Hi I have a newish MBA approx 1 year old that was running mountain lion. I think i have deleted the entire system and any partitions it boots and says no bootable drive when i try cont R it starts internet recovery but just sits there

Hi during playing around with my MBA i think i have despite all the warnings deleted everything from my laptop. I do not have a back up or usb start up. when i boot the laptop it says no bootable device found, i have tried various configerations of alt cntr r etc the best i can get it to is a spinning grey globe that says looking for internet connection. it does not see my wifi so i do have a usb-rj45 adapter that if i plug into the R/H side usb port lets it see the internet (i think) it then brings up a down load bar but this never moves and in the end brings an error nummber up i think it was -0007 or -0002.
Do i have to buy new mountain lion or usb start up stick
I have access to a windows PC (not mac) so can use this to create a usb if someone helps an idiot out
thanks Martin

I had just finished backing everything up and was about to hit the wipe button when I found a solution that worked for me: here: https://discussions.apple.com/thread/4144252?tstart=0
It gdisk to be installed, and a bit of terminal knowledge, but it fixed the problem for me. For this step:
add partion 5 to the MBR
It was partition 4 for me. You should first use gdisk's 'p' command to find the number of your bootcamp partition, and then use that number.
