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:
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.
When multiple PCs are affected
If several PCs blue-screen and then enter the BIOS, turn the affected PCs off and test one machine first. Try booting that machine from a previous system image snapshot. If it boots successfully, reboot additional PCs to confirm whether the snapshot resolves the issue.
Also compare the BIOS configuration of a problematic machine with a working machine, particularly for BattleArena units. If the machines use different motherboards or network cards, capture each hardware type in the ggRock image with the ggRock IC Tool.
