Thanks for your input.
Actually, I wanted to know the purpose of
this "new" free partition that was created
after the dual Linux installation.
When I just had Windows only, I did not
have this "free" partition at all. Besides,
this partition's size is only about 8MB.
What I meant by "safely deleting" this
partition was to ask if I could utilize this
partition by merging it to either the root
or swap partition if this is possible.
At any rate, I appreciate your feedback.
