In Topic: The dreaded boot0 error, with a twist

11 May 2013 - 02:47 PM

To wipe the entire disk clean you can type dd if=/dev/zero of=/dev/sdx but this will take a very long time, and is not necessary.

Instead, wipe just the first MB of each partition like so: dd if=/dev/zero of=/dev/sdx1 count=2048 (repeat for sdx2 ... etc).

Then use gdisk to wipe all traces of the GPT and MBR: gdisk -Z /dev/sdx (Run this command twice.)

Now your disk is clean, unformatted, and un-partitioned so you can install any OS you want.
