Can't boot from SSD

[Finners]

Just built a system up of parts and went to install Windows 10 from usb.

First problem was it telling me I couldn't install on the drive with an efi install image.

So cleaned the drive with diskpart and converted to GPT format within the windows 10 installer.

Rebooted and install Windows 10 onto the now clean SSD.

The problem I have is the SSD does not appear in any boot list. Either in BIOS or the boot menu you bring up if you interrupt the start up.

Now I'm thinking it's something to do with UEFI or Legacy mode but I've tried switching that around and even switched SATA ports.

Any suggestions? It's like there is no boot partition or boot information on the disk although it's a fresh install.

Specs are
I5 8500
Biostar b360GTS3
16gb ddr4

Did you just do diskpart > clean and then run setup? You don't really need to manually create partitions.

Yep, just cleaned it, then converted it and carried on with the install by clicking next on the drive.

Think it's working now just re-installing again. With CSM enabled from the beginning in BIOS.

I was away doing other bits when I left Windows 10 installing and after trying a few time to re-install windows I was getting BSOD's so think I have other issues going on.

I switch to a single stick of RAM from another kit although I know the first set is good.
