A bootable USB drive is a handy tool if you need to reinstall OS X Yosemite on your Mac, or if you're updating other Macs. To create this drive, download the OS X Yosemite installer from the App store and then use a specific command in Terminal to load it onto the USB disk. How do I create a Mac bootable USB drive using Windows hi, i have not mac pc or laptop. I download el capitan.dmg or.raw and install it to usb stick with RMPrepUSB or transmac or coverted with dmg2img to iso and intalled to usb with rufus but failed.
Image via Before You Start The obvious first step here is to. But before you do anything else, a word of caution: once you've used the OS X installer, it will automatically delete the file you need to make the backup disk, so you'll want to either make a copy of the installer or create your disk before you upgrade.
You can use a USB flash drive, external hard drive, or DVD-R disc, but the USB drive is quicker. If you're using a USB drive, it has to be formatted as 'Mac OS Extended (Journaled)' and set to partition type 'GUID Partition Table' in order to work.
Image via Once inside, browse to the ' Contents SharedSupport' folder where there will be a file called ' InstallESD.dmg.' This is the image file that contains the information you need to create the backup disk. Step 2: Open Disk Utility (located in your Applications Utilities folder). Step 3: Drag and drop the ' InstallESD.dmg' into the list of drives on the left and select it.
This should make it appear in the Source box on the right. If not, you may have to click the ' Restore' tab as seen below.

Hi, First of all cant be write in a 8gb pendrive so i tried with 32gb and its worked.
But in bios bootmenu the efi partition of usb doesn't recognise. After so many search and try i just rename the efi partition to bootloader and its worked and at the end of installation its failed showing 'an error occurred while running scripts from the package 'clover uefi.pkg'. So next time i unselected the bootloader uefi.pkg (btw its shows zero kb there) and that time installation successfully finished. Now after boot nothing help to boot hdd without the usb. Tried copied efi folder, install latest clover nothing help.
