Bootable Mac Os El Capitan Usb

As has been the case for the last few releases of OS X, the easiest method to make a USB install drive is with the free program, Diskmaker X. It’s been updated today to support El Capitan. Step-by-Step instructions on How to Create a Bootable MAC OS X El Capitan USB Flash Drive.Copy and Paste Code: http://goo.gl/j9Fz6b. From this point, we've now provided plenty of installation files whether for installing macOS on Windows or on Mac. Such as macOS Sierra DMG, macOS High.

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

Mac Os Bootable Usb Iso

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'

Bootable Mac Os El Capitan Usb

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.....?
