Unable to boot - Safe Mode stops after crcdisk.sys

Anonymous

original title: Windows Vista 32-bit crashes as system is loading. Safe mode hangs after crcdisk.sys loads.  System restore also fails.

My computer (an HP m9200t) no longer fully boots after installing a new windows update.  When turned on the computer will begin to load windows and allow me sign in.  However, about 30 seconds to 2 minutes after signing in I can no longer interact with my desktop (although I can interact with programs that automatically load upon startup, like windows live messenger).  I sometimes receive a screen that says "kbd.exe failed to initialize properly".  I have tried to restore my system to a point before the update loaded, but I am told my file system is corrupt.  When I run a system diagnostic, I am told there is a problem with one of my hard drives.  I have also tried to boot in safe mode, but the system hangs immediately after loading crcdisk.sys

    I had the same Vista boot problem even in safe mode: the boot sequence stopped at the crcdisk.sys phase and blue death stuck with error message 7B. Many previously suggested solutions were tried, in vain. The solution came from here: http://www.askvg.com/how-to-change-sata-hard-disk-mode-from-ide-to-ahci-raid-in-bios-after-installing-windows/   . In the windows registry the SATA hard disk mode changed somehow (?) to IDE. So I had to change it in the bios setup to IDE, now the Windows started up normally, I changed the IDE mode manually in the registry to AIHC, and then while rebooting, in the boot menu back to AIHC.

    I suspected that the AHCI setting in the bios had something to to with it, but when I tried changing it to ATA i got an error message saying 'drive not found' or something of the like. I then tried changing the setting from AHCI to ATA and then reinstalling, and apparently this solved everything, because I reinstalled Vista Home Basic without any error messages and it seems to be working fine.

    My Vista started showing blue screen at loading crcdisk.sys during boot and went into a boot loop. Thank you for bringing my attention to this BIOS setting. I changed the setting from AHCI to ATA and it worked for me.

    When I started the machine after several days, I was prompted with an option at boot to load default BIOS settings. I don't know why that prompt came up, but I suspect that caused the BIOS setting to go to AHCI where it should have been ATA.

    Hi There,

    The default bios settings is often triggered by the motherboard battery getting a bit tired.

    Especially if the machine has been off an unplugged for a few days.  This can happen if the "Power Police" turn off everything at the wall socket. While the machine is off at the wall the bios settings are maintained by the battery.  While the mains power is connected even with the machine turned off the battery is not used so will last years longer.

    Desktops batteries are usually fairly easy to replace with a clearly visible coin sized battery on the Motherboard.

    Notebooks a little harder depending on the model and your skill levels as you have to get the case apart and the batteries are not always standard sizes.

    Glad you got your machine going again.

    David

    This is a crazy thing that happens.  I have gone down the list many times with this crcdisk.exe, failure.  What fixes it every time is to pull the RAM out of the computer and put it back in again.  High Tech solution for an issue no one seems to understand or provide a permanent fix.  "Elbow Windows Tech Support"

    I believe you hit on your issue.

    replace your memory sticks.  Make sure the ones you put in are the proper speed as in the PC's specs.
