Can I install Mac OS X Lion on an external FireWire800 drive?

Can I install Mac OS X Lion on an external FireWire drive? I have bought a Lion Thumb Drive. I'd like to install Lion on the FW drive and then boot from there. The FW drive is a brand-new LaCie D2 Quadra 2 TB drive that has FW 800, 400, USB, and esATA connectivity. Can't find any manual describing how to do this. Any help appreciated. The more detail, the better. Thanks.

Yes, you can. When you run the installer you will get to a screen where you will see the default target drive, usually "Macintosh HD." Under the icon you will see a link to display other drives. Click on that so you will see the external drive you have connected. Select that then continue the installation.
For simplicity connect the drive using FW800.

Mountain Lion doesn't ship on any media and is too large to fit on a CD.
You must purchase it using the App Store and it downloads over the Internet.

How can you install Mac OS X Lion on a new, empty hard drive?

If the only way to install Mac OS X Lion is by downloading it via the Mac App Store, it's going to be very difficult to put it on a brand-new hard drive unless Apple provides us with workarounds,So what should we do when want to install Mac OSX Lion on new HD?
ThanQ

What you get from the Mac App Store will be an Installer Application. You will be able to transfer that Installer from Mac to Mac. I have not seen it yet, but we may also be able to burn an installer disk, we shall have to see just how things work.
Apple has always been known as an innovative company. And when they announce something new folks always go nuts with reasons that this cannot work. When Apple stopped making Macs with floppy drives and iMacs only had optical drives, people went crazy. Today no one makes computers with floppy drives.

Create a Backup Lion Bootable 10.7 Disk
Purchaseand download Lion from the Mac App Store on any Lion compatible Macrunning Snow Leopard.
Right click on “Mac OS X Lion”     installer and choose the option to “Show Package Contents.”
Inside the Contents folder that     appears you will find a SharedSupport folder and inside the     SharedSupport folder you will find the “InstallESD.dmg.” This is     the Lion boot disc image we have all been waiting for.
Copy “InstallESD.dmg” to     another folder like the Desktop.
Launch Disk Utility and click the     burn button.
Select the copied “InstallESD.dmg” as the image to burn,     insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot     Disc to come out toasty hot.
With this disc you can boot any Lion compatible Mac, and install10.7 just like you installed previous version of Mac OS X. You caneven use Disk Utility's Restore function to image your Lion boot discimage onto a external drive suitable for performing a clean installon a optical-drive-less MacBook Air, or Mac mini server.
If your using Mac's in a mission critical type environment or have third party hardware or software you must rely upon working correctly. It's advised to wait until all the bugs, driver updates, third party software updates and other issues are resolved before upgrading. This might take several months. Then if you do so, do one machine at a time and carefully test everything before full deployment.
It's also highly advised to backup all one's data either manually to a external powered drive in addition to TimeMachine and Hold option bootable Carbon Copy Clones etc.

I can't install Mac OS X Lion, I want to go back to Snow Leopard

The problem is I am stuck in the OS X Lion Install window but when I try to install it, it asks for my Apple ID, I give it but It says I haven't bought Lion. So I gave up and decided to just go back to Snow Leopard, how do I do that?

Welcome to the Apple Support Communities
Have you purchased OS X Lion? If so, check that it's not hidden in your Apple ID, so unhide it > http://support.apple.com/kb/HT4928?viewlocale=en_US&locale=en_US Finally, you will be able to reinstall Lion.
If you want to go back to Snow Leopard, your Mac should have come with DVDs or a USB drive. If your computer came with a USB drive, just insert the USB drive, hold the Option (Alt) key while your computer is starting, choose the USB drive and reinstall Snow Leopard. You may have to erase the hard drive before installing it.
If your Mac came with DVDs, you need an external optical drive or another PC or Mac to use Remote Install Mac OS X

When I go to install Mac OS X, it says that the computer cannot start-up from this disk. With Mac OS 9 it would. I don't have any other Mac OS CD-ROMs, and I reformated the Hard Drive to see if that would fix it. no luck. I need this fixed!

Installing Mac OS X Tiger on an external hard drive

I was wondering how to install Mac OS X 10.4 Tiger on an external hard drive. I have a 40GB USB/Firewire LaCie Mobile Hard Drive.
I've tried using disk utility to convert it to Mac OS Extended (Journaled), but when I attempt install Mac OS Tiger from the system disc after restarting the computer, it shows the available disks that Tiger can be installed on and the ones it can't be installed on, and my external drive shows up as one that it can't be installed on for some reason.
I don't really want to clone my internal hard drive to the external one, but instead want to just be able to use my external hard drive as a mobile startup disk where I can work on files using other Mac computers when I'm away from home.
Any suggestions?

What did you do in DU? Erase? Partition? and what was it before? or just to enable journaling? What is on the LaCie now and does it have adequate space?
Do you have an upgrade Tiger disk?
And why not just clone the system using CCC and skipping /Users and other directories you want to skip?
One last thing: click on the volume and do a Get Info and make sure that Ignore Ownership is not selected.

Can I install OS X Mavericks directky to an external hard drive?

I still need to run and use OS X Snow Leopard.
I like a lot of the features of OS X Mavericks and updated apps for OS X Mavericks and would like to install this OS onto my FW800 external hard drive directly.
Can this be done?

Also, if you have enough space on your internal drive, you can add a partition and add Mavericks to it.

Can't Install Mac OS X Lion On Used MacBook

Hello I finally decided to buy my first Apple product and it was a used MacBook. The previous owner had erased the hard drive or whatever so I can only access the Mac OS X Utilities. I went to reinstall the OS using the Reinstall Mac OS X option where I found that I needed to make an apple id, after doing all of that I kept getting a prompt saying "This apple ID has not purchased OS X Lion". So I bought the OS X Lion on their website and finally got the redemption code in my email but it says I have to redeem it through the Mac App Store which the MacBook I bought does not have. I also do not own another Apple product or know of anyone with a Mac I can use to redeem the code with. Also the closest Apple Store is like 3 hours away from me which I don't have any free time to spare driving there. Also I do not have any of the install discs that would of originally come with it. If anyone can help me figure out how to redeem this it or just let me know if it is a lost cause, it would be greatly appreciated.

Not sure what exactly you wanted but this is what it gave me

Can't install Mac OS X Lion

I recently installed a new Hard drive into my MBP. The install for the OS worked for about a week, then began to freeze. I was forced to manually shut down the Macbook (Holding the power button). I figured it was an OS problem, so I decided to wipe the HD again using the Disk Utitlity off the OS Disc. I tried to install the OS and halfway through the installation of the OS I got an error message saying "Install Failed, Mac OSX Could not be installed on your computer, click restart to restart your computer and try installing again" Now when I press restart, the same thing occurs. I try manually shutting down and booting from the disc, to partion the HD again, but it doesn't boot, it goes straight to the installation. How do I get rid of this to get my Mac up and running 100% again? Here's a photo of what I get through the installation. Its not the best quality but its the best my 11" Acer can get lol. Hope it helps!

Back up all data. Boot into Recovery (command-R at startup) and erase the startup volume in Disk Utility. Then reinstall OS X and restore your data in Setup Assistant.

I need to re-install mac os x lion

Hello,
I installed windows 7 on my imac but when I made it, I remove all other parts including mac os x boot section. I can not find all drivers for windows 7, because of that I want to re-install mac os x lion but I don't have any installation DVD, also I don't have any installation file on my HDD. How can I install mac os x lion again?
Thank you.

I'm hoping you didn't totally wipe your system, try booting and when you hear the Startup Tone hold down the Option key and choose the Recovery Partition and then install Lion. If you totally erased the drive and the only thing left you will have to try using Lion Recovery & Lion Recovery, OS X Lion: About. If those don't work then your next stop is an Apple Store or AASP for service.

How do I boot Mac OS X Leopard from an external hard drive onto an eMac?

My eMac's internal hard drive died a while ago, and I was finally able to successfully able to install Mac OS X Leopard onto an external hard drive. However, my eMac still refuses to boot Leopard. I only keep being put on the OS Install/Upgrade screen. After install, I selected the Start-up Disk utility and chose my hard drive. Upon restart I find myself on the Install/Upgrade screen as I said earlier. I tried restarting again, but this time I pressed the option key to select a boot disk. However, only my Mac Install Disk shows up.

How is the external HD connected - USB or Firewire? Most Power PC Macs can't boot from a USB connected external HD.

When I try to install Lion it tell's me "You can't use this version of the application install mac os x Lion with this version of Mac os x" even though I have the latest update 10.5.8 of Mac os X?

The install icon has this sign on it

You can't install Lion over Leopard. To install Lion, a requirement is Snow Leopard. So you can either upgrade to Snow Leopard first or you can make a bootable Lion install disc and use that to wipe your hard drive and install a fresh copy of Lion.
So to make a disk would require you to purchase Snow Leopard and upgrade to 10.6.8 so you can use the App Store, unless you have access to another computer to download it from with your Apple ID. Remember it is about a 3.4GB download.
Good Luck
