Ubuntu won't boot in Parallels on one machine

[NutritioN]

I've been trying out Linux on a trial of the latest Parallels version (4560) and got it working well as a test. This is on a Macbook Pro, and the latest Ubuntu iso.

The machine I'll end up setting up is an intel mac mini, we have a full licensed version of Parallels for this but an older version (3186).

Both virtual machines have an identical setup but it seems virtual.hdd files aren't compatible across these versions (really annoying as I thought I could set it up on my machine then take the virtual.hdd to the other)

Anyway, the mac mini linux VM black screens after the PRESS ENTER TO BOOT message from Ubuntu. It just hangs when he initial Ubuntu logo goes. Tried verbose debuggin but can't get anything. The initial Ubuntu screen is different on each Mac, why would that be if it's the same ISO is being used?

Any clues as to why Ubuntu won't work on the Mac mini? SLAX and DSL live distros work fine.

Is the Ubuntu image you're loading 32 or 64-bit?

Tried both, come to the conclusion that 64-bit doesn't work on Macs?

 

[BillytheImpaler]

64-bit will only work if your mac has a 64-bit processor. Core duos are 32-bit. Core 2 Duos are 64-bit. Which do you have?

Well I've got the 32bit version to work on the Core2Duo (MacbookPro) but can't get it to work on the CoreDuo (MacMini)

Installed the newer trial version of Parallels and it works fine. Will have to get the upgrade on our licence.

Cheers.
