External Hard Drive cannot start up with OSX?

Recommended Posts

So, I got leopard and everything on a dvd and started it up and it asks of course for a destination. I have an old 20 gig harddrive from an old laptop, so I erased everything on it with Disk Utility and when I went to select it it has the red exclamation point on it saying "You cannot install Mac OS X on this volume. Mac OS X cannot start up from this volume." I checked the info of the drive and it says it's bootable. I was wondering if anybody knows what this means and if I can fix it, Thank you!

You must change the format of the external hard disk in disk utiltiy. There is a tutorial on apple.com on how to do this. it is different for intel and ppc. I ran into the same problem but quickly solved it and got it installed on an external hard drive.

I sent u a message, but I dont' know if you got it. Do you happen to have the link somwhere (prob not, but that's ok) or what you put in to search. I'm using a MBP and it's such a pain in the a$$ to find stuff on the apple site

 

edit* I went on the apple site and found one thing about it and it showed the drive as being a black enclosure pic on the desktop. I was wondering if yours looked like this or like mine which is a little yellow enclosure with a usb 2.0 icon on it

sorry i did not get your messege im at work with very limited net access. I don't remember excatly what i seached but i think it was somthing on the lines of "install os x on an external hard drive" I don't have a mac at work here and i can't remember exectly how to do it but the tutorial on apple.com was very straight forward.

For anybody else out there having this problem do the following:

 

Go to Disk Utlitiy

Select your problematic drive

go to Partition

Select option and select GUID Partition Table

Select OK and then Partition

 

The drive will be ready now for you to install

 

Hope this helps other ppl!
