Thanks fir the replies.
got a pro disc from dell!
As did I. That allows me to reinstall the OS.
it would be handy to be able to restore it to factory settings before disposal
That's why I used the Dell backup software to save the factory setting to a thumb drive.
Not concerned about the space; it's just annoying that sometimes it grabs a drive letter randomly and I have to go into disk management to fix.
Sounds like I really don't need this partition.
