Can Apple computers partition after installing win10?

The partition format is:

The C and D drives are in NTFS format. macos

The X partition is OS

x Extended Journal.

The disk partition table is in GUID format (no hassle of updating the system and Quick Startup).

Next, let's talk about boot

Explanation of cmap and the principle of Apple EFI partitioning. Literally, boot

cmap stands for boot and camp, which means boot center, and it must be stored somewhere on the hard disk of our computer.

OSX as well as Recovery

HD, which belongs to Microsoft Windows. Unexpectedly, such a partition composition is also the reason why Mac devices are not capable of multi-partitioning Windows in 2015.

Because in 2015, Mac devices no longer support MBR startup, so Windows is installed in the traditional MBR mode

In the case of 10, the microSFT directory cannot be written in the EFI folder, resulting in no boot entry in the EFI, so that Windows cannot be started

10 systems. And before 2015, even if the MAC device is not written into the MICOSOFT directory in the EFI partition, it can still be booted with the MBR boot file of the local disk, the friend said, abandoning the old thing is Apple's consistent concept, from the first generation of IMAC comes with *** optical drive, you can see how bold Apple is. Since the GPT disk partition table is higher than the MBR disk partition table in terms of performance and data reliability, there is no reason why Apple should not abandon the latter.

In a sense, MBR+GPT hybrid boot is Windows

XP because it only supports MBR boot, Windows

The 7 8 also supports MBR boot, so we were able to install a multi-partition operating system on devices prior to 2015.

However, starting in 2015, Mac no longer supports single-item MBR boot systems (Windows

XP), so the MBR boot method was abandoned, and the pure GPT disk boot was used instead, that is, the Mac device in 2015 had one less instruction to search for the full BCD file, and would only read the boot BCD file of the EFI disk.

First, first of all, open the Apple computer, enter the win10 system, find "this computer" on the computer desktop, right-click on the slag click, select "Manage" in the right-click menu, and click to open.

2. Then, select "Disk Management" on the left side of the "Computer Management" interface and click to open.

3. Then, in the window, you can see the current Apple computer win10 disk usage.

Fourth, finally, select "Unused Disk" below to change the partition of Apple's computer win10 system, and solve the problem.
