Issue/Introduction

When attempting to PXE boot or iPXE boot to a configuration with custom drivers added, booting fails with 'Could not boot: Error 0x2a818006'

Environment

Deployment Solution 8.x

Cause

Could not boot: Error 0x2a818006 indicates that there isn't sufficient RAM/Memory to load boot.wim created. It was discovered that there were over 7 GB custom drivers added to preboot environment. This caused the boot.wim to grow significantly which prevented booting on models with insufficient memory

Resolution

Remove unneeded custom pre-boot drivers to reduce the size of the boot.wim that is created.

Custom pre-boot drivers need to be removed manually with DS and can be done so with the following KB:

How to remove custom preboot drivers (bootwiz)

Once drivers have been cleaned up, rebuild the affected PXE configuration to remove the additional drivers from the config.
