booted from it, erased my MBP (mid 2009), clean install from USB installer

Roblox player launcher exe install. tried to get Maverick back and basically ended up with a non-working MBP that went into a boot loop
did a reinstall from MAS, ended up DLing the entire Installer again, went to bed and in the morning and 'working'
MBP again, plus all the clutter and non working apps.
Made a new bootable USB key using terminal and yes it finished and yes it said bootable at the end as well as in Disk Utilities.
However when trying to boot from USB, start+Option, or start+cmd+r still no sign of the USB stick, which i guess would leave me
with a non clean install again.
Any help, suggestions...?
Cheers
