Windows Bootcamp will not boot after resizing partition with OS X Disk Utility - El Capitan

Question

Hello https://discussions.apple.com/profile/Loner+TYou seem to be the knowledgable one to fix these issues!Can&#x27;t boot into windows after resizing partitionsI am not completely following the process of what may be different with my disk partitions and geometry so thought I would ask before I make things worse. Here&#x27;s the output to the commands you referenced in several posts (and this is not a MacBookPro, rather disk was once cloned from a MacBookPro but now is MacMini).  Can you please guide me on what the appropriate steps would be?Jeremys-MacBook-Pro:~ jeremy$ diskutil list/dev/disk0 (internal, physical):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                        *256.1 GB disk0   1:                        EFI EFI                     209.7 MB disk0s1   2:                  Apple_HFS SSD                     161.0 GB disk0s2   3:                 Apple_Boot Recovery HD             650.0 MB disk0s3   4:                  Apple_HFS Untitled                9.1 GB     disk0s4   5:       Microsoft Basic Data BOOTCAMP                85.0 GB    disk0s5Jeremys-MacBook-Pro:~ jeremy$ diskutil cs listNo CoreStorage logical volume groups foundJeremys-MacBook-Pro:~ jeremy$ sudo gpt -vv -r show /dev/disk0Password:gpt show: /dev/disk0: mediasize&#x3D;256060514304; sectorsize&#x3D;512; blocks&#x3D;500118192gpt show: /dev/disk0: PMBR at sector 0gpt show: /dev/disk0: Pri GPT at sector 1gpt show: /dev/disk0: Sec GPT at sector 500118191      start       sizeindexcontents          0          1         PMBR          1          1         Pri GPT header          2         32         Pri GPT table         34          6                  40     409600      1GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B     409640314447872      2GPT part - 48465300-0000-11AA-AA11-00306543ECAC314857512    1269536      3GPT part - 426F6F74-0000-11AA-AA11-00306543ECAC316127048 17713336      4GPT part - 48465300-0000-11AA-AA11-00306543ECAC333840384     262144         334102528166014976      5GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7500117504        655         500118159         32         Sec GPT table500118191          1         Sec GPT headerJeremys-MacBook-Pro:~ jeremy$ sudo fdisk /dev/disk0Disk: /dev/disk0 geometry: 31130/255/63 [500118192 sectors]Signature: 0xAA55         Starting       Ending#: idcylhd sec -cylhd sec [     start -       size]------------------------------------------------------------------------1: EE 1023 25463 - 1023 25463 [         1 -500118191] &lt;Unknown ID&gt;2: 00    0 0 0 -    0 0 0 [         0 -          0] unused      3: 00    0 0 0 -    0 0 0 [         0 -          0] unused      4: 00    0 0 0 -    0 0 0 [         0 -          0] unused      Jeremys-MacBook-Pro:~ jeremy$ sudo dd if&#x3D;/dev/rdisk0s5 count&#x3D;1 2&gt;/dev/null | hexdump -C00000000eb 52 90 4e 54 46 53 2020 20 20 00 02 08 00 00|.R.NTFS    .....|0000001000 00 00 00 00 f8 00 003f 00 ff 00 00 00 ea 13|........?.......|0000002000 00 00 00 80 00 80 00ff 2f e5 09 00 00 00 00|........./......|0000003000 00 0c 00 00 00 00 0002 00 00 00 00 00 00 00|................|00000040f6 00 00 00 01 00 00 00e2 c5 2c 6e fd 2c 6e e8|..........,n.,n.|0000005000 00 00 00 fa 33 c0 8ed0 bc 00 7c fb 68 c0 07|.....3.....|.h..|000000601f 1e 68 66 00 cb 88 160e 00 66 81 3e 03 00 4e|..hf......f.&gt;..N|0000007054 46 53 75 15 b4 41 bbaa 55 cd 13 72 0c 81 fb|TFSu..A..U..r...|0000008055 aa 75 06 f7 c1 01 0075 03 e9 dd 00 1e 83 ec|U.u.....u.......|0000009018 68 1a 00 b4 48 8a 160e 00 8b f4 16 1f cd 13|.h...H..........|000000a09f 83 c4 18 9e 58 1f 72e1 3b 06 0b 00 75 db a3|.....X.r.;...u..|000000b00f 00 c1 2e 0f 00 04 1e5a 33 db b9 00 20 2b c8|........Z3... +.|000000c066 ff 06 11 00 03 16 0f00 8e c2 ff 06 16 00 e8|f...............|000000d04b 00 2b c8 77 ef b8 00bb cd 1a 66 23 c0 75 2d|K.+.w......f#.u-|000000e066 81 fb 54 43 50 41 7524 81 f9 02 01 72 1e 16|f..TCPAu$....r..|000000f068 07 bb 16 68 52 11 1668 09 00 66 53 66 53 66|h...hR..h..fSfSf|0000010055 16 16 16 68 b8 01 6661 0e 07 cd 1a 33 c0 bf|U...h..fa....3..|000001100a 13 b9 f6 0c fc f3 aae9 fe 01 90 90 66 60 1e|.............f&#x60;.|0000012006 66 a1 11 00 66 03 061c 00 1e 66 68 00 00 00|.f...f.....fh...|0000013000 66 50 06 53 68 01 0068 10 00 b4 42 8a 16 0e|.fP.Sh..h...B...|0000014000 16 1f 8b f4 cd 13 6659 5b 5a 66 59 66 59 1f|.......fY[ZfYfY.|000001500f 82 16 00 66 ff 06 1100 03 16 0f 00 8e c2 ff|....f...........|000001600e 16 00 75 bc 07 1f 6661 c3 a1 f6 01 e8 09 00|...u...fa.......|00000170a1 fa 01 e8 03 00 f4 ebfd 8b f0 ac 3c 00 74 09|............&lt;.t.|00000180b4 0e bb 07 00 cd 10 ebf2 c3 0d 0a 41 20 64 69|............A di|0000019073 6b 20 72 65 61 64 2065 72 72 6f 72 20 6f 63|sk read error oc|000001a063 75 72 72 65 64 00 0d0a 42 4f 4f 54 4d 47 52|curred...BOOTMGR|000001b020 69 73 20 63 6f 6d 7072 65 73 73 65 64 00 0d| is compressed..|000001c00a 50 72 65 73 73 20 4374 72 6c 2b 41 6c 74 2b|.Press Ctrl+Alt+|000001d044 65 6c 20 74 6f 20 7265 73 74 61 72 74 0d 0a|Del to restart..|000001e000 00 00 00 00 00 00 0000 00 00 00 00 00 00 00|................|000001f000 00 00 00 00 00 8a 01a7 01 bf 01 00 00 55 aa|..............U.|00000200Thanks for any help!

Please see [Help] Can&#x27;t boot to windows (8.1) after resizing partition as a reference, and re-create a MBR using GPT 3 4 5.

Sure, it&#x27;s an Apple Mac mini (Late 2012)  6,2 - OS X El Capitan 10.11.3.My Windows partition was running out of space so I adjusted the partition in OSX by reducing it 10GB so I would have 10GB more in WIndows.. So was not a new partition just trying to increase the size.  I increase Windows partitions regularly in VMware ESX, so I didn&#x27;t realize the OS X DU would be so problematic.. I can still see all the files on the Windows partition once booted back into OSX.  But there is no longer an option to boot to Windows and when rebooting get non bootable partition error.  Thanks!

In the same link, there is a method I have outlined to absorb the 9GB partition into Windows.The following steps are executed when booted in OS X. If the 79G is converted to Free Space, these numbers (3 4 5) will change back to (2 3 4).You will need to use GParted and the method outlined in Using GParted to Resize Your Windows 7 or Vista Partition . This works on W8.1 and W10 as well.

Can you confirm the year/model of your Mac (do not post the serial number) and the macOS version? What was the reason to create a partition?

Thank you very much that fixed my issue.  I now have an ~8-9GB partition that is not used/usable? (cannot extend disk in Windows because of location of partition) but Windows is working again!
