I am trying to re-install mountain lion on a new hard drive on a mac pro but get a backward slash with a circle

I am trying to reinstall mountain lion in a mac pro with a new ssd drive but will not let me. It gives me a back slash with a circle. I have 2 optical drives, first is a blu-ray and the second is a super drive. could that be the cause?

Firstly, you need to partition and format the SSD. You need to be able to boot the computer from another drive that has a bootable OS X system installed or a Snow Leopard DVD installer that works on the computer.
Install Lion/Mountain Lion on a New HDD/SDD
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 Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external hard 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.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

How do I re-install Mountain Lion on a new hard drive (replacement)?

I have an older iMac 24" (2007) that has been up-graded to Mountain lion. I want to replace my hard drive with a bigger one (has 500Gb). How can I re-install Mountain Lion on my new drive? I have Time Machine on this machine.

Install 10.6 and 10.8 onto the new drive exactly how you did it on the old drive, except that you won't need to pay to redownload 10.8. Alternatively, if you kept a copy of the 10.8 installer, you can just rerun it.

Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the 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 leftside list. 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.
Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this entire command line after the prompt in the Terminal's window:
     sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume
     /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.

How do I install Mountain Lion on a new hard drive

Bit of a novice here.
13inch MacBook Pro mid 2009 unibody user. Upgraded to Mountain Lion via download. I need to upgrade my HD for more space. No longer have the install CDs that came with it.
How do I go about installing the OS on the new HD?
Many thanks.

As an additional thought:
You may want to consider contacting Apple for replacement install disks anyway for whatever OS it came with because:
Your license for Mountain Lion purchased at MAS is not transferable - it is forever tied to your Apple ID (and the machine ID). If you sell/gift your Mac, you will need to erase the Mountain Lion and reinstall the original OS; otherwise the buyer will have an illegal copy and will not be able to reinstall (because the Apple ID is not the same as it was when purchased).

How do i intall mountain lion on a new hard drive

How do i do it?
I bought a new 13" MBP a few weeks back and have now got my SSD. I realise that Apple no longer give out OS install discs and i don't have mountain lion purchased on my app store as it came with my laptop. So how do i install mountain lion on my new hard drive without having to buy mountain lion.

Option 1 - Newer Mac's like your come with internet recovery. Which means if your drive fails or is corrupted or in your case your install a brand new drive, internet recovery will let you reinstall the OS you are eligible for. So replace your drive and boot your system with cmd + R keys pressed down for 15 secs or so and your machine hooked to the internet. This will install ML from apple in your case.
Option 2 - Clone or backup (your entire system using time machine) your hard drive to a external USB disk. Replace your drive and then restore the new drive from the clone or backup.

After installing Mountain Lion doesn't external hard drives mount or stay mounted. Anybody else with this major problem?

After installing Mountain Lion doesn't external hard drives mount or stay mounted.
I have tried resetting my Mac's PRAM but the problem still remains.
Even USB memory sticks are unmounted efter a few seconds.
Anybody else with this major problem?

I have the same problem, although mine has not been solved by ESET update, finder settings, PRAM & SMC resets or anything else.
Don't get it, my external hard drive still works on both my housemates computers - one macbook pro (with snow leopard) and one dell, just not on mine with mountain lion.
Any ideas for me guys?

Can I install Mountain Lion on a different hard drive when it's already installed on one hard drive?

I have a Mac Pro with two 2TB hard drives installed, one I use for storage, and one as my startup disk (also store things on there as well). I just installed two new 2TB drives and have set up a RAID 0 with them. I want to use the RAID drive as my start up disk, but I'm not sure if I can install Mountain Lion on the new RAID drive while it is still on the original start up drive. I also don't want to lose or erase any information from my current start up drive. Can anyone offer me guidance??

Firstly, you need to partition and format the SSD. You need to be able to boot the computer from another drive that has a bootable OS X system installed or a Snow Leopard DVD installer that works on the computer.

Installing Mountain Lion onto an external hard Drive

Hi
I am running snow Leoprd and what to keep this as my main OS on my internal HD due to work, I want to install Mountain Lion onto an external Hard Drive and boot and run from an external HD as opposed to my internal
I will be likely to be using a thunderbolt connection for the external HD
Has anyone had any experience with this and any tip or faults?
I will be using Logic mainly]

Works just like installing on an internal drive. Just be sure to choose the correct target before clicking on the Install button.
If you have sufficient space on your internal hard drive you could also make a partition on it in which to install Mountain Lion. This will be faster and more convenient that an external drive.

How do I install Mountain Lion AND format the hard drive?

I want to do a completely clean install of Mountain Lion.
I had Snow Leopard installed, upgraded to Mountain Lion (by buying it from the App Store) but how do I tell it to format the drive and then install Mountain Lion?

Snow Leopard would have needed to be installed on a properly formatted drive, so I don't understand why you would need to format it again to that same format.

Why am I not able to install snow leopard on a new hard drive for my macbook pro, which at one point was upgraded to Lion?

I've just had my hard drive go caput and after purchasing a new one was inclined to install snow leopard but received an error message when attempting to do so.
I did not create a back up or restore file before I decided to upgrade from snow leopard.
I'm wondering why am I not able to simply install snow leopard on a brand new hard drive. What would clue it into me having had ran lion before and why can't I simply delete that kernel or said file. It makes completely no sense to me. I come from a pc world where if I choose to format a hard drive, I can do a clean install of whatever OS I choose. After all I only paid for my laptop as should be able to do with it what I wish.
Any suggestions or insight would be greatly appreciated

1. Was Lion on the machine and trying to downgrade?
2. If so this might be an issue. Newer machines are done for current OSX.
3. If you have Lion on your machine try to install Snow Leopard on another partition or portable HD
4. After you format and install SL on the other partition or drive Try to boot from this machine retarting and holding the Option key at boot up.
5. See if that work.
This is a trial and error way but Mountain Lion is right around the corner and Snow Leopard is 2+ yrs old.

Re-installing OSX Lion on a new hard drive

I'm thinking about replacing my 320 GB hard drive. I just bought my mac a couple of weeks ago. I noticed that Apple recently upgraded their line of macbook pro computers. Since I want to replace my hard drive with a new one. I was wondering if I really need to clone an external hard drive in order to reinstall osx lion again? Should I follow this procedure that I saw on apple's web site?
http://support.apple.com/kb/HT4718

No, you don't need to do that. Just literally clone the old drive to the new one using Carbon Copy Cloner (CCC), Super Duper or the Mac's Disk Utility. Best way to do that IMHO is to put the new drive into an external enclosure, preferably FireWire since it's a lot faster than USB, do the clone to the external, reboot to the external to make sure it's working correctly, and then swap the internal and external. Not only is this faster, it leaves you with a bootable clone (your old internal drive) in case of emergency.
Replacing the hard drive in a MacBook Pro is pretty straightforward. You'll just need the right size Phillips and Torx screwdrivers.

How long does it take to reinstall Mountain Lion on a new hard drive?

Due to performance/corruption issues, I erased my MacBook pro's hard drive. Now, I'm attempting to reinstall Mountain Lion (then do the upgrade to Mavericks). However, after about 5 hours of it doing the reinstall and downloading files (I have it connected to a network cable), I went to bed.
At some point during the night, the process seems to have timed out. Evidently, I will need to start from the beginning of the installation process.
My Questions:
How long should I take?
Is there a way I can prevent the MacBook from going into sleep mode so I can leave it unattended?
Since I've worked in corporate IT, I'm more than familiar with the Windows reinstall process and generally know what's going on and how long portions of an installation should take. Is there a way I can have the installation tell me what's going on?
Any other tips/tricks or general information?
Thank you for any assistance.

Wish I had your DSL speed. iTunes suggests I have about 7 1/2 hours still to go! Just glad it is giving it it's best shot.
Thanks for your reply.

How do I reinstall Lion if I get a new hard drive? My mac came with Leopard and I cannot find my upgrade disk for Snow Leopard

My MacBook Pro originally came with Leopard. I have the OS and Applications disks for Leopard but I cannot find my upgrade disk for Snow Leopard. I would like to perform a clean install of Lion on the new hard drive and restore some data from my Time Machine backup. I am not looking to restore the current image to my new hard drive. I have not yet removed the exisiting hard drive nor have I wiped my data.

The only way to do that is to buy a New SL Retail DVD. Or you could buy the Lion Install USB thumb drive from Apple for $69.
You must have SL installed to then install Lion or have a thumb drive with the Lion installer.
You could also create a Lion USB Recovery thumb drive using Lion Disk Assistant. But you need to have Lion already installed and the Lion RecoveryHD Partition on your drive to make the Recovery thumb drive.

How can I re-install CS2 upgrade on a new hard drive without serial no. of previous Photoshop 5?

A new hard drive has been installed on my G4 Mac with OS10.4. I am trying to re-install CS2 Premium on the new hard drive but I no longer have the serial number of my previous Photoshop 5. I need to enter this as the CS2 was an upgrade. I have spoken to Adobe technical support but they no longer support CS2 so are not able to help. They recommended that I try the Adbe Forum. All my Adobe products have been bought legitimately. I know people manage to use pirated Adobe software so there must be some way for me to activate a legally bought product.

Michael
Thank you for your email and suggestion.
I have tried that and the only product listed is my CS5 Design Premium (which was an upgrade), none of my previous Adobe products are listed.
I am now looking to see if I can buy an old version of Photoshop that will work on a Power PC G4 Mac with OS 10.4.
I only need Photoshop on that Mac to paint from, not the rest of the Suite.
It is infuriating that I already have a legitimately bought Adobe product (as all mine have been) but I am unable to use it.
Regards
Trevor

Trouble installing 10.4 on a new hard drive

My hard drive died, so I'm trying to install 10.4 on a new hard drive. I'm using the same disk that came with my laptop. I get as far as "select a destination" and the hard drive doesn't show up to choose. I saw another post that suggested partitioning the hard drive first, so I did that, and still no luck. Can anyone help?

Thanks for the welcome, and for the attempt to help. I'm starting to wonder if I got a bum replacement hard drive? I've just restarted twice, it now takes FOREVER for the apple and the little spinny thing to show up when I start up and hold down the C key, and now when I go to disk utility the hard drive doesn't show up in the list of choices at all. Do you think it's worth pulling out the hard drive and sticking it back in again? I have no idea if that will make any difference?
