my first post

I'm trying to install PCLinuxOS to a Dell Optiplex 755, with no joy,
it always fails after finding the usb when it's looking for the loop
Searching for the loop image:
/dev/sda1
/dev/sda2
/dev/sda3
/dev/sda5
/dev/sda6
I've tried the following
DVD
USB
UNetboootin
all with the same results it acts like it's not seeing the HD yet it's copying from it..
system specs
Intel E4400 duo
4G PC1066
DVDRW Sata
500G Sata
this is a mini box system that doesn't allow you to change or move around drive jumpers, so any help I'd appreciate
thanks so much
Indian..
