Create a Bootable Win7 USB Stick on OSX Prerequesites: • 4GB+ USB Stick • Windows 7 ISO from Microsoft downloaded to your OSX-Machine Preparing the drive • Open Disk utility • Find the drive, format it with the following options: • Choose Master Boot Record (MBR) • 1 Partition (full size) • MS DOS FAT Hacking Bootcamp If your Mac is rather new, you can't choose the 'Create USB' Option from Bootcamp so you have to hack Bootcamp first. • Open the 'Sytem Information' App and find out the 'Boot ROM Version' and your 'Model Identifier' • Open Terminal • Backup • sudo cp /Applications/Utilities/Boot Camp Assistant.app/Contents/Info.plist ~/Desktop/Info.plist.bak • Edit Info.plist `sudo vi /Applications/Utilities/Boot Camp Assistant.app/Contents/Info.plist' • Under DARequiredROMVersions add your Boot ROM Version, enclosed in tags, like you see it there. • Under PreUSBBootSupportedModel add your Model Identifier in the same manner. • Change PreUSBBootSupportedModels to USBBootSupportedModels, removing the 'Pre'. • Save+quit:wq • Sign the Boot Camp App again.
• This step does NOT work if you put the backup file inside the.app-Container, or added any other files. This is actually a mistake in most of the tutorials you find out there. • Install XCode • Install Xcode-command line tools • sudo codesign -fs - /Applications/Utilities/Boot Camp Assistant.app/Contents/MacOS/Boot Camp Assistant Creating the USB Drive • Open Boot Camp Assistant • Select 'Create USB Drive', uncheck the other options. • Select your preformatted drive and the ISO and you're good to go. Hello, I followed these instructions for my macbook 5,1 to make a bootable USB of windows 7.
The process is the same, regardless of the destination. Whatever media you use to create the bootable Mac OS installer on, it will be completely erased by the createinstallmedia command, so be careful. Whether you're going to use a flash drive, a hard drive, or an SSD, be sure to back up any data on the drive before you begin this process. Create a bootable flash drive for installing Windows. To install Windows 10 Education Edition from IUware, or if you have a Windows 8.x or 7 installation disk but do not have an optical (CD/DVD) drive on your computer, you can create a bootable flash drive for the installation.
I don't have my superdrive in my macbook so I'm trying to install windows 7 using bootcamp and the USB stick. I made a 100GB partition on my SSD to use for windows using bootcamp. When I restart and hold the alt key, my bootable USB for windows 7 never appears. (i formatted the USB with 1 partition in FAT and Master Boot Record before I used bootcamp to create the Windows bootable USB) What can I do? The USB won't boot to install windows. To add some tips onto this: • You can install Xcode command line tools WITHOUT Xcode, via the guide at (basically type xcode-select --install and click on Install (NOT on 'Get Xcode')). • If you are on High Sierra, you'll have trouble due to SIP (system integrity protection).
Just COPY /Applications/Utilities/Boot Camp Assistant.app to your DESKTOP, then edit the Info.plist of the COPY, and run the codesign on the COPY: sudo codesign -fs - ~/Desktop/Boot Camp Assistant.app/. Then launch the copy. • If your Info.plist does not have DARequiredROMVersions, ignore that part of the guide. On High Sierra, that stuff has been removed.
With the advances in technology, faster data access (SSD), and slimming hardware footprints, legacy technologies are typically the first cuts made to get these devices thinner and lighter while making them more powerful and efficient. Installing OS X has never really been a particularly difficult task, but try doing that on a MacBook Air or a system with a broken optical drive. Not so easy anymore is it? Even downloading the OS from the Mac App Store wouldn't do when the hard drive needs replacing or the Recovery Partition is corrupt. Luckily, Macs have a couple of options, specifically USB booting, and since most have an SD card slot, we can use those as well.
