ggRock Client Machine Blue Screen - "inaccessible boot device"

Problem

The following blue screen appears:

INACCESSIBLE_BOOT_DEVICE

Solution 1

Review theConfigure ggRock Guide, ensuring that your VHD image file was created correctly, including:

• Disable Secure Boot (remove all keys)
• Configure BIOS in UEFI mode (fall back to legacy mode if this fails)(Storage and PXE boot settings)

Additionally, as a troubleshooting step it can be helpful to boot the image in a VM with the following settings:

• UEFI Mode
• Local Drives Mode

Solution 2

Ensure your Windows OS is correctly configured, including:

• Disable Windows Updates (it is important to do this before you make your VHD with the ggRock IC tool)
• Disable Defragmentation

Solution 3

Ensure that the hard drive or SSD has been removed from each Machine.

Solution 4

If your center has Machines with multiple different Network Cards or Motherboards, it is necessary to capture information on the network card from each different Motherboard/Network Card using the ggRock IC Tool. See the "Adding a New Machine Type to a ggRock Image using the ggRock Seamless Boot Procedure" guide for detailed steps.
