I switched from Windows to Linux, but after less than a week I realized I'm not comfortable enough with it and want to return to Windows. I followed an installation tutorial, but I can't find my product key. When I try to continue without entering one, the Windows installer says the drive is offline or doesn't recognize the hard disk. What should I do?

You usually don’t need to locate the product key manually. On computers that originally came with Windows, the key is often stored in the firmware, and activation may also be linked to your Microsoft account. During setup, choose the option to install without a key and activate later. If the machine had a separately purchased license, you may need that key or the account it was linked to.
If the disk still doesn’t appear after removing the Linux partitions, check the computer’s storage settings. Some systems use Intel RST or VMD, which can require a storage controller driver during Windows setup or changing the related firmware setting. Download the correct driver from the computer or motherboard manufacturer on another device and load it with the installer if prompted.
For a clean reinstall, create the Windows USB with Microsoft’s official installation media tool, boot from it, and use the custom install option. Be careful: completely wiping the drive means losing Linux, personal files, and any recovery partitions. If you only want to test Windows first in the future, a virtual machine, live USB, or dual-boot setup is safer.
The installer likely needs the drive prepared before it can use it. Boot from a Windows installation USB, choose the custom installation option, and remove the existing Linux partitions so the space becomes unallocated. You can then select that unallocated space and let Windows create the required partitions automatically. This will erase the data on those partitions, so back up anything important first.
I tried skipping the key, but the installer still doesn’t seem to recognize my hard drive.
