Wreck your PC without a CD drive?

I want to get rid of my laptop, I still have a few euro in it.

Data is backed up, now it should be flattened.

DBAN helps, I googled, but a CD is supposed to be burned there, I don't have a blank disc or a drive. Is there another way?

Load Microsoft's Media Creation tool so that the Windows installation will play on the USB stick and start from the USB stick, you can then delete the hard drives and install a clean, new version of Windows.

If you have the appropriate program, drag the image onto a USB stick so that it is bootable. If the image is then on the stick (about 8GB, 4 Gb too small),

then boot from the stick as a test.

Otherwise only produce factory settings with external DVD LW and
Ubuntu, format the disk with gparted.

If important / sensitive data was also available on your notebook, you should first of all drag a bootable Linux distribution including a usable file eraser with overwrite function onto the stick before reinstalling Windows.

Otherwise, pure deletion, repartitioning and reformatting does not help reliably against later recovery attempts. A sensible overwrite tool covers the entire disk after repartitioning and formatting only in multiple passes of random strings, which later makes it impossible to restore parts of the old data records on the drive.

When this is done, you can restore the basic functions using a bootable Windows ISO (including drivers) from the manufacturer of your notebook. (i.e. Fresh Windows setup with device-specific drivers)

If you really shouldn't be able to recover data, definitely stick to Paroto92's answer.
