Windows 10: Storage Reserved Partition Error

I just built my first PC and am now running into some problems I could use some help with. I initially installed Windows 10 from a USB onto my SSD (Samsung 850 EVO 250gb), but also had my WD Blue 1TB HDD installed. The storage reserved partition was erroneously installed onto the HDD. After researching the issue, I did a clean install of Windows onto the SSD with the HDD disconnected. This has led to two new issues:
1. The SSD does not show a storage reserved partition.
2. The HDD is not recognized in BIOS or Drive Management while the SSD is connected.
I launched the Windows installer with only the HDD attached and found the original storage reserve partition still existed. I removed that partition, but the unallocated space did not increase. I'm not sure how to proceed. Thank you.

C Drive Error

While it's not advisable to have the Paging file on the system reserved partition, it is large enough that you can leave it there for now and focus on removing files off of C to storage. Report back how performance is or any errors as you go

 

cannot locate system reserved partition on Disk Management

This Windows 10 upgrade error is usually caused by insufficient space on the System Reserved partition. When you install Windows to a partitioned MBR disk, Windows will create an additional partition without drive letter labeled as System Reserved, which
stores important boot files and normally locates before the system partition (often known as C: drive). On Windows 7, it often takes 100MB disk space, 350MB on Windows 8, and 500MB on Windows 10. Since upgrading to Windows 10 needs more space on the System
Reserved partition, Windows 10 will not upgrade unless it detects that the System Reserved partition has enough space. If you fresh install Windows 10 to a specific partition, you won't receive this error. By the way, the System Reserved partition first appearance
was on Windows 7, so you won't have this error on previous versions of Windows.

To solve this problem of being unable to update System Reserved partition, you can increase the size of System Reserved partition using third party free partition software like AOMEI Partition Assistant Standard, which can manage your disks and partitions
without data loss.
