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.

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'

Capitan

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.

The next section can only be done on a mac that is capable of running El Capitan. This includes macs that have the potential to run El Capitan but have been upgraded to a newer OS. A mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit. When downloaded open to InstallMacOSX.pkg, double-click on. Mac OS X El Capitan ISO: Overview. The ISO Files for a software system are those that can be burned into a bootable DVD and then they can use the DVD to install the particular Software or Operating system on ones PC/Mac/MacBook. In this tutorial and video walkthrough, I’ll show you how to create a bootable USB drive for OS X El Capitan in just a few easy steps Note: your USB flash drive must be at least 8GB in size. Ensure that there’s nothing on the drive that you wish to keep, as this process will completely erase the drive including any volumes. After the copy of 'Packages', 'BaseSystem.chunklist', and 'BaseSystem.dmg' is complete, you should have a bootable USB drive that can install El Capitan on a Snow Leopard machine. Just restart and hold down Option as soon as the screen turns black and don't let go until the boot loader screen appears.

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.

Create a bootable OS X El Capitan USB Drive: Making a bootable OS X El Capitan USB Drive is easy and doesn’t take very long at all. There are a number of benefits to creating this type of boot drive, including the fact that it makes it very easy to install a fresh copy of the operating system you have configured on it.

Another benefit is that you will have a very easy time installing an operating system on a completely separate partition or on a virtual machine. By creating a boot disk you will have fast access to a portable installation whenever you need it.

Bootable
  1. You will want to start off by connecting your flash drive to your Mac
  2. Download and Install the latest version of DiskMakerX (or check here how to download and use DiskMaker X step by step)
  3. Run DiskMakerX and click “Yosemite (10.10)“, as there is currently no other version available for El Capitan.
  4. Next you will want to select the install file and in the Applications folder select “Install OS X 10.11” and click “Choose”.
  5. Click “An 8 GB USB thumb drive” and select the flash drive you plugged into your Mac.
  6. Click “Erase” then create the disk.
  7. You will then need to click “Continue” and enter your administrator password when prompted.
  8. Once the process has finished, simply click “Quit”.

You will now have a working bootable OS X El Capitan USB drive to use whenever you want. You can choose to rename the drive to “El Capitan” as opposed to “Yosemite”. Because DiskMakerX does not yet have an option for El Capitan, it will automatically name is Yosemite.
