System Reserved Partition on Disk 1 not Disk 0

My PC was dual-boot with the 500 MB System Reserved and Primary System partitions on Drive 0 and the Secondary (2nd on added) on Drive 1. Then I started having boot problems which apparently were caused by Disk 0 errors. I would often get "Scanning and repairing drive" notification during bootup. Then Windows went through some extensive repairs during one boot attempt and added a 500 MB Recovery partition in an unallocated area of Drive 1 after the System partition. I think it was called Recovery. Eventually the computer wouldn't boot at all.

Now I've replaced the Drive 0 HDD with a 500 GB SSD drive and completed a clean install of Windows 10 on a New 200 (195.31) GB partition on Drive 0 with the intention of the System Reserved partition being added by the Windows installer before the System partition on Drive 0. That's not what happened, the 500 MB Recovery partition on Drive 1 was replaced with the System Reserved partition. So, I repeated the Windows 10 clean install on SSD Drive 0 and deleted all partitions on Drives 0 & 1 before adding a New 200 (195.31) GB partition on Drive 0 and selecting Drive 0 for the Windows 10 install. Windows again placed the System reserved partition on Drive 1.

Why is Windows insisting on installing the System Reserved partition on Drive 1?

What do I need to do to get Windows to place the System Reserved partition ahead of the System partition on Drive 0 leaving Drive 1 completely unallocated?

Thanks.

I recommend you do any partition after setup is complete. I notice you have split the drive already prior to carrying out the installation.

Do this instead, boot from the install media

Click Install Now

Accept License Agreement

When the option is displayed to select an installation type, click (Custom Advanced)

Click Drive Options

Select the drive then click Delete until there is only a single unallocated partion.

Select it then click New

Click Apply then OK

This will split it in two, a system reserved partition and a primary partition.

Select the primary partition then click Next to begin setup.

When setup is complete and you arrive at the Windows 10 desktop, press Windows key + X, click Disk Management

Right click the drive then click Shrink and follow the instructions to create your partition scheme.

The results were the same as before: Windows is installed in a single 477 GB partition on Disk 0 and the System Reserved is in a 500 MB partition on Drive 1. The rest of Drive 1 is unallocated. This is identical to the configuration I had when I asked the question.

The Media Creation Tool used to created the install ISO DVD is v. 10.0.14393 downloaded on 12/13/2016.

I followed your instructions:

  • I selected Drive 0 and deleted the existing Windows partition.
  • I clicked New and Apply. Windows then formatted Drive 0 as a single primary partition.
  • The existing System Reserved partition was still on Drive 1.
  • So I deleted the System Reserved partition on Drive 1 and the just created Primary partition on Drive 0
  • I then selected Drive 0 and clicked New and Apply again. Same result a single Primary partition on Drive 0. Drive 1 was left unallocated.
  • Upon completion of the install
    • Windows occupies about 15 GB in the only partition on Drive 0
    • The 500 MB System Reserved partition was placed on Drive 1
    • The rest of Drive 1 is unallocated.

How can I get the System Reserved partition to be placed as the Partition 1 on Drive 0 with Windows installed in Partition 2?

Thanks.

That is correct and by design. Here is an example:

Click Custom

Select the drive and click New

NOTE: If you have multiple partitions listed, select each one, then click delete until there is only a single (one) unallocated drive displayed in the window.

Image

Select the unallocated drive listed, then click Apply

Image

Click OK

Image

Select the Primary partition then click Next

Wait while Windows installs

I apologize for my poor communications skills. I followed the steps you'd recommended and show, but for me the System Reserved partition is being placed on Drive 1 not Drive 0. Do you know how I can get the results you got, with the System Reserved in Partition 1 and Partition 2 marked Primary and both on Drive 0?

Keep in mind, as I tried to explain in my question and 1st reply, that there's an existing System Reserved partition on Drive 1 when I enter the "Where do you want to install Windows" screen. What can I do to achieve that?

I first tried to follow the steps you had described and show above, but only one partition marked Primary was placed on Drive 0. So I then deleted everything including the existing System Reserved partition on Drive 1 and deleted the Primary partition just created on Drive 0. 

That left Drives 0 & 1 as all unallocated space, I then selected Drive 0 again, clicked New and Apply. Still what was returned was a single Primary partition on Drive 0. Drive 1 was still unallocated, but the install result, as shown below, has the System Reserved partition on Drive 1.

I can't understand why I'm getting results different than you're getting. In the past I've got the expected (both partitions on Drive 0) result on this same computer, but for some reason, I'm not getting them now.

This PC does have 6 drives and drive 0 is an SSD, but I haven't had this problem in previous clean installs.

Thanks for your patience.

If you have more than one drive installed during setup, disconnect all drives except the target drive where Windows 10 is installed. You always reattach addition disks after setup is complete.

Thanks. I can try that; but I wonder why I haven't had to do that before, and it honestly doesn't seem reasonable to me particularly since the installer provides a "Where do you want to install Windows" selector.

For various reasons, I've clean installed Window 10 on this computer 4 or 5 times over the last year and never had this problem. I even used the same installation media build back in December. Before that, before that, my desktop PCs have had three or more drives since around 2006, and I've installed dual-boot configurations on all of them for XP, Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10 and never had to disconnect other drives that I can remember.

Any idea why this is happening now? There must be something going wrong, I just don't know what it is. Maybe there's a parameter Windows is reading somewhere on my PC to guide the install that's gotten corrupted.

Thanks for your patience.

Bill
