Malware or Tampering: Malicious software may attempt to tamper with the boot process to gain unauthorized access to the system. These nefarious entities can manipulate boot files or inject malicious code, leading to Dell secure boot violation invalid signature detected error.
BIOS/UEFI Settings: Misconfigurations in the Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) settings can also contribute to secure boot violation.
