Before you can wipe securely your PC's hard drive, you'll need to burn a program called "DBAN" onto a blank DVD or place it on a USB drive.  You can ensure that your computer's disc drive is capable of burning by looking for the "DVD" logo on or near the disc tray. If your disc drive can't burn DVDs, you can use an external (USB) disc drive that's capable of burning DVDs. Go to https://dban.org/ and click Download DBAN in the top-right corner of the window. This will prompt the DBAN image file—also known as an ISO—to download onto your computer. Depending on your browser's settings, you may have to confirm the download or select a save location before the file will actually download. . Once DBAN finishes downloading, you can use your computer's "This PC" program to burn the DBAN ISO onto your DVD.  Make sure that the DBAN DVD remains in your computer when the burning process is complete. If you're using a USB drive, you'll instead place the DBAN ISO file on the USB drive and keep the drive inserted into your computer. Open Start, click Power, and click Restart in the pop-up menu. Immediately after clicking Restart, begin repeatedly pressing your computer's BIOS key. This is usually Del or one of the "F" keys (e.g., F2), but you can confirm the key that you're supposed to press by checking your computer's documentation online. If you miss your opportunity to access the BIOS, restart your computer and try again. On most computers, you'll use the arrow keys to select the "Advanced" or "Boot" tab to do this. Some BIOS models have the boot order options on the initial page on which you arrive. It should be labeled "CD Drive" or "Disk Drive" (or something similar). Again, use the arrow keys to select the appropriate option. With the "CD Drive" (or similar) option selected, press the + key until the selected option is at the top of the boot list. If this doesn't work, check the key legend on the right side (or bottom) of the screen to see which key you should press to move the selected option. For most BIOS pages, you'll press a key to do this; check the on-screen key legend to see which key you need to press. On some computers, you'll have to press another key to confirm the changes when prompted. Once the DBAN interface pops up, press the J or K key to move the selection up or down, then press Space once your computer's hard drive is selected.  Check the key legend at the bottom of the DBAN screen to confirm the keys that you use to navigate and select. If you have multiple hard drives (or partitions) that you want to erase, select them as well. Press F10 (or the key listed in the legend) to do so. Your hard drive will begin erasing. This process will take several hours at least, so make sure that your computer is plugged into a reliable power source. When you see an ad for Blancco on your screen, you can eject the DBAN DVD, at which point your hard drive has been securely wiped. If you want to reinstall an operating system on your computer, you can replace the DBAN DVD with your preferred operating system's installation DVD and then follow the on-screen steps. You may have to restart your computer to prompt the installation to begin.
