Bootable USB Drive

It seems that no matter where I go on the internets to learn how to make a usb drive bootable all i get is how to make a recovery drive for mac.
I DONT NEED a Recovery drive for mac. I just want to know how to make a USB drive bootable, not bootable with mac installation or windows installation, just how to make it bootable in general.
If it has to be bootable with something, i need boot camp to make it bootable. I am trying to install windows 7 on to my iMac (mid 2010, 21.5 inch), it will carry through to the restart into windows but windows will say "No Bootable Device -- Insert Install Disk and Press Any Key" but i have not messed up anywhere, it is all created correctly but boot camp refuses to make the drive bootable, i looked at the drive in disk utility and it says "Bootable: No" how do i get boot camp make the drive bootable, or can somebody tell me the exact steps to install windows 7 on mac with boot camp because it seems i am getting conflicting instructions.
Thanks.

The Bootcamp info.plist has the following entries. Notice that the 8,x models pre-date USB boot support in general. I have a 2010 server and I will test and see what happens.

How do I Install Windows 7 on Mac Book Pro via a Bootable USB Drive

Hi Guys,
I have a Mac Book Pro 13 inch, Early 2011 Processor 2.3 GHz Intel Core i5 (I initially had OS 10.5.8 which I upgraded to OSX 10.9.4 a few months ago).
When purchased it, I installed Windows via Super Drive (that being the only time i ever used the super drive). My Windows got corrupted for some reason 2 months ago. Hence, I removed the windows via Bootcamp to perform a fresh install. I discovered my Super Drive was no longer working.
Thereon I have been trying to install Windows via a bootable USB Drive but am failing to do so. After going through several forums, I have reached the following stage.
1. Created Bootable Windows USB Drive using Windows USB (http://www.wikihow.com/Create-a-Bootable-Windows-7-or-Vista-USB-Drive). Have used this USB drive to install windows on a DELL Computer
2. Bootcamp wasnt creating a partition for windows since no Windows Installation disc was being detected in super drive. (Solved it by downloading Toast Titanium and loading the .iso file on a virtual drive).
3. Boot menu was initially not detecting external drive, so installed rEFIt - An EFI Boot Menu and Toolkit. Now it is detecting the USB Drive.
Now when I boot from this device, it get a black screen with the message "No bootable device - Insert Boot Disk"
Request someone to please help me install windows as some softwares which I work with are windows based.

So my understanding is that my Boot Camp Assistant (BCA), since it does not allow USB installer, it sets NVRAM to boot from Optical Drive. Right?
Yes.
So can I change it or update it to another BCA version which supports the same??
All BCA versions drive the logic based on the Mac Model Identifier. Unfortunately there is no real workaround. .

Creating a Mavericks USB boot drive after the horse has bolted. Can I create a bootable USB drive from my iMac after installing Mavericks without saving the Install OS X Mavericks.app file? Do I need to re- download the whole 5.29 Gb again?

Creating a Mavericks USB boot drive after the horse has bolted. Can I create a bootable USB drive from my iMac after installing Mavericks without saving the Install OS X Mavericks.app file? Do I need to re- download the whole 5.29 Gb from the App Store again? My problem is my 4Gb/month allowance on a 12 month contract. I cannot purchase a data block from my ISP and although my speed is theoretically slowed to 64k after reaching my 4Gb, it actually ceases to download in reality.

HI tasclix, it depends what you mean by an OS X boot drive.
If you want a recovery disk from which you can reinstall (by re-downloading) or recover from a time machine backup, then nbar is correct.
If, however, you want to boot and run the OS X installer from the USB drive (so that you don't need to download again), then you will need a copy of "Install OS X Mavericks.app"; see this article:
http://support.apple.com/kb/HT5856
Before downloading again, search your system to see if the installer is still there - it's usually in the /Applications folder unless it has been deleted, but check your whole system for it anyway, you never know, you might still have it somewhere.

I am confused by the installation step that requires you to create a bootable USB drive for windows installation. What is the ISO image and why has it selected my Passport backup drive as the destination disc?

In the bootcamp installation it asks me to create a bootable USB drive for Windows Installation. To do so, I must choose an ISO image. What is that? When I click "choose" I don't understand the options presented. Is this the destination of the partition or where Windows will reside on the Mac? Why does it also indicate the the destination disk si my WD Passport Back up drive?

OK, so I have an apple superdrive hooked up to my mini (along with my Passport back up drive). I also have the discs for both 64bit and 32bit Windows along with the product key. I am still not sure what to do when faced with the options after "choose".

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.

BootCamp Assistant Error : Your bootable USB drive could not be created. "An error occurred while formatting the disk."

I have a Windows 7 Ultimate .iso file saved onto a "Mac OS Extended (Journal)" formatted USB flash drive. I am trying to install it with BootCamp Assistant and I keep getting the error message : Your bootable USB drive could not be created. "An error occurred while formatting the disk."
I have previously installed Windows 7 on my Mac (and it worked flawlessly - same .iso file), but I uninstalled it because I didn't partition enough space on my hard drive. I have used several flash drive to try and install and none have worked.
Some help would be greatly appreciated.

"Your bootable USB drive could not be created" "Boot Camp only supports 64-bit Windows installation on this platform. Please use an ISO file for 64-bit Windows installation."

I try to install windows7 system on my macbook air, which version is 10.8.5. When I open the bootcamp, it let me to choose a windows ISO image, which I've already downloaded from this website: http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325 /, it also asked me to select a USB drive, which is kingston that has 8GB. Then when I clicked "continue", it said that "Your bootable USB drive could not be created" "Boot Camp only supports 64-bit Windows installation on this platform. Please use an ISO file for 64-bit Windows installation." But actually the ISO image I downloaded is 64-bit windows7. I don't know why this would happen. Could someone help me please!!

Thanks for your feedbakc Kiranjj!
I identified the reason to be that the W8 installation file didn't download completely from a Mac OS-device. I downloaded from another Win-device and the moved the installation file with a USB-stick and then everything worked diectly! But thanks anyway.

BE-3000 Bootable USB Drive

I would like to make a bootable USB Drive and burn the 8.6.2.20000-etc upgrade ISO to it.
I was wondering is there any technical reason why a BE-3000 would not boot from a USB drive?
Will it only boot from a DVD drive?
As always thanks for any help

Hello, TNSeaBee.
Thank you for visiting Apple Support Communities.
I understand that you need to install Boot Camp on your system to access your .mil information. Here are some steps that will help you with that process. Make sure that the USB drive is in the correct format.
How do I download and install the latest Boot Camp Support Software?
If you're using OS X v10.8.3 or later, you can use Boot Camp Assistant to download the software. The Boot Camp system requirements page also links to the appropriate download page for Boot Camp Support Software. Follow the installation instructions on the download page.
To install Windows and the Boot Camp Support Software, you need a flash drive or other USB media, which must be formatted for the FAT file system:
Open Disk Utility, which is in the Utilities folder of your Applications folder.
Select the USB disk that you want to format. Remember that formatting the disk also causes it to be erased.
Click the Erase tab at the top of the window, then choose from the Format pop-up menu:
If the disk is 32 GB or smaller, choose MS-DOS (FAT).
If the disk is larger than 32 GB, choose ExFAT.
Type a name for the disk. The maximum length is 11 characters.
Click the Erase button, then click Erase again.

S205 - Steps to create a bootable USB drive using One Key Recovery (OKR) for backup image.

Hi Guys,
I just got my new S205. I am wondering how to backup the Windows OS including all factory settings to a bootable USB drive using One Key Recovery (OKR) 7.0. Basically I am afriad one day, my harddrive is failed or if I want to replace harddrive, I can reimage the harddrive back to factory setting and its OS (win 7). Would you share with me on the steps to do so?
I opened the OKR software and click on "Create Recovery Disk" -> "Factory Default Setting Disk" and Next, I couldn't see my USB drive? any one knows why?
thanks in advance.
New S205 owner.

I was able to do this, but it required reconfiguration of the HDD in my S205 (320 GB hard drive).
I used the built-in Windows Disk Management tool to shrink the size of my C: drive to 56,320 MB. [To accomplish this, I had to disable hibernation, and disable the swap file on the C: drive; and then re-enabled both after the process was complete.] 56,320 MB is more than enough space for the OS and all of the programs that I have installed (including the Professional version of Microsoft Office).
I then increased the size of the D: drive to 233,614 MB.
You can use different drive sizes, of course, but the D: drive must be of adequate size for the backup image.
Once the HDD is reconfigured, you can use One Key Recovery to backup your C: drive to your D: drive. From there, it can be copied to a USB (or copied across the network, etc. ... I've done both). Yes, it is 2 steps, but it's really easy.

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!

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?

Create a bootable USB drive from an ISO

Hi everyone,
I want to create a bootable USB drive from e.g. a Linux ISO. On Windows, there are tools like UNetBootin (http://unetbootin.sourceforge.net/) for that. Is there s.th. similar on Mac?
Thanks in advance

Hi. The easiest way to do what you want to do is to scan it for restore, and then use the restore from disk image tool to write it to an external disk. All of this can be done with disk utility.
First you will want to drag the ISO image into the Disk Utility sidebar. Then you select the disk image (in disk utility) and click the Convert button in the top toolbar. I recommend using the "read only" image format and you'll have to add the extension .dmg to the file. When the conversion is done, the new image will appear in the sidebar. Select that image and then go to the Images menu and select Scan For Restore. You may be prompted for your administrator password. When the scan is done, connect your external disk. Then select the volume in Disk Utility (the thing with the name of your disk, not the model number), go to the Restore tab and drag the volume into the Destination field. Now you can drag the DMG disk image into the Source field and click Restore. You may want to check Erase Destination.
That should do it, good luck!

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.

I'm on an earlier version of DU, but highlight the ISO or open it in DU & highlight it, click on the Restore tab, darag the ISO to the Source Box, & the USB drive to the Destination box.
Occasionally you have to rename the .iso to .dmg for it to work.

Mac Pro not Detecting Bootable USB Drive to Install Snow Leopard 10.6

Hi
I have to Mac Pro 2 x 2.8 GHz Intel Xeon. I have been running Leopard on them. I wish to install snow leopard, so i took out my USB HDD where I have made a Bootable Partition with snow leopard. I have used this in the past on all my machines to install snow leopard. Now when I try to install Snow Leopard from this on my mac pro, it does not detect in the "Option Boot" start up menu, it only shows my leopard disk. If I got to start up disk in system preference, then it shows my Snow Leopard disk, but when i select that as start up, it still boots to my Leopard..
Since I am doing a fresh Install , I have another HDD installed, formatted for snow leopard. When I launch snow leopard installer from Leopard and select install in the new drive, it does some installation , but when restarting it goes to my leopard again.
This is the case on both the Mac Pro;s, but not on my laptops, I tried on my air and my macbook pro, and my friends mac book pro, it instantly boots up to the usb drive with snow leopard.
So is there anything im missing ? Or is there something wrong with my Mac Pro's?
I dont have the snow leopard DVD, else I would have tried that too..
Please advice asap!!
Thanks
Sa1

Hey
Thanks for the reply!
I have two USB HDD, with the copy from snow leopard dvd, and both are formatted in GUID, they work fine on my laptops and even the old mac mini, just not working on two identical Mac Pros.. Its very strange, as it keeps booting to leopard, and if I remove leopard Disk, and just put the new one and connect the USB dive, its shows a folder with a "?" mark sign!
And the USB just works fine after its booted to leopard, it even starts installing snow leopard to the disk i assign, but it does not complete the installation as it boots to main leopard drive..
I have tried to reset PRAM on both machine, I have changed usb slot..
I dont know what to do!

How do I create a bootable USB Drive to install Windows 7 on a MBP Retina

I'm trying to install Windows 7 on a MBP Retina.(I'm running Mountain Lion) I followed BootCamp's directions to create a bootable copy of Windows on a USB Flash Drive. When I go to install, Boot Camp creates the partition, but I get a Windows black screen that says that "there is no bootable drive - hit any key". I have to force shut down, because hitting any key does nothing. I tried the Bootcamp directions at least 3 times, but have been unable to get the USB Drive to start up the Install program. Any help would be greatly appreciated.
Thanks
Joe

Disconnect all external drives. Only have the the USB flash drive connected.
