Loner T, can you help me out man?

Question

Hey. I saw your posts for bootcamp issues, and you seem to really know what you&#x27;re doing. I updated my bootcamp partition from 7 to 10, then used Mini Partition Tool to reallocate space to the partition. Then, I did a fresh install of OS X. It still lets me boot from the partition if I restart the computer, but I have to use the option key every time. When I boot from OS X, the partition just shows up as disk0s4 and is unmountable. I&#x27;d like to make some changes and set the computer up to boot from Windows every time. After reading the forums that you posted in about the bootcamp repairs, I only felt confused. Could you give me a walk through on what I need to do to repair everything?

Let us start with some partition information. Please post the output of the following OSX Terminal commands.diskutil listdiskutil cs listsudo gpt -vv -r show /dev/disk0sudo fdisk /dev/disk0The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

The gap between GPT3 and GPT4 indicates a lost NTFS header. Can you use Lost my Windows 7 Boot Camp partition after upgrading to Yosemite. Help! as a reference, download Testdisk and GPT Fdisk and start a Testdisk scan?

Sorry for the delay. I was at work. On that page, do I need to run the commands that are in the solution, following each in the order they&#x27;re given?

This is correct. If you notice, the two Bootcamp entries match what you currently have. Please run a Quick Search. You will first get a list of unrecoverable partitions. Press Enter to Continue and then post a screen shot of recoverable and viable partitions.

Hit Escape (only once) and go back to the previous screen.

Jsaktony · Answer

Escape isn&#x27;t doing anything for me and I don&#x27;t see another option to go back. I can just go through it again?

Loner T · Answer

Here is a partition table based on what you have so far.Use &#x27;P&#x27; to list files when you get back in to the same screen using this specific NTFS start. The next one is 7 sectors aways which is likely to be corrupted.You are looking for something similar to
