Q: Windows will not boot

I'm panicking, I was in the final stages of prepping my old macbook and new macbook systems and ran chkdsk (not with the /B cause it complained since my system is NTFS) but I think it was right after that my bootcamp partition was not bootable (and its been many weeks since I did a backup and was just about to). It shows up in Disk Utility and hope its just a Master Boot Record or an easy fix, also can't view the bootcamp device or any files in Finder. Tried to delete the Recovery partition and EFI to get a MBR fix...I know enough to be dangerous.


Yosemite

Win 8.1

    Does the Winclone Restore fail with an error message? Was El Capitan ever on the 2015 Mac?

    Haven't tried, since the windows partition was gone for the couple days since you helped fix it. My  2010 time machine backup should be just about done (I'm without a 2015 backup in the meantime and did put some work into reducing head space, but wouldn't lose anything per se)

    Don't have the ethernet USB dongle so it would take overnight to transfer over wifi 100GB or so?

    As a test, backup Yosemite from the 2015 Mac on TM. Boot into Internet Recovery. Erase the internal disk on the 2015 and format it as an MBR disk (assuming it is 2.2TB or smaller). Restore Winclone and test Windows. If it works, we can convert the disk to GPT using Gdisk, and then repartition, test Windows, and restore the 2015 Yosemite from TM.

    Only have enough external disks/storage right now for one time machine backup (2010 currently) and a couple windows images etc on another drive. I can scrounge around and see If i have another drive for the 2015 180GB data on the MAC partition.

    Should I not try to do a Winclone image from the 2010 as is and restore to the 2015 as is??

    The goal is to avoid you having to redo the pruning on the 2015 Yosemite.

    If Yosemite restore causes the GPT/Disk formatting to be with the larger block size which mismatches the current 2010 Winclone, it may fail again. Using a FAT on the 2015 Mac will avoid such contamination/conflict by using a MBR only disk for testing.

    Another small issue is the 2010 bootcamp image is 265GB (used under 150GB)

    only want to use 200GB for 2015

    I guess that can be handled easily in Winclone, and there must be a safe way to adjust partitions in disk utility after the fact as well...

    You can shrink Winclone images. Your fsutil output is as expected on the 2010. We want to check on the 2015 as well, after the restore.

    Do I need to run sysprep or chkdsk again (ran a couple days ago) or create the Winclone image? Or next step, both Mac partitions time machined and 2010 windows 8.1 is system imaged.

    Unfortunately, no. Please also be aware that your installation on the 2010 has a Hybrid MBR and is a legacy BIOS/MBR installation. 2015 Macs will cause problems with such installations. W7 support on 2015 Macs has been deprecated because of this.
