Can BIC or IFW convert an image from legacy BIOS to UEFI w/ Secure Boot?

[timg11]

Can any combination of Terabyte tools (IFW and/or BIC) convert a Windows 10 system (image or in-place) that was installed to run on legacy BIOS into a system that uses UEFI BIOS with Secure Boot?
This change appears to be necessary to upgrade to Windows 11.

Are there any KB articles or FAQ's on the process?

timg11,

Not necessarily. I have two MBR computers running Win11 and it runs fine. Win 11 24H2. One was an upgrade and the other was a clean install.

Otherwise, you can use...

@Brian K, I wasn't asking about MBR vs GPT disks, but about legacy BIOS vs UEFI with secure boot.
I've searched on whether Legacy BIOS requires MBR partitions and vice-versa. Google says "When deploying Windows to a UEFI-based device, the hard drive that includes the Windows partition must use a GPT file system. "

So I'm assuming your Windows 11 MBR systems are running Legacy BIOS and are not using Secure Boot.
So if I wanted Windows 11 with Secure Boot, that requires UEFI and therefore I would need to convert the Windows boot drive from MBR to GPT.
Then change the bios mode to UEFI.

UEFI uses GPT, legacy using (E)MBR, you'd use chgdtype.tbs and then change BIOS setting (of course it needs to be a windows version that supports UEFI, which of course Win11 does).

timg11,

My Win11 "MBR computers" are using Legacy BIOS with EMBR and MBR disks. There are no GPT disks.

But I do prefer using UEFI firmware with GPT disks for Win11.

I was merely pointing out Win11 doesn't necessarily need to use UEFI firmware with Secure Boot enabled.
