Quick Answer

Windows 11 reboot loops happen when BIOS boot mode mismatches partition style. First verify disk uses GPT formatting using recovery command prompt. Enter BIOS settings, disable CSM or Legacy mode, and select pure UEFI boot. Enable Secure Boot and TPM 2.0. Flash latest motherboard BIOS firmware if loop persists.

A Windows 11 reboot loop that starts after a firmware change, BIOS update, CMOS reset, or storage swap is usually a boot-path mismatch rather than a failing component. The firmware is looking for a boot loader in one format (legacy MBR or UEFI/GPT) while the disk holds the other. The Compatibility Support Module (CSM) sits at the center of this mismatch. This guide gives a diagnostic sequence for isolating the fault, converting the disk safely, and deciding when a clean installation is the correct engineering response.

What CSM Does

The Compatibility Support Module is a firmware layer inside a UEFI implementation. It emulates the legacy BIOS environment: INT 10h video services, INT 13h disk services, and legacy option ROM loading. With CSM enabled, the firmware can boot an MBR-partitioned disk by reading the first 512-byte sector, executing the 446-byte boot code area, and chaining to the partition boot record. With
