\begin{enumerate}
|
|
\item Type \textbf{o} to erase all former partitions
|
|
\item Type \textbf{p} to list all existing partitions
|
|
\item Type \textbf{n}, then \textbf{p} to create the boot partition. Press
|
|
\textbf{RETURN} to accept the first sector, then \textbf{+100M} for the
|
|
last sector
|
|
\item Type \textbf{t}, then \textbf{c} to set the partition type to FAT32
|
|
\item Type \textbf{n}, then \textbf{p} to create the root partition. Press
