Windows Server: KB5122882 reportedly causes boot failure on Supermicro boards with Intel SATA RAID
Summary
One user reported that systems with Supermicro mainboards and Intel SATA RAID fail to boot after installing KB5122882. This is reported by users, not yet confirmed by the vendor; Microsoft has not documented the issue. The cause and the full scope are unknown.
Symptoms
After the update and a second restart, the system shows "A disk read error occurred". The RAID array is reported to be healthy when the system is started from an ISO, and no boot repair option helped.
Affected
- Windows Server 2022 with KB5122882 (OS Build 20348.5622, 8 September 2026); the OS version is implied, not stated in the report
- Supermicro boards X9SCL-F, X11SCW-F and X11SSL-F with Intel SATA RAID configured (single user report)
Workaround

Fix
Not fixed yet.
Recommendation
Before installing KB5122882 on servers with Supermicro boards and Intel SATA RAID, test it on a non-production system with the same hardware and RAID setup. Make sure you have a current backup and recovery media. Check for BIOS and Intel RST (Rapid Storage Technology) driver updates; these are not verified as a fix. Watch the Windows release health dashboard and the Tech Community thread for updates.
