Cannot boot win7 (bootcamp) after updating to high sierra

Question

Hi there.Today, after updating to high sierra I haven&#x27;t been able to boot into my win7 bootcamp.While holding &#x27;alt&#x27; it does show both, but after getting to the blinking &#x27;-&#x27; it doesn&#x27;t get any further. Usually it took around 1-2 minutes for it to show windows startup graphics but now it just keeps going. Tried letting it continue around 15min but nothing happens. In OSX I can still see the BOOTCAMP partition under &#x27;devices&#x27; in finder and the files still seem intact.Anyone else experiencing this?Maybe someone has an idea of what is happening?Kind Regards  Model Name:    MacBook Pro  Model Identifier:    MacBookPro8,2  Processor Name:    Intel Core i7  Processor Speed:    2,2 GHz  Number of Processors:    1  Total Number of Cores:    4  L2 Cache (per Core):    256 KB  L3 Cache:    6 MB  Memory:    16 GB  Boot ROM Version:    MBP81.004D.B00

I have replaced the original HDD with a 500 GB SSD.Also upgraded the RAMs.Afraid I don&#x27;t know what MBR is.sudo gpt -vv -r show /dev/disk0:gpt show: /dev/disk0: mediasize&#x3D;500107862016; sectorsize&#x3D;512; blocks&#x3D;976773168gpt show: /dev/disk0: Suspicious MBR at sector 0gpt show: /dev/disk0: Pri GPT at sector 1gpt show: /dev/disk0: Sec GPT at sector 976773167      start       size  index  contents          0          1         MBR          1          1         Pri GPT header          2         32         Pri GPT table         34          6                  40     409600      1  GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B     409640  798629848      2  GPT part - 7C3457EF-0000-11AA-AA11-00306543ECAC  799039488  177733632      3  GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7  976773120         15           976773135         32         Sec GPT table  976773167          1         Sec GPT headersudo dd if&#x3D;/dev/rdisk0s3 count&#x3D;1 2&gt;/dev/null | hexdump -C:00000000  eb 52 90 4e 54 46 53 20  20 20 20 00 02 08 00 00  |.R.NTFS    .....|00000010  00 00 00 00 00 f8 00 00  3f 00 ff 00 00 60 a0 2f  |........?....&#x60;./|00000020  00 00 00 00 80 00 80 00  ff ff 97 0a 00 00 00 00  |................|00000030  00 00 0c 00 00 00 00 00  02 00 00 00 00 00 00 00  |................|00000040  f6 00 00 00 01 00 00 00  29 c1 1a 0c f2 1a 0c 22  |........)......"|00000050  00 00 00 00 fa 33 c0 8e  d0 bc 00 7c fb 68 c0 07  |.....3.....|.h..|00000060  1f 1e 68 66 00 cb 88 16  0e 00 66 81 3e 03 00 4e  |..hf......f.&gt;..N|00000070  54 46 53 75 15 b4 41 bb  aa 55 cd 13 72 0c 81 fb  |TFSu..A..U..r...|00000080  55 aa 75 06 f7 c1 01 00  75 03 e9 dd 00 1e 83 ec  |U.u.....u.......|00000090  18 68 1a 00 b4 48 8a 16  0e 00 8b f4 16 1f cd 13  |.h...H..........|000000a0  9f 83 c4 18 9e 58 1f 72  e1 3b 06 0b 00 75 db a3  |.....X.r.;...u..|000000b0  0f 00 c1 2e 0f 00 04 1e  5a 33 db b9 00 20 2b c8  |........Z3... +.|000000c0  66 ff 06 11 00 03 16 0f  00 8e c2 ff 06 16 00 e8  |f...............|000000d0  4b 00 2b c8 77 ef b8 00  bb cd 1a 66 23 c0 75 2d  |K.+.w......f#.u-|000000e0  66 81 fb 54 43 50 41 75  24 81 f9 02 01 72 1e 16  |f..TCPAu$....r..|000000f0  68 07 bb 16 68 70 0e 16  68 09 00 66 53 66 53 66  |h...hp..h..fSfSf|00000100  55 16 16 16 68 b8 01 66  61 0e 07 cd 1a 33 c0 bf  |U...h..fa....3..|00000110  28 10 b9 d8 0f fc f3 aa  e9 5f 01 90 90 66 60 1e  |(........_...f&#x60;.|00000120  06 66 a1 11 00 66 03 06  1c 00 1e 66 68 00 00 00  |.f...f.....fh...|00000130  00 66 50 06 53 68 01 00  68 10 00 b4 42 8a 16 0e  |.fP.Sh..h...B...|00000140  00 16 1f 8b f4 cd 13 66  59 5b 5a 66 59 66 59 1f  |.......fY[ZfYfY.|00000150  0f 82 16 00 66 ff 06 11  00 03 16 0f 00 8e c2 ff  |....f...........|00000160  0e 16 00 75 bc 07 1f 66  61 c3 a0 f8 01 e8 09 00  |...u...fa.......|00000170  a0 fb 01 e8 03 00 f4 eb  fd b4 01 8b f0 ac 3c 00  |..............&lt;.|00000180  74 09 b4 0e bb 07 00 cd  10 eb f2 c3 0d 0a 41 20  |t.............A |00000190  64 69 73 6b 20 72 65 61  64 20 65 72 72 6f 72 20  |disk read error |000001a0  6f 63 63 75 72 72 65 64  00 0d 0a 42 4f 4f 54 4d  |occurred...BOOTM|000001b0  47 52 20 69 73 20 6d 69  73 73 69 6e 67 00 0d 0a  |GR is missing...|000001c0  42 4f 4f 54 4d 47 52 20  69 73 20 63 6f 6d 70 72  |BOOTMGR is compr|000001d0  65 73 73 65 64 00 0d 0a  50 72 65 73 73 20 43 74  |essed...Press Ct|000001e0  72 6c 2b 41 6c 74 2b 44  65 6c 20 74 6f 20 72 65  |rl+Alt+Del to re|000001f0  73 74 61 72 74 0d 0a 00  8c a9 be d6 00 00 55 aa  |start.........U.|00000200

No. Has the MBR been manipulated? Can you post the output of sudo gpt -vv -r show /dev/disk0sudo dd if&#x3D;/dev/rdisk0s3 count&#x3D;1 2&gt;/dev/null | hexdump -C
