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

    In theory, it reduces IO, but small file IO is negatively impacted with larger blocks.

     

    Is the previous output from the 2015 Mac?

     

    Device Block Size:        512 Bytes

    Allocation Block Size:    4096 Bytes

    Your NTFS file system is still using the 2010 settings and will not boot with the 2015 settings.

    Can you post it from the 2010 Mac? Is the 2010 Windows bootable? If yes, Boot Windows, and post the output of the highlighted command, similar to (use an Admin CMD window)

     

    fsutil fsinfo ntfsinfo c:

    Bytes Per Sector : 512

    Bytes Per Physical Sector : 4096

    Bytes Per Cluster : 4096

    Bytes Per FileRecord Segment : 1024

    Clusters Per FileRecord Segment : 0

    You have the same values on both machines. Did you try a Winclone restore with SIP in a disabled state?

    Just as an FYI I do CAD design and I do deal with multiple larger files(a few larger are 1MB-10MB) and hoping to maximize performance...if that really makes a difference in block sizing...

    I used a time machine backup in migration assistant setup.

    The other option is to abandon Winclone method, and re-install Windows from scratch. Be aware that you cannot re-install W7 on the 2015 Macs anymore.

    So the Winclone method is forcing the block matching? (even though it already is correct?) Is there a way from a time machine backup and do I want to change the 2015 block size to 4096?

    Why does my 2015 mac only allow FAT and not FAT32? And what about NTFS (I know Winclone will convert it to NTFS during a restore) how do you get it to NTFS without Winclone...

    Options are...

    Windows cannot use TM, but OSX can. OSX Migration Assistant should not format the disk. You can try only OSX Migration but erase/format the internal drive in Internet Recovery first and test.

    FAT vs FAT32 is just a nomenclature between 2010 and 2015 Macs. They should be FAT32 and diskutil info will tell you.

    If you are willing to install Windows on 2015 from scratch (assuming it is not W7), and then use Windows Migration (it will not migrate applications, but only settings and Documents), then you do have a method of using the 2010 information.

    I really really would not want to install windows and all my applications again, the CAD apps are very  convoluted...

    At this point with the block size is currently matching? Can I do a win clone image from the 2010 and restore it to the 2015 after I do a FAT partition?

    Please disable SIP on 2015 Mac first.

     

    1. Boot into Local Recovery (Command+R).

    2. Start Utilities -> Terminal.

    3. Type csrutil disable in Terminal and press Enter/Return.

    4. Type csrutil status.

    5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.

    I thought Yosemite didn't require that?

     

    larbars-MacBook-Pro:refit mbpro10$ csrutil status

    -bash: csrutil: command not found

    Did your 2015 Mac originally have Yosemite or did you get Yosemite as a TM restore?
