Okay I'm trying to create a BOOTABLE Windows7 image on a USB key from a Mac running Lion. My image is .iso format. I tried:
And this succeeded in writing the files, except in DISK UTILITY on the mac, it shows the partition type as GUID Partition Table and not 'Master Boor Record'. Booting the key on my Vista computer yields the error 'No boot sector on USB Device'
From what I can tell, bs=1m in the DD command should have left 1 Megabyte for the boot sector, but for some reason this area of the USB Key is not set up correctly so that it will boot
How can I fix this, or correctly use dd to write a bootable cd image such that it is now a bootable usb drive?
Note: in the instructions I read about, they recommended renaming my Win7.iso to Win7.dmg before using DD, which made absolutely no sense to me, so I didn't do it. I could try with that step now, but it takes 1.99 hours to write the image to the USB drive so there is a huge penalty to trial and error here. Thank you.

Use Disk Utility Options to set the partition type to Master Boot Record before you do dd.

Centos Format Usb To Mbr Windows 7
I had a similar problem when trying to create a bootable USB disk from OSX. The issue was that UnetBootin doesn't set up the Master Boot Record correctly on the USB disk. You have to do this manually with Disk Util and fdisk.
- Format the disk in Disk Utility, with the correct MBR
- Open Disk Utilty
- Select the USB device
- Click Partition
- Select 1 partition in the partition layout
- Select “Master Boot Record” in the options
- Select MS-DOS (FAT) in the format type.
- Click Apply, then Partition
- Close Disk Utility
This will wipe the USB disk and set it up with the correct boot record
- Install the MBR binary from the SysLinux project
- Use the command line diskutil to find the device name for your USB drive.
- Unmount the USB drive with the command line. NB: Be sure to swap the device reference (in my case it is /dev/SOMEdisk2) with the correct one for your usb key that you identified in the previous step – this will change for each machine.
- Mark the partition active, then unmount it again
- Download Syslinux and extract the mbr.bin file
- Install the MBR NB: see my full instructions if you need further help with steps 4 & 5.
- Use UnetBootin to install your OS install files
- Download and install UnetBootin if you haven’t already
- Load the application, choose your preferred distribution, and then click OK
- When it’s finished, eject the USB key and use it

Format a USB key with a Master Boot Record (MBR)
- in Terminal: diskutil list
- note the name of your USB key (mine was /dev/disk1)
- in Terminal: diskutil eraseDisk MS-DOS 'WINDOWS10' MBR /dev/disk1
- replace /dev/disk1 with the name of your USB key
Mount a Windows 10 disk image
- in Disk Utility: select File › Open Disk Image › select your .iso
- in the left pane: click on the newly mounted image
- in the right pane: select the name and copy it: something likeCCSA_X64FRE_FR-FR_DV5
Copy the disk image to the WINDOWS10 USB key
- in Terminal: cd /Volumes
- in Terminal: cp -R CCSA_X64FRE_FR-FR_DV5/ WINDOWS10
- replace the image name in the example with the name of your disk image
- the slash at the end (after DV5 in the example) is important
- it took more than 90 minutes to copy to a USB 2.0 usb key with, no progress indicator

This method doesn't use dd nor have I tested it.
You should be able to use UNetBootIn to transfer the filesystem in the ISO to a USB drive. UNetBootIn is an open-source, cross-platform utility for transfering bootable CD/DVD images to USB drives.
Run UNetBootIn (runs on Windows, Mac OS X and Linux) and select the

radio button. Then choose ISO
from the dropdown menu (ISO is the default) and put the path to the ISO file into the path field. From there select the desired USB drive to transfer it to and click OK.6,83333 gold badges2525 silver badges4242 bronze badges

Have you ever needed to make a bootable USB stick drive? We will actually be doing this as part of our live events in order to be able to upgrade a Windows XP machine to Windows 7. We will make the USB drive bootable and add resources from the Microsoft Deployment Toolkit such as Operation System, applications, drivers etc. The result will be a thumb/stick USB drive that we can not only wipe the Window XP, but will install Windows 7 and a suite of necessary applications and drivers AND, most importantly, still have all the user's data!!!!

In the meantime, here are the simple steps to take a blank USD thumb drive and prepare it:
- Open an elevated Command prompt.
- DiskPart.exe is a text-mode command interpreter that enables you to manage objects (disks, partitions, or volumes) by using scripts or direct input from a command prompt.Before you can use DiskPart.exe commands on a disk, partition, or volume, you must first list and then select the object to give it focus. When an object has focus, any DiskPart.exe commands that you type act on that object.
- Type List disk to find the disk number of the USB drive.Displays a list of disks and information about them, such as their size, amount of available free space, whether the disk is a basic or dynamic disk, and whether the disk uses the master boot record (MBR) or GUID partition table (GPT) partition style. The disk marked with an asterisk (*) has focus.
- Selects the specified disk and shifts the focus to it. You only need to type the first three letters of the command so for select disk simply typing sel dis will work.
- Type CLEANSpecifies each and every bytesector on the disk is set to zero. This will completely delete all data contained on the disk. On master boot record (MBR) disks, only the MBR partitioning information and hidden sector information are overwritten. On GUID partition table (GPT) disks, the GPT partitioning information, including the Protective MBR, is overwritten. If the ALL parameter is not used, the first 1MB and the last 1MB of the disk are zeroed. This erases any disk formatting that had been previously applied to the disk. The disk's state after cleaning the disk is 'UNINITIALIZED'.
- Create Partition Primary or cre par pri, creates a Primary Partition (there's a surprise J). Other options available are EFI, EXTENDED, LOGICAL, MSR.
- Type ACTIVE to mark partition as activeACTIVE writes a value to the disk which is read by the basic input/output system (BIOS) at boot. This value specifies that the partition is a valid system partition. A partition must be selected for this operation to succeed.Romance of the Three Kingdoms XI Download Features.

so i just brought a 128GB sandisk ultra usb 3.0 because as a computer tec im tired of fumbling through my tons of usb drivers to do a job. , i want my windows installers & Linux, bookable tools and such all in one usb. so i looked into multibooting usbs and came across many tools, one being SARDU. but i need a hybird UEFI/MBR boot and my laptop doesn't support uefi & legacy simultaneously only one or the other. so using SARDU i cant see or boot from the usb unless i switch bios to legacy mode, works well because i see and can boot from all of what i have windows installers and linux distros but i have to keep switching back and forth between legacy and uefi. i was wondering if i can make the usb primarily Uefi bootable BUT also bootable for a old MBR if needed.
Hi, I have a bootable Windows 10 USB flash drive that was created using Rufus so it has GPT partition table for UEFI setup. I want to put it back to MBR partition style using Diskpart.
In diskpart if I select the disk and then use the clean command does the disk go back to MBR by default? By that I mean when I type create partition primary will the MBR partition style be used automatically? I wondered if it might just create another GPT partition on the flash drive because that was the last partition style that was on the USB flash drive?
