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
Therefore, you can create bootable USB for your Mac using Transmac on windows 10/7/8/8.1 here you will learn the easiest method of creating bootable USB. As you know that Mac OS EL Capitan is the newest version among Mac. In here just follow my steps to create a bootable USB installer for your Mac. Is the twelfth major of the Mac operating system. Finally, I could boot up the Mac while holding 'option/alt' and my USB drive appeared as a bootable device! 17 minutes later I can startup OSX! I may go ahead and re-download the installer and create a new bootable USB using 'createinstallmedia', just in case there was a problem with the image I used, but at least now I can boot up the computer!
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'
Below are the steps needed to create an USB flash drive El Capitan bootable installer. Download the InstallMacOSX.dmg file by clicking on the OS X El Capitan 10.11 link in the Apple document 'How to get old versions of macOS'. These instructions assume this file has been downloaded to your /Downloads folder. Apr 27, 2021 Download: OS X El Capitan This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. Mar 01, 2016 This step-by-step procedure will teach you how to create a bootable USB drive installer for Mac OS X El Capitan.This method will also work for the other iterations of OS X (including the Yosemite, Mavericks, and Mountain Lion updates).
Bootable Usb Windows 10
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

It was 2009 when Apple last released a new operating system on physical media. Things have proceeded remarkably smoothly since version 10.7 switched to download-only installers, but there are still good reasons to want an old, reliable USB stick. For instance, if you find yourself doing multiple installs, a USB drive may be faster than multiple downloads (especially if you use a USB 3.0 drive). Or maybe you need a recovery disk for older Macs that don't support the Internet Recovery feature. Whatever the reason, you're in luck, because it's not hard to make one.
As with last year, there are two ways to get it done. There's the super easy way with the graphical user interface and the only slightly less easy way that requires some light Terminal use. Here's what you need to get started.
- A Mac that you have administrator access to, duh. We've created El Capitan USB stick from both Yosemite and El Capitan, but your experience with other versions may vary.
- An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive. For newer Macs, use a USB 3.0 drive—it makes things significantly faster.
- The OS X 10.11 El Capitan installer from the Mac App Store in your Applications folder. The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
- If you want a GUI, you need the latest version of Diskmaker X app. Version 5 is the one with official El Capitan support.
- Diskmaker X is free to download, but the creator accepts donations if you want to support his efforts.
The easy way
Once you've obtained all of the necessary materials, connect the USB drive to your Mac and run the Diskmaker X app. The app will offer to make installers for OS X 10.9, 10.10, and 10.11, and it should run on OS X versions all the way back to 10.7—support for 10.6 was dropped in the most recent release.

Diskmaker X has actually been around since the days of OS X 10.7 (it was previously known as Lion Diskmaker), and it's still the easiest GUI-based way to go without intimidating newbies. If you're comfortable with the command line, it's still possible to create a disk manually using a Terminal command, which we'll cover momentarily.
Bootable Os X El Capitan
Select OS X 10.11 in Diskmaker X, and the app should automatically find the copy you've downloaded to your Applications folder. It will then ask you where you want to copy the files—click 'An 8GB USB thumb drive' if you have a single drive to use or 'Another kind of disk' to use a partition on a larger drive or some other kind of external drive. Choose your disk (or partition) from the list that appears, verify that you'd like to have the disk (or partition) erased, and then wait for the files to copy over. The process is outlined in screenshots above.
The only slightly less-easy way
If you don't want to use Diskmaker X, Apple has actually included a terminal command that can create an install disk for you. Assuming that you have the OS X El Capitan installer in your Applications folder and you have a Mac OS X Extended (Journaled)-formatted USB drive named 'Untitled' mounted on the system, you can create an El Capitan install drive by typing the following command into the Terminal.
sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X El Capitan.app --nointeraction
The command will erase the disk and copy the install files over. Give it some time, and your volume will soon be loaded up with not just the OS X installer but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection.
Whichever method you use, you should be able to boot from your new USB drive either by changing the default Startup Disk in System Preferences or by holding down the Option key at boot and selecting the drive. Once booted, you'll be able to install or upgrade El Capitan as you normally would.
