Using a Windows USB drive on a Mac is possible with the right tools.
Hello. You have a Hackintosh running only Windows and want to install it alongside OS X using a USB drive. You need a tool similar to Rufus to create the bootable USB. I’m not referring to Boot Camp, as that could damage your bootloader. Are there any instructions or programs that make this process straightforward on macOS?
Just divide the desired drive for Windows, pull out the ISO file, and move the contents to the USB root. Start the USB and set up Windows on the chosen partition. The bootloader should identify Windows automatically.
During the installation of Windows, you'll need to format the same partition once more and then use it for setting up Windows.
I won't install Windows on another disk, but thank you for your assistance. Files copied successfully. Good luck!
Alright I am able to boot from the USB. However... I have a drive that I have split in 2 partitions. 1 for storage on OS X and 1 for Windows. Windows wont be installed to either becuase the partition table is a MBR..
Unix-like systems (OS X) come with "dd" pre-installed as a disk imaging utility. Launch the terminal and enter "lsblk". This will display information like this: $ lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTsda 8:0 0 111.8G 0 disk ├─sda1 8:1 0 104G 0 part /└─sda2 8:2 0 7.8G 0 part [SWAP]sdd 8:48 1 3.7G 0 disk └─sdd1 8:49 1 3.7G 0 part /media/brady/308C3D258C3CE74E This shows a USB drive of 3.7GB present at /dev/sdd, mounted on sda1 in your media folder. The exact path may differ depending on your setup. To use dd, type the command as: dd if=/path/to/your_disk of=/dev/sdX. This process may appear to freeze or not show progress until completion, which is normal. Be gentle, young learner.
You should have set up Windows initially, since doing so could corrupt iBoot and render OS X unusable. However, there’s a more straightforward method to generate a bootable USB in OS X. Begin by launching Disk Utility from Applications/Utilities. Navigate to your USB device within the left panel and format it using MSDOS(FAT). Within the "Options" section, select "GUID Partition Table." Next, access the folder containing your Windows ISO and drag it into Disk Utility. This will mount the ISO, enabling you to restore it onto the USB drive. Close any open applications. In Disk Utility’s "Restore" tab, move the Windows ISO from the left side into the "Source" area, then drag your USB drive into the "Destination" zone. Click "Apply"; you’ll be prompted for a password—enter it and confirm. The process may take roughly half an hour.
Afterward, you’ll need to format the hard drive where Windows will be installed. Converting MBR to GPT isn’t feasible in OS X; a Windows installation is required for that step. To prevent data loss, back up your files from the OS X storage partition to another drive before proceeding. If backup isn’t possible, you may require an additional HDD.
In Disk Utility, select the HDD designated for Windows and format it, creating two GUID Partition Table (GPT) partitions of your desired size. Go back to "Options," choose "GUID Partition Table," apply the changes, then exit Disk Utility and power off your PC. Unplug the HDD/SSD you’re using and boot from the USB drive. Follow the installer’s prompts, selecting one of the newly created partitions to install Windows. Once the installation completes, reinstall OS X by plugging in the original drive and using F12 to select it during boot. If this doesn’t work, you’ll likely need to restart the process from scratch, ensuring proper partitioning before installing OS X.
I plan to set up Windows on the SSD, clean the HDD, add Windows to the HDD, and then move OS X to the SSD. I think Cinemera (the bootloader for OS X) can still detect the Windows installation even if it was installed earlier.
Try my approach first, since all the steps you described are just complex ways to resolve issues. My method stays a bit detailed but is easier than multiple installations or reboots. All you need to do is transfer your files from your OS X storage partition to another drive during installation. Once that’s done, restore everything—about two hours at most. Your process involves backing up your OS X install data, the storage partition, then installing Windows, followed by moving Windows to a second drive, restoring the OS X files to a flash drive and reinstalling it, and finally recovering Kexts, bootloader, and other components. This should take roughly four to five hours. I’ve handled Hackintosh projects before; it’s rarely quick or simple, but handling reinstalls carefully makes things smoother. If Chimera recognizes new installs, you won’t need to manually select the boot drive with F12 when using Windows.
