Please post a whole window Disk Manager image of your drives. Don't forget to expand the columns so we can read them. How to Post a Screenshot of Disk Management
If you have a MiniTool or AOMEI Partition use it instead or Windows disk manager.
Converting from Legacy-MBR to UEFI-GPT is the first task to achieve.
Upgrading from Win10 to Win 11 is another task that can only be done once you have UEFI-GPT.

This is after most of the drives are disconnected.

A lot of folks are trying to help you. You need to post the pics that are asked for... HOW they are asked for.
Here's some examples...
We need to be able to read the items in the RED boxes...

Your drive is still Legacy-MBR. It hasn't been converted to UEFI-GPT.
Follow this steps one by one.
Open a CMD window as administrator and type:
-Shutdown, detach (SATA or power cable) of ALL other drives from MB. Leave only C: attached.Code:reagentc /disable. diskpart select disk 0 select part 3 delete part override select part 2 delete part override exit
- Boot from Win 10 or Win 11 installation drive. At the Windows Setup screen, press Shift+F10 simultaneously to open a command line prompt. Type:
-ShutdownCode:mbr2gpt /validate (If everything is ok run) mbr2gpt /convert.
- Change BIOS mode to UEFI.
- Boot the drive as UEFI.
- Run Reagentc /enable
- Shut down and attach all other drives to the MB

Since @JerometheGiraff refuses to follow any of our instructions completely, we really can't tell. Here is what is interesting. In the screenshot of disk management, post #33, there is no partition marked as active. Since there is no active partition, we must assume the computer is booting from C: drive in UEFI mode, which is not an impossibility. However, there is no indication in disk management whether the drive is GPT or MBR. The disk could be either one, we don't know, because @JerometheGiraff refused to run diskpart, list disk, which would tell us for sure.
If you squint really hard and look closely at the screenshot in post #11, you will see C: drive is marked as active, but in post #33 it is not. I would officially declare this to be a train wreck at the moment.

The question is:
- If it has no Active partition, how is it booting a MBR drive?
- If it has no EFI partition, how is it booting a GPT drive?
The only explanation is that JerometheGiraff has used one of those applications to convert a MBR drive into a GPT drive and now has an un boot able drive.
Open Disk Manager
-Under View select Top - Disk List

GPT is not required to boot in UEFI mode.
Some computers will boot from NTFS in UEFI mode, most won't and require a FAT partition to boot in UEFI from.
