HT1329 i have re-installed I-tunes and have a new operating system (Win 7 Pro). I now cannot sync as I-tunes says my I-Pod is already connected to a library and wants to erase my music on the I-Pod. What do i do to get around this problem?

An iPod is designed to be synced with only one computer/iTunes library at a time. If you try to sync the iPod with a new/different iTunes library, iTunes on the new/different computer will replace the contents currently on the iPod with whatever is currently stored in its own library.
If the music and content on your iPod is not in iTunes or in a backup somewhere you can use the information in this user tip from another forum member turingtest2 to help you copy this content from the Nano back to the PC and into iTunes.

Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

I have an original iPad and downloaded the new operating system. Now' I cannot write on my Contacts or Calendar apps, and my Pages app (purchased) has lost the ability to use the bold, underline, and italics functions. Does anyone know how to fix these

I have an original iPad and downloaded the new operating system. Now, I cannot add to my contacts or calendar apps, and Pages ( which I purchased) is not allowing me to use the bold, underline, and italics functions. Does anyone know how to solve this problem?

No, it stays with the current OS (iOS5 in this case) - Apple doesn't allow downgrading iOS
If you are syncing to a desktop, you shoudln't lose anything. If you aren't syncing, then that's the first thing you should do, to protect contacts etc.
the other thing is, when the iPad is connected to iTunes, right-click its name in the Devices list and choose Back Up.
That way, when yoiu do the restore, everything should come back as was.

Can I install a new operating system using a USB optical drive?

My Mac is out of date, I'm still running 10.5.8 but have the Snow Leopard disk to update my operating system to 10.6.3. However, my built-in optical drive is broken so I use a USB powered optical drive. So, when I start the process of installing the new operating software, will the MAC direct itself to my USB drive to boot when necessary?

Thanks for the replies. Just to clarify, because I'm on 10.5.8 I have to upgrade to Snow Leopard using a dvd disk, which I have. I cannot upgrade to any other more recent operating system until I'm on Snow Leopard, so that's the first thing to do.
So, just to clarify further, I have a DVD drive that plugs into 2 USB ports that I use to burn and read DVDs, ever since the inbuilt DVD drive on my iMac started sticking disks inside.
So...I'm really looking for the best way to do this upgrade with what I have...I don't know whether the Mac will find the disk if it is on the plugged in portable DVD drive rather than the inbuilt DVD drive....
Any advice greatly appreciated...

MY ITUNES SHUT AS IT WAS INSTALLING A NEW OPERATING SYSTEM

as i was installing the new IOS 4.3.10 on my iphone, my itunes randomly shut its self down and now my iphone is stuck with out an operating system WHAT DO I DO?

More likely the problem is that you are trying to install 4.3.10 on a CDMA phone (assuming your category is correct). The latest version for the CDMA phone is 4.2.8. Normally iTunes won't even let you start installing the wrong version, so you are probably doing it by an unauthorized method.

I lost all my Bookmorks after installing a new operating system.

I have just obtained a new PC and installed Windows 7 Ultimate in 64 Bit. And as is usual for me DESPITE backing up etc the whole shebang blew up in my face! the back up failed and I had to re-install again! So question is I have the OLD operating system on the OLD HD so I can find things. So how do I find the old bookmarks etc. and move same to my NEW HD and so enjoy my old settings? Indeed is it possible to install AL of the old settings from the older copy of Firefox on my old drive? If so and it is a relatively easy thing to do please feel free to ridicule me but do at least offer to help? :-)
Regards
chris

No, that file won't help you.
Look for your Firefox Profile folder on the old HDD, and copy specific files from the old Profile folder and replace the new version of each file in the new Profile folder. This support article will explain it more completely. <br />

Will installing a new operating system make the warranty void

I just bought a HP G3 200 Series 250 Core i3 from Indian online store. The current operating system is free DOS and i want to install windows 8 on it. Will that make my warranty void ?

Hi: Doing that will not void the hardware warranty but HP will not offer any software support if you install another operating system. Bear in mind that there are no W8 64 bit drivers for that model, so I suggest you upgrade to W8.1 after you install W8 or install W7 64 bit.

I had to install a new operating system and now my music is gone from iTunes

My MacBook Pro crashed the other day and I had to reinstall Yosemite. Now when I go to iTunes library most of my music is missing. I have a lot of it on my iPhone but it won't transfer back to my computer. How do I retrieve thousands of songs?

Use your Time Machine backup if you have one.
Your can also recover your iTunes Store Purchases from the iTunes Store in the "Purchased" Tab on the right.
You can't get your music from the iPhone to the Mac, unless you use 3rd party software.

I have OS X Version 10.5.8...how do i install the new operating system?

I have OS X Version 10.5.8 and I am trying to download the newer version of i-tunes however it says that I need a new version of the os but I cannot figure out how to update my OS? Please help!

The first step in Upgrading... is to Snow Leopard = OS X 10.6.x
It is Not available as a download... It is a Paid Upgrade.
Do this first...
Check that your Mac meets the System Requirements for Snow Leopard...
Snow Leopard Tech Specs
http://support.apple.com/kb/SP575
If so... Purchase a Snow Leopard Install Disc...
http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
Other countries...

After the Successful Install, run Software Update to get the latest updates for Snow Leopard and iTunes.
Be sure to make a Backup of your Current System Before Upgrading...

I recently installed the new operating system. iMovie doesn't seem to work the same as in Mountain Lion. I can't figure out how to burn a movie to a DVD. Has that feature been eliminated?

I am having difficulty figuring out how to burn my iMovie to a DVD. Has that feature been eliminated?

unbelievable... the amount of RAM is the issue... I found a post (http://forums.creative.com/creativelabs/board/message?board.id=soundblaster&message.id=8448) on an unrelated matter, but the user solved their issue under X64 by limiting the amount of RAM WinXP x64 was using by editing the boot.ini file.
The basis of the "trick" is to add " /maxmem=4096" to the end of your OS line, but I elected to copy the line and add it to a new entry so I could easily select which "mode" i wanted at boot.... like so...
multi(0)disk(0)rdisk(0)partition()\WINDOWS="Window s XP Professional x64 Edition" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition()\WINDOWS="Window s XP Professional x64 Edition - X-Fi tweak" /noexecute=optin /fastdetect /maxmem=4096
amazingly this solved my issue... but now my system properties only report 2Gb instead of 4Gb... unacceptable!
When Can I expect a fix for this Creative?

After installing new operating system, I can't connect to internet from an e-mail. What is wrong?

After installing the new operating system, I can't access the internet from an e-mail request. What' wrong?

Finally gave in and called Apple Support.
1) They had me restart while holding down the Option-Command-P-R keys (this resets the HW apparently. Didn't fix it.
2) Next they had me move my System Preferences folder to the trash. Still didn't fix it.
3) Lastly they had me move all my cache files to the trash and then empty the trash. Restarted and it seems to be fixed now.
I was told that sometimes after an upgrade if you don't "delete all your caches" that there can be problems. I'll have to see if the connection holds up since before the problem was intermittent, but at least now I have a case number and all seems well so far.
I encourage those who are experiencing issues to please call Apple Support - it appears that there is no one fix and it depends on so many different factors. If this issue re-appears I'll be back on the phone with them - plus I'll update this thread.
Thanks!

Installed new operating system

I just installed a new operating system and had to re-install itunes. it counted that as one of my "uses" of my music library. how do i reset that so that I am able to use my new ipod?

Hello, Annie, and welcome to the Discussions.
Sorry, but what do you mean by "reset"? You shouldn't have to do anything special, as long as you have your content in iTunes. Just attach your iPod and it should offer to sync to the iTunes library automatically.
You may need to describe more fully what it is you're trying to accomplish.
Regards.
