Created a bootable USB with El Capitan installer

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.

Chris brown fame album. tried to get Maverick back and basically ended up with a non-working MBP that went into a boot loop

Mac Os X El Capitan Dmg Bootable Usb Download

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.

Mac Os Sierra

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
