Secure Boot Option Not Functioning

2021-10-05, 22:34 PM

Windows 11 advises that the bios must be set to "secure boot." Lenovo explains how to do that here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1-carbon-7th-gen-type-20qd-20qe/solutions/ht509044-how-to-enable-secure-boot-on-think-branded-systems-thinkpad-thinkstation-thinkcentre

 

However, following those instructions and rebooting my Carbon X1 6th takes me to the attached screen in an endless loop. The computer will not start normally and exiting from the attached menu simply takes me back to it. The only way I found out of it was to reset my bios to defaults. 

 

Without being able to do this I am apparently unable to upgrade to Windows 11.

 

Solution please?

Re:Secure Boot Option Not Functioning - SOLVED

2021-10-15, 20:44 PM

OK, so I have found the solution, which is a bit modified from my prior post. I went through the steps and my computer is working fine in the GPT UEFI mode. 

 

First step I found through trial, error, and search that Windows 10 does not recognize your Windows password during this process unless your first sign out of Windows 10, then sign in using the password option and using your Windows password. (In other words, if you use fingerprint or PIN this process does not work because Windows does not recognize your password for a key step in this process.)

 

Second step was to follow the steps outlined in the post linked below. Note that they recommend doing this through Windows 10 (the first option listed) and caution that the other option (i.e. just going to a command prompt from the desktop) is not best. They say this about that second option (which is the one mostly promoted on the web): "Converting MBR to GPT from Windows 10 desktop: The MBR2GPT tool was designed to work offline in the recovery environment, but you can also use it when Windows 10 is fully loaded. However, we do not recommend using this method if you want to avoid possible problems."

 

So I followed the first approach (using Windows recovery) listed in the following post to the letter: https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10

 

In short order the drive was modified and the computer booted properly in Windows 10. I confirmed that the drive was converted as explained in the post.

 

Third step: Even though the drive was now modified to GPT and booted UEFI, when I checked Windows Update I still got the message that the computer was not compliant with Windows 11. I needed to take one last step, which was to enable Secure Boot. To do that, I simply followed the original Lenovo advice, rebooted the computer, entered the bios, went to the Security tab, selected the Secure Boot option, enabled it, and exited saving changes.

 

Upon rebooting Windows 10, I checked Windows Update and it stated that my computer is now fully compliant with Windows 11.

Hi

 

You change to secure boot, did you change the HDD at all?

 

You may want to repair W10, the Boot Manager may be looking for an EFI bootable device and not finding it.

 

 

The AUTOMATIC REPAIR is where I would start.

Thanks for this. The Windows 11 upgrade evaluator has correctly identified that I do not have secure boot selected in the bios. I've checked and that is the case. Therefore I followed the Lenovo guidance (linked in my prior message) to change to change the bios to secure boot. That guidance renders the computer unusable, showing the screen shared in my original post. The problem appears to be that the Lenovo guidance is incorrect.

Thanks. Yes it is User Mode. But Lenovo does not appear to allow that option to be changed on that page of the bios. So whether I enable or disable Secure Boot, the Platform Mode stays the same.

Thank you. Here's the issue: I have reset the bios to defaults. I have followed Lenovo guidance to change to Secure Boot. Following the Lenovo guidance allows for the selection of Secure Boot, but then prevents the computer from booting. Either the Lenovo guidance is wrong (incomplete) or the bios needs to be updated to allow for the selection of the Secure Boot option. I would prefer not to try workarounds because I think Lenovo needs to address this.

Hello,

 

Was Windows 10 installed to a MBR-partitioned drive?  If so, that could explain why UEFI Mode Secure Boot fails.

 

Try following these instructions on Intel's support website to convert the drive to GPT partitioning, after which Secure Boot should work:  https://www.intel.com/content/www/us/en/support/articles/000024558/memory-and-storage/intel-optane-memory.html

 

Note that a backup of data is recommended before performing this operation.

 

Regards,

Thanks very much for this. Yes, a basic internet search about converting from MBR to GPT offers many solutions, some of which seem to conflict with each other. What's unclear is if there is any way to do this without having to reinstall Windows and thus essentially restarting from scratch. Lenovo's advice, which I linked above, makes no mention of any of this and therefore seems not only wrong, but basically useless for anyone with a disk that is formatted MBR. In my case, my computer came that way from Lenovo.

 

Since Microsoft is saying that you must have Secure Boot enabled to install Windows 11 and since Secure Boot is only available in a GPT formatted environment and since many, many people probably have MBR formatted drives, it would seem to me that there is going to be a major issue ahead for many people wishing to install Windows 11. My guess is that Microsoft, Lenovo, or others may come up with a solution to this at some point. Hope so.

This is the best discussion of the issue I have found: https://www.techrepublic.com/article/windows-11-prep-how-to-convert-mbr-hard-drive-partitions-to-gpt/

 

This is a great video of a user making the transition (note that it implies that you must have a pro version of Windows 10, but that does not appear to be the case): https://www.youtube.com/watch?v=6ws1viKwckY

 

I would note that I have yet to try this fix as I am concerned that it might wipe my hard drive, even though the aforementioned advise indicated that it will not.
