Oh NO!
As I mentioned, I got it up and running, with windows10 working fine. So I had to change some setting in BIOS (secure boot) to enable the update to windows11. When I updated the BIOS and reboot I was back to start - no display, no bleeps. I've cleared/reset BIOS, but still nothing Now I really am tearing my hair out. |

The only suggestion I have is to repeat the clear CMOS steps I linked before. 10
mins should be enough, I stipulated longer in the guide because it's meant to be a 100% foolproof option. If 10 mins doesn't work you can repeat for a longer period. This is why I never update the BIOS on a working system. I only upgrade when I need to for hardware support. |

I've been building computers for many year (since 1979 -UK101 - look it up) and this is the worst set of problems I have ever had.
Turns out that the monitor has a dodgy DP input (I'm using my own 2nd monitor) HDMI is fine. ?‹So got up windows. However - big however. 1) To update to win11, I need secure boot. I go through the process described by yourselves - https://www.asrock.com/support/faq.asp?id=531 2) But then the system just continually boots to BIOS. and the boot priority list has disappeared. The only way I can get it to boot to windows is to clear/rest bios, but then I am back to step 1 !! What is going on? |

Always something you didn't expect isn't it....
I'm afraid this is where my usefulness ends, I have absolutely 0 experience dealing with Windows 11. All this TPM 2.0, secure boot and other "requirements" put me right off. Windows 11 was the last push I needed to say goodbye to Microsoft. If I had to take a stab at it though, I would guess that the secure boot settings mess up your boot settings for windows 10 and cause the system to POST loop into BIOS. Basically the system is behaving as it would if you had no hard disk/SSD installed when you enable secure boot. My guess would be it's the CSM "Disabled" setting. You installed windows 10 with it enabled in legacy mode so it won't boot with CSM (compatibility support module) disabled now. On the plus side, you are out of the woods hardware wise, now you have software issues.... Google should help here: "Can't boot with CSM disabled" FYI, I am just a moderator here, I don't work for ASRock tech support, just another forum member  Sorry I couldn't be more help.

you are right -the CSM "Disabled" setting.
However if I enable that then I cannot set the secure boot -- catch 22 |

This is a very common issue with people wanting to upgrade to windows 11 vs install
a fresh copy. Your current OS is installed in MBR mode (master boot record), secure boot needs it to be EFI mode. There are several guides on how to convert to efi mode out there. A quick google search popped this one up: https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10 In cases like this our decades of experience actually bite us in the rear a little. A lot has changed Edited by Xaltar - 3 hours 2 minutes ago at 11:08pm |

It's biting me in the preverbial again.
Thanks for the suggestion On using 'mbr2gpt /validate' It comes back as a 'disk layout validation failed' - maybe because windows is installed on the M2: 'drive'. It seems I just can't win this time. |

You could just try a boot medium and attempt a fresh install of windows 10 with
safe boot enabled. I am guessing you don't have any valuable data on the drive yet so no harm in a fresh start. Maybe the simple solution will do the trick? |

I'm afraid your wrong about the 'valuable' data. The hard disc has windows and data from his previous dynasur pc. From which I cloned the windows prog onto the M2:
All is not lost however as I did clone the hard drive before I started. I'll use that to boot from then start the formating and transfer of data all over again. Remembering to format the M2: as GPT -- hopefully - seem to recall saying that a couple of days ago. It's not as if I'd be doing anything else at this time of year! Glad I don't give up easily! |
