If you're using fdisk you're using a BIOS partition table. Depending on UEFI settings, you need a GPT partition table.
The Fedora installer detects UEFI, and then decides to use a GPT partition table, and look for space.
I've had that on a work laptop (also an HP). You can try to disable secure boot in the UEFI screen, or you can try and tell the USB stick to treat the laptop like a BIOS machine.
The problem is that changing those settings now will break the existing Windows install.
I can't remember the exact setting, but Fedora USB sticks have a valid Secure Boot partition, so the laptop boots from that valid partition, and enables Secure Boot. From that point on, you need a GPT disk.
