How to Install an Operating System on an External USB Hard Drive:


You may have an external hard drive you want to use for more than just document backup.
In this situation, you can install an operating system onto your external hard drive. By doing so, you will be able to run your external hard drive as a fully functional operating system.
If your primary hard drive ever crashes, you will have a backup option unavailable to those who simply use their external hard drives as file and document backup.

1) Plug your external Hard Drive into your Computer using the USB cable. Insert the installation disk for your Operating System into the CD/DVD Drive. Turn on or restart your Computer.

2) Boot from the installation disk. You may have to press a key once prompted to boot from the installation disk.

3) Accept the license terms and conditions. Read through these carefully if you wish to understand your legal rights as a user. If you disagree with these terms and conditions, you may want to purchase a different Operating System.

4) Choose your destination drive. Your external Hard Drive will likely be the E: or F: drive. By default, the C: will represent your main Hard Drive and the D: will usually represent your CD/DVD Drive.

5) Begin the installation. Your external Hard Drive will install the Operating System. You will now be able to run that Operating System off of your external hard drive.


Hope this helps.

Error Installing OS X on Mac G4


I would suggest sticking with Tiger. How to reinstall:

I assume you put the Tiger disc in the drive and rebooted while holding C or you changed your startup disc in System Preferences.

As you are clicking through the installation program, look for a "Options" button at the bottom, I believe. Click the button. Look for the "Archive and Install" option. Careful: **DON'T select "Erase and Install" unless you want everything erased off your hard drive.

There is a small risk of data loss when installing the operating system. You should have backups of your important pictures, documents, etc. You should have backups of your home folder. [The free Carbon Copy Cloner can make a copy of your hard drive onto an external hard drive. It can also make a disk image you can save to an external hard drive, if there's other stuff on the drive.]

Select "Archive and Install," which will save your previous OS in a folder and install Tiger. It will not touch your pictures, documents, etc.

After that, you should be good to go. If not, let us know and we'll do our best to help.

how do i clone my hard drive onto an external hard drive


Are you using Windows? If you are using Windows, go to Start => Programs => Accessories => System Tools => Backup. In the backup wizard that opens, choose which backup type you want and you can choose your backup destination. Choose your Seagate Expansion external drive for your backup location so that Windows can store an image of your current system into your external drive.

I want to backup my computers (4) and have maxtor partitioned and used at purchase time, but now when I connect it I get no prompts or choice of hard drive to back up. How do I go about back up?


You have a varity of option to do your backup depending on the type of backup you want to do.
1 Documents and folders
To backup your document and folders you can just copy the Documents and folders to the external drive.
You could also use the backuo feature of the Operating system you have like windows backup to backup your documents and folders.
2 System backup of your system.
You can not use a copy accross to do the complete backup of your system. You can use the windows backup to do this or a third party backup software.
Windows Back for Windows 7.
Click on Start ----- Controll Panel ----- System and Security ------- Set up Backup ------ Select where you want to save your backup ( the external Drive you connected to your system) in the box ------ Next ----- Choose the files or drive you want to backup and click next ------- Review your backup settings and save settings and run back.

This will save your files to the external drive you added to your system.
