Windows 7 won't boot (required device is inaccessible)

I accidentally interrupted a "back-up to a previous date" and now can't get Window 7 64 bit to boot. Tried recovery dvd but no go.
Please help!

Info: The boot selection failed because a required device is inaccessible

A Major problem I've occurred in the past was just getting Windows (XP/ME/98), etc. to go back onto the drive after a former operating system was in place. I've solved the problem in the past by using the manufacturer's diskette or CD (you can download
it from their websites and burn it to a CD/disc/disk/flashdrive). Western Digital (which uses Data Lifeguard Diagnostics in DOWNLOADS/Seagate and others which has diagnostic software free from their site) and has a "bootable" solution
set of files within that when booted to LOW-LEVEL format (that is, buring "0"'s and "1"'s to the drive, hence erasing everything down to the core level, whereas it's destructive to even remove hidden and boot-level info back to the condition when the drive
was first created, pristine state).
After it low-level formats, one can either high-level (format) it, or run Windows on CD, etc. to install Windows back. The premise was that one can place a specific operating system on the former condition drive and by installing a different one (ex.
32bit to 54 bit, or in 98, etc, difference operation layers which tend to cause changes/upgrades going forward to fail.
This has worked for me on numerous occasions and I was able to put any Windows (provided it's supported by the BIOS or operating system met the system requirements (RAM, etc).
Always good to know.

Desktop PC with Windows Vista won't boot up

My Acer Aspire 180 Desktop PC with Windows Vista won't boot up and has a Recovery error message that says it shut down unsuccessfully. Can someone help me with this issue?

If you have Recovery Disk then try to repair install. If you do not have then you have to contact Acer Support for getting them.
Once it is recovered you must update the Graphic Card Driver. Visit the website of the Graphic Card manufacturer to update it.

Creating Recovery Disks when Windows 7 won't Boot

My sister's hard drive is in imminent failure on HP G60-535DX Notebook. Windows 7 won't boot. I need to make recovery disks. I have been able to back up info going into System Recovery Manager, but I don't see an option to create recovery disks to install the system on a replacement hard drive. Is it possible to create the disks or order them?
Thanks,

Windows failed to start. Required device inaccessible.

Windows failed to start. A recent hardware or software change could be the cause. The boot selection failed because a required device is inaccessible . Both hard disk and memory test passed. Please let me know what can be done. I think it's battery issue because it says battery problem but even if I remove the battery it's not going to windows home screen. Also tried I'm safe mode, did not work.

Hi @San16,
Welcome to the HP Forums!
It is a great place to find answers and tips!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I grasp that when you start your notebook you are seeing " The boot selection failed because a required device is inaccessible"
Here is a link to HP Notebook PCs - Resolve Boot Device Not Found Error Message (Windows 8, 7). As you have already tested the hard drive and memory you can omit that step.
If a recovery should be required, you will have an opportunity to backup your personal files to prevent data loss during that process. The link for the recovery process is in the document provided.
Here is a link to HP PCs - Restoring Files that were Backed Up Using HP Recovery Manager (Windows 7) should it be needed.
Best of Luck!

Windows 7 won't boot or run sfc /scannow - says repair in

I upgraded my HP laptop from Vista to Windows 7 and it has been working for a year. This morning the laptop will not boot up and when I run repair it runs it over and over and will not boot up. I run the diagnostics on the hard drive it gets to about 8%
and then stops with #10008 Replace Hard Disk and then SMART Hard Disk Passed. I get into the Windows 7 repair page and run it over and over with no results and it does not list an any operating systems on System Recovery Page. On the System Recovery Options
page it says Operating System unknown. It does not allow System Restore either. I can get the command prompt (X:\windows\system32) but when I try to run sfc /scannow it will not let me because there is a system repairpending that requires a reboot to
coomplete, and so it goes over and over. I tried using my Windows 7 Home Premium upgrade disk but that does not help. I would re-install it but it will not let me do an installation unless I boot the system from the computer and not the DVD. It seems
like I am in a continuous loop to start out 2012 and I do not know how to get out of it. Any help would be great appreciated.

Mark, thanks for your response. I had no success with the others.

I did this and got a different result
Total Identified Windows Installation: 1
[1] C:\ Windows
Add Installations to boot list? Yes (Y), No (N), All (A)=
I tried Yes and it responded This requested system device cannot be found.
I formatted the C: portion of disk and reinstalled Windows 7 Premium Home Edition from scratch and went through setting it all up and over 90 updates, including SP1 and things seem to go fine. System rebooted a number
of times and it was working. Then out of nowhere went restarting on an update it went right back to where I started before. It appears through various operations I loose communications to the Boot file. When I read some of the reports I get the No Bootable
Device available 0x3bc3.
I run the repair disk over and over and then get it to run again.
The difference now is that all the Memory and Hard Drive tests run to completion and say OK. The last time that it happened I got a momentary blue screen that was gone before I knew it and I was back again to where I started. I am
not running chkdisk on C: again and it seems to be doing OK.
Any more ideas for me. I did remove and reseat the hard drive WD3200 just to be sure connections were OK before I formatted and started from scratch. Seems to me that the boot record is out there but I cannot get to it.
Thanks, Dave

Bootcamp Windows Installer won't boot properly on rBMP late 2013

I have been redirected to this community. I will repost the same question I asked in the mackbook pro community. I am new to Apple Support Communities, I hope this is okay for me to ask the question here again.
Here is my post in the other community: https://discussions.apple.com/thread/5922375?tstart=0
I just bought my MBP Retina 13" Late 2013 last week. It came with Mavericks 10.9, and I have since updated it to 10.9.1.
I have installed Windows 7 64bit using Bootcamp, and ran into a situation, which I hope the experts here could give me a hand.
I used the first two options in Boot Camp Assistant (BCA) and sucessfully created a Bootcamp Windows Installer for Windows 7 64bit on a USB Thumb Drive (USB 3.0). Then I launched Boot Camp Assistant again, and selected the last option to install Windows 7 64 bit on the bootcamp partition, the installation went through successfully. Both Windows 7 and the bootcamp drivers are installed, and I am able to dual boot OS X and Windows properly.
However, if I try to launch Bootcamp Windows 7 USB Installer created using BCA as described in the above by holding down <option> key while rebooting, and select the USB device lableled as 'Windows', Windows 7 Installer starts (in BIOS boot mode, I believe) and then it freezes after it gets to the language selection screen, the mackbook no longer responds to either the trackpad or the keyboard.
In other words, this Windows 7 USB Installer boots properly when launched by BCA's third option. However, this USB Installer does not boot properly when launched by selecting 'Windows' after holding down <option> key while rebooting. What am I doing wrong here?
Any help will be greatly appreciated!
Thanks,
Joe

I did create a Recovery Disk from inside Windows 7 this weekend following your suggestion. Unfortunately, this has the same problem as the installer.
However, USB Installer I created for Windows 8.1 could boot properly both in BIOS boot mode or EFI boot mode. This Windows 8.1 USB Installer is created using the standard procedure for the BCA; the only difference from the Windows 7 USB Installer is that I used Windows 8.1 ISO instead of Windows 7 ISO.
With this Windows 8.1 USB Installer, I am able to access the BOOTCAMP partition and perform necessary operations to fix startup issues, and perform backup and restore using the native Windows tools for the BOOTCAMP partition. And no need to spend $30 on WinClone
Thanks for your help!

Windows 7 won't boot with HP c7280 connected

After a new computer build, i installed Windows 7, loaded all drivers and devices with no problems. When the printer is connected via USB the computer hangs on Bios screen. If I unplug the printer then the computer boots right up. Is there a fix for this problem?

I think the solution to both problems is to either disable the option to Boot from a USB device, and turn off an option called USB Emulation, or something named similar to it. The option can be changed in the BIOS of your PC. Please refer to the documentation provided by your PC manufacturer, or call your manufacturer to get this done.

Windows 7 Won't Boot After Nvidia Driver Installed, MSI Gaming N770

Hi I just bought the MSI Gaming N770 2gb and after installing the nvidia drivers, Windows 7 will not boot after my motherboard POSTs.
I bought this to replace an AMD card. I uninstalled all the AMD drivers before putting in the MSI card. I've also run the Display Driver Uninstaller in Safe Mode and everything.
After a few hours of research, I finally came across a thread about flashing a vbios, and something about these cards not working with motherboards with UEFI bios.
I'm using a P8Z77-I Deluxe mini-itx board, with a Rosewill 630W psu.
I have both 6+2 PCI pins plugged into the two 8pin power ports on the GPU.
Is this an issue that can be fixed with turning off secure boot? or by flashing a vbios onto the card? Or is the card a dud? Or do I have to re-install Windows.
If the vbios is required, are there instructions on how to flash it? I have no idea how to flash a BIOS. Thank you!!

Had to update BIOS. All fixed!!!!

Windows XP won't boot, turns off USB keyboard

Hey Macfolks,
I'm running the latest Boot Camp on a 21" iMac (3.06 GHZ) and Snow Leopard. Windows XP (service pack 3) ran great the first time I installed it using Boot Camp assistant, but...
Now when I try to boot to Windows I have two problems:
1. It won't boot up, but freezes on a white screen.
2. It kills the USB keyboard. The keyboard and mouse running through it just stop working.
I can get the keyboard back if I restart, hold OPTION then choose the start up disk -- which I'm shocked works at all because the moment the OSX login screen comes up, the keyboard's frozen again -- then unplug the keyboard, restart again under OSX and plug the keyboard back in to get it working once more.
Honestly, I just want Windows to boot up like it's supposed to. Does anyone have any suggestions?
Many thanks!

I heard a rumor that Windows XP has trouble with iMacs and the new Boot Camp. Can anyone confirm or deny this?
Thanks!

Windows 2000 won't boot after QuickTime 7.03 installation!!!

Thank your VERY much Apple for messing a company computer!
An Interactive Tuturial we bought used QuickTime, and the sound sounded like the instructor was underwater.
I then went to this website and downloaded QuickTime 7.03, the version you PUSH with ITunes as I at first did not see your snugged away link to the stand-alone download.
Anyways after the download, I went through the installation, which at the end prompted me to reboot.
Well thanks Apple, now the Windows 2000 sp4, system won't boot at all!!!
Not even in safe mode!!! Hangs during or after loading fltmgr.sys
Not even after having bootet to the Windows 2000 installation CD-ROM and done an emergency repair!!!
Thank your VERY much!!!
Not only have your installation program caused a working computer to become unoperational for half a day, now it seems we have to reinstall Windows 2000, and ALL programs and their settings which were used on it, causing another half a day or more of loss work!!!
Edited by an Apple Host

Due the this recent catastrophic issue and other, with the official Apple Quicktime player, our company have deciced to uninstall all versions of Quicktime, mostly version 6, on our 158 PC's, and install the QuickTime Alternative instead.

Windows 7 won't boot without optical drive (SSD, Dual HD)

I recently purchased an SSD and an optical drive HD caddy so I could use two HDs on my macbook pro. I installed the SSD in the normal HD slot in order to install Windows via optical drive. When I move my SSD over to the optical drive slot, Windows hangs on a black screen before the Windows logo and never boots. I tried moving the SSD back to the main HD slot but without the optical drive installed, the same symptoms occur - no boot. This leads me to believe that Windows will not boot without the optical drive (which was present during installation).
Perhaps this is a problem with primary/slave drive settings? I learned today that the intel chipsets in macbooks do not have BIOS for Windows and do not allow you to access the EFI. Not sure if that would help anyways.
Has anyone experienced this and/or have a solution?

I am suffering the same issue. Macbook pro 15 inch late 2009 with 8gig ram. I have a 256gb ssd newly installed, a dead superdrive (thanks a bunch for the drop in build quality without the drop in price apple) and an optibay caddy which i intend on having my 500gb 7200rpm previous HDD installed in. I had the normal annoying issues trying to get bootcamp working with an external optical drive. I then had the bright idea of taking my external optical drive case apart and discovered its a sata drive with a sata to usb convertor attached. Got bootcamp/win7 installed fine using the superdrives sata connector with the optical drive (essentially having a temporary internal optical drive again).
OSX and windows function fine as long as the optical drive stays connected. There does not need to be a disc in the drive, i thought windows might be getting boot info from the win disc. Osx boots fine if its just the ssd. Windows hangs with a white screen right at the beginning. Also doesnt boot using boot menu via alt key. Nor using the reEFIt boot menu (installed later now deleted).
Disk utility says it cannot repair the windows partition and says to back up the data and reformat the drive. This also happens if i use a normal sata drive. I am attempting a few more ideas but at this rate i will be virtual machining windows instead. Far from ideal but seeing as my windows pc is now officially no more and there are two pc only programs i need to use for university i dont have much choice i NEED windows. Anyone got a bright idea that may help?

Windows 7 won't boot up

I was having trouble with audio ads. So I deleted the svchost.ext file. but I then suspended the Dcom file associated to it.
Because of all of this, my computer will not boot up into windows. I can get into safe mode but that won't start up into windows either.
Can someone help me.

Windows Vista won't boot in Snow Leopard

Hi everyone
I tried to boot into my Windows Vista Boot Camp partition today and it wouldn't start. After holding down the option key like usual, it just sat there with a white screen. No Apple logo. No partitions to click on like usual. Then my Mac ran incredibly slow and was glitchy. What happened to Windows? Please help.
All responses welcome and appreciated.
Thanks.
macdiscuss

You're very welcome.
I always leave the boot order BIOS setting to boot from the HDD first so as to shave off a few microseconds from the boot time.
When I need to boot from another device such as a DVD in your case, I turn on the PC, at the beginning of the HP welcome screen, I tap the F9 key to get the one-time boot menu.
I select the DVD drive from the list. Then I hit the button on the drive to open the drive, pop the bootable DVD in, close the tray, wait a second or so and then hit the enter key.
After I hit the enter key, watch the sreen for a message that states in substance...attempting to boot from DVD...press any key to boot from DVD...
I press any key and the PC boots from the DVD and off I go...
Looking forward to hearing back from you.
Now remember...making that file is pretty easy, but only if you read both my notes and the guy that wrote the procedure's steps carefully.
There have been a few forum members that I have had to coach during the process, because they were following that guy's every step to the letter, and as I pointed out, there is only one mistake on his first screen shot...but that one mistake is all it takes to stop you cold.
Disregard the part of the text under the first screen shot about "extract the files to the Vista folder."
The files were already extracted to that Vista folder when you ran the X14.exe file by reading the text on top of the first screen shot.
You get past that, and you're home free.
Good luck!

Windows Vista won't boot changing from IDE to AHCI in BIOS

Hi, I've spent a lot of time looking up this problem online. I can find lots of google search results and they seem to say go into the REGEDIT and change the 'msahci' start setting to 0 and even the 'pciide', or 'iaStorV' start settings to 0. But that doesn't work for me. The Windows load screen with the green load bar just keeps going across and Windows never starts up. I have Windows Vista Home Basic.
I saw someone in this forum with a similar problem but they upgraded to Win7 on a fresh install to fix the problem, they were switching from RAID to AHCI. I contacted Intel tech support and they said to try HP or the motherboard manufacturer. I contacted Intel because I installed an Intel 520 series Solid State Drive and wanted to know if they had a driver to get the benefit of AHCI rather than IDE. I know lots of people recommend a fresh install of Windows but I did not get a cd of Windows with this computer
(My computer is a Compaq Presario SR2170NX Desktop
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00835809&tmp_task=prodinfoCategory&cc=us&dlc=en... )
I tried installing this Microsoft fix too. http://support.microsoft.com/kb/922976
I'm wondering if there is an AHCI driver I can install or anything I can do to get AHCI working?
Thanks to anyone who can help!
