"Setup was unable to create a new system partition...."

I've been trying to install Windows 7 from a USB drive on a new HP laptop and I've ran into some problems.

There are 3 partitions listed. One is called HPDOCS, 7gb and is listed as primary. The second is also at 7gb and is listed as system, and the third was unallocated space with 920~ gb.

After some research, I've decided to try out the whole cmd "diskpart" thing. Furthermore, I've tried making my drive bootable by copying the installation files on it and installing directly from the drive, but after trying the " xcopy d: c: /e /h /k " command, I receive the message that there are no files to copy.

And lastly, after restarting and trying again, now I only have 1 partition, 930~ gb, and listed as system. Did I mess something up? Was something essential deleted? Can it be reverted?

Help is much appreciated.

Welcome to the forum. Start the install when it asks were to install you have the option to delete paritions do that then let windows create new ones

So I delete that one partition I have left and the next time I run the installation I'll be back at the three initial ones?

I hope you did the Factory Recover disks before you cleaned all the disk.
You didn't gave us your hardware specifications so it's impossible to us to guide you.
On some new laptops, it's even impossible to install Win 7. They allow only Win 10 and Linux.
If your laptop came with Win 8 or 10, you also have to change some BIOS settings (like secure boot, fast boot, CSM).
Please edit your profile with all hardware information.

No, if you delete your entire drive to unallocated space, then install Windows 7, you will end up with 2 partitions.

It's a brand new laptop, there's nothing to delete is there?

If this is a GPT disk and you are installing in uEFI you will then wind up with 3 partitions.

I'm pretty sure it's BIOS

Not sure why you are trying to install Windows 7 in the way you describe in your 3rd sentence.

I've tried doing method 3 from this article "https://www.partitionwizard.com/partitionmanager/setup-was-unable-to-create-a-new-system-partition.html"

Why was that important?

It's an HP 250 G4. It didn't come with any OS. I'm not sure which exact hardware specifications would be of use to you here.

All I know is that there were 2 partitions - system and HPDOCS and 1 unallocated space option. I clicked on "new" on unallocated space option and created partition 3, and it displayed the message in the thread title.
After trying the whole create partition, clean, active, assign and format, I only now have one partition that's listed as system. It's like the initial three options merged into 1.
