You may wish to reformat some of your legacy Linux partitions and to erase any data they contain. To do so, please select those partitions as well.
Please note that you don't
have to reformat all pre-existing partitions. You must reformat the partitions
containing the operating system (such as /
,
/usr
and /var
) but not the partitions
containing data you wish to keep (typically,
/home
).
Please be careful when selecting partitions. After the formatting is completed, all data on the selected partitions is deleted and you won't be able to recover it.
