Will upgrading from Lion to Mountain Lion delete my Windows partition (bootcamp)?

On my other computer I upgraded from Snow Leopard to Mountain Lion, and the windows vista partition was completely deleted. I was wondering if I upgrade from Lion to Mountain Lion on my other mac with Windows 7 will it be affected, or in other words, is Mountain Lion Bootcamp compatable with WIndows 7. Should I save it to an external hard drive?
Thanks!

No OS X installer deletes a Windows partition automatically. There is no reason for a Mountain Lion installer to do so when upgrading from Lion.
Nevertheless, having backups is always a good idea no matter what. If you don't have them, then this is a good time for them.

Will upgrading from MAC 10.6.8 to Mountain Lion, 10.8, cause any conflicts or problems?

I have MAC OS 10.6.8 and would like to use some applications that require me to upgrad to 10.8.--. Should I expect to experience any problems?

Check that your computer is compatible with Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.

You can also check which applications are PowerPC by going to the  menu, select About this Mac, click on More info…, then click System Report and select Software/Applications.
If you have applications that you want to use that aren’t compatible, you can retain Snow Leopard and create a new partition to install Mountain Lion on or you can run Snow Leopard server in a virtual mode.
Do a backup before installing.
Boot using the disks that came with your computer, the Snow Leopard DVD (if installed) or the Recovery volume (command -R) if upgrading from Lion. Use Disk Utility to Verify/Repair the disk and run Repair Permissions. Restart normally.
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable DVD/USB stick to install using this free program.

Will upgrading from Snow Leopard to Mountain Lion create problems within Premiere projects?

I'm looking at the probability of upgrading from Mac OSX 10.6 to 10.8 (Mountain Lion). I have to if I want to install or upgrade just about anything at this point.
I was hoping to wait until the latest Premiere project was finished to avoid creating possible discrepancies between how the project plays back before and after the upgrade. I'll skip the details and just say that it might be best if I do the upgrade now and install a new GPU to help with the massive amounts of rendering/playback needed. Will upgrading from Snow Leopard to Mountain Lion cause any likely problems? No other Adobe apps are involved with this project.
I'm running a Mac Pro 5,1 and Adobe CS6. I have two separate clone drives of my current boot disk as well as a Time Machine back up. So I can go back if I really need to. I'll also make sure the project is saved manually elsewhere.
Thanks for any input!

How can I upgrade from Lion OS X to Mountain Lion OS X

Hi my question is "How can I upgrade from Lion OS X to Mountain Lion OS X?"
I don't want to lose any data from my current Lion OS X, at the same time I don't have enough external HDD to backup. I tried to do the same was as http://www.apple.com/osx/how-to-upgrade/ says but I didn't get Mountain Lion OS X as an option for update.
Pleade advice,
Mustafa

Well, right. In 99.99% of cases you shouldn't lose any data.
But if something goes wrong, well, if you don't have a backup you're SOL.
You truly don't have ANY drive that you're using for Time Machine?
FYI: It's not a matter of IF, but WHEN, your hard drive will fail. It will eventually happen, so you should have a backup, unless you don't have any data you care about.

Does the Mountain Lion upgrade include the upgrades from Lion?

I was wondering if I should update to Mountain Lion, and I was wondering if it includes the upgrades from Lion as well?

You only need one OS. I'd use Mountain Lion, but you should first figure out if you have any old programs that are not compatible with either Mountain Lion or Lion.
Old PowerPC programs will not work on Lion or Mountain Lion.
To view which programs you have that are PowerPC, hold down option key and select System Profiler from the Apple menu. Then, select Applications in the Software section. Click on the Kind column header to sort by kind. Look for programs that are PowerPC. Those won't work. If you need them, don't upgrade.
Additionally, Roaring Apps has compatibility information for other software: http://roaringapps.com/apps:table

Will I be able to upgrade from Lion to Mavericks?

First, I know my machine will handle Mavericks, that's not my question. What I want to know is:
If I have Lion now, will I be able to upgrade from Lion to Mavericks for the Mavericks price quoted, or will I have to upgrade to Mt. Lion and then Mavericks? I was going to upgrade to Mt. Lion right about now, but don't want to pay for two upgrades within 3 or 4 months if I don't have to.

If everything goes like in Mountain Lion, you should be able to upgrade to Mavericks from any OS X version with the App Store: Snow Leopard, Lion and Mountain Lion, always that your MacBook Pro is supported, thing that we don't know yet until Apple releases the requirements. Note that this may change with the final version

Upgrading from Tiger to Mountain Lion

I have a friend asking me What are the precise steps for upgrading from Tiger to Mountain Lion for a MacBook Pro
I have the Snow Leopard disk.

They will need a minimum of a Core2Duo, the CoreDuo will not work, additionally they must have a 64bit EFI, machines that are compatible are ..... Macbook Pro (Mid/Late 2007 or newer)
If they have PPC programs (Office 2004, Quicken etc) they will not work on Mountain Lion and will need to be replaced, might want to check if they do.

Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

Upgrade from Snow Leopard to Mountain Lion erase my Windows partition?

Dear all,
I know some one might have asked it but I just wanna re-confirm.
Would the upgrade from Snow Leopard to Mountain Lion erase my Windows partition? I am currently using Bootcamp on my Macbook Pro (Late 2010 Version) and I do not have parallel desktop. I asked the same question when Lion was released, but HK Apple Store said YES and Melbourne Apple Store said no. I am a bit confused now.
Thank you for answering. Cheers!

Nothing.
That said, you should ALWAYS have a backup as anything can happen at anytime.

Windows 7 no longer boots after upgrade from Lion to Mountain Lion

I got a late 2011 MacBook Pro, on which I installed Windows 7 with Boot Camp. After I upgraded from Lion to Mountain Lion, I can no longer boot Windows. If I keep the option button pressed during boot I only get the OS X and recovery options, and if I choose to boot Windows from the system preferences pane, I get a message that says that no bootable device was found. However, I'm sure that the partition is still there, because I can see it in finder and browse the files normally. How can I boot Windows again?

"Easier" in this case as an alternative is defined as repartitioning/reformatting your disk, and restoring from backups (which for most people also means starting from scratch with Boot Camp Assistant and Windows since most users aren't backing that environment up).
What you did is, in my opinion, easier and faster. But if you don't know what you're doing can lead to data loss. But then, by definition, blowing away your disk and starting over with a restored backup begins with data loss!

While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?

While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?

Hello John!
Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
Well put and understood. What I should have said was:
1.Erase the volume
2.Install Mountain Lion clean
3.Confirm that Mountain Lion is functioning properly
4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
That makes sense and is just as I later suspected.
If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
Yes.
This is what I did and everything works perfectly. Thank you so much once again!

I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and somehow it crashes the mac side peridoically. I am told I need to "clean" it and reinstall lion using the recovery drive. will that delete the windows partition too??

I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and now the mac side crashes/freezes periodically, especially iphoto. I am told by the genius' that I probably need to "clean" it and reinstall lion using the "recovery drive" which resets everything back to default and reinstalls the lion operating system. My question is will this also delete the "windows" partition drive and all that data too. If so that will be a huge pain in the ___ to back up and reinstall boot camp and windows. I want to shoot the lion.

There is no system like Acronis for the Mac platform. You can try using the buiilt in Disk Utility to create an Image of the complete Mac drive but I have found that this does not work very well as on tryiing to restore it gives errors sometimes.
You can use SuperDuper or Carbon Copy Cloner to create a bootable Clone of your system partition. But that is only for the System partition and not the complete drive.
If you use Boot Camp to install Windows on your Mac neither of those two programs will clone the Windows side.
Neither will Disk utility as Mac's can not create or write to a NTFS partition. So some other program is need for that.

What are the benifits of upgrading from Lion to Mountain Lion?

I'm looking for the benifits of upgrading from Lion to Mountain Lion

You cannot upgrade to Mountain Lion anymore. Mavericks is now the current version. Got to Apple's website to see what the features of Mavericks are, then decide if upgrading is something you should do.
Upgrading to Mavericks
You can upgrade to Mavericks from Lion or directly from Snow Leopard. Mavericks can be downloaded from the Mac App Store for FREE.
Upgrading to Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Download Mavericks from the App Store. Sign in using your Apple ID. Mavericks is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
    Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?

Upgrade from 10.8 mountain lion–Should I or shouldn't I?

Greetings. I was ready to upgrade from 10.8 mountain lion to Yosemite but see all of the issues once upgraded that many have had. Now second guessing. Should I or shouldn't I? Is it worth it? I am a graphic designer and use for business as well as using all adobe products. I have a 27" iMac (late 2012) that is running os x 10.8.5 (12F45). Any insight very helpful. Thank you.

Why would upgrading from Lion to Mountain Lion more than double the size of my Time Machine backup?

I have a 500GB Time Capsule that has 248 GB used. After upgrading from Lion to Mountain Lion, Time Machine reported that there was no longer enough room on the TC to complete the backup. Surely the new system files aren't taking up over 200GB? Does it somehow want to copy all of my user files again, even though the vast majority of those haven't changed since the previous backup?
I'd like not to have to upgrade to a larger TC just because of a system upgrade.
Thanks in advance.

If it is working as expected, what do you need with the old backup?
If you want to be able to go back to where you were prior to an upgrade, isolate that backup and don't use it again. As far as Time Machine can tell, the whole drive changed.
The link I posted contains probably everything that anybody knows about Time Machine and how to manipulate it to work as you would like as opposed to how it was designed to work. There are FAQs to continue a backup as opposed to starting fresh, but I wouldn't recommend it for the reasons above. Pondini probably doesn't, either.
If you are going to do a wholesale upgrade of the OS, I would create a bootable clone using something like Carbon Copy Cloner or Super Duper. A bootable clone on an external drive can have you back up and running instantly if the upgrade fails in any way. If the upgrade goes fine, store it away in case you find the current system isn't to your liking.
