My disc won't boot - Prohibited sign

1. If you just put the installer on the USB flash drive, it won't boot. I made one with DiskMaker X (formerly Lion DiskMaker)
2. The failure of your carbon copy cloner clone is more puzzling.
3. I would download the Mavericks installer again and make an installer flash drive with DiskMaker X, and use that to wipe the MBPR drive and do the clean install.
4. Another option, if the MBPR won't boot, would be to try to Boot into your recovery partition (hold down ⌘R at restart until you see the Apple symbol), go to Disk Utility, and repair your hard drive. While you're there, repair permissions too. OSX Tips Using the Recovery HD
5. there are some other options too, but those are what I'd try first.

1. definitely a puzzle.
2. you might still try DiskMaker X, maybe it will work where the other one didn't.
3. Try to boot into single user mode and repair your hard drive: Repair Your Hard Disk in Single User Mode | Everything Macintosh
4. You could download Recovery Disk Assistant, which you can use to repair your hard drive or reinstall OSX: OS X: About Recovery Disk Assistant
5. You could try mounting the MBPR HD in target disk mode on your other mac, and then repairing the HD. How to use and troubleshoot FireWire target disk mode
6. If the MBPR has an internet connection, it should be able to use internet recovery OS X: About OS X Recovery

Eric,

The answer is actually a lot simpler. The OSX version that you can download from the App store has a PlatformSupport plist file from 8/24/13 which does not include the latest Retina MacBook Pro string and will therefore not allow you to boot it.

The file that comes with the preinstalled Mavericks version is dated 9/17/2013 and does include the latest hardware strings. Just copy it into System/Library/Coreservices and your problem is fixed.

Eric,

That's one way to do it. Another would have been to just add the "MacBookPro11,1" string. If you still have the recovery partition, you could also have reinstalled Mavericks over the net, which will include the right plist file.

I'm glad I was able to help.

I'm having a similar problem...

Model Name: MacBook Pro

Model Identifier: MacBookPro6,2

Processor Name: Intel Core i5

Processor Speed: 2.53 GHz

Number Of Processors: 1

Total Number Of Cores: 2

L2 Cache (per core): 256 KB

L3 Cache: 3 MB

Memory: 8 GB

Processor Interconnect Speed: 4.8 GT/s

Boot ROM Version: MBP61.0057.B0C

SMC Version (system): 1.58f17

OS X 10.6.8

I am trying to install Win 7 on my MBP w/ Parallels. I copied a Windows 7 iso from Microsoft's site to install via USB/CD. The first time I held down the Option key after the chime plays, it did not work. I tried again. It worked but only had the option to boot from HD. I burned the ISO to another USB.

Tried again, it worked. I now had 3 options to boot from. Main HD, USB 1 and USB 2. I tried USB 1 and eventually ended up in a DOS-like environment. All black with "No bootup disk was found, insert and press any key" something to that effect. Below that line, the exact same message. The rest of the screen was all black but the same message at the top. I tried to do so but it wouldn't respond at all to key strokes. I restarted, tried again.

From this point on, I could not get back to that screen. The next 10-12 attempts all failed, in a row. It would just start up normally. I then tried a CD with the ISO burned on and holding C to boot from CD drive, 0/3. I find it hard to believe the first 2/3 attempts worked but the following 12-15 all failed IN A ROW. I'm holding down the key as soon as I hear the chime and letting go until I see the desired effects just the same way I did the first 2-3 attempts when it worked. Any help would be greatly appreciated, thank you in advance.

At this point I don't know what else to do

I too am having problems like this. A "client" had installed Windoze via BootCamp, but then used Disk Utility from OSX to create an extra partition of 32GB.

Resulting in that the MBP couldn't do anything but boot in Windows !!

No matter how I attack the HDD I end up with either "folder with questionmark" on boot, and "prohibited" when trying to boot on a USB-OSX-stick.

Can boot on Linux-disk, but not install.

Can re-partition the disk, but to no avail.

Have tried TestDisk from Germany (http://www.cgsecurity.org/wiki/TestDisk) but no effect.

And from this string: Can not boot on RecoveryDiskAssistant: prohibited

SO - should I purchase DiskWarrior (which I know they have at my local Apple-dealer), or should I return the machine under warranty (it is only 2 weeks old)

i too am having problems, and I've noticed that the maker of DiskMaker has tweeted that DiskMaker won't work on the new MBP retina's. Not sure what the workaround might be. I tried removing PlatformSupport.plist as noted above, but that didn't work... still see the circle-with-line-through-it sign when I try to boot from the USB drive. I have no trouble booting from that drive on an older Macbook Air.

Got it: Boot woth Cmd+Alt+R and recover via the Internet. Worked for me - pheww ;-)

that's a good workaround to know about, though it's still frustrating that 10.9 on a macbook pro retina cannot boot from a USB drive. Is this intentional or a bug?

same problem

I have os maverick downloaded from store - version - download date 17 dec - version 9.1

this bootable disk start anywere beside my new MacBookPro retina 15'' late 2013
