How to fix a "stop:0x0000007b inaccessible boot device"

mel_forgotten
i have a dell optiplex GX260 with a windows 2000, Just yesterday i was transfering some data from my pc to a thumb drive when the Pc froze. Pressing the alt+ctrl didnt help so my sis had the pc shut down by holding down the start button for a few mins, i then start it up again but this time windows couldnt complete running, it would only load halfway and the stop:0x0000007b inaccessible bott device came up. i have tried starting in up on safe mode but the same blue screen comes up b4 windows could completely load. i have even tried downloading a boot check disk and booting up from there but it would just say "invaild disk"
i dont know what else to do, pls help.

    First check the Bios see If the boot order is correct, make sure that all your IDE channels are enabled in your CMOS?s ?Chipset Features Setup.?
    Then try to run the Recovery Console . See if this makes any difference.

    Have you tried attempting to start the computer with another HDD in it and the install CD?It's possible that the HDD controller is faulty or the MRR's on your HDD are damaged and preventing it from being mounted and used as a valid Boot Device.
    You could also try the problem HDD in another PC as a slave and see if you can read anything off it.

    Please check the Hard Disk Drive for Bad sectors , as the virus might have caused bad sectors on the hard drive.

    I do have come across similar experience.Try reloading RAM after reinserting Motherboard's buttery. Mutation in RAM Mammary is wiped out and clears way to smooth Booting! On many occasions of HANG UP and then Boot failure this has worked.

    I am having the same issue with a Compaq Deskpro EN machine. At start up there is the inaccessible boot device error message displayed and I do have Win2000 OS installed. If you all have any other suggestions I would appreciate it. I will attempt to remove the hard drive and install it into another machine to read its data.

    Booting from the Win 2000 CD and choosing the first R for Recovery Console. When this opens run Chkdsk /r If it returns with one or more errors recovered, continue to run it until no more errors. Should Chkdsk fail to fix the errors, try MHHD available from their web site or in the UBCD ISO.

    I got the 0000007b error when I put in a new dual-core motherboard in my wife's old HP. It didn't specifically say boot device error, but the solution was the same.
    Look here:
    http://support.microsoft.com/kb/314082/

    Naturally, I had to temporarily connect the old motherboard so I could update the registry. In case MS decides to remove the page, here's the basic info:

    Copy the following information into Notepad, and then save the file on a 3.5-inch disk. Name the file Mergeide.reg, without the .txt file name extension.

    3. In Microsoft Windows Explorer, right-click the Mergeide.reg file in the floppy drive, and then click Merge.

    Windows XP displays the following message:
    Are you sure you want to add the information in A:\Mergeide.reg to the registry?
    Click Yes.

    After the import process is completed, Windows XP displays another message:
    Information from A:\Mergeide.reg was successfully entered into the registry.

    ===========================
    NOTE:

    Being MS, they say to put it on a floppy. You should be able to use a thumbdrive with any fairly recent board. Or, just save it to your My Documents directory!

    Reboot, and it should work.

    But I'll try to parse this.

    Your box has been infected by a virus.
    You get Blue Screen errors, sometimes one starting with 0x0000007b.
    The computer reboots on system failure.
    Safe mode doesn't work.

    "dbm ect so its on total lockdown in my ibm sys config tge"
    ???

    BIOS doesn't mention shadowing or cache settings.
    ------------------------

    How do you know it is a virus?
    Can you boot into Windows at all?
    Do you have an install or recovery disk?
    What version of Windows is this?
    What exact IBM laptop is this?

    Did you try anything listed at the article referenced?

    I also had this problem when installing Windows XP on a Toshiba laptop that previously had Vista on it. The solution was to enter BIOS setup when turning on the computer (usually F2 or DEL button) and set the hard drive mode from 'ACHI' to 'Compatability' mode.
    Windows then installed correctly.

    I owuld start the hunt for all your software (operatining system disc and drives/software)

    next hit up dells website and enter your service tag and see if you can find a replacement HD or give em a call so your sure you get the right one.

    I have an older Dell that just had this problem a few weeks ago.

    The first thing I did was run the dell hard drive diagnostics. If it starts giving you errors, then there is a very good chance that your drive is dead.
    But, you can continue on and try the following:
    Boot to the windows cd, get into recovery console and do a "chkdsk /r"
    This will scan the HDD for bad sectors and mark them.

    running check disk was my saving grace, and luckily I didn't have to replace the hdd. If your machine is still under warranty, then I would have dell replace it, but it doesn't sound like it would be.


    Let us know if this doesn't work, or if you need more help.

    After booting my Dell Optiplex GX620, I got the blue screen of death (BOD) with the 0X7B Stop Error: ???STOP: 0X0000007B (0XF7A71524, 0XC0000034, 0X00000000, 0X00000000)???. It would not boot into a Safe Mode either. In the Safe Mode the first parameter of the error massage would change into 0XF7ABF524 with the rest staying the same.
    I had a slight suspicion that all that was coused by a Trojan virus and not by hard drive failure as many post on the net would advise.
    To solve this type of issues when you can not boot your PC, the bootable CD is absolutely essential item to have. There are several web pages dedicated to bootable CDs. In the past I have used ???Barts PE??? (www.nu2.nu/pebuilder/), this time I tried ???Ultimate Boot CD for Windows??? www.UBCD4WIN.com. If you don???t have bootable CD, try ???List of live CDs??? on Wikipedia or you can just search internet to understand how to make one. It may take some time but, its worth the time as you may need it again in the future. (you may want to remove the firefox or iexplorer from UBCD4WIN to make the ISO file smaller that would fit a regular CD)

    Just to make sure HD was ok, I ran Dell utilities to check my PC components including the HD. It???s a bootable disk and would boot and run some tests. The utility reported some ???bad blocks??? as ???Uncorrectable data error or media write protected???. Since I had more confidence in my hard drive than in Mcaffe virus protection, I downloaded another test utility from my hard drive???s manufacturer???s site (Western Digital) and ran it. WD???s utility fixed the bad blocks but, the BOD STOP Error message was still there.

    After spending almost two days reading tons of posts and trying different things, I was more convinced that I had a Master Boot Sector (MBR) virus on my HD. However, no virus checker on UBCD4WIN CD had detected any virus. I couldn???t run Avira virus check du to license expiration issue. After solving the license issue using this post http://ubcd4win.com/forum/index.php?showtopic=14855 (you can also download the key directly from Avira: http://dlce.antivir.com/down/windows/hbedv.key) , I rebuild the UBCD4WIN and once I ran it ,Avira reported BOO/TDss.A boot sector virus (Kaspersky: Rootkit.Win32.TDSS.mbr, Sophos: Troj/TdlMbr-B, MS: DOS/Alureon.A, DrWeb: BackDoor.Tdss.4005). Avira could not fix it but, at least I knew what and where was causing the 0X7B Stop error.
    HOW to fix it.
    1. Boot the PC from UBCD4WIN and run MBRwizard (Start/Programs/DiskTools/Partition/MBRWizard).
    2. Use option 1 just to look at your MBR info. Next use option 8 and save MBR on your hard drive.
    3. Run Avira against saved MBR file. It should detect virus in the saved mbr file.
    4. Use option 7 to wipe MBR or first 63 sectors. When asked to wipe MBR or first 63 sectors, choose ???2??? for just first 63 sectors.

    Exit and reboot PC into Safe Mode (hopefully it will work this time) and run different virus checks to get rid of some other viruses and trojan you may have.

    NOTE:

    Being MS, they say to put it on a floppy. You should be able to use a thumbdrive with any fairly recent board. Or, just save it to your My Documents directory!

    Reboot, and it should work.

    But I'll try to parse this.

    Your box has been infected by a virus.
    You get Blue Screen errors, sometimes one starting with 0x0000007b.
    The computer reboots on system failure.
    Safe mode doesn't work.

    "dbm ect so its on total lockdown in my ibm sys config tge"
    ???

    BIOS doesn't mention shadowing or cache settings.
    ------------------------

    How do you know it is a virus?
    Can you boot into Windows at all?
    Do you have an install or recovery disk?
    What version of Windows is this?
    What exact IBM laptop is this?

    Did you try anything listed at the article referenced?

    I also had this problem when installing Windows XP on a Toshiba laptop that previously had Vista on it. The solution was to enter BIOS setup when turning on the computer (usually F2 or DEL button) and set the hard drive mode from 'ACHI' to 'Compatability' mode.
    Windows then installed correctly.

    I owuld start the hunt for all your software (operatining system disc and drives/software)

    next hit up dells website and enter your service tag and see if you can find a replacement HD or give em a call so your sure you get the right one.

    I have an older Dell that just had this problem a few weeks ago.

    The first thing I did was run the dell hard drive diagnostics. If it starts giving you errors, then there is a very good chance that your drive is dead.
    But, you can continue on and try the following:
    Boot to the windows cd, get into recovery console and do a "chkdsk /r"
    This will scan the HDD for bad sectors and mark them.

    running check disk was my saving grace, and luckily I didn't have to replace the hdd. If your machine is still under warranty, then I would have dell replace it, but it doesn't sound like it would be.


    Let us know if this doesn't work, or if you need more help.

    After booting my Dell Optiplex GX620, I got the blue screen of death (BOD) with the 0X7B Stop Error: ???STOP: 0X0000007B (0XF7A71524, 0XC0000034, 0X00000000, 0X00000000)???. It would not boot into a Safe Mode either. In the Safe Mode the first parameter of the error massage would change into 0XF7ABF524 with the rest staying the same.
    I had a slight suspicion that all that was coused by a Trojan virus and not by hard drive failure as many post on the net would advise.
    To solve this type of issues when you can not boot your PC, the bootable CD is absolutely essential item to have. There are several web pages dedicated to bootable CDs. In the past I have used ???Barts PE??? (www.nu2.nu/pebuilder/), this time I tried ???Ultimate Boot CD for Windows??? www.UBCD4WIN.com. If you don???t have bootable CD, try ???List of live CDs??? on Wikipedia or you can just search internet to understand how to make one. It may take some time but, its worth the time as you may need it again in the future. (you may want to remove the firefox or iexplorer from UBCD4WIN to make the ISO file smaller that would fit a regular CD)

    Just to make sure HD was ok, I ran Dell utilities to check my PC components including the HD. It???s a bootable disk and would boot and run some tests. The utility reported some ???bad blocks??? as ???Uncorrectable data error or media write protected???. Since I had more confidence in my hard drive than in Mcaffe virus protection, I downloaded another test utility from my hard drive???s manufacturer???s site (Western Digital) and ran it. WD???s utility fixed the bad blocks but, the BOD STOP Error message was still there.

    After spending almost two days reading tons of posts and trying different things, I was more convinced that I had a Master Boot Sector (MBR) virus on my HD. However, no virus checker on UBCD4WIN CD had detected any virus. I couldn???t run Avira virus check du to license expiration issue. After solving the license issue using this post http://ubcd4win.com/forum/index.php?showtopic=14855 (you can also download the key directly from Avira: http://dlce.antivir.com/down/windows/hbedv.key) , I rebuild the UBCD4WIN and once I ran it ,Avira reported BOO/TDss.A boot sector virus (Kaspersky: Rootkit.Win32.TDSS.mbr, Sophos: Troj/TdlMbr-B, MS: DOS/Alureon.A, DrWeb: BackDoor.Tdss.4005). Avira could not fix it but, at least I knew what and where was causing the 0X7B Stop error.
    HOW to fix it.
    1. Boot the PC from UBCD4WIN and run MBRwizard (Start/Programs/DiskTools/Partition/MBRWizard).
    2. Use option 1 just to look at your MBR info. Next use option 8 and save MBR on your hard drive.
    3. Run Avira against saved MBR file. It should detect virus in the saved mbr file.
    4. Use option 7 to wipe MBR or first 63 sectors. When asked to wipe MBR or first 63 sectors, choose ???2??? for just first 63 sectors.

    Exit and reboot PC into Safe Mode (hopefully it will work this time) and run different virus checks to get rid of some other viruses and trojan you may have.
