Question

bootcamp doesn't open windows installer after restart

Hi guys,

I am trying to install Windows 10 on my Macbook Retina (early 2015), OS El Capitan 10.11.4. After mounting the ISO on a good USB drive (a Kingston 64GB USB Type C) and partitioning the hard drive with BootCamp, my mac doesn't load the Windows installer - it starts normally as a Mac OS.

I have already looked for similar questions around and tried (without success) to:

- Format the USB-C drive on FAT mode

- Reset SMC and NVRAM

Would you please help me in this? I am quite lost and would need to install Windows urgently!

Thanks in advance!

MacBook (Retina, 12-inch, Early 2015), OS X El Capitan (10.11.4)

I had to restore a disk to a single partition in bootcamp assistant and repeat the installation process.

After that installation went smoothly.

Were you prompted for a USB by Bootcamp Assistant? Please see https://help.apple.com/bootcamp/assistant/6.0/ as a reference. Your 2015 Macs should not need a USB, because they use an internal partition called OSXRESERVED.

The Windows ISO must be on your Mac. They are usually 3-4GB, larger ISOs are mixed-mode ISOs and do not work with BC Assistant.

If you use Windows Media Creation to tool to create a USB, it is not an ISO file, but the full installer with individual files.

I have the same problem. I do exactly what is written on: https://help.apple.com/bootcamp/assistant/6.0/#/bcmp173b3bf2

In "prepare your mac" section. After Step 5 there is a restart and OS X starts again without windows installer.

my bootcamp doesn't even show install with USB option. Its MacBook Pro (Retina, 15-inch, Mid 2015).

Disconnect all external storage, and run SMC and NVRAM reset. Once complete, retry the installation. If you get a partitioning error, check if you have an OSXRESERVED partition.
