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.
Can't install OSX el capitan, stuck on installation screen Hello! Was trying to instal el capitan on my macbook, the installation starts and after a few minutes stops and a messaging saying the os x could'nt be install on the computer, please contact the software editor to get help. How to boot up from a USB bootable drive to install El Capitan onto a fresh hard drive on your Apple Mac. To see how to create an El Capitan USB boot disk, c.
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

Are you trying to make a bootable installer? Do you have the El Capitan installer downloaded from the App Store? You cannot make a bootable DVD but you can make a bootable flash drive.
Bootable USB Installers for OS X Mavericks, Yosemite, El Capitan, and Sierra
First, review this introductory article: Create a bootable installer for macOS. Second, see this How To outline for creating a bootable El Capitan installer. Simply replace the Terminal command with the one from the preceding article by copying it into the Terminal window. You will need an 8GB or larger USB flash drive that has been partitioned and formatted for use with OS X.
Drive Partition and Format
- Open Disk Utility in the Utilities' folder.
- After Disk Utility loads select the drive (out-dented entry with the mfg.'s ID and size) from the side list.
- Click on the Erase tab in the Disk Utility toolbar. Name the drive, 'MyVolume'. <---- IMPORTANT!
- In the drop down panel set the partition scheme to GUID. Set the Format type to Mac OS Extended (Journaled.)
- Click on the Apply button and wait for the Done button to activate. When it does click on it.
- Quit Disk Utility.
Create Installer
Open the Terminal in the Utilities' folder. Choose the appropriate command line (in red) depending upon what OS X installer you want. Paste that entire command line from below at the Terminal's prompt:
Command for macOS High Sierra:
sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install macOS High Sierra.app
Command for macOS Sierra:
sudo /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install macOS Sierra.app
Command for El Capitan:
sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X El Capitan.app
Command for Yosemite:
sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X Yosemite.app
Command for Mavericks:
sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X Mavericks.app
Install El Capitan From Usb Bootable Drive
Press RETURN. You will be asked for your admin password. It will not echo to the Terminal window. Then press RETURN again. Wait for the return of the Terminal prompt signifying the process has completed. It takes quite some time to finish. Be patient.
