Q: El Captain: windows 10 Bootcamp not recognizing after temporary partition

What is the year/model of your Mac? Please post the output of

sudo fdisk /dev/disk0

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

You are on El Capitan.

A. We need to disable SIP.

1. Boot into Local Recovery (Command+R).

2. Start Utilities -> Terminal.

3. Type csrutil disable in Terminal and press Enter/Return.

4. Type csrutil status.

5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.

B. Mark the NTFS partition bootable. Please ignore the i386 MBR error message, but not any others.

sudo fdisk -e /dev/disk0

p

setpid 4

07

flag 4

p

w

y

Reboot and test.

Excellent. Please back up OS X, Windows, and create a Windows System Restore Point .

Dear Loner T,

I do not know why I couldn't create a new post. So i just post at here.

I have tried the command you given in earlier post, but the window 7 drive didn't show up after i reboot and hold the ALT key.

sudo fdisk -e /dev/disk0
p
setpid 4
07
flag 4
p
write
y

FYI, I am using Macbook Air OS X El Capitan OS X 10.11.3 (15D21).

Hope to hear from you soon. Thank you.

Dear Loner T,

thanks for your help. I have solved the issue. The reason is I didn't boot to recovery mode.

Excellent. Please back up OS X, Windows and create a Windows System restore point.

Dear Loner T,

Do you know how to expand the bootcamp window 7?

I have tried by adjusting the partition in disk utility and it had cause the macbook air failed to boot the wind 7.

Loner T,

I have recently reduced my Macintosh HD by 30GB so that I could increase my bootcamp windows 10 HD by 30GB, but I cannot boot windows after restarting and holding the option key. I've been looking through several forums here, but not sure if my situation is the same, so I'm copying my terminal output here:
