You will need two software applications.

1. Testdisk (http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step) to locate the 'lost' NTFS partition which is currently located in the gap between GPT3 and GPT 4. It should between sectors 237011320 and 75605640.

2. Once the partition is located GPT Fdisk (http://sourceforge.net/projects/gptfdisk/) is used to manipulate GPT4 to allow Windows to boot. There is a thread that you can use a reference Bootcamp disk0s4 gone after Yosemite update.

3. In Testdisk use the highlighted partition type.

4. The 'lost' NTFS partition should be similar to the following...

Can you use 'P' command to list files in partitions which are MS Data and roughly the size of 210155513? The gap and GPT4 roughly add up to 251385480 sectors.

Do not use left/right cursor/arrow keys in Testdisk, just use up/down keys and use 'P' to list files.

Yes, you can recover this.

GPT 3 Start GPT 3 Size GPT 3 End NTFS Start Sector Offset NTFS Size NTFS End

235741784 1269536 237011320 278241280 41229960 210155513 488396792

The 'Sector Offset' being positive is good. A negative value means you lose GPT#3. The NTFS size is roughly 105GB which is good. The one bothersome fact is that you will still have a gap of 41229960 sectors, which is roughly 20GB. Was this what you intended to extend your Windows partition by?

A. You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.

Rebuild GPT4 using start/end offsets

Sudo gdisk /dev/rdisk0

P (print the full list of parts)

D (delete)

4 (part 4)

N (new part)

4 (part 4)

278241280 - Start offset in bytes (start point for Bootcamp part)

+210155513 (Size offset as opposed to End offset)

0700 (Windows part type)

P (print list of all parts just to see what changes will be made)

W (Write the new GPT)

Y (Yes! really write the new GPT)

This will delete and re-write the GPT partition info for /dev/disk0s4.

B. Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes).

Sudo gdisk /dev/disk0

P (Print list of parts)

R (Recover)

H (chooses Hybrid)

Partitions numbers to be hybridized: 2 3 4

Y (Good for GRUB question)

N (part 2 boot flag)

N (part 3 boot flag)

Y (part 4 boot flag make NTFS bootable partition)

W (Write the new MBR)

Y (Yes! write the new MBR)

Reboot

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

If you see a hanging underline cursor at the top left on a black screen, and it does not proceed further, you may need Windows Startup Repair or a tool called EasyBCD.

Thank you very much Loner T!!! You are the best. My son's mine craft saves are recovered 🙂

Yes that small space is what i wanted to extend to my windows partition. Can i still do it in windows using partition mini? Thanks a lot

It is not recommend that the Windows partition be resized. The most reliable tool (and it is a commercial tool) is called Winclone. It can also backup/restore Windows or move it to different drives, etc.

If you are willing to spend the money, I highly recommend it - https://twocanoes.zendesk.com/hc/en-us/categories/200158478-winclone.

Another tool is GParted. It is a partition editor and it is free, but requires a little bit more work.

The primary challenge with all such tools is keeping the GPT and MBR in sync and keeping the bootability of WIndows intact.

Thanks for the response.

Lucky was able to resize with partition mini, really need it cause the windows partition is already too small.

l also just backup the important files like the saves.

In another note, is there an easy way to clone the whole HD and copy it to a new one.

I want to purchase a new bigger HD so i can avoid this resizings. Thanks again for your help.
