Can't boot Bootcamp any more

Hi I'm running OS X 10.11.6 with Win 7 (64).


The system was running perfect for years.

I reduced the size of my OS X partition using Disk Utility because I need more space on my Bootcamp partition.


After reboot ( holding "alt") the option to boot from the Bootcamp partition was not available any more.


I went back to OS, resized the OS X partition, next reboot - Bootcamp still not available.


In OS, using Disk Utility the Bootcamp partition is still visible.

This is what I can tell:


sudo gpt -r -vv show disk0

gpt show: disk0: mediasize=500107862016; sectorsize=512; blocks=976773168

gpt show: disk0: Suspicious MBR at sector 0

gpt show: disk0: Pri GPT at sector 1

gpt show: disk0: Sec GPT at sector 976773167

start size index contents

0 1 MBR

1 1 Pri GPT header

2 32 Pri GPT table

I've scanned a lot of the posts here, but I didn#t find a solution (am I to blind?).

Does this mean that the ID for partition #4 has to be changed to "07"?

Thanks in advance regarding suggestions.
