Lost bootcamp windows disk partition after mountain lion installation

Greetings all!
So I've had Bootcamp (windows 7 and snow leopard, 125gb of hard drive storage on each) on this MacBook Pro (late 2010) for over 2 years and I decided to upgrade to mountain lion.
As we all know that we can partition the disk under windows into smaller volumes, often labeled as C:, D:, E:, etc. my friend divided the hard drive storage for Windows into C: and G: when I first had windows 7 on my MacBook Pro 2 years ago.
The problem emerged after I installed mountain lion couple days ago. I'm still able to choose the system I want it to run after i press and hold "option" key and it will log on windows without any problem. My windows desktop looks the same as what it was before installing. HOWEVER, my partition G: totally disappeared! Partition C: remains the same. I'm pretty sure that G: is still somewhere in the hard drive because the system tells me that out of 125GB of storage for windows, 50GB is used, which is the size of C:, and available is only 10GB! So the difference of about 60GB must have been taken by the lost partition G:. I tried searching specific files that I have in G: under windows but it returned me no results. So I'm thinking it might be virtual somewhere. The files in G: are very important to me, so I'm looking for help/suggestions here to restore that partition by all means.
Thank you very much for taking the time reading my post and I'm really looking forward to your reply!

Ok, I just found a way out this nightmare. The problem is that for a unknown reason, the password has to be entered as if it had been originally entered on a US keyboard layout (QWERTY)... So I had to find which keys I would have stroke if I had entered my password on a US keyboard thinking it was a FR one (AZERTY).

2008 iMac won't turn on after Mountain Lion installation

I have a 2008 iMac with 6GB of RAM that was running on OS X 10.6.8 perfectly. Tonight I upgraded it to Mountain Lion. After the installation, my machine was running slower and a little choppy, especially when first opening programs, even though it meets all the requirements for Mountain Lion. After about an hour or two of running like this, I was standing away from the computer for a minute when I saw a flash come from the monitor. I went to it and the screen was black. I thought maybe it had went to sleep, but nope! It was completely off and would not turn back on. No lights or sounds come on at all. There was no power outage or anything, and all other devices plugged into the same surge protector were working fine. I tried plugging it into another outlet and still had no luck.
Any insight onto what caused this? Is it most likely a power supply failure, and could this have been caused by the Mountain Lion installation? Considering I've had this computer for almost 5 years and this has never happened before, it seems obvious that this contributed somehow.
Any advice would be appreciated. I'm going to try to take it to an Apple store soon, but the earliest appointment is a few days away.
Thank you!

Welcome to Apple Support Communities
It's quite possible that the power supply failed. The failure is difficult to be related with OS X Mountain Lion, so I would discard that. In some cases, it's normal that you experience slowness after installing a new OS X version because Spotlight indexes the hard drive.
The best you can do is to take it to an Apple Store or reseller so you can get your Mac diagnosed. Now we can't do anything else apart from thinking that is a power supply issue

MacBook Pro runs slow after Mountain Lion installation

I have a mid-2009 13" MacBook Pro with 2.2g Ghz processor, 2 GB of RAM and 160 GB encrypted disc.
After installing Mountain Lion and the recent upgrade OS X 10.8.1 (12B19), the system runs noticibly slower than with Lion, which ran slower than the previous version. This shows up in opening and closing programs, rate that drop down windows appear when something is clicked on the task bar, rate that windows open and close, rate that the dock comes up and the icons expand when the curser is moved over them, etc.
Due to my type of work, I need to encrypt the disc. I know this is costing me some speed. I unencrypted the disc and it ran noticably faster, and when I re-encrypted it seemed to run faster than before unencrptying and re-encripting. I have repaired permissions and verified the disk OK.
Somewhere in the build up to Mountain Lion release I thought I read where 4 GB of ram was recomended for Mountain Lion, allthough now the specs indicate 2 GB is OK. In activity monitor, the pie chart for system memory seems to always remain less than about 40% of active memory (yellow).
What recomendations does the community have to increase the speed of operations back to when this system was new?
Dave

I was having the exact same problem. My MacBook Pro was seriously close to unusable how slow it was. On a different thread, someone recommended I reset the VRAM and PVRAM (not sure about those initials). Shut down computer. Rebooted while holding down Command-Option-P-R all at the same time until I heard the second startup tone and then released. I noticed an improvement in performance immediately.

Existing IMAP notes not available in notes app after mountain lion installation

After today's mountain lion upgrade (from lion) my notes stored on an IMAP server are not available in the new notes app. The folder of the IMAP Account itself is shown but appears empty. On my Iphone all notes of the IMAP Account are shoen correctly as well as on another mac still running lion.
Any Suggestions?
Thanks in advance.

Okay, I assume there are some different reasons for the syncing problem.
I got my notes syncing again by just losing the prefix on my iPhone and renaming the existing notes folder. For those with a similar problem, here's how:
Old situation:
Within OS X Lion I used a Gmail account with notes (IMAP). To avoid a messy layout with the Gmail folders I used [Gmail] as IMAP Path Prefix (found under Accounts, tab Advanced).
Under iOS5, 'Notes' was ticked on under the Gmail account. The result: Apple created a IMAP folder '[Gmail]/Notes' to store all notes.
New situation:
After upgrading to OS X Mountain Lion I ticked 'Notes' under the Gmail account within system prefs, 'Mail, Contacts & Calendars'. The new Notes app remained empty and didn't show my existing notes that were still on my iPhone.
Logging in to www.gmail.com reveiled a new folder created by Mountain Lion: 'Notes'. The existing notes folder was named '[Gmail]/Notes' - because I used the [Gmail] prefix - and contained al the existing notes.
So Mountain Lion syncs with the IMAP folder 'Notes' and the iPhone syncs with the folder '[Gmail]/Notes'
In Lion the Mail settings were used for both Mail and Notes. So the IMAP prefix applied to both.
In Mountain Lion, the IMAP prefix only applies to Mail, not to Notes.
New situation, fixed:
As Mountain Lion can only use a folder called 'Notes' for syncing, I had to change the folder my iPhone was syncing with: '[Gmail]/Notes'. I removed the newly created folder 'Notes' via www.gmail.com under the label settings and renamed label '[Gmail]/Notes' to 'Notes'. After that I removed the IMAP prefix '[Gmail]' from my iPhone Gmail (advanced) account settings, making the iPhone sync notes with the folder 'Notes' instead of '[Gmail]/Notes'. That's it.
Btw, I maintained the use of the prefix within Apple Mail under Mountain Lion as that is totally separated from the Notes section.
Hope this helps.

After Mountain Lion installation a new folder does not open

After installing Mountain Lion when creating a new folder in my home folder the new, empty folder will not open correctly. When double clicked, the new, empty folder shows the other folders in my home folder not an empty folder. The icons displayed also get slightly smaller.
If the newly created folder is clicked once it remains selected until a new selection is made in the sidebar. Doing this also does not allow any other folder in the home folder to be selected.

Same type of problem as described in this thread:

System Crash Screen after Mountain Lion Installation

I tried to install Mountain Lion on 2 different MacBook Pro Laptops, one newer 15" running latest version of OSX Lion and the other a 13" running latest updated OS as well. I can download the software, it goes through download, starts the app, I get the app started on the install and then let it do it's thing, when I return to check on it I get a screen full of numbers and text with the error message that states you have to press and hold power to turn off. The same kind of screen you get when your system crashes and can't run.
Not sure if it's when it's trying to reboot or if its when the OS is installing. I run little snitch and gave the app full access on all ports to the Internet, but not sure. The 13" MP wasn't connected to anything except a LAN cable, no external monitor or keyboard or even a mouse. Just the laptop itself.
The 15" is connected to display, keyboard, mouse and an external hard drive.
The only way I was able to fix, was to reboot using Command R to get into recovery mode and restore from backup using Time Machine worked perfectly fortunately.
Any ideas on why it wouldn't install? or how to fix?
I even made sure to close down all applications first prior to installing.
The only thing I didn't do was to disable Time Machine, not sure if it tried to kick off during the installation and that made it crash or not?

I disabled Time Machine and tried it again. This time I watched it. It ran the first part of the application and then rebooted. When it rebooted it came up with the following text screen with the window to reboot hold down power button:

Macbook Pro won't reboot after mountain lion installation.

I installed the new Mountain Lion o/s and the installation was sucessful. However, when the computer started to
reboot by itself, it just stuck on the grey screen with the logo and the turning wheel. It has been like this for hours.
What should I do to fix this problem? Please help. The computer was purchased during Christmas 2011.

Call Apple support and they can talk you through getting back to a restore.
It appeared that my disk was a little corrupt before performing the upgrade. You should use diskutility to verify and repair your disk before doing this upgrade.
Or just hold the option key down on boot up to see if you can get to the restore utility.

IMac powers off in sleep mode after Mountain Lion installation

After I installed Mountain Lion on my 2010 iMac, it will power off after I don't use it a while. It used to just go to sleep, I'd shake the mouse, and it would come back up. Now it powers off and I have to power it back up every time.
My Macbook has NOT had this problem since Mountain Lion install. It is fine.

Try doing a smc and pram reset.

2010 Mac Mini display and network issues after Mountain Lion installation

I just installed Mountain Lion on my 2010 Mac Mini, but now the display won't work and it isn't showing up on my network. I have it hooked up to my TV (I don't have another screen for it) via HDMI. Also, I've mainly used this computer by using the share screen function with my laptop, so I don't have a keyboard or mouse for it either. The Mini is no longer showing up on my laptop's network list... Any suggestions?

I would see if you borrow a USB keyboard and mouse
from some one, because otherwise trouble shooting the
problem will be next to impossible as sometimes the fixes
and diagnostics require the keyboard (PRAM reset, Hardware
Test, etc.).

Youtube doesn't work after Mountain Lion installation

I recently installed Mountain Lion on my iMac. Since then the Youtube website will not open when on wifi. It will open when ethernet is connected. This is the only site that seems to be affected. It stalls for a second or two, then I get a blank screen and the URL changes to www.youtube.com/?tab=w1. I read through every forum I can find, tinkered with the network settings, deleted cache files for the browsers, etc. Firefox, Safari and Chrome all do the same thing.

"Repair disk" when installing Mountain Lion

I was just upgrading to Moutain Lion OS X right now when it tells me my disk needs repair. I tried, but it says "Macintosh HD couldn't be verified properly" (might not be exact wording, it's in Norwegian for me). When I click the "repair disk" button nothing happens, it just gives me the same message.
What are my options? I do have a back up (time machine), BUT it's from 2 years ago and thus I'd be losing a lot of files I have on here since after then, and that would really suck..

Then quit the Mountain Lion installer. Do you have a bootable system on your external hard drive? If so, then boot from it as follows:
Boot Using OPTION key:
Restart the computer.
Immediately after the chime press and hold down the "OPTION" key.
Release the key when the boot manager appears.
Select the desired disk icon of the external HDD.
Click on the arrow button below the icon.
Once you have booted from the external drive do the following:
Repair the Hard Drive and Permissions
Open Disk Utility from the Utilities folder. After DU loads select your internal hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Restart the computer. Locate the Mountain Lion installer in the Applications folder. Now see the following before proceeding if you want to make a bootable USB flash drive installer:
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.

Slow internet after mountain lion download

web pages open slowly or not at all after mountain lion download

I'm having the same problem but only at home with a slow internet service. At work with faster internet my macbook pro works fine. I wonder if Mountain Lion requires some minimum internet speed? Our old macbook pro (not using Mountain Lion) still works fine with our slow home internet. This change happened when I installed Mountain Lion. Also I can boot from by back up disk and bypass Mountain Lion and work with my slow internet at home. ???

Strange Application Issues after Mountain Lion Upgrade!

I'm having, what I believe to be, strange issues with a clean install of Mountain Lion from 10.6.8
It's for my boss' computer at work so I can't afford to have it down for very long at a time. It's hard to pinpoint the issue(s).
Computer:
Mac Pro - Early 2009
OS X 10.8.3
2 x 2.6 GHz Quad-Core Intel Xeon
32 GB 1066 MHz DDR3
The startup disk is 4x2TB RAID 5 using Apple RAID card (Firmware version: E-1.3.2.0; Hardware Revision: 2.00; Driver version: 124
The following is what happened/is happening:
1. (Tuesday)
Created a bootable backup of system drive using Disk Utility
Performed a Clean install
Used migration assistant to copy over applications from backup
Downloaded (from Amazon) and installed Microsoft Office 2011
Imported Addresses (including imported Previous Recipients that were imported into Contacts before exporting on old system)
Setup email & copied over mailboxes from backup
Moved all files back onto the system (User folders)
Everything worked fine from Wednesday - Sunday.
Problems reported to me (Sunday)
"Chinese characters" on save dialogue box in Microsoft Excel
Mail crashed while dragging a photo from safari to it
After a restart, Mail, all Microsoft Office apps, and Final Cut Pro wouldn't open.
Tried to reset preference files, but nothing worked.
2. (Monday night)
Performed another Clean Install
Migrated Applications
Transferred mailboxes (not old emails at this time)
Imported same group of addresses as before into Contacts
Installed Microsoft Office
Moved user data back
Transferred old email mailboxes (Tuesday afternoon)
Everything worked fine Tuesday - Thursday early morning)
Problems reported to me (Thursday morning)
When typing in an email address to send an email, it didn't autofill. Mail crashed.
Mail wouldn't open. Different from last, this time it said the ~/Library/Mail folder was moved. I checked and the folder was there with everything in it fine.
The Microsoft applications that were open at the time of the Mail crash still worked, but others wouldn't open. After closing the open applications then they wouldn't open back up (same as before)
Final Cut Pro opened fine.
Fixed Mail by deleting the ~/Library/Containers/com.apple.mail folder.
Later found out that though Final Cut would open it would crash when loading a project and that Quicklook wouldn't work for quicktime files across the network & codecs were missing (this could have been cause by me when trying to test problems).
3. (Sunday)
Restored from a different bootable backup I made after 2nd clean install and migrated applications.
Repaired Permissions using Disk Utility
Moved over Mail data
Copied over user data
*Didn't import the addresses
Checked to make sure all the fonts were validated and no duplicates
Everything worked fine after install and through Monday.
Problems to me (Tuesday morning)
Microsoft Office disappeared completely from the computer. No folder in Applications or dock icons.
Slower to connect to network files
Re-installed Microsoft Office to keep work progress going.
What would be causing this peculiarity? It works after I fix it and for a little afterwards but then strange things happen.
Would repairing disk permissions on bootable backup (of 10.6.8) before using migration assistant help?
What is the best way to track down what is causing these issues?
Thanks!

I suggest that the best way to upgrade from 10.6.8 to Mountain Lion is one of the following:
(1) Simply perform an upgrade install. This is in fact Apple's recommended approach. I am not sure why you have not yet tried that. I have done this myself successfully.
(2) Make a backup of the working 10.6.8 system; better yet is to make two complete backups, one being a "clone," the other being a Time Machine backup. Use of two different methods gives you options should something go wrong. Then erase the original disk and install Mountain Lion, and on the first boot up run Setup Assistant (which is better than Migration Assistant) and transfer over EVERYTHING, including user accounts, settings, applications. I have also used this approach, also successfully.
You did neither (1) nor (2), but seem to have done some sort of hybrid by transfering applications and then manually moving over some mail files and moving over some user files. I don't think this is a recommended approach. It can result in permissions issues, which can cause things to "disappear" or otherwise behavior oddly.
I do not understand how your use of a RAID setup and a RAID card might affect any procedures which otherwise might work smoothly. Are you 100% certain that your RAID hardware and firmware are compatible with Mountain Lion?
Assuming that the RAID is not the issue and it behaves to the OS just like a normal disk, I would try the full disk erase and install of Mountain Lion followed by a Setup Assistant on first boot up to move over everything from your clone backup.
If this does not work, then I would erase and restore back from your clone, so you get your 10.6.8 system working again. Then I would try a simple upgrade install of Mountain Lion.
If that fails, then I would erase and install Mountain Lion with one new administrative user created who has a different user name than the person whose stuff you need to restore. Then with that new administrative user I would make sure the RAID is all up and running. Then I would use Migration Assistant to migrate over users only and would reinstall all software from scratch. If that is not to your liking, I'd as a less desirable alternative use Migration Assistant to migrate over everything, applications and users. You will have that new, extra administrative user as well as the original user(s), but that should cause no harm.
