I am stuck with a weird problem here. I am trying to install Windows 10 on an "old" Windows 7 desktop machine for a friend. I purchased an SSD for him, but when I try to install Windows through USB it says:

> 
> We couldn't create a new partition or locate an existing one. For more information, see the Setup log files
>

I have tried:

* Converting the drive to MBR and GPT
* Diskpart -> clean -> create new primary partition -> mark as active
* Remove all CD, SD, etc. drives from the motherboard (they don't appear in BIOS)
* New SATA cable
* Plug SSD into USB adapter and partition the drive on my desktop and mark it as active

However, none of these worked out for me. Very weird. Therefore I want to install Windows on the SSD through USB through my PC. I have a couple of SATA to USB adapters (with power and everything), so the drive basically appears as an USB drive in Windows. How would I go on about installing my Windows ISO on this drive through USB, without screwing up my partitions on my desktop PC?

What I have:

* Windows ISO
* USB adapter to hook up the SSD to my desktop

Let me know what the best approach would be, to solve this issue would be. Thanks!
