaced my P11 450 with a gigabyte mb and a P4 1.8. While initially all looked well, during the boot into Windows 2000 that wonderful blue screen with tons of words, among them, inaccessible boot device.....check your hard drive...blah, blah, blah came up. The only difference between the new configuration and the old is the MB and processor. What stupid thing did I miss? I'm guessing that there may be something in the BIOS that I've misset. Help!!


A:[Solved] Inaccessible boot device

You will have to reinstall Windows. It does not like you changing the hardware, which includes BIOS and CPU. The reason is Windows create a Hardware Application Layer (HAL) to separate the OS from the hardware when installed.

I'm in a quandry here and can't figure out how to get out. I was reinstalling my HP scanner software when a stop error screen came up during reboot. I tried restarting and I keep coming back to the same screen. I tried booting from my Norton Antivirus Emergency Boot Disk and keep getting stuck at the same screen. I tried going into safe mode with command prompt and still come to the same screen. I checked the connections on the back of the computer and have unplugged the scanner. Still no luck.

Here's what the screen says:

***STOP: 0x0000007b (0xEB81B84C, 0xCOOOOOOE, 0x00000000, 0x00000000)

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Refer to your Getting Started manual for more information on troubleshooting errors.

Where do I go from here?

I had a problem where my XPS 8900 would not power on. I sent it back to Dell for repair. To protect my private data, I removed the hard drive before sending it back. Dell replaced the processor and shipped it back to me. I put the hard drive back and powered the PC on. Now I get the Inaccessible_Boot_Device error.
I tried the following:
1. Swapped in a different SATA cable.
2. Plugged the SATA cable into a different port in the motherboard.
3. Checked the drive for errors and didn't find any.
4. Restored a system image to the drive.
I have another hard drive sitting around and my next step is to install Windows 10 on it to see if it will boot.
Is it possible that the Dell tech changed some BIOS boot settings and I just need to set them back? What settings should I check?

A:XPS 8900 - Inaccessible Boot Device

However it could also be physically damaged.
