Hot Take:

Who knew that the path to fixing dual-booting issues in 2024 would take longer than making a 5-star lasagna? Microsoft finally resolves the Secure Boot kerfuffle – and just in time to disrupt the nine-month anniversary party of frustrated Linux users.

Key Points:

  • Microsoft fixes a Secure Boot issue affecting dual-boot systems after nine months.
  • The issue was caused by an SBAT update targeting vulnerabilities in UEFI shim bootloaders.
  • Users encountered boot failures with error messages after the August 2024 updates.
  • A temporary workaround was shared before a permanent fix arrived in May 2025 updates.
  • Future updates will avoid automatically applying the problematic SBAT update.
