Acidentally overrode the primary partition on my Aspire A315-24P while installing Windows 10

Hi everyone,

While I was installing Windows 10 on my laptop I accidentally formatted the manufacturer partition on the internal storage disk, I didn't read the popup and just clicked OK. The laptop now doesn't recognise this disk even in BIOS.
How can I recover the disk or reset it to factory settings? (I can live with not being able to get my data back)

Remove your boot drive and mount it in an external USB case or connect it to a USB adapter-cable, plug that in a USB port of another Windows10 PC and copy what files you can recover. After that initialize and format the external USB drive: https://learn.microsoft.com/en-us/windows-server/storage/disk-management/initialize-new-disks
Reinstall the empty initialized drive in your laptop and Clean Install Windows10 the way you did before or follow this tutorial:

The way data is deleted is that only it's memory addresses are forgotten, and new files eventually overwrite those addresses. So most data can be recovered using some softwares.

If you can't boot then you will have to create a Bootable drive either for windows or Linux from another device . These can be purely installation ones or "live" ones which allow you to use the OS without installing it. From here you can use disk management software. Remember, if you want your data back then before you do any actions on that disk it's recommended to back it up or clone it because once you start working on the disk data can be overwritten.

Always remember to do any work on the disk and partitions very carefully with backups in place. This is deadly stuff. Also many times new disks won't show up in windows even after plugging in, you have to check disk management for those.
