Multiple Boot Partitions after Clean Install of Windows 10

[ToastedCrumpets]

After performing a clean install of windows, I am prompted to select which OS I would like to load on boot. I'm not sure why multiple versions of Windows are detected. Here are the steps I followed:

1. Created bootable USB drive using Windows Media Creation Tool.
2. Shut down PC.
3. Unplugged all HDDs/SSDs except for the drive I want to install Windows on.
4. Turned on PC, booted from USB.
5. Format my intended boot drive* following Windows installation dialogue.
6. Clean install of windows.
7. When I boot, Windows asks if I want to boot either:

• Windows 10 (on volume 3)
• Windows 10

Why am I seeing two options?

 

*I can see multiple partitions on my intended boot drive:

1. Drive 2 Unallocated Space
2. Drive 2 Partition 1 (Type = System)
3. Drive 2 Partition 2 (Type = MSR (Reserved))
4. Drive 2 Partition 3 (Type = Primary)

 

For context my system has the following drives:

1x NVMe SSD (intended boot drive)

2x SSDs in RAID ZERO (intended to store games)

2x HDDs in RAID ONE (intended to store documents)

Those are pretty normal partitions. I do have the same partitions. You have those on most when not all installs since windows 7

Thanks, so the partitions look normal. Any reason why there are multiple instances of Windows being detected?

Was/is Windows installed on any of the other drives?

The best practice is to choose a custom install, then delete all existing partitions on the drive, then choose the unallocated space as the install location. Windows will create all necessary partitions during the install.

Yes, the NVMe SSD is a relative new addition. Previously, Windows was installed on my SSDs in RAID 0.

 

Here're the steps that I've taken, this seems to have fixed my issue!

1. Deleted and re-created my RAID 0 volume.
2. Unplugged all non boot drives.
3. Performed clean install of windows.
   1. Deleted all partitions from my boot drive.

In the future, I'll make sure to delete all partitions from my boot drive before installing. Thanks for your help!
