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.
My MBA 2012 with OS X 10.9.4 Mavericks won't boot anymore - it simply freezes after the initial jingle. I already tried resetting NVRAM and SMC, but to no avail. I don't have any time machine backups. However, I still have a disc image of Mavericks sitting on an external hard drive, a USB stick and access to a notebook with Windows 7. I haven't yet found any tutorial on how to create a bootable USB drive on Windows in order to reinstall OS X on my beloved Macbook Air. Any help would be greatly appreciated! According to the first answer here,, there's a tool with a free trial called TransMac that can do it.

Just make sure the USB drive is formatted with GPT and not MBR. What might be easier, however, is that that model has support for Internet Recovery. If you boot holding Command-R and you have a WiFi connection, it can actually boot into recovery mode without a recovery partition on a drive (or even without a working drive).
Having said that, your description of a crash right after the boot chime could signify a more serious hardware problem and you may not be able to boot anything. If you boot holding the option key down, the startup disk selection screen should appear. If it crashes anyways, you may be looking at a hardware problem. I know this question is old but it is still valid. I was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac. Using Michael D. Dryden's, I was able to use the Diskpart command to clean and prep a GPT partition on a flash drive for an OSX Mavericks install image.
