Unable to install F18 into an existing linux partitions.

[Dan Thurman]

I was not able to install F18 via LiveCD/Anaconda
as it appears to insist on (unformatted) free space.

I was able to install F17 with anaconda, which
allowed me to specify the /boot and / software
destination having two partitions wiped out by
newly reformatting them while installing.

In F18, one has a choice to choose LVM, BRFS(?), or
Partition schemes, so I choose the Partition
scheme, checked that I wanted no help, to
manually modify and/or define the software
destination and hovering the cursor over 2nd
button, the highlight says: "Please wait... software
metadata is being loaded" and nothing happens for
over 30 minutes of waiting.

I do not want to use the 'reclaim' button because
this might mess up the partition table and screw
the entire disk.

I also noted that while waiting, I was able to set
the locale, but not allowed to change the date,
time nor 12/24 hour selections, they are greyed out,
even though I was able to do this on the time/date
menubar but this has nothing to do with anaconda.

So, what can I do at this point?
