I booted successfully! I'm now posting this from within my PCLOS-LXDE partition. Luckily it seems Unetbootin didn't overwrite anything besides vmlinuz. Then from Unetbootin, I uninstalled the Debian Frugal Install. Thanks for all your help Patrick013, Old-Polack, and Bald Brick!
Oh, by the way, do you guys have any recommendation on how to do either a LiveUSB or frugal install of Debian? I couldn't get a Unetbootin LiveUSB to work.(or,as shown by this thread, a Unetbootin frugal install )
Edit: Does PCLOS-LiveUSB work for other distros?
Presently PCLinuxOS-liveusb only accepts PCLOS ISOs or files.
If you have an ISO of Debian, then there MAY be another way to do a LiveUSB install.
It depends on the files present in the ISO, but should be worth trying.
Essentially it goes like this
isohybrid -partok debian.iso
If the ISO is not suitable you will get an error. If no error then the original ISO is amended so you may wish to work with a copy.
If all is OK then you can write the ISO to a Primary Partition of the USB stick using the 'dd' command
dd if=debian.iso of=/dev/sdXY
.... where X is the device number and Y is the partition number.
Use a primary partition slightly bigger than the ISO.
Mark it active or if using Grub then chainload the partition to boot it.
It might work for you ...... Debian is one I have not tested here .....
