Make a bootable USB

Hello!
So, I want to make a bootable USB drive of my OS X 10.8 after they take it out of Mac App Store... (soon we'll be having OS X 10.9, right?).
Anyway, I have a software required to make a bootable drive; I have an 8 GB drive prepared... but my question is:
I have OS X 10.8.5 installed. If I make a bootable drive... which 'version' of OS X 10.8 will be installed on it? The frist version (let's call it 10.8) or the version I have (onde again 10.8.5)? To be honest I prefer to have an 'original' version on the USB drive...
Thanks for any information you may give me!!
All the best!!

You cannot do this from your already installed system. You must get a copy of the actual Mountain Lion installer application.
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/
    Lion application. After Mountain/Lion downloads DO NOT click on the Install button.
    Go to your Applications folder and make a copy of the Mountain/Lion installer. Move
    the copy into your Downloads folder. Now you can click on the Install button. You
    must do this because the installer deletes itself automatically when it finishes
    installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
a. Open Disk Utility in your Utilities folder.
b. After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left
      side list. Click on the Partition tab in the DU main window.
c. Under the Volume Scheme heading set the number of partitions from the drop down menu to one.
      Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on the Partition button and wait until
      the process has completed.
d. Select the volume you just created (this is the sub-entry under the drive entry) from the left side
      list. Click on the Erase tab in the DU main window.
e. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the
      button for Zero Data and click on OK to return to the Erase window.
f. Click on the Erase button. The format process can take up to an hour depending upon the flash
     drive size.
3. Use Lion DiskMaker 2.0 to put your installer clone onto the USB flash drive.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.

This is not difficult and you will not have to download from the app store.
your computer has what is called a recovery partition that came with it.
simply hold cmd+R while you boot up. let go a second after you hear the chime.
you will boot into the recovery partition.
Use disk utlity to format your usb drive and then exit Disk utlity and go to Reinstall Mountain Lion.
it will ask you which disk you want to install ML onto. Choose your new USB drive.
easy peasy

My iMac came with mountain Lion preinstalled. I wish to make a Bootable USB Disk. I find that I am not allowed to d/load Mountain Lion from the App Store. I wish to make a purchase. Why can't I?

All he needs is the recovery disc assistant. It's a free download.

Make a Bootable USB Drive

My MacBool's hard disk crashed recently, so i had to get a new one. Unfortunately I lost my installation CD and dont even have any back up so now i have an ISO and DMG file for Mac os X Snow Leopard. Please tell me how to make a bootable USB for my mac WHILE USING WINDOWS 8.
Thanks

If you don't have the original OS X installation disk, then it depends on what these ISO and DMG files are. If they're a true, complete copy of the original installation disk made properly, then you can use Disk Utility to restore that image to a USB drive which should then work. If those image files are updaters only, then they will not be able to create a bootable installer.

Download installation files from app store to make a bootable USB

Hi,
I just got a new mac mini with OS X Server 10.8.2. I want to replace the original hard drive with an SSD, but I have problems downloading installation files from app store to make a bootable USB stick.
When i click the Purchases button it tells me that OS X Server is already installed, and I'm not able to download the files.
I have tried all the diffrent forms of Option key clicks but nothing works.
Anyone out there who have a solution?
Is it possible to get the installation media in some other way?
By the way. Is it possible to install the non server version on a computer thats bought with the server version pre installed.
I thought so. But I read something about firmware problems on a forum page?

You cannot download Mountain Lion or Mountain Lion Server from the App Store if it was pre-installed on the computer.
You can call Contacting Apple for support and service - this includes international calling numbers. They may be willing to arrange a download for you. Or you can reinstall via Internet Recovery: OS X (Lion/Mountain Lion)- About OS X Recovery.
No, you can purchase and download Mountain Lion from the App Store on the computer you want to install it if it now has Snow Leopard or Lion running.

should i make that bootable media ?) i have bought the windows from dreamspark ,, so i use a official iso and serial key

Hi,
This is not license problem, in my opinion, it's more relate with hardware and their driver problem.
Firstly, it would be better to contact the manufacture to identify if your computer support Windows 8.1 X64 edition.
Secondly, if your former system was not removed, try to access into the system and upgrade BIOS editon, after that, try to reinstall the system again for test.

Bootcamp cant make a bootable usb drive.

Hey guys,
When i try to make a bootable disk (USB) in bootcamp, it says he cant make it a bootable usb drive.
What to do?
Please come help.
Thanks!

GIavelotto.
Make sure you download the instructions to load windows7 using bootcamp. I found that if you repeat the steps in the bootcamp assistant, you will find that it will work.
First have you managed to set up a USB install disc based on step 1. Second put the windows support software onto your hard drive or another USB stick. You need to copy the windows support software across to the USB install disc you made in step 1. Make sure you create a separate folder for the windows support folder.
Then you can proceed to step 3 to create a partition for Windows. I set it to 50% which created a 230 GB partition for Windows and 230GB partition for my Mac OS. You need to create a partition at least 100 GB for WIndows to have enough space for the software. You may want to increase this to 150GB to create enough storage for data and images.
I found that you had to make sure that you were successful in each of the steps to create a windows partition before moving to the next step. What mac notebook are you using?

Can i make a bootable usb drive for os x yosemite on a windows pc?

I have a Macbook Pro 13" 2009 that I've installed a new hard drive in. How do I make an OS X Yosemite bootable USB drive (I have a 16 GB available)? I'm traveling, so all I have with me is a Windows 8 laptop. I have an iMac at home, so I expect I'll be able to do it easily there, but I have time now... Thanks.

No. You need a Mac for that.

How to make a bootable usb image backup, how to make a bootable usb image backup

I would like to make a bootable backup on my usb external flash drive (32GB). Is it possible? I don't have an OS x 10.7 installation disk.

A bootable backup of what? On a flash drive you could:
Clone an OS X installer DVD to use for installing OS X on other Macs.
Install a basic OS X system that might be used for emergency situations.
If your MBA system uses less than 32 GBs you could clone it to the flash drive.

HT203909 Why can't you provide specific instructions here about how to make the USB drive bootable? The article referenced is not dedicated to Bootcamp--too long, too many options. How do you make it bootable?

Why can't you provide specific instructions here in HT203909 (Boot Camp: Creating an ISO image from a Windows installation DVD) about how to make the USB drive bootable? The article referenced for partitioning the drive is not dedicated to Bootcamp--too long, too many options. How do you make it bootable?

If your BC Assistant shows the option to create a USB Installer, it automatically is marked as bootable. There is no need to have manual intervention to make a bootable USB. Once the process is manually modified, it is supported by the person modifying it.
You have two or three options (depending on your Mac Model).
1. Create USB... - Use a USB2 flash drive, which is erased and formatted. If your Mac supports ISOs then BCA will prompt for the Media. Any Mac which does not have a built-in Optical drive will support an ISO. There are specific Mac models which support both, DVD and USB based installation.
2. Download Software from Apple servers...
3. Install Windows...
Are any additional instructions really necessary?

How can I make a Bootable OSX USB Drive

Looking for instructions on how to make a bootable OSX USB thumb drive?
My mid 2009 MacBook Pro has a bad Hard Drive and I am going to start over with a new one. I keep getting an error message attempting to install on the current hard drive. In order to make it easier I would like to make a bootable USB Thumb drive get a new hard drive and start from scratch.
ALSO - any hard drive recomendations would be greatly apprecieated. (vendor and MFG)
Thanks

Arthur-
thanks, I never use WD. I used to work in computers and the WD drive was the most failed drive we would see. I only ask because I guess at some point I did not build the current drive correctly causing damage. I am starting to think about a new computer due to the optical drive now being dead as well.
My only concern about a SSD is the transfer rate. From what I have looked at the current config for a mid 2009 MBP will not get the max speed out of a SSD due to the wire rating in the machine. Any thoughts on a normal disk HD?
Thanks

Is it possible to make a BIOS usb key for a PC on a MAC?

I am not sure where to ask this question but If I needed to make a BIOS flash drive for a PC computer such as an HP Laptop or Desktop, would it be possible to do on the MacBook Pro running OS X Mountain Lion? I ask this because I thought I was going to need to make a BIOS flash update for an HP system and I did not want to use a CD to do it. I had downloaded the flash drive tool from HP which under a windows system would make a USB flash drive. I tried running the tool under Windows 7 on both a VM session and a boot camp session but both times I would get a message saying something similar to "You don't have permission" even though I was doing it as an admin. Turns out I didn't need it anyway but for future references can I even make a bootable usb key for a PC on a Mac?

Thank you for the info. I found the problem that I had under the Windows 7 on Mac was the extractor(hpusbf.exe) was not running under the Admin mode so it wasn't given permission to modify the usb File system. I think the other issue is that I was trying this on a 8GB flash drive and it kept telling me the partition was too large. I found the switch to use 2048 blocks and it created a bootable flash drive. The problem I have now is when I tried it on my old HP laptop, it boots up saying "FreeDos Fat" and stops. So I don't know what is going on but I think I am going to stick to making bootable CDs I just have to get some Re-writable CDs so I don't waste the CDs.
I tried your solution on the mac side and tried copying the dos files over but the drive would not boot. I think the problem is that the command.com file is not set as a system file. I am not sure how you can set command.com as a system file for windows under the MAC operating system. I know in windows you use attrib +S filename.

OS X Mavericks installer on bootable USB boots with stop symbol

I've recently been trying to reinstall OS X Mavericks on my late 2010 Macbook Pro but I've ran into some problems.
I followed this guide to create a bootable USB to reinstall Mavericks. So first of all the copying took longer than it's meant to, which at first was a bit concering but I just continued. Then, once it had finished, I boot up from startup by holding 'alt' and selecting the drive. It boots up like it usally does, but then after around a minute it came up with a stop symbol and a spinner below. I've left it to load but nothing happens, I've rebooted and even tried to copy the files again.
It's not like this method dosen't work because I did it when Mavericks first came out and it worked without a hitch.
Any help would be appreciated very much. Thanks.
