I wish to install Windows 11 on a Asrock B550 - PG Velocita, but, it will not install because of secure boot. When I try to enable secure boot it says to disable CSM. When I do that the computer keeps booting back into the BIOS. I have to reinstall the UEFI to the BIOS to get it to work again. Please help. Thanks for any replys. ------------- Bob Erickson |

so if you disable CSM and save and exit, CSM gets enabled back? that means some of your hardware is not uefi compatible ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

To KERBEROS_20, You were right. It was the formatted hard drive. Installed a different hard drive worked like a charm. Down side is that I had to reinstall the operating system and almost lost everything. It works now. Thank you for your suggestion. ------------- Bob Erickson |

you could use mbr2gpt tool from windows boot media to convert your drive to uefi, without loosing any data ------------- http://valid.x86.fr/diq4l4" rel="nofollow"> http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |
