Windows Partition gone after updating to Yosemite

Hello I have recently updated to Yosemite and was unaware of the bug that causes the partitions to disappear.
I have read threads and the steps are way too difficult to understand and all i see is coding and other things.
If anyone could help please (step by step) in a simple way.
Windows 7 Partition shows up as disk0s4.
Macbook Pro 13' in 2012.
Have downloaded TestDisk but have no knowledge in how to use it.

And I have a couple of questions to the steps below:
1. Delete the old entry and create a new entry at GPT#4. (Is this step done in testdisk? If it is, what are the steps to get to this step?)
sudo gdisk /dev/disk0
p
d
4
n
4
86923264
538218489
0700
p
w
y
2. You will need to reboot after the change, because the disk you are booted from is the one being modified. Reboot will rebuild disk0s4 using the start/end you entered.
3. Run the dd command - sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C and check that the first line contains "R.NTFS". (Done in testdisk?)
4. This is a tedious process and you want to check after the second 'p'rint command that it looks reasonable, before the 'w'rite and 'y'es to confirm. (Testdisk?)
5. Once you a working GPT#4, a new hybrid MBR needs to be created which will overwrite what you see in your Fdisk output. This is also done using GPT Fdisk (Gdisk). (Download link to Gdisk?)
6. a. Test 1 - Can you see your Bootcamp volume in Finder.
    b. Test 2 - Can you files in the Bootcamp volume?
    c. Test 3 - Can you see Bootcamp in your System Preferences -> Startup Disk.
    d. Test 4 - If Test 1-3 are successful, select Bootcamp and click on Restart. You may need Windows startup repair, if you see a hanging underline cursor at the top left corner of your screen. In most cases, it is not required.

Windows 7 Partition Gone After upgrade to Yosemite

So as many people are experiencing after I upgraded to Yosemite I lost my windows Partition. Holding Cntl on boot shows no windows option to boot from. When going to disk utility on the mac side, the windows partition is still there but showing a weird name disk0s4. It is grayed out and I cannot touch it.
At this point I just want to salvage my data from that partition. Please tell me that is possible. I Created a new thread because I am really a complete noob with Macs and a lot of whats in the other threads is foreign language to me. So I need help step by step what to do and where to go.
I am hoping I can salvage all my important data, then just reformat the old windows partition.
Much appreciated for the help and input.

I tried TeskDisk and from the very beginning it mentioned about being unable to modify my hard disk as below.
=========
Write access for this media is not available.
TestDisk won't be able to modify it.
- No partition from this disk must be mounted:
Open the Disk Utility (In Finder -> Application -> Utility folder)
and press Unmount button for each volume from this disk
- This media may be physically write-protected, check the jumpers.
==========
I tried the Disk Utility but of course I couldn't unmount the Macintosh HD partition while running on it.
Anyway, I still ran TestDisk to see if all partitions would be detected correctly. It seemed good, as captured below.
All the partitions were found. Then I chose MS Data partition, keyed P and Enter to check its filesystem.
The error message was same as described in the step by step guide you sent me.
The I went back and tried Deeper Search.
It run for hours any the analyse sector was strange at the end, something like more than 600,000,000/488,397,167. Sorry I forgot to capture this figure. However, I think Deeper Search is unnecessary if TestDisk can find all partitions.The problem is write access.
Regarding GPT FDisk (gdisk-0.8.10), after installing it I can't find where it is on my computer.
Do you have any recommendation please.

Cannot boot to Windows 8.1 after updating to Yosemite

I am using a MacBook Pro (Retina 13-inch Late 2013) computer, and mainly use Windows 8.1 via bootcamp on it for work. I have just updated OS X Maverick to OS X Yosemite 10.10, and now when booting and holding option, the Windows and Backup partition no longer show.
I have read a few threads on here with similar problems, and I believe that I understand the crux of the problem, but I am having difficulties actually using TestDisk as I'm not exactly sure what options to use and what to look for.
Below is a screenshot of my Disk Utility:
And here is the output of TestDisk so far (I analyzed the disk0):
It looks like the Bootcamp partition is still there, but I'm not sure what steps to take next -- any help would be most appreciated!

The deep search finally finished:

Windows 7 Bootcamp is no longer available in startup after updating to Yosemite 10.10

I updated my MacBook Pro (Retina, 15-inch, Late 2013) and then after updating I could no longer see my Windows 7 bootcamp when starting up. I followed this tutorial to try to get it too work again without losing any information: Windows 7 Removed after update Yosemite. I got to the part where we rebuild the MBR, but I got to part 8 and then it said that partition 4 is either too big or does not exist.
I do not know what to do from here and was wondering if I had done something wrong and/or what I can do to fix it?
Thanks in advance

You seem to have found the correct partition. The following table has your values. (ASC thinks I have invalid characters in my table, so this is a screen shot of the MS Excel spreadsheet).
Leave your Testdisk display and start a new Terminal Window. 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)
589682688 - Start offset in bytes (start point for Bootcamp part)
+387422201 - (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.
Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 6. Accept all other defaults that Gdisk offers.
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
Here is a sample Q and A for the second set of Gdisk steps.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #2 (MBR partition #2)
Enter an MBR hex code (default AF): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #3 (MBR partition #3)
Enter an MBR hex code (default AB): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #4 (MBR partition #4)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): 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.

After updating to Yosemite, why will my windows in Safari and Microsoft Word close unexpectedly with no method of retrieval?

On two different occasions after updating to Yosemite this has happened. On the first occasion I had two documents open in Microsoft Word and after looking something up on Safari, attempted to go back to the two open documents. Microsoft Word was showing as open, but the documents were nowhere to be seen and I also could open nothing else and was forced to force quit without saving my work on those documents.
A similar thing occurred today with Safari. I had many tabs open in one window in Safari. I closed my laptop to move to another room, and upon opening my laptop again Safari was still open, but all my tabs of different research papers I had were gone. When I chose the "reopen all windows from last session" option, it reopened windows I had not had open for many days, and not the ones I had been working off that day.
This is extremely annoying and as a scientist, I was forced to once again look up the many papers I needed for a grant proposal that I had not yet copied down reference information for. Why is this happening?

I see you have used Clean My Mac. If you search these forums you will find that running apps like this can cause problems. Start with this link:

Can you reboot the computer to Snow Leopard? If so, then re-run the Yosemite installer application. It should be in your Applications folder.
If you can't, then you need to erase the drive and reinstall Snow Leopard:
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.

Cannot download Iphoto after updated to Yosemite

I cannot update Iphoto anymore after updated to Yosemite. The system popped up a small window and showed that: update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled. But it is my own account, I just changed the password.
Please help me to solve this problem.

That means, that your AppleID is not associated with the iPhoto version you have installed.
Which version of iPhoto do you currently have? Sign into the App Store with your Apple ID (in the Store" menu).
If iPhoto came preinstalled on your Mac, check the "Purchases" tab of the App Store, if there is an "Accept" button besides iPhoto. If yes, accept iPhoto to associate it with your Apple ID. Then try again to update.
If that does not work, uninstall iPhoto - move the iPhoto app from the Applications folder to the Trash and then go to the "Featured" tab of the App Store, search for iPhoto using the Search field, then press the "Get" button to install iPhoto again, this time with your current AppleID:

After updating to Yosemite brush stops / lags

After updating to Yosemite whenever I am using brush or the eraser tool it stops or lags (I am not sure what to call it).
What happens is I can't hit any other shortcuts keys like "[ ]" for increasing the brush size and even changing tools like pressing "V" but if I click the icon it will be picked.
I checked the history panel it also stops there.
I am using
Wacom Bamboo CTH-670
Wireless keyboard
Wireless Mouse
iMac (21.5-inch, Mid2010)
I also did these things
- Reinstalled photoshop and driver of Wacom
- Used the brush in Lightroom (it works perfectly there but not in photoshop)
- Using the clone stamp tool like a brush it works perfectly.
What should I do now?

I couldn't see the clear Caches but it is okay now. I got the solution from another post and the solution was
"Are you running CS6? if so, go to Menus, shortcuts, Lasso tool, or Photoshop stop working when using a Wacom tablet | Mac OS
and install the white window workaround plug-in. Let us know if this clears up the issue"
Still I am thankful to everyone who came here.
Thank you!

MacBook Pro Battery Life Draining After Updating to Yosemite

Hi,
I have a 2011 MacBook Pro. After updating to Yosemite a few months, I have experienced a severe loss of battery life. I was averaging around 6-8 hours on a charge, and that is now down to about 3. I have reset the PRAM, etc. and SOMETIMES that will work but not always. I typically have only one program running at a time, Chrome, but sometimes it's a mix between Chrome, Windows, iTunes. But my computer usage patterns have not changed since before/after updating. The only thing I can think of is that it is caused by Yosemite.
When I check my Activity Monitor, the apps with the highest CPU usage are WindowServer, kernal_task, and Chrome Helper. I have also disabled several plugins/features of Chrome to no avail.
Has anyone experienced similar issues or have any suggestions?
Thanks!

Is one of the 'etc.' a SMC reset?

Netflix Streaming on MacMini does not work after update to Yosemite

Netflix videos will no longer stream :
I am using a MacMini (late 2012) with an HP w2207h display. Intel processor 2.5 GHz Core !5 Intel HD Graphics 4000 1024 MG After updating to Yosemite, 10.10.1, I cannot stream videos from the Netflix site.
All of the monitor specs. would indicate that streaming videos in HDCP would be possible. Everything streamed very well until approximately 4 days ago.
I have changed the display resolution to 1080p. I have disconnected the monitor and reconnected it several times. I have updated iTunes as well as Yosemite.

Have you went to NetFlix's support site?

I cannot run iPhoto after update to Yosemite. I cannot update iPhoto because the application store does not have any iPhoto update available. Anyone can advice how to overcome this hassle?

After update to Yosemite 10.10.3 the iPhoto program icon is banned and there is an error message that an update is required to run iPhoto, but the application store shows a message that iPhoto does not have any update available at this time. There is not even any iPhoto program available on the application store. Any suggestion on how to solve this annoyance?

Unfortunately, Apple has removed both iPhoto and Aperture from the Mac App Store so they cannot be downloaded anymore. This means you are forced to migrate to Photos (included in OS X 10.10.3) or, if this app does not include features you need, look for a different app.
Not true. Apple has removed both Apps from App Store so you cannot buy them anymore. But if you have any of these Apps already purchased in the past, then you can still download them on your Mac.

Open App Store, sign in with your Apple ID and go to Purchases tab. If you see iPhoto app listed there close down the App Store and do this steps as this is what worked for me:
Open Finder and go to Applications folder.
Locate iPhoto app
Drag iPhoto app from your Applications folder to Trash (NOTE: Do not emptied Trash yet)
Open App Store app and navigate to Purchases tab.
Click on Install button which is next to the iPhoto app (on the right hand side).
Once iPhoto is downloaded again, test it if its working for you. If all is ok, you can remove your Trash.

Scrubbing no longer works after updating to Yosemite

After updating to Yosemite yesterday and restarting this morning, I've noticed several problems. The biggest is that scrubbing in the timeline is very buggy, unresponsive, and sometimes doesn't work at all. I've tried turning it off and on, restarting FCP and my mac to no avail.
Also switching between tools via keyboard shortcuts and the playhead moving between edits have been sluggish as well. Library is stored on a thunderbolt connected RAID

My impression, from my own experience and paying attention to other users' issues, is that 10.1.3 running on 10.10 is generally the fastest, most stable combination since the application was first introduced. This weekend I did a full days work on a couple of unfamiliar systems, new iMacs with shared storage, over two dozen projects, and I encountered no glitches whatsoever.
So that's why I was interested in your media drive and whether there might be something in your user account that the OS or FCP was struggling with.
Here is a kind of check list that Richard Taylor compiled. Why not go through it to see whether you discover a remedy.
