Clean Install of Windows 10

HP ENVY Phoenix 810-150ea Desktop PC (ENERGY STAR)
Microsoft Windows 10 (64-bit)

Hi,

I have a Hewlett-Packard 810-150ea with a SSD and a HDD, running windows 10 1903 (came with Windows 8.1). I need to perform a clean install of 1903, but there appears to be conflicting information on the internet of how to do this. I have downloaded 1903 on a flash drive when I attempt to install 1903 I selected to perform a Custom: Install Windows only (advanced) I am asked if I want to delete any partitions, I have 6 on drive C (drive 0) Windows RE tools, EFI Windows (C:) and a 785 MB OEM Partition and a 450 MB OEM Partition. Should I delete all of the partitions? I have read the EFI is to enable the PC to boot from different drives and should not be deleted.

Also can I move the Recover image to the HDD to give me an extra 10.15 GB of space on the SSD drive?

Thanks in advance.

Your Recover image is now useless -- as the Upgrade to Win10 is known to corrupt it.  So, if you DO decide to do a clean-install, you should first remove the Recovery partition to reuse the space.

Clean Install of Windows 10

Hi WAWood,

Thanks for the reply.

When I perform a clean install of Windows 10 (1903) can I delete all the partitions including the EFI system partition? I have read the EFI system is used to enable the PC to boot from different drives and should not be deleted.

Thanks again

The EFI partition is what allows the PC to boot -- in this case, into Windows. Do NOT remove it.

The Recovery partition is now useless, so you can remove that.
