Partition Problem can't remove Partitions (Tried Everything.)

So I've been trying to BootCamp my Windows 8.1 Pro x64.

But when i came to the install section where i choose and partition, and of course I choose the bootcamp partition.

But somehow it did not work, so i just restarted and went back to yosemite.

And I opened up my disk utility, and saw there was created different partitions,

like diks02s, disk03s and so on.


And when i press the minus button it won't get removed, and message comes up.


Partition failed with the error:

The requested size change for the target disk or a related disk is too small. Please try a different disk or partition, or make a larger change.


So il try to resize, some hundreds mb, which does not work, when il try to resize, it just won't it is preparing to resize for hours even thought we are talking about 200mb resize here, i waited and waited for like 6 hours and it did not resize.


So i thought to get to the boot area (Like when you restart and hold in Command + R) and resize from there, it worked! But for like an half hour, before the same message came up :


Partition failed with the error:

The requested size change for the target disk or a related disk is too small. Please try a different disk or partition, or make a larger change.


And yes I've been trying to resize from the boot area.


Nothing works!

1. You should not delete partitions created by Bootcamp via Disk Utility and vice-a-versa.

2. During your first Windows attempt, what was the error message?

3. Yosemite creates a CoreStorage logical volume group/logical volume containing your OS X volume (Mac OS X Extended). Disk Utility on Yosemite has bugs where manipulating such volumes can lead to errors.

4. Deleting disks and volumes in Local Recovery compounds the problem, and can render you Mac unbootable, and you can lose your data.


Can you post the output of the following Terminal commands?


diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0


The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

So what should i do now ?

The message that came up when i was booting that it could not find the partition that it was supposed to bootcamp and as stupid as I am, I did a partion for windows on the 200gb osx disk which was my Mac HD and I thought that my work and it did not. So i went through an format, and got all this diskes.

1. Do you have a backup of your OSX side?

2. Does Windows contain any data that you want to save?


Depending on these two answers, the easiest method is


1. Back up OSX using Time Machine - Mac Basics: Time Machine backs up your Mac - Apple Support.

2. Boot into Internet Recovery - OS X: About OS X Recovery - Apple Support.

3. Erase your internal drive and restore from the TM backup in Step 1 - OS X Yosemite: Recover your entire system.

4. Install Windows using BC Assistant - How to install Windows using Boot Camp - Apple Support.


Please be aware that TM does not backup Bootcamp partitions.

Did you erase the entire 256GB disk, or just the OSX partition during Restore? The Restore will not bring back the Microsoft partitions.


The other issue is that your Wininstall is on a 1TB disk. You should use a USB2 flash drive of 8+ GB, otherwise the Installer will consider both, the internal and the other external attached storage and fail. You should disconnect all external storage and only have the USB built by BCA and internal disk for Windows installation to work correctly.
