Created a bootable USB with El Capitan installer

Follow these steps to create a bootable USB installer of El Capitan in Terminal. Connect the USB flash drive to your Mac. Give the flash drive an appropriate name. You can do this by double-clicking the device's name on the desktop and then typing a new name. Try rebooting your Mac and hold command-r at boot. That should put the machine in recovery mode, without needing another computer to fix it. The kernal panic really messed up both OS on my MacBook Pro. I can't run recovery mode or run the Mac in safe mode. I tried running the internet recovery mode but didn't work. Then Right-click on that flash you want to create bootable USB for Mac OS El Capitan then select Restore with Disk Image.

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

decided to use migration assistant, most apps not working plus all the clutter from pre clean install

decided to do another clean install but MBP won't boot from USB and uses the recovery version instead.

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
