Q: Repairing Boot Camp after creating new partition

I did the stupid thing to create a 3rd partition while having bootcamp..

I know there are very similar posts, but i need help to make sure to get it right repairing the MBR..(if possible?)

 

Here is the situation ( diskutil list, gpt, fdisk, gdisk results) I'll be very grateful if someone knowledgeable answer me... ( will i have the chance to get a response from Christopher Murphy...?)

A:

Try the simpler fix first. Please ignore the i386 MBR error message when you run the following commands.


sudo fdisk -e /dev/disk0

p

setpid 4

07

flag 4

Test 1 - Does Bootcamp Volume show up in Finder?

Test 2 - Can you see files in Bootcamp Volume?

Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?

Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.

    You need to find the 'lost' NTFS partition in the gap between GPT3 and GPT4. Can you use Boot Camp missing after upgrade as a reference and start a scan with Testdisk?

    The harddisk (251 GB / 233 GiB) seems too small! (< 1434 GB / 1335 GiB)

    Check the harddisk size: HD jumpers settings, BIOS detection...

    Can you post the output of

     

    sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

     

    What was the size of the new partition you were trying to create? Is it roughly 1.2 Gb?

    It xas a 30 Gb FAT partition, but I then try to remove it (could not), and then reduced it to effectively 1,2 Gb.

    Try the simpler fix first. Please ignore the i386 MBR error message when you run the following commands.


    sudo fdisk -e /dev/disk0

    p

    setpid 4

    07

    flag 4

    p

    w

    y


    Test 1 - Does Bootcamp Volume show up in Finder?

    Test 2 - Can you see files in Bootcamp Volume?

    Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?

    Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.

    Loner T, I owe you...a lot !

    Thank you so much being patient with a "first time posting on the net" guy...

    It works fine, I got back all my C++ and Java programing environnement under Windows...

     

    One thing, the 1, 9 Gb are unused, is it save to extend MAC partition to get all those bytes back ?

     

     

    THANK YOU SO MUCH !

    I kiss you (only if you are a pretty looking girl..)
