perfSONAR User Q&A and Other Discussion

[Andrew Brennan <>]

I burned a DVD with the FullInstall ISO, booted that and then chose both 
the options for using the entire USB disk (ended up with the GRUB prompt 
when I rebooted later from the USB disk).  Then tried formatting the USB
disk with fdisk so that I'd have a pre-existing bootable Linux partition 
for FullInstall to install into -- also ended up at the GRUB prompt when 
rebooting later.

Guessing that either it doesn't like my partitions or the GRUB config is 
munged, but I haven't put too much work into it yet as this was supposed 
to be something that filled in the spare moments of other projects.  :)
