It is telling me to erase the disk than install but i cant loose data

it is telling me to do the erase and install and i cant do any thing else i dont no how to go back to the tiger os to get the data do i cancel the instal and press startup disk???

Cancel the install and reboot. Don't do any sort of install because you'll lose all your data in the HD reformat. If you cancel though, your old system should be unaffected.
FWIW, I had the same problem you have. I wanted to try out Leopard still, so I installed it on an old firewire ipod -- at this point, I'm glad I was unable to upgrade. Stacks are lame, you can no longer drop a folder on the end of the dock and then use it like a menu -- stacks are one level deep only. Secondly but more importantly, X11 is totally borked in Leopard. This won't apply to people who don't use X11, but for me, working X11 is a pre-requisite.
Consider yourself lucky you can't upgrade.

HT201372 Failed to start erase of disk due to error (-9999, 0). A error occurred erasing the disk.

Tried the recommendations in this article, however ran into the error posted below.
Creating a bootable OS X installer in OS X Mavericks
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath "/Applications/Install OS X Mavericks.app"
Ready to start.
To continue we need to erase the disk at /Volumes/Untitled.
If you wish to continue type (Y) then press return: Y

Is there an updated document ?
MacBook 13" white - Early 2009 model

Oh, createinstallmedia only runs on OS 10.9! Oh! The 9999 is if you try to run it on an earlier OS! Oh! Linc means to update the current drive to Mavericks, and then one will be able to run createinstallmedia, if one has first saved away a copy of the installer.
But if, like me, you are trying to create an installer to do a clean install on an empty drive, without replacing the earlier OS on your current drive, then...
You must use the slightly more complicated instructions you can find all over the place that look like
Right click "Install OS X Mavericks.app" and show package contents
Find a certain .dmg file and double click
Find a hidden .dmg within the drive that mounts from the first .dmg
Double-click or use "mount" on the hidden .dmg within the .dmg
Use Disk Utility to "restore" the second disk image onto the erased USB drive
Then replace an alias folder with a copy of a huge folder within the first disk image
I had success with the "Option 2: Use Disk Utility" section here.

HT5287 I am trying to install Office:Mac 2011 on my Air using a remote disc. I have gotten all the way to where I am installing it on my air, but it is telling me to select a disk to install office on and there is nothing to select. The box is empty.

It might be easier to download the trial version from the microsoft site and then use the code off your box set to activate it.

When Updatind any OS for iMac, is it better to do it by "Update Software" or erasing the disk?

I had this wondering when Mountain Lion came Out, now that OS X Mavericks it's coming soon I'm not quit sure what kind of process is better for my iMac. The Fact is that my iMac is getting a little bit slow (since iTunes updates began to come out last year) and I dont know if when I do the software update it would get faster or would still have the same speed problems.... So I thought it may be good to erase the disk before updating...
Help Plz!

You might troubleshoot that issue now...
Make sure you have neough free disk space. Rule of thumb about 10% free minimum.
What happens you login into another user, like Guest. Or better yet, try starting in Safe Mode and see if the slowness still occurs?
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first.)

How to re-install iWork after erasing the disk?

I had to erase the disk, now after I have installed Maverick I see that I've lost iWork and iPhoto. How can I re-install them without having to pay again?

Check the Mac App Store.
Anything you ever purchased (including Mavericks, "purchased" for $0) should appear on your Purchases tab, ready to re-download at any time.

HT4906 Erase the disk for more space but ilife software are all missing!!!

Hey, I just erase the disk for more space, when I reinstall mountain lion, the I life software are all missing! And in app store it shows up that I need to buy them! So ridiculous !!! Why I can use them before

What's ridiculous? You erased the apps. They're not part of the OS. So, reinstall them for wherever their original source was.

Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and

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.
    OS X Mavericks- System Requirements
    Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later

I just bought a Intenso hard drive and its asking me to erase it before using time machine. should i erase the disk?

Hi all.
I just bought a T1B Intenso Hard Drive.
Plugged into my MacBook Pro and TimeMachine instantly pops up asking me if i want to back up.
I do, so I accept and encrypt it.
However, a message appears and asks me if I want to erase the disk (nothing is on there) to be able to continue.
Should I erase the disk?
Will it corrupt the files saved on it?
Thanks all.
±Adam±

Have you already formatted the drive using Disk Utility? If you erase the drive then, yes, you will lose all data on the drive.
If you want to use the drive as a Time Machine volume, however, you MUST format the drive as "Mac OS Extended (Journaled)" using Disk Utility (Applications>Utilities folder).
Good luck,

I have a 15" MacBook Pro 2.4 GHz Intel Core 2 Duo (Early 2008) running OSX Lion 10.7.5. I want to erase the Hard Drive, install Mountain Lion, and manually restore select applications and files. Is there a known procedure to do this? Any tips or feedback?

1. Make a backup, open App Store and purchase Mountain Lion. When its download finishes, close the installer and open Lion Diskmaker to create a bootable USB drive with Mountain Lion.
2. Press Option key while your Mac is starting, select the external drive and open Disk Utility.
3. Select Macintosh HD in the sidebar and erase the drive.
4. Close the window and install Mountain Lion

After downloading Yosemite Installation got stuck as the disk needs repair but is not available.

Now I can't access my Time machine and it has not backed up since 3 months. I am stuck as i don't know how to get back to my old OS and basically ignore the Yosemite download until I figure out what is wrong with my SSD. I successfully replaced the HDD several months ago with a Crucial 240GB SSD and had no issues at all while working on it. However, now I seem to be completely stuck: can't get back to 10.9, can't back up to my Time Machine, can't even erase the disk and lose 3 months of data because of some disc mounting issue. What a mess I have created. Please help.

Ok everyone,
I may have a solution. I too installed Yosemite only to be stuck with nowhere to go because I couldn't repair my disk in the Disk Utility. I would verify over and over and sometimes I could click repair and sometimes it was grayed out. I would get red messages saying you can't unmout the disk, you can't repair it, etc. So, I read on another forum some chick used her CD of snow leopard and reinstalled that OS versus trying to install Mavericks again (which I tried too, but the disk was locked because it wasn't repaired). So I popped in the CD, restarted my computer and pulled up disk utility again. The first time I ran the repair function I actually got a kernel message (which is bad) and had to restart again. The second time, however, I ran the repair and it fixed it! I got a nice green message saying the disk had no issues appeared to be ok. So, I went to reinstall snow leopard and my Macintosh disk was no longer locked because it was repaired! I just installed it and I'm waiting for my computer to reboot so cross your fingers that this works.
I feel like this is good news because it makes me think that I don't actually have a hard drive issue but rather Yosemite was corrupted. I take very good care of my iMac so it would be heartbreaking if I had to put money into it when I've never had issues with my apple products In the past. Hope this helps anyone in the struggle. I'm not smart enough to hook up external hard drives and run programs or type code into the terminal. So consider this the simple man's resolution (I'm a woman). Feel free to ask me any questions, I'll check back when I can.

Help

The two other posts are correct... so I'll just clarify. What's happening right now is your system is trying to boot into Windows in order to finish the installation. What you want to do is make it boot into OS X. As mende1 indicated, with your system off, hold down the Option key and continue to hold it while you turn the system on. You will eventually be presented with an option to select which partition you would like to boot from. Choose OS X. After you get into OS X, again, as mende1 indicated, change the Startup Disk to OS X. What this will do is cause your system to automatically boot into OS X when you restart it instead of you having to use the Option key when booting each time.
Relaunching BootCamp Assistant will allow you to remove your Windows installation and partition.

My MacBook Air lost mac os x. So I would like to reinstall mac os. But I can't select the disk to install mac os x. Only Recovery HD is shown and I can't select it. How can I reinstall my Mac os x.

My MacBook Air lost mac os x. So I would like to reinstall mac os. But I can't select the disk to install mac os x. Only Recovery HD is shown and I can't select it. How can I reinstall my Mac os x? Thank you!

you can download the mac os x recovery hd and run the setup to a flash drive using another mac computer running os x 10.7,(so that while installation the os x setup can varify your computer's serial no. and provide you the installation setup through internet)
or the time machine backup(if you have)
Now boot through the flash drive and follow the steps to install mac os x
here is the link to download the recovery hd for flash drive

I recently brought a HD PVR, i put in the disk to install the hard drive and it said " This program doesn't support DOS Mode! how do i get out of DOS Mode?? Please Help

What exactly are you trying to do? PVRs are for recording from TV not computers.
Either way, if it's complaining about DOS mode, it's Windows oriented software and not Mac compatible.

It is telling me to erase the disk than install but i cant loose data
