Under Mojave-0 the first FAT File System should be our EFI partition. As my screenshots come from within a Parallels VM, the device names are different than what will be displayed on a Hackintosh. The way you establish the boot files in a new ESP partition (or on C: drive in item 3 above) is with the BCDBOOT command. Next use the command devtree -b to look for the location of the EFI partition on the main macOS drive. GPT also stores cyclic redundancy check (CRC) values to check that its data is intact - if the data is corrupted, GPT can notice the problem and attempt to recover the damaged data from another location on the disk. In most cases, booting from your C: drive will only work if the drive is MBR partitioned, the C: drive partition is marked as active, and the computer is booting with a legacy BIOS, or UEFI in CSM mode. In contrast, GPT stores multiple copies of this data across the disk, so it’s much more robust and can recover if the data is corrupted.

That should give Windows 10 plenty of room to create a recovery partition. If this data is overwritten or corrupted, you’re in trouble. You can try using MiniTool partition wizard to shrink your main partition, leave 600 mb free in front of it. The fix there is to mount the partition and delete the fonts folder which gives you a little more room. The reference I believe is for a win 10 system with a GPT partition so an EFI system partition is being referenced. On an MBR disk, the partitioning and boot data is stored in one place. Microsoft does have a support page on this situation and I am trying to find the correct one. GPT allows for a nearly unlimited amount of partitions, and the limit here will be your operating system - Windows allows up to 128 partitions on a GPT drive, and you don’t have to create an extended partition. Drives can be much, much larger and size limits will depend on the operating system and its file systems.
It’s called GUID Partition Table because every partition on your drive has a “globally unique identifier,” or GUID - a random string so long that every GPT partition on earth likely has its own unique identifier. It’s associated with UEFI - UEFI replaces the clunky old BIOS with something more modern, and GPT replaces the clunky old MBR partitioning system with something more modern.

A small, under 1MB partition with code EF02 The EFI partition with. The partitions would be most likely in this order. While in the live DVD Ubuntu session try to get gdisk installed via apt-get, and list the partitions with sudo gdisk -l /dev/sda. It’s a new standard that’s gradually replacing MBR. Since your desktop came with Windows 8 preinstalled I believe you already have an EFI partition.

Otherwise it becomes a cumbersome trial-and error process, which involves manual manipulation of the partitions. I suppose this is the normal situation, the procedure should handle these cases automatically. This is a silly little hack and shouldn’t be necessary. ValidateLayout: Too many MBR partitions found, no room to create EFI system partition. MBR also only supports up to four primary partitions - if you want more, you have to make one of your primary partitions an “extended partition” and create logical partitions inside it. MBR works with disks up to 2 TB in size, but it can’t handle disks with more than 2 TB of space.
