BIU: "Add to Boot Menu" greyed out

Post by Miss Sophie »

Good day,

I' m having an Asus Z390 mobo and running BIU with one Win10-entry on one SSD-partition on GPT (with EFI system partition). I tried to clone this Win10-entry and adding it to the boot manager of BIU. But this won't work...

I tried to find some help herein the forum, and a thread in this this board mentioned to copy-and-paste the partition in the "work with Partitions" section by making a tick in the "Add to Boot Menu". But this is greyed out and I tried several things to activate it:
- changing the settings in BIU
- deactivate CSM
- activate secure boot with "Windows UEFI mode"

How will I get this box activated/not greyed out?

Edit: I also tried to copy the boot entry manually and change the entry in the BCD-editor (adapting "Device" and "OS Device" in "Menu"- and "Boot"-section)

Miss Sophie,

Can you check this. Select the EFI System Partition, Properties. In the Flags box, do you have a tick in Bit 55? BIU Managed.

Hi Brian,

Yes, the Bit 55 is ticked/checked.

Ok, here´s the next thing: BIU wanted to repair the EFI partition. I confirmed. And after that and the necessary reboot no BIU is there.

Then reinstalling of BIU won`t lead to a "reactivation" but to a reinstall. I did it but nothing happened: still no Bootmanager available (but all discs and CD-ROMs. UEFI is such a complicated stuff...

It's greyed out if:

1) In setup mode (booted from boot disk)

2) BIU is not set to manage the EFI System partition (bit 55 not set)

3) The file system is not seen as a know NTFS or exFAT type. Is it
encrypted? You may have to manually add to the boot item.

Hi,

thank You for your help.

BIU was booted directly from the hard-disc (Samsung EVO 1TB NVMe), bit 55 is set and the Windows partition is NTFS (EFI is FAT32).

Those are the conditions. Is it encrypted? If you view properties /
details does it show free/used space?

Miss Sophie,

While you are waiting to get that item "not greyed" out, you can copy the partition...

In BIU, Scripting

cd \EFI
dir (you should see a Microsoft.001 folder here)
md Microsoft
copy \efi\Microsoft.001\* \efi\Microsoft /s

restart computer

Copy the Win10 partition using Partition Work or Disk Imaging

Restart the computer and there will be a new Boot Item

Edit the new Boot Item to change the Identity
Confirm the new Boot File path includes Microsoft.002
Do a BCD Edit on Microsoft.002

Done.

Thank you for your answer & help!

No, it's not encrypted. On details it shows "Free: 59 MB, Used: 40 MB".

But written as before I'm having now another problem where the BIOS won't provide me the boot options: no "Windows Boot Manager" or "Bootit UEFI". When I reinstall (I can't reactivate it) and reboot, the result will be the same.

Hi Brian K,
also thank you too, for your help & answer!

I never tried to use the Scripting - but it's very helpful! Regarding your steps: I don't have the "microsoft.001"-folder. Maybe that's the problem. Do you know how I can (re-)create it? Yesterday it was there, I saw it...
