Inaccessible boot device

Q: Inaccessible boot device

I am working on getting our Windows 8 image working for an upcoming deployment. I am running into an issue when deploying to the Dell Optiplex 745. I am deploying via PXE and MDT/WDS. This method deploys fine to our DakTech models and even our Lenovo T60 laptops. I can install from the DVD just fine on the machine. I have extracted the drivers from the ?reference machine? and added them to my deployment share. I have still receiving the ?error inaccessible boot device.? This image is from the DVD not a custom image, but I have tried a custom image from my reference machine with no luck. I have also tried both the normal and the legacy settings for SATA operation in the BIOS. I have since run across this issue with a Lenovo desktop as well.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

I'm trying to install windows 2k on this pc and it's giving an inaccessible boot device error(code 0x0000007B)

the real problem is that there shouldn't be a problem.
I resized my main partition to make 2gb of unallocated space.
I partitioned and formatted the space as NTFS
I can access it from vista and move files freely into and out of it,
but when I try to install win 2k it gives a bluescreen error after loading its components.

I'm trying to put 2k on so I can play metal fatigue, system shock, and other old games.

I'm confused as to how there is any error at all.

After researching and tinkering, i have found out that i need to get the SATA controller drivers for my motherboard. I have a Dell XPS 410 but i can't manage to find anything useful on the dell site, I need to know where I can find a SATA controller driver. HDD is a WDC WD5000AAKS in case you need to know.

I don't have a motherboard disk and I don't have the Dell drivers and utilities disk, which probably wouldn't have it anyway.

Ive had a blue screen appear when i try to start-up windows XP. It says that there has been an error and that windows has shut down to prevent problems.
It didnt disappear so i was forced to reboot windows, that is now in a new partition with little space, the old drive is still there, but still shows the blue screen when i try to start it up.
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.

Any help on this matter would be nice, and anyone who knows how to fix it would be greatly received.

The full Technical Information on the message reads:
*** STOP: 0x0000007B (0xFA2C7640, 0xC0000034, 0x00000000, 0x00000000)

I am running a computer with: AMD Athlon XP 2400+ 2ghz, 224mb RAM.

Please ask for anything else you may need to know, but as i say i am quite a novice. Please help.

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 unplugged the hard drive, took out the new ethernet card, turned on the computer again, but I keep getting the same message.

Keeping in mind that I'm not very computer literate, can someone walk me through the steps I need to do to get the darn thing to work again?????

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

Hello! After yesterday (05.09.17) system update which was the only option to shut down my PC, I cannot start it. The automatic fix program said it was the error designated as Inaccessible Boot Device. I tried the system restore from two recent restore points offered by my PC. Didn't help. I tried startup repair - didn't help. System image recovery didn't work because windows couldn't find a system image on my computer. Not sure if I would like to try to reset my PC since this will bring the state when I got my PC by deleting all the software packages I installed but saving personal files. Is there any option I can fix my desktop without doing reset? Thank you.

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

SATA operation changing from INTEL Rapid Start or AHCI  or ATA.
However it could also be physically damaged.

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?

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!!

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.

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.

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:

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.

It sounds like the BIOS is not directing the boot to the correct disk. I assume that nothing else has changed. Check the disk connection. Try booting with a DOS or win98 disk and run fdisk to see if the drives and partitions are viewable (don't change). If you can see the partitions as they were, you might try exiting first and run "fdisk /mbr" (no quotes) and if that is not the answer, try a repair install of 2k to see if it recognizes a previous install.

I bought a new laptop and in order to move my data to it, I took out the hard drive of my old laptop and hooked it up to a SATA device. After that, I put it back in the old laptop. When I turned it on, it would not boot because of the device (hard drive) being inaccessible with an error code 0xc000000e.

I do not have the Windows installation CD to run the repair, I ran a BIOS diagnostic and it found nothing, the boot order in BIOS is correct. Any further ideas?

What OS is on each machine?

If they're both Win7 64-bit then create a system repair disc on the working machine and boot the other using that disc and select repair from the menu.

If they're different, you could try downloading the ISO here. Be sure to select the correct bitwise ISO (32-bit or 64-bit) and then create a system repair boot disc.

i can boot with a win2k boot cd but i dont know what i can do with it; i can get to the dos prompt but when i do a dir c:, it lists contents of another HD (not the main primary partition); it doesnt see any other partitions from the dos prompt

i have 5 HD on this computer, and am on windows 2000 pro

i dont know what the next step to figure out the problem is.

Thank you very much.

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?

I installed Win 7 on another SSD and it works fine. But my old SSD can't seem to boot win 7.

The SSD is fine, I can see the files. GParted marked the main 'partition' as boot.

The repairing of it says something about missing partitions and trying to fix it. Though that didn't seem to work.

I've also noticed that along with main partition the System Reserved partition decided to show itself, not sure if that's related. Also, in Diskpart, there doesn't seem to be a name assigned to the volume, not sure if that plays a part too.

I need some help fast please. I recently booted up my gaming rig after swapping out a 7970 graphics card and upon system boot up, as the windows 7 logo appeared the system crashes and a BSOD appears for a split millisecond and I'm asked to start up repair windows or start windows normally however when I click start up repair a black error screen appears with the following message and error: The boot selection failed because a device is inaccessible error state and an error code:0xc000000e. Now of fixed this before multiple times except this instance nothing seems to work Ive tried the following:

- check for any unplugged or loose cables
- Re installed my ram
- Booted with on board graphics
- unplugged all usb devices and external devices with the exception of the keyboard and mouse
- Booted with system installation disc and attempted system repair several times only with the same outcome of wanting to restore from a previous system restoration point however it always fails
- changed the boot type to IDE which made the system boot furhter past the logo screen however it still crashes with the same error
- From the system installation disc I ran a chkdsk /f and no corruptions or bad sectors were found

However, I did run from the installation disc a "bcdedit" and my osdevice was unkown and my boot manager and boot loader were set to two different drives on being D: and the other being C:. So I re-linked all three back to the D: drive as the windows... Read more

My desktop computer was struck by lightning last month and every since then, it's been on a blue screen loop whenever I start up the computer. It gives me the Inaccessible Boot Device error. None of the troubleshooting solutions work (system restore, system image recovery, system repair, UEFI firmware settings, go back to the previous version) nothing works. The drive is fried. The drive was even switched from C: to X:

I was told by tech support that it's not damaged severely because it's still able to turn on and boot up. but I would need to reinstall windows completely. They offered to sell me the recovery disk but I am looking for another option.

I have downloaded Windows 10 to my flash drive and tried to boot Windows that way but when I got to the stage "Where do you want to install Windows?". The box is empty and I clicked load driver, the USB drive showed up on the list under Browse but I kept getting an error saying "No signed device drivers were found. Make sure that the installation media contains the correct drivers..." when I clicked USB Drive (C, ESD-USB (D and Boot (X

I went to HP's website to download the storage drivers for my desktop on my flash drive thinking that would do the trick but that did not help.

I have no clue what I'm doing and I'm basically taking bits and pieces of information from the internet to try to come up with a solution but the frustration has set in because I had my computer set up to... Read more

A:Inaccessible Boot Device - Blue Screen

You appear to actually have a HP 251-a123w Desktop PC (N0B07AA).
It was introduced in September 2015 in the U.S.A. and came with Windows 10 Home 64-bit.
What's the exact serial number and product number on yours?

If you go HERE and follow the instructions, you can purchase a USB recovery media kit for it.
Using it will revert that desktop back to its original new condition, along with all the drivers, programs, etc. that came in it.

If you go HERE, you can download the Media Creation Tool, then use it to download Windows 10 Home 64-bit, then create a bootable USB thumb drive or bootable DVD.
Using it will install Windows 10 Home 64-bit, but you then will need to install the needed drivers and programs afterwards.

You admit to not being computer-knowledgeable, so you'll probably need someone who is to help you.

I have a computer I built myself and one day I was running it and chrome seemed to keep inexplicably closing without warning. I decided to restart my computer on when I booted it up it hit the Windows 8 logo on black background with the white circles, waited a little, then went straight to BSOD with the error: INACCESSIBLE_BOOT_DEVICE. I've tried the multiple options in the recovery advanced options, and I made a recovery media from a laptop i have, but when I tried to use it said "The media inserted is not valid". I'm not quite sure what to do. I may open it up to see if there's a loose connection or something. Please help.

A:BSOD on startup. Inaccessible boot device

Definitely check your connections, specially the hard drive SATA data cable.
To be sure, you can swap the HDD data cable with the DVD.

Installed Acronis True Image Home 2011 a couple days ago. I did not setup any items within Acronis yet for backups, etc. After install my system appeared O.K. and have shutdown/restarted several times without issue. Yesterday, the computer shut down inadvertently, then at boot i get this message:

Title Screen: Windows Boot Manager
Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.

Problem? I suspect something with Acronis damaged by Windows 7 boot files.
How to fix????

In reading the various postings on the web (including Windows 7 forum!), it seams that Windows Startup Repair would be the best bet to resolving my issue. I put the DVD in, reboot, I see a scroll bar the bottom and text says "loading files....", then I see the "Starting Windows" splash screen with the Windows 7 logo...and that's it. The system never gets to a point where I can choose my language, select repair options, etc.

So....I read on the forums the Easy BCD would be a good tool to fix my issues. I downloaded it on a separate system and check it out. It looks like a GUI based program, so I'm confused on how to run it on my Windows 7 system that won't boot. Can I make a bootable version of Easy BCD?

Is correcting the BCD my issue? I don't know

I loaded Partition Commander 11 to check things out...I see a "System Reserved" partition which has bootmgr and the BCD files on it, I also see my partition where Windows 7 is ... Read more

A:oxc000000e Boot failed-required device is inaccessible

Please post back a screenshot of your maximized full Disk Management drive map with listings, using Snipping Tool in Start Menu.

Not sure how Win7 booted if you deleted SysReserved partition then only marked Win7 partition Active but didn't run Repair a few times to write the System boot files to 7 partition with only it's HD plugged in.

Possible that Win7 may be booting off the XP partition which is why we need to see the screenshot and know what you want to do.

Hi Guys--first post,any suggestions for my issue please....
I acquired an used desktop hp P6790 running Win 7 Home Premium,64bit. Nosoftware discs.
Worked fine until I tried to install Window updates which resulted in black screen with only the cursor on it.
Tried to reboot in safe mode/safe mode with networking but after a brief scroll of drivers loading it stops at....
                                             'windows\system32\drivers\AVGIDSEH.SYS'           and message 'Please wait.'
After some time it reverts back to the black screen with cursor.
More amateurish tinkling produces...

                                       'Windows failed to start A recent hardware or software change might be the cause'

A:''Boot selection failed because a required device is inaccessible''

Old hard drives are mechanical devices with spinning platters and reciprocating heads. These moving parts cause wear. And, when this wear becomes great enough, it is no longer possible for the heads to zero in on exact locations where data is stored on the hard drive. In other words, it's simply worn out.

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

I work for a company that currently supports over 4000 Windows 2000 proffessional computers in a business network environment. As of late we have been receiving at least 5-10 tickets a day on computers out in the field with a BSOD Inaccessible Boot Device Error. Now if we have the users hit f8 and choose Last Known Good everything seems to go back to normal, but this is only if the users have not tried rebooting a number of times before hand. If they have rebooted over and over again we are able to go out and run the Windows 2000 recovery console from the Win2k Install CD, to quickly repair the error and get windows back up and running.

The only thing that has changed on our network is that we have gone to Microsoft's SuS system to push out OS updates. This happened about two months ago, previous to SuS we were using Patch Manager. We did turn off the Win2K rollup pack that had the known BSOD error, but even still the computers are still coming in as I said 5-10 a day with the Inaccessible Boot Device BSOD Error.

Our computers are all MS Windows 2000 Proffessional, the models are a variation of Dell Optiplex Desktop machines, I have seen the problem on the GX240, GX260, and GX270 model so far. All computers are up to Service Pack 4 and run in a DHCP domain environment. Is anybody else seeing this or have any idea what could be going on here? This is pretty much new to us as up to about 2 months ago we rarely had any of these BSOD errors coming in unless it was Hardwar... Read more
