Please Help! Urgent

Hi

I'm working away from home this week, so I ordered a mac pro to be delivered to where I'm working.

I took my system drive with 10.5 out've my home mac pro (it worked fine when I put it in an older mac pro) and took it with me.

This new mac pro will not boot from it. Nothing happens when I instruct it to boot from it. It boots fine from the drive it came with.

Please help

One question, is your home machine for sure an Mac Pro with Intel Xenon CPU's and not a PowerMac G5? Sometimes users confuse the two.

If both are really Mac Pros I know the install DVD's are machine specific, but since this a hard drive with 10.5 already installed it should boot I would think.

When you hold down Option and select the drive, what happens?

edit: dtravis beat me to it and is better than I at this

Absolutely. It's either late 2008/early 2009, 8 core, 4gb ram. It's running the latest version of osx10.5

The hired computer is brand new - although I'm not certain about whether it's the single or dual processor model. I wouldn't have thought either would be an issue though.
I've removed all it's drives, inserted my system drive, and on booting, nothing happens.

Ideas? I'm in a whole heap of it here!

One other thing I should have asked, if you boot from the drive that came in the new Mac Pro with the old drive plugged in, does it show up in OSX?

Yes. I can select it, but upon booting nothing happens

Ok,

The piece of software I need to run is installed on the drive I brought with me. How can I get this to run on the new computer?

With both drives plugged in I can see the software I need (Pro Tools). I stupidly don't have any install disks with me, or even an internet connection fast enough to download anything. Can I create an installable version of it?

Only thing I can suggest is to run the Migration Assistant to import your user account, data, apps and system settings from your old disk.

Whether it will import everything for ProTools to run properly, I don't know.

Ill try that

I should be able to run applications from another hard drive shouldn't I? They don't all have to be installed on the system drive?

You could try launching it from there. Am only guessing that ProTools may install files into other system folders that are needed for it to run properly.

If ProTools is a drag and drop app vs one that has it's own pkg installer, then you'll probably not have any problems.

Yeah, it won't run as it is. This migration assistant may prove an answer - when the hire company get back to me with the **** computer password.

No idea as to why it simply won't boot from my hard drive?

Probably a driver issue. I have seen only a couple of reports of those that wanted to install Leopard on a newer machine that shipped with Snow Leopard and it wouldn't install. No bottom line answer as to why.

What a joke.

Both computers are running 10.5, it should just work.

I can't believe I've been this slack with my preparation, complete eejit.
