Q: Unaccessible Windows partition

Dear All,

 

I need help! I can't neither see me Windows partiton in Finder neither I can boot Windows. In the DiskUtility I get the following error: "invalid bs_jmpboot in boot block".

 

The command "sudo gpt -r -v show disk0" returns:

gpt show: disk0: mediasize=251000193024; sectorsize=512; blocks=490234752

gpt show: disk0: Suspicious MBR at sector 0

gpt show: disk0: Pri GPT at sector 1

gpt show: disk0: Sec GPT at sector 490234751
