Windows 10 Installation on a SSD error: “ We couldn't create a new partition…”

Question

I have an Acer Nitro 5 with a Gigabyte 512gb ssd and a WD 1TB hhd. Recently after installing Ubuntu on my hdd (because i didn't want to change the sata mode), I also wanted a clean Windows install. So I created a boot usb from media creation tool and go forward with it. It didn't work. I got the "We couldn't create a new partition or locate an existing one" error, which i spent a significant amount of time trying to search for a solution.

Stuffs i tried: - Format my ssd - use diskpart to clean, convert my ssd partition table to gpt, etc like every guide online recommends. - Make another boot usb, this time with rufus. Didn't work.

Stuffs I didn't try: - Temporarily disconnect my hdd. I don't have the tools to do that physically, and my acer uefi has zero options regarding this, like most guides suggests. - Change to bios-legacy boot mode. There's no option in the uefi.

I think it would be fine if i try to install windows on my hdd though, but haven't try it yet. All I know is installing windows on a ssd is much harder but didn't expect it to produce this much annoyance.

I heard there's an option to install on a HDD, the. use a third party tool to copy it to a SSD, but i haven't look into it.

Thanks for any help given..

Assuming you have Windows 10 installed and working on your SSD go to Settings > Update & Security > Recovery > Reset this PC > Get started and then select if you want your files kept you want clean reinstall. Again - from your post I assume the latter so just click Remove everything" confirm and wait. It will take (depending on the machine) 1-2 hours.

I've found this to be the easiest way to have clean install without wondering how do I get it installed on my laptop/pc.

My recommendation though - back up your ubuntu partition - I can't guarantee that windows installer won't clean up HDD you have (it's supposed to clean only SSD but better be safe than sorry).

Here's the link to detailed instructions . It's based on 1903 compilation - if your's older it will still look very similar.

If your windows isn't working then use diskpart to clean the drive, boot the computer from USB windows installation stick and choose the drive for your installation - it will/should create appropriate partitions and start installing.

If it won't change boot order so the SSD is first on the list and HDD next and repeat the previous step.
