Q: How can larger 111 GB partition to create a Windows installation in bootcamp ?

Did you replace the 1TB HDD with 1TB SSD in a 1TB fusion drive iMac 2013?

Can you post the output of

diskutil list

diskutil cs list

It seems to be a CS issue.

Your CS volume is built incorrectly. The SSD (121GB) part should be at index 0 in the CS, and the HDD should be at index 1. Can you backup OS X to Time Machine and post back when you have a backup? We need to rebuild the CS correctly. Your current layout is also going to give you very bad performance, because blocks are being moved from a slower disk to a faster disk for retrieval later.

BC Assistant uses the disks at index 1 or higher to shrink by default. There is no way to create a partition larger that the size of the disk at index 1.

I did it again the following commands:

"sudo diskutil create cs [ ArbitraryName ] disk0 disk1s2 ,

This command must use the 121GB SSD first, not the 1TB HDD. You will need to boot into Internet Recovery and I can provide detailed steps. Can you backup you important files, even if you do not have a Time Machine backup?

Please use Yosemite to rebuild the CS.

Please see Re: Issue trying to clean install Windows 10 on Fusion Drive. el Capitan. as an example.

Hey Loner T, I posted a problem I am having but I am not sure if I posted it in a public forum. I See how helpful you are to everyone on here and I even put your name in the title of the post haha. I am going to post my problem in this reply I hope that is ok. I am new to these forums so please forgive me if posting in here is wrong. I am desperate!

Hello. I Have been using Windows 7 with Bootcamp on my Macbook Pro Late 2013 15 inch Retina 16GB 2.6GHz Core i7 since I bought the computer brand new. I turned on my mac the other day and out of nowhere, the Windows Partition was gone. The only thing that I did do differently was that I turned on FileVault and encrypted my system. I am wondering if it affected my partition because of that? I am not sure. I am nervous, though because I have all of my really important work files on the partition and I haven't been able to access them at all.

Everything I tried to do so far:

I tried plugging my MBP into my iMac and booting it in target disk mode and I couldn't find any files from the Windows partition. For some odd reason the bootcamp partition is greyed out in Disk Utilities and it is now called "disk0s4."

I have a Windows 7 disk that I was able to boot from and it was about to install Windows but I was afraid that it was going to overwrite everything so I canceled it.

When I boot my MBP now and hold alt, like I used to always have to do to get into Windows, it shows 2 "Macintosh HDs" whereas it used to show one "Macintosh HD" one "Recovery Drive" and one "Windows" drive. (I am guessing that by encrypting the drive it may have messed up the naming of the voumes... Not sure)

I have turned off FileVault, unlocked, and decrypted the system to see if it would help but no luck.

I tried hitting verify disk and then repair disk and nothing worked.

I also tried to hit mount disk and that did nothing.

Is there any way I can access the files on the partition if there is no possible way to install windows 7 again without overwriting everything?

To anyone who helps answer this, thank you in advance. I am so stuck!!!

I have been reading the forums and I saw that "Loner T" asked someone to type in these commands in terminal:

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

Check my terminal results below: I also attached the text file of the terminal session.

Here is the link to my original post if you want to answer it there instead of here. Thank you so much. If you do answer it there, I will come back and delete it off of this thread.

Can I suggest that you start a new discussion on Boot Camp and post your details? Please use Find answers and ask new questions as a method of starting a new discussion. Based on your GPT, you will most likely need
