Can you let us know the exact model number of your laptop. Do you know if it contains a Hard Disk Drive (HDD) or a Solid State Drive (SSD).
Really old laptops contain HDDs, more recent laptops contain 2.5" SATA SSDs, but modern laptops usually contain M.2 NVMe (or possibly SATA) SSDs.
If you're unlucky, your drive is failing and may need to be replaced. If you can still boot into the operating system, back up all important files to an external drive or a USB stick immediately.
