Could you not see any drives?  Or that you there wasn't space to
install on that drive?

Upgrading to CentOS7 from CentOS6 isn't as sumple as 'yum upgrade
CentOS 7.0-1406'.  You need to follow the instructions here:

Why CentOS 6.4?  6.6 is the latest release.  There are a bunch of
security holes in 6.4's installation media.

Look in /etc/sysconfig/clock to tell the system that your clock is
UTC.  The GUI tool 'system-config-date' (in a package with the same
name) is a graphical tool for setting date/timezone settings.
