Unfortunately, there are a few computers with firmware that does not properly handle a shim with two signatures, and some ASUS computers have this problem. It is signed by Microsoft and it is signed by openSUSE. I used to have that problem with a Lenovo, but a BIOS update fixed.īooting linux with secure-boot depends on shim (the file “shim.efi”). This is a known problem with some computers.
“ Invalid signature detected, check secure boot policy in setup.” Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.On the Notebook Asus UX301LA, when giving the boot with the pendrive openSUSE Leap 15 KDE has the following message. Please read the Note carefully, but if you do have problems with the BIOS you can select the option to reset it to the Defaults. Modifications of the settings are at your own risk. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. You may contact the computer manufacturer for further assistance if this doesn’t resolve the issue for changes in BIOS (Basic Input/output system). Note: Refer Disable driver signature enforcement in the link above. Method 2: Disable driver signature enforcement. Disable the secure boot option and check. Restart the computer keep pressing the Boot menu option key to enter the boot menu. When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be any of the function key (eg: F12). I would also suggest you to disable the secure boot and check. Here are some suggestions that I found on the Microsoft Community you should try:
