Q: Loner T, Help? - Yet Another Bootcamp/Resizing/Win 10 Cluster

Loner T, you've helped many out - thanks from us all!  Perhaps you can help me? ......


Running El Capitan.


I made the mistake of resizing my Mid-2012 MacBook Air hard drive after installing Windows 10.  I have only 128GB on my MBA hard drive, and it appeared to me that the partition for Windows was only about 35GB and that Windows (and apps) was taking up most of that partition, so I wanted to increase the partition for Windows - but I ended up in post-partition **** like others.  Before I did this Windows 10 was running correctly (if that matters).


I am willing to try a clean install of Windows 10 since I only had a few apps (Office, mainly) and I didn't lose much.   I will be using an ISO of Windows 10 Pro I downloaded from Microsoft, which is on a USB drive connected to my MBA.


When I run Bootcamp it prompts me to make my MBA HD a single journaled drive, then it purports to allow me to create a Windows partition - which I do - then when I go to install Windows 10 I get to "Windows Setup" which asks "Where do you want to install Windows?"   I shows 4 items in a list, two of which look to me to be the OS X main boot drive (about 80GB) and supposed Windows partition (about 35 GB).  I select "4," the supposed Windows partition, I get a message "Windows cannot be installed to this hard disk space.  Windows must be installed to a partition formatted as NFTS."  So, I then use the "Format" command right there in "Windows Setup," and I get a message that says "We could not create a new partition or locate an existing one.  For more information, see the Setup log files."   (I can't find any Setup log files BTW.)


I'm stymied - any suggestions?

Loner T just wanted to let you know that because of that link you sent me I solved what appears to have been my particular problem with installing Windows 10 via Bootcamp - I just needed to remove the other "USB" drive (actually an SD card) I had attached, so that the only USB drive attached was the one with the Windows 10 ISO on it - seems to haev done the trick as I was able to get past the roadblocks I described above.   Many thanks for your help!

    Please see Boot Camp: "We couldn't create a new partition or locate an existing one" alert during Windows 8 install - Apple Support . This is valid for W10 as well.

     

    Based on where you are, you no longer have a W10 installation. Please post the output of the following OSX Terminal commands, if the previous method does not work.

     

    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.

    These are the instructions at that link:

     

    This can happen if any Thunderbolt or USB storage devices--other than the USB media that contains a Windows ISO installer--are connected to the computer during the install process.

    1. Shut down your computer.
    2. Disconnect all Thunderbolt and USB storage devices, except for the USB media which contains the Windows ISO installer.
    3. Try the installation again.

     

     

    I addition to the USB drive with the Windows 10 ISO I had an SD card installed - so I have removed it and I will try the install again.  If that doesn't work then I will run the terminal commands and post the outcome.
