You're making everything more difficult then it is.
Good luck

I'd appreciate any advise on how to make this easier. How do I unhide the data partition of the 1T drive. This is the main problem I need a solution for.

I already made the boot partition active on this 1T drive. Everytme I've been rebooting I lose the drive letters like F. Do you think since I made the boot partition active that will fix my data partition being hidden? Thanks for all your help

There is no active partition on drive 1 so it won't boot.

Just for clarification, this is true for MBR disks. For GPT, you don't need to mark a partition as active or have any partitions marked as active. That concept no longer applies to GPT.

My advice is to use Macrium Reflect and start over.
Clean the drive. Don't format it.
Open a CMD window as administrator and type:

diskpart
select disk 1
clean
convert mbr
exit

Drag and drop the partitions you want on the new drive from source to target (drive 1).
When you finish, use the commands I gave to make it boot able (replace G with the drive letters on the Windows partition).

Thanks for the advice. I'll open CMD window as administrator and use your instructions on that. . I'll delete all the partitions, unless the CLEASN command already did this. I'll then create the boot partition, recovery partition, data partition. I'm not sure what to do with the recovery partition, so I'll just leave it blank. I'll restore the boot partition I made today to the 1T boot partition and make sure it's active. I'll probably do this part with the 1T HD in my other computer. How does this sound?

I plan on doing this tomorrow, wednesday. Unless someone has a solution for unhiding all the partitions on my 1T HD. That's really the only reason I have to use these extreme measures to fix this. Every time I reboot I lose the drive letters and network sharing on my 1T HD

On a MBR drive:
- System partition - NTFS - 100M
- C: partition - NTFS - 80G (if it will have no data, otherwise as big as you wish)
- Recovery - partition - NTFS -1G
- Data Partition - NTFS - As big as you wish

On my main computer - System partition - NTFS - 350M and the Recovery - partition - NTFS -522M. These sizes were from Win 8.1 with an upgrade to Win 10. Should the Recovery partition really be that large at 1G?

Since I don't know what to put in those partitions, I'll leave them with no files. When I restore the Macrium image I'll only restore the C drive not the system partition or Recovery partition.

I'm going to do all this on my main computer with the 1T as a USB drive and I'll make sure the boot partition is active after I do Macrium, which is installed in Win 10 on this computer.

Does this all sound right?

Thanks for all your help.

You don't need a System partition with more than 100M. Big system partitions are from OEM (HP,Dell, Lenovo etc) where they also have tools and factory recover.
Yes, you need a big Recovery partition so make it big as 1G

Since I don't know what to put in those partitions, I'll leave them with no files. When I restore the Macrium image I'll only restore the C drive not the system partition or Recovery partition.

A computer with system partition should have that partition active, not C:.

Just create the partitions and I will instruct how to load the boot manager on the System partition and create a recovery environment on the Recovery partition.
If you tell me how big you want the C: partition I can give you the instructions to create the partitions with Diskpart.

C partition 75G. I'lldo the rest like you said

Everything is a real disaster.
- Your "Diskmanagement“ screenshot is not as it should be.
- If you know how to use Macrium the right way, s.th. like that doesn’t happen.
- The reason why you have to reassign a driver letter after each reboot is probably just a wrong partition ID
- In domain computers a a simple startup-script mounts the server drives to the PC with the correct drive letter
- Why don’t you use the Microsoft Partition script for your disk layout
- Even on an old plain BIOS/Legathy computer you can use GPT-Disks
- and so on ...

check partition ID
diskpart
sel disk 1
sel par 3
det par

In det par output

type = 07 ?
only if not !

set id=07 override
assign letter=F
exit

reboot and check if the drive letter is there
