We are developing/customizing an application.Ĭonsequenty we periodically create a built environment and send it out for testing.Īs bug reports and change requests are actioned we cut new build images and send them out. I'm using virtual box 4.1.16 on Linux and creating linux client vm's. Or get the converttoraw to output a sparse file? Or use the partitions parameter and write out the raw image in a bootable form to USB?
MAKING A BOOTABLE MAC USB WITH VIRTUALBOX HOW TO
This works but it is VERY SLOW installing direct to USB.ĭoes any one know how to get raw disks larger than 7.3G without using the 'partitions' parameter?
Solutin 3) Use a vmdk to link the usb device '/dev/sdc' directly to the VM as storage. This takes time and greatly slows down the write to the usb.

Solution 2) If I use VDI's and convert them to raw it works but the convertoraw process writes them out full size not as sparse files. Solution 1) If I use the 'partitions' parameter V'box will see the large 'disk' but I can't boot the usb after writing it out. No matter how large I make the raw image file Virtual Box only sees the raw disk as 7.3GB and this is not large enough. The above method works but it has a problem. VBoxManage internalcommands createrawvmdk -filename /vmimages/Machines/loop1-imagefile.vmdk -rawdisk /dev/loop1Ĥ) Create the VM selecting the vmdk as the disk.Ħ) Write the raw image file to usb in sparse format: Losetup /dev/loop1 /vmimages/Raw-images/imagefile.rawģ) Create a raw vmdk defining the loopback device as a raw disk: Any advice or pointers would be gratefully appreciated.ĭd if=/dev/zero of=imagefile.raw bs=4096 seek=256x12000 count=0Ģ) link the raw image file to a loopback device: I've hunted round a number of sites and cherry picked what looks like an efficient solution. Type the convert GPT command and press Enter.Įnter the create partition primary command and press Enter to complete the process.I need to create bootable usbs from a VM on a regular basis. Type the select disk command with the number assigned for the USB flash drive (for example select disk 4) and press Enter. Type the diskpart command and press Enter.Įnter the list disk command to view all drives connected to your computer and press Enter.

However, this time, you should use the following steps to use the Diskpart command-line utility on Windows 10 to create the appropriate GPT partition, and then follow the above instructions.
In this case, you may need to redo the entire process again. If the USB flash drive is not working with TransMac, it could still be a partition problem. Create a GPT partition on a USB flash drive

Once you complete the steps, you can now insert the USB flash drive on your Mac computer to install, reinstall, or upgrade the operating system to the latest macOS version, which can be Sierra, Catalina, Big Sur, Monterey, or higher. TransMac creates a macOS USB bootable drive warning. Select dmg macOS file to create a bootable USB drive dmg file with the macOS installation files. Right-click the USB flash drive and select the Restore with Disk Image option from the left navigation pane.Ĭlick the Yes button to confirm the erase of the USB flash drive data.
MAKING A BOOTABLE MAC USB WITH VIRTUALBOX INSTALL
To create a bootable USB drive with macOS, use these steps:ĭownload and install TransMac on Windows 10.
However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) are not working when you need them the most, you can use a Windows computer to rescue your Apple device. This is one of the main reasons you should consider making a macOS bootable USB when your device works properly. If the unexpected happens with an Apple computer, you can use a macOS bootable USB with the installation media to repair it.
It’s just a matter of time until your computer will refuse to start, which could happen for many reasons, including (and not limited to) file corruption, hardware failure, and buggy update. It does not matter whether you use macOS, Windows 10, or Windows 11.
