Solved A Custom PC BUILD setup with Dynamic Disks as Mirrored

THis win 10 PC 22h2 - it was setup with 2 samsugn 1T drives as a mirrored with DYNAMIC DISK and then 2 hard drives spinning disks were also setup as dynamic disks. So not with firmware raid but windows dynamic disk it is believed they used the version that is outdated like the windows 2000 version that is outdated. This machine is having fits with synology nas, and its having problems in diskpart, the 2 samsung ssd drives show a ERROR under the diskpart, and list disk details tells me they are mirrored.
The goal is to make these volumes simple, make them normal make them all regular disks.
Disk manager is showing all disks with a red warning. Macrium is showing them with brown. I was able to make a image of the 2 Samsung mirrored disks. AND I am able to MOUNT this image I made and I copied some files out of this disk and opened them. The image is valid. THE OS is on the 2 samsung mirrored disks. I want to find out if the boot partition actually lives on both or 1 drive. Since the goal is to get the OS on a normal standard disk that is image backup and restore friendly - And the goal is to do this with both of them. I read that a dynamic disk is one thing that all these are setup under one setup. SO the 2 spinning disks are showing a error because any disk in the setup cause effect all others. ? I have never used dynamic disks - many firmware raid 0 and 1 but not Dynamic Disks. Also it appears the amount of data is off its showing 468gig when very little data is on the OS drive. The errors began 11-2025 its error flag shows its hardware. So it could be cables. ? How do I test these dynamic disk setups ? Do I really need to repair the mirror error or dynamic disk error before I unplug one of the disks and delete the mirror or ?? diskmgmnt.msc is the program that is used to create these dynamic disks ? Right ? I have not done this before. So I dont really know how to undo it. The goal is to make all the drives basic disks, open them up for storage and use external drives to backup.

Please post a whole window Disk Manager image of ALL 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.

Also, please post a Macrium image of the mirrored drives.

As you have an UEFI-GPT drive, BIOS transfer the boot sequence to the BIOS priority boot manager on a Fat32 Partition and then to a OS on a partition (same drive or even to a different drive). On the FAT32 partition you may have one or many boot manager (Linux and Windows etc). It is not a serial chain mode. It is a parallel mode.

As both drives are mirrored, all partitions should be on both drives (I never used MS Dynamic disks as they aren't very reliable)

My suggestion is, with Macrium, to make an image of all 4 partitions (EFI, MSR, C: and Recovery), clean the dynamic disks and then, if your MB allow, create a RAID 1 array under BIOS and then restore the image on the RAID using a Macrium boot able rescue disk.

THE OS was on 2 1T SSD drives, dynamic disks was used to mirror it. ONE drive caused it to error out, diskpart showed an error on the two disks. When I removed onedrive the errors also left. I made a image of the mirrored drives 1st off. THat image saved me, that images did restore to a drive and it did boot. Perhaps because they set up this gigabyte as MBR. My goal was to make the disks basic. I could not convert the booting drive of the split mirror because it had bad sectors the disk. Only one disk was bootable in this dynamic disk raid. I was not able to make a image of the single drive that booted from the mirror. Because I did make a image of the mirrored pair first off, THAT ONE did restore to 1 disk and that converted the OS to basic -- On the new disk. HOWEVER it did show up with two boot managers to boot from. IF MBR you cant have two booting partitions or they will cancel each other out so I am guessing the dynamic disk did something to one of the boot partitions. Dynamic disks are not documented well people do not use them much and they do not get along with cloud sync. Also this dynamic mirror of the data drives were having problems with backing up to the synology NAS. Macrium said no to restoring a clone of a dynamic mirror maybe since it was MBR that made it work out. ? Thanks for the suggestion on minitool and AOMEI

Why do you have Win 11 on a boot able drive as Legacy - MBR ?
If you have a spare drive, with diskpart you can prepare a drive as UEFI - GPT and with Macrium you can copy the C: and the Recovery partition to it.
I Can give you detailed instructions.
