You need to erase the Linux Ubuntu installation from the hard disk drive.
To erase everything on your Ubuntu system, simply run "sudo rm -rf /". If needed, add --no-preserve-root for extra safety. For mechanical drives, you might need to physically shake them while power is on, but be aware this will destroy the drive.
To format a drive, such as wiping it, you can use the dd command. It’s recommended to run this from a live disk to avoid file lock problems on your current Ubuntu system. If you’re using sda, sdb, or another partition, replace the drive label accordingly. You can also feed random data with /dev/urandom if you prefer. Only rewrite the first 64 MB to make the partition appear empty to the OS.
