Created a bootable USB with El Capitan installer

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

Program Startup Disk not recognized USB. If I press option after power on its not boot too 🙁 I used El Capitan 11.6 image and Transcend USB 3.0. Faiz Orz October 14, 2016 at 10:07 PM. Try to boot with the USB Installer and before that apply this recommended settings.

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

I have the same issue with my USB bootable stick created with TransMac utility. I have no other mac os near me, so can't use mac software. So my Air 2009 couldn't see this USB stick with el capitan - tried to unplug it due to load with no success. Tried with 5 different sticks - USB stick is not a problem here. Any solution guys? Step 2: Now that El Capitan is downloaded, you will now need to create a bootable OS X El Capitan USB flash drive. Doing this will allow you to install a fresh copy of OS X on your Mac from the flash drive, rather than having to upgrade to the new OS over an existing installation.

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
