Make a USB stick bootable, this is not a casual task; but it is doable. The Boot the PC or Mac with a USB stick can also have many advantages - because you had one a long time ago DVD for booting the computer equipped, then it can meanwhile be scratched, lost in the collection, unusable due to environmental influences and wear and tear, or something else. A bootable USB stick is safer there - and if in doubt, it can simply be stuck to the back of the computer to find it again.
Very important, if you want to make a USB stick bootable, is the format in which the stick is partitioned. For example, if you want to boot an Apple computer from the USB stick, then bring yourself FAT: and NTFS nothing - although files can be exchanged between PC and Mac with it; but You can only boot Windows from FAT and NTFS systems. Do you want that Boot OS X from the USB stick, then must for partitioning Mac OS Extended chosen as the format .
OS X already provides the right tools for this, which is why the process should not take longer or even 5 minutes. First you go to the folder Program and there in Subroutines. You will find it there Disk Utility. Once you've found this, you can now connect the USB stick you want at the latest. Theoretically, a USB hard drive or another USB device is also possible. But they usually have too much space that you waste by not occupying them.
Im Your Mac's hard drive utility You will then see the available storage media in the left column; including your USB device. To make a partitioning, you select the stick from which you want to boot. Then you click on the options list above the right part of the window on the point Partitioning. The current settings of the stick will then be displayed.
Under the heading Partition layout you will find a roll menu in which you can select the desired number of partitions on the selected storage medium. For the bootable USB stick 1 would not be a bad choice. So choose 1, even if there are currently several partitions. But before we start partitioning we have to go to below again Options ... be clicked. In the window that appears you choose the GUID partition table out - this is the only way to make the USB stick bootable!
Now we come to the roll menu in which you can select the format. There you choose yours OS X Boot Stick for Mac OS Extended (Journaled). Almost done - now click on Apply (bottom right) and confirmed by clicking on Partition the process in the message window that appears. Partitioning is done. Now we can get started.
Let's take the current operating system as an example OS X 10.11 El Capitan. There is a rescue partition here, but make a USB stick bootable and having it as a backup for a new installation ensures a little more security if you don't have internet access. In addition a bootable USB device with installer is worth it as a Backup for the futureif with the coming in the fall MacOS Sierra that OS X will slowly but surely die out.
So let's start: The first thing you should do is Installer for OS X 10.11 El Capitan download - you can find it as a download in the Mac App Store. However, do not carry out the installation with the program - you probably already have the OS on the disk. Rather, look in the programs for the Installation app (DMG file). Small additional remark: to accommodate the installer on the bootable USB stick, it must have a capacity of at least 8 GB (the linked article brings you ideal USB sticks and models for the future).
So now it gets interesting; you have the formatted stick and the installer. Now you have to Port Endeavor program. There you enter the following command without additions or line breaks (the term "example" stands for the stick name. You can change this when partitioning):
sudo / Applications / Install \ OS \ X \ El \ Capitan.app/Contents/Resources/createinstallmedia –volume / Volumes /example –Applicationpath / Applications / Install \ OS \ X \ El \ Capitan.app
You confirm the code or its execution with the enter key. An admin password is then requested and entered by entering Y (as "Yes") you then confirm the desired process again. It can take a while; the Port but gives information about the current progress. If this is 100% complete, then he gives the term last Done File
The Start the Mac with a bootable USB device connected or equipped with the installer will be the same not automatically as a start volume chosen. Here you can help by looking for the corresponding start sound when the Mac starts up the Option or Alt key tried hard. In the following selection you can now control the stick.
Of course, there is also a third-party wizard for the whole procedure. Here you can Make a USB stick bootable with just a few clicks and see to it that a Mac is saved. The most widely used and recommended tool for this is DiskMaker X (Link leads to the page with information and download of the tool), which automatically carries out the steps described and only requires the OS, the stick and a few clicks from you.
If you Boot Windows 7, Windows 8 or Windows 10 via USB then you need either the original DVD or an ISO. The Windows operating system as ISO for download abound on the internet. In addition to the complete instructions for the USB stick with Windows boot, you should also take a look at the ISO reference at this point Chip.de are recommended, where you can also find ISO files for Windows 7 and Windows 8 versions.
If you are really lazy, you can also boot Windows 10 via USB; with an original Windows 10 USB stick, which you can order from Amazon, among others. Depending on the version, that costs up to 130 euros.
But if you want to save the money, proceed as follows when creating the Windows 10 USB stick:
Almost everything in digital home use overflows these days USB, so that should also be Boot from a USB stick to be possible. With both OS X and Windows, you can get helpers on USB relatively carefree. One Make the USB stick bootable, this is not rocket science, but a safe step towards the system start in the event of problems with the hard drive or other failures.
