Is it possible to install lion on a partition of my iMac, and leave Leopard on the computer too.

I am curently running Leopard and would like to keep it on my iMac due to bits of installed software that I'd like to keep from becoming incompatible, but I'd also like to have OS X Lion on there too so that I can enjoy some of the benefits this has to offer. So my question is, am I able to partition my hard drive and install Lion on a separate partition, so that I can boot Leopard or Lion depending on which I need to use at the time?

Yes.

I have a iMac and i just updated the computer to Yosemite. I have Photoshop CS5 and when I try to print under print size --- manage custom size , photoshop unexpectedly quits every time. I updated the printer drivers (epson 9880) uninstalled and installed all the drivers. restarted computer and it is still doing the same thing. Cant find any costumer service here either except forums.

I have exactly the same problem - Whenever I go to Print, the print widow appears, it thinks about it for a bit (rotating symbol) and then quits.
This is the beginning of the problem details, cut and paste. It goes on much longer than this:

Is it possible to install Lion on the second hard disk on my Mini (2010) Snow Leopard Server, and switch between Lion and Snow Leopard? I like those voices Lion has in speech.

When baltwosaid NO emphatically, that was described as CORRECT ANSWER. Ditto in the caeses of the radically different answers from Camelotand Matt Clifton
Could it be that CORRECT ANSWER needs better defining by Apple?
That apart, yes, switching might involve rebooting. About the voices, well, I was the other day adding voice to a commentary in a video I was working on. There's only American English accent in SL — Lion I believe has British ones as well.
Why not, I wondered, try to install Lion purely for academic interest, maybe with an SD card (Sandisk Ultra II, 16GB) as Tom Nelson says is possible at http://macs.about.com/od/macoperatingsystems/ss/Perform-A-Clean-Install-Of-Os-X- Lion-On-Your-Mac.htm

Is it possible to install Lion Server over regular Lion?

I am considering buying Lion Server, so that I can get a feel for administering it (my background is in Windows Server and Warp Server for eBusiness). I have a 2010 21.5" iMac, which I upgraded to Lion a couple of weeks ago. I also have a MacBook Air with Lion.
I am wondering if I can just purchase Lion Server from the App Store and install it on my iMac, using the MBA as a client machine.
(1) Is this possible?
(2) Will I still be able to use the iMac as a regular machine, running (principally) Aperture and later on Final Cut Pro X as local programs
(3) What likely pitfalls am I going to encounter, and what (other than the client services) will I gain? I'm thinking that hosting Podcasts might be useful, but I don't know much about it
and finally,
(4) What resources are there to help me migrate my skills from Windows Server?
TIA,
Thomas

The other option is boot from your restore partition use diskutility to add third partition then use the reinstall lion option to install lion on 3rd partition, this will then download lion for you and reinstall it!
When this is done you can set it up properly (static ip etc) and then download the server app and install it!
Depending on what you want to do running it as your machine is not a big problem it works fine just keep in mind you might need to restart a few times and if you using it as a server that could be an issue!
in order to boot from your restore partition just reboot and hold down <alt>

When I used download sets of photos, movies etc, (before I installed Lion) I used always get a "Download" gizmo which showed me the download happening with both speed and time left. Now with Lion, nothing shows on my screen. Can I fix this?

In Firefox Options / Privacy be sure "Remember download history" is checked. To see all of the options on that panel, "Firefox will" must be set to "Use custom settings for history".

I am having trouble installing Lion on a partitioned hard drive. Help?

Aloha:
I am having trouble installing Lion on a partitioned hard drive
I have three internal HD's The first I am running the system on 10.6.8 (which is up to date) , the second I do most of my work on and the third I have partitioned into two and I am trying to install Lion on one of the patitions.
But Lion has decided it will only go on the first HD.
Above is the one I want to put it on, but it's not available and I can't change the partition scheme. None of the things the directions state are usable??
What might I be doing wrong?
Thanks
Dan Page

Thanks again for a rapid responce.
I finally got lion on one partition and my daily "SilverKeeper" backup on the other.
Since the only thing I had on the two partition Hard drive was the back up and since the backup would get put on tonight any way I changed the drive to no partitions. This gave me the ability to choose the GUID option, which I did and then I installed two partitions and successfuly istalled Lion on one of them. I even tied Lion into the iCloud successfuly.
But I am not out of the woods yet! I brought My brand new iPad to lunch and was informed that my iPad was synced to my Lion at home and I was on the cloud. That blew my mind, I was impressed.
I then read the Daily news with out problem, however, when I shut down my iPad, that was all she wrote. I can not get the iPad back on. The best I could do was see the revolving gear start and then freeze. It's on charge now and I can not even get rid of the frozen gear.
Not sure this all has anything to do with the recent installation on my main computer, but it's mighty suspicious.
Need some help!!
Thanks
Dan

How can I install Lion (10.7.5) on new iMacs 13,1

I have software and printers that will not work with Mountain Lion. Have partitioned and installed Lion on new partition using an older Mac as a slave and booting the new iMac as target disk. The Lion software installed, but now when booting Lion, partition just hangs with ghostbuster sign. Same with Lions recovery partition.
Why Apple any work arounds? Have not yet tried external drive with Lion installed. Any ideas appreciated.

New models that came with Mountain Lion pre-installed cannot run Lion. There is no known backward compatibility.
I suppose you could try running Lion in emulation using VM software like Parallels or VM Fusion.

Reinstalling OS X Without Erasing the 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.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Download and install the OS X Yosemite 10.10.3 Combo Update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet

Running Lion and Snow Leopard on the same MacBook Pro

So here's the thing .....apparently Lion won't run Photoshop and Illustrator CS2 (which I'm quite happy with and not about to shell out silly amounts of money to Adobe for even CS3) and apparently there may be (and I stress may be) problems with Word 2008 (likewise money to Microsoft for Word 2011).
I think, and probably won't know till I've installed it, that I'd like to try Lion on my Macbook Pro but keep Snow Leopard as a separate OS to run Photoshop, Illustrator and if necessary Word until I can afford to pay Adobe (& possibly Microsoft though I can't really see what improvements they can make to Word 2008) the large amounts of money they seem to think they deserve for an upgrade.
Does anybody out there know if it is possible to run both Lion and Snow Leopard on the same machine and if it is how do I do it?
Thanks for taking the time to read this.

Problem installing officejet pro 6830 software on my iMac running Snow Leopard

Greetings, I have a problem installing officejet pro 6830 software on my iMac running Snow Leopard. When I insert the HP software disc onto my iMac, and go to the HP website, it says:
"403" Ooops! Request forbidden...
Any possible solutions to this? Thanks for any feedback...

Hi @RNOjetnow ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue with needing the drivers for the 10.6 Snow Leopard OS. You should be able to install the Apple Drivers just by connecting the USB cable.
Here is a document that might help.
Hope this helps you install the drivers.
Thanks.

Reinstalling Mavericks depends on several factors:
if you erased your recovery partition
what OS originally came on your Mac.
I'll assume you don't have a backup available that you made before your mishap, because you didn't mention it.
That's really the take home message here: have a backup!
If you still have your recovery partition:
boot into the recovery partition (command R at restart)
use the recovery partition to reinstall Mavericks. see: OS X: About OS X Recovery
if you do not still have your recovery partition, then it depends on whether your Mac originally came with installer disks or not.
If it originally came with installer disks, you would boot from the installer disks, erase your HD, and then reinstall the OS that is on the installer disks, and then upgrade as necessary until you get to Mavericks.
If your mac did not originally come with installer disks, but you managed to erase your recovery partition, then you can try to boot into internet recovery (option-command-R at restart), and use internet recovery to erase your HD and reinstall the OS that originally came with your computer, and then upgrade to Mavericks if you need to. See: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld
(the reference refers to ML but it applies just as well to Mavericks).

Alternatively, partition your internal HD and dual-boot it. Do note that you have to reboot to switch back and forth. You can't do it by logging out and back in.

I have an iMac 5.1 which is running OSx10.5.8 - it runs very slowly and I can't find if there is a particular problem. In the process, I have tried to install 10.6 [I have a new iMac] and the 5.1 won't accept the install discs.
