Corrupt or missing iastor.sys?


  • Status: 0x00000e9

    Reinstalled Windows 7 from factory restore.  I'm getting this error and it keeps directing me to insert the installation disc.  Won't boot in safe mode or any variation. 

    How do I get past this?

    Unless there is problem in BIOS, check your hardware, namely HDD and RAM.

  • Hi,

    If this is retail version, please move on the next step to perform an In-Place upgrade to repair system to check the result.

    How to Perform an In-Place Upgrade on Windows Vista, Windows 7, Windows Server 2008 & Windows Server 2008 R2

    If Windows 7 came preinstalled on your computer, your computer manufacturer might have included other recovery options. For more information, refer to the documentation that came with your computer, or go to the manufacturer's website.

    In addition, please also check the hardware problem.

    Hope this helps.

    The  OP has already stated that they have done a factory refresh - therefore it's a preinstalled OEM edition.

    The OP has already stated that they are unable to boot the system- tehrefore a repair install is not an option.
