I've got Windows 11 installed on a RAID setup using two NVMe drives (MSI Mortar B850). Everything seems to be set up correctly in the BIOS and the system runs great at first. However, after some time, I suddenly get an 'inaccessible boot device' blue screen, which has forced me to reinstall three times now. I suspect there might be an issue with Windows updating the RAID driver that breaks the setup. Even accessing recovery mode doesn't help me fix the boot issue. I can load the RAID drivers through command prompt in recovery, but I can't save this setting to make it bootable again. Can anyone explain why this keeps happening?

Make sure your hardware is compatible, especially if you're using NVMe drives. Sometimes specific models can have issues; I’d check if your NVMe drives are WD Blue, as they surprisingly have a reputation for this type of problem. If yours are both WD SN730, it might not be the most critical issue, but it’s still something to keep an eye on. Additionally, while it's a long shot, ensure that your RAID parameters in BIOS are configured correctly after any updates.
It sounds like a driver issue that might be happening after a Windows update. To troubleshoot, start by gathering dump files, as they can provide insight into the BSOD errors. If you can get into Windows, check the C:WindowsMinidump directory for any crash logs. If you find some, zip the folder and upload it to a file sharing site, then share the link. Those files can be really helpful for identifying the problem. Also, consider switching your dump settings to create small memory dumps if you're not getting enough data. It's a bit of a hassle, but it could give us a better look into what's going wrong!
Always back up your data before making new changes. RAID setups can be tricky, especially with BIOS updates or hardware changes. If the BIOS settings get altered, it might cause issues with your RAID configuration, leading to the boot problems you're experiencing. A good practice is to check your backups regularly and have a recovery plan ready just in case.
