Bootcamp thread for yi_D with Yosemite issues

Please do not post your serial number on a public forum.

You need to erase the NTFS partition (not remove it) and format it as FAT32. Clean the MBR, otherwise the installation will not work.Then use the Bootcamp Assistant created USB with W7 ISO and BC drivers to install it on this FAT32 partition.

1. You can convert the volume to FAT32 - diskutil eraseVolume FAT32 BOOTCAMP disk0s3

2. Use GPT Fdisk (http://sourceforge.net/projects/gptfdisk/) and put GPT 2,3,4 in the Hybrid MBR.

3. Install Windows on GPT 3.

Steps for recreating Hybrid MBR. Your 'p' output will look different than in this example. In your case GPT3 is the equivalent of GPT4 in the example, use defaults as suggested by Gdisk.

sudo gdisk /dev/disk0

WARNING! Hybrid MBRs are flaky and dangerous! If you decide not to use one,

just hit the Enter key at the below prompt and your MBR partition table will

be untouched.

Type from one to three GPT partition numbers, separated by spaces, to be

added to the hybrid MBR, in sequence: 2 3 4

Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): y

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

PARTITIONS!!

Do you want to proceed? (Y/N): y

OK; writing new GUID partition table (GPT) to /dev/disk0.

Warning: Devices opened with shared lock will not have their

partition table automatically reloaded!

Warning: The kernel may continue to use old or deleted partitions.

You should reboot or remove the drive.

The operation has completed successfully.

Now Reboot and verify the output of fdisk again.

Can you start Gdisk using

This is Gdisk

type gdisk

gdisk is /usr/sbin/gdisk

To start Gdisk

sudo gdisk /dev/disk0

If you downloaded the package and ran the installer, it should be in /usr/sbin/gdisk.

ls -l /usr/sbin/gdisk

If it does not show up try the following command

sudo find / -name gdisk -print -exec ls -l {} \;

Since you have two MS Data partition, DATA can be 07, but GPT#3 should be 0B. Once you install windows on GPT#3, The Installer should mark it as bootable in the MBR.

This entry should be a '0B' not a '03'.
