How to erase no disk drive laptop
I was told that I have to use a bootable CD to erase everything on the laptop, but I don't have disk driver in it, how can I perform a completely erase on the hard drive?
Try to use the USB instead, I think your computer has USB ports not type-c ports right? Or if you want to keep the operating system and sell the laptop, you can try to erase free space after you deleted things you don't want to keep rather than the entire disk. I'll make step by step guide in this page.
Create bootable USB to erase hard disk
Prepare a blank USB, 1 GB is OK, ByebyeData Eraser ISO file will not require much of the storage and download the latest version of this program and install it. And download a third party USB burning tool Rufus before you run the data sanitation program, OK, let's check on the detail steps:
1. Run ByebyeData Eraser and click Bootable media.
2. Eraser will guide you how to create the ISO file and just follow the wizard to the final step.
3. Now you can see the ISO file is stored to the default path and you can run Rufus now.
4. In Rufus interface, select the USB you just plugged in, blank or not, Rufus will format it first and choose the ISO file to burn. This small tool is easy to use and burning really fast.
5. Close all the running programs and restart the laptop.
6. Press some key to boot from USB; the message may vary according to different computer.
7. Click Erase disk and select the main disk in the disk list, you can see there're 14 kinds of erasing standards in the security column, specify one to continue, simple and advanced overwrite methods are good enough to secure personal data, 1 pass overwrite methods in ByebyeData Eraser will stop data recovery software from getting you data back, more passes plans will take more time to perform, by the way.

Besides, if you have already deleted files and folders or uninstalled programs in control panel, you have better option than creating a bootable USB to wipe the entire disk. In ByebyeData Eraser you can simply use the Erase free space function to clean each partition or the hard drive, which may save effort on creating bootable media and rebooting.
