Your partitioning looks like a MBR format, no big deal but GPT can be more advantages.

As you have a backup of all your data what you could do is to not delete all partitions and choose partition C: to install Windows on. What I would do is delete all partitions on disk 0 and perform a clean installation without any other storage device connected. Removing all other storage devices is important to prevent installation problems such as partitions on the wrong device, I've recently seen it happen that on 1 other storage device the recovery partition was installed on because it was connected while the reinstallation took place.

so where do you think a reinstallation of windows will place the Windows old folder?
Normally a reinstallation is done on the C: partition where an installation is already present on, this makes that the C: partition will get the Windows.Old folder. If you would do the installat ion on a different partition where no current installation is present the Windows.Old folder won't be created.

Just to clarify. the snippet you see is from my laptop and disk 0 is my laptop HDD. i was unable to run disk management from the desktop drive due to the inability to boot to windows. So disk 1 is the clone from my desktop system attached to my laptop via usb .

No problem, this one probably still helps :)
What you could do is not delete all partitions and choose partition C: to install Windows on.

A new installation will create all partitions the system needs for MBR or GPT.

sorry just so i am clear, the new installation will create all the partitions needed but will it also delete all the current partitions or will they remain on the drive?

For example, when installing Windows the following partitions will be created
  • C: partition, Windows partition
  • Recovery partition
  • EFI partition, partition for the boot

When creating 2 partitions from the C partition and you reinstall on the C partition the second will be unharmed.
When creating 2 partitions from the C partition and you install on de second you create a dual boot where 1 won't boot in your situation.

Sorry i am still a little confused Im an older user and sometimes need the See Spot Run version.
in the two statements you mention the c: partition, in the first statement you indicate the the second would be unharmed. does that mean it creates a new partition # and receives a new drive letter?
In the second statement you mention that the c : partition may create a dual boot.

Being kind of a slow learner I just want wrap my head around this.
So normally an MBR formated HD can only have 4 partitions but can create an extended partition. so curently i have a disk with c:, (partition 1) the reserve / d: (partition 2) the Os / and e: (partition 3) data storage. So on the install, will it create new partitions or just write over the old. and if it creates new partitions will it automatically create the extended partition . and if it does not overwrite the current partitions, will all the data files that currently reside on the os partition be left untouched. ( this will make moving them a little easier.)
Sorry if I am kinda dragging this out. ( In the 35 years i have had computers this is first bsod that i have been unable to resolve)

The new partition would be created by the user, the setup cannot create such a partition.

My example is for GPT format, MBR format is different.
I've marked the partitions that are created when installing Windows per format.
GPT format:
