Leo was confused. âThen why do people say âformat from BIOSâ?â
Within seconds, the drive was wiped cleanâno viruses, no corrupted files, no old problems. how to format a hard drive from bios
âBecause,â Maya explained, âthey really mean: boot from a USB drive to run a formatting tool before the main operating system loads. You need the BIOS to change the boot order so the computer starts from your USB stick, not the corrupted hard drive.â Leo was confused
The computer now launched the Windows/Linux installer from the USB. Leo chose âRepair your computerâ or âInstall nowâ and then âCustom: Install Windows only (advanced).â There, he saw a list of drives and partitions. He selected his main hard drive, clicked Format , and confirmed. You need the BIOS to change the boot
Maya helped him download a free tool called âRufusâ (for Windows) or âBalenaEtcherâ (for Mac/Linux). They used it to put a Windows or Linux installer onto an 8GB+ USB stick. This USB becomes a mini repair kit.
With the drive freshly formatted, Leo installed Windows/Linux from the same USB. It was like moving into a brand-new house. The Moral of the Story You donât format from the BIOS. You use the BIOS to point the computer to a formatting tool on a USB drive. Leo learned the difference the easy wayâby asking first. He saved himself from a common mistake: going into BIOS, changing random settings, and accidentally disabling his hard drive entirely.
He set the USB drive as the first boot device. Then he saved changes (usually F10) and exited. The computer restarted.
