Hi SuperUserOX,
Welcome to Microsoft Community.
Based on similar cases from different communities, your speculation is a possible direction.
The Blue Screen of Death (BSOD) you're experiencing after setting up RAID1 and restoring from a backup image could be related to the situation that the backup image was created from a Windows system with no RAID configuration.
When you restore a system image to a RAID array, the system expects the RAID drivers to be present.
If the original system did not have RAID configured, the necessary RAID drivers might not be included in the system image. This could cause the system to fail to boot, resulting in a BSOD.
I wish I could provide more detailed analysis, however, analyzing issues related to RAID requires deeper knowledge of the principles of redundancy, data backup and recovery technologies, which is beyond our technical reserves.
The issue on RAID is out of reach of the response support community. For further professional assistance, it is more suitable for publishing on Microsoft Learn (English only), you can click on "Ask a question", there are experts who can provide more professional insights in that place.
Here is a link to the forum where you can raise specific scenarios and share your idea to help analyze the problem.
Thanks for your patience and understanding.
