I have a 100Gb partition for QEMU purposes. However, I was installing Windows 10, but the installation failed and corrupted. Is there a way to completely wipe that partition so I can start over?
# lsblk -il | grep part sda1 8:1 0 512M 0 part /boot sda2 8:2 0 40G 0 part sda3 8:3 0 40G 0 part sda4 8:4 0 38.8G 0 part
If you partition would be 'sda4' then:
dd if=/dev/zero of=/dev/sda4 bs=1M count=10
would be enough.
