Consider the following scenario:

  • You have an Advanced Host Controller Interface (AHCI) Serial Advanced Technology Attachment (SATA) drive or controller.
  • You receive a new computer that was configured by an OEM to start up into the default Windows Out-Of-Box Experience (OOBE).
  • When OOBE runs, the system restarts unexpectedly. When it restarts, you receive the following error message:

    Failure occurred during online installation. Online installation cannot complete at this time.

  • The computer restarts before you finish OOBE. When this occurs, the operating system will not start. You must restore the computer back to the factory default configuration from the OEM recovery media.

Additionally, you receive the following stack dump entry:

IRQL_NOT_LESS_OR_EQUAL (a)

IMAGE_NAME: msahci.sys
FAILURE_BUCKET_ID: 0xA_msahci!AhciHwInterrupt+17

Note: This issue occurs with OOBE. It can also occur under different circumstances with a SATA controller.
