reinstalled win10 on new drive & cant see system reserved partion.

Background.
My old HD (disk 0) is looking faulty so I installed a new drive (disk 1) and did fresh win10 install. I left Disk 0 in PC to test/reformat etc.

I now want to partition new C: drive so I have a separate smaller boot partition for cloning/ win reinstall but am puzzled to find that there is no system reserve partition showing in disk management? I've just read on help sites that it should be there. Is it possible it installed to disk 0 instead?

Should i start again and repartition properly and reinstall win10. Its no problem to me as have little programs and data is all backed.
I have to say i don't recall win10 install giving me an option to do that when i installed 2 days ago (old windows versions usually did)
OR can I partition C as it currently is if i find some clever software? (have added s.shot)

thanking folks in advance!

I would remove all physical drives from the PC, disconnect their power/data leads, then install Windows to the new drive, do not make any partitions first, Windows will create all needed partitions. Once Windows is installed and you reach the desktop you can either shrink the Windows partition and allocate spare space as new partition or use a 3rd party app to do that. There are a few free apps for partitioning recommended on this forum.

Disk part shows it.

Agree, that is becoming one of the more common situations/themes with clean installs/drive changes. I even got caught with it a few weeks ago on an older computer with a RAID/AHCI setting in the BIOS that Windows decided to use the RAID since there were 2 drives attached. Later removal of the D: drive broke the booting process, solution was to remove what should have been the D: drive and clean install again.

@Tanya,

When you are at the screen above with Drive 0 and 2 partitions listed, do the following:
Press Shift + F10 to open a command prompt Window (note: you might have to press Shift + Fn + F10). Run the following commands:
diskpart
select disk 0
clean
exit
exit

Then in that same window with the drives and partitions, click refresh. Highlight the unallocated space that will show up and click next.

The error message you are getting is because the entire drive is filled with partitions and it cannot create an EFI System Partition. The clean command will delete the existing partitions, so then there will be free space on the drive in which to create the EFI System partition (along with all the other required partitions).

Hi- will try that now.

I have also switched the cables correctly inside the PC as i read there was a colour coding system for cables/motherboard

oh my gosh my motherboard cable switched fixed it! when i tried again there was only one partition and no error message.
windows now installing!!

( checked on HP forum and seems like older desktops done recognise faster SATA unless plugged into the main dark blue port). Windows is now loading (so relieved- thanks everyone!)
