Hi, I tried this but had to realize that I don’t have such a button.
I only have the 3 Button ACPI/IOAPIC/VT.
Is it possible that this is a new feature only available in newer Versions? I’m still on 1.5.6

Yes, I was right in my previous post – PAE is obviously available from 1.6.0 – see http://forums.virtualbox.org/viewtopic.php?t=6101

Again – the thing that also helps is hinted here at tombuntu: http://tombuntu.com/index.php/2007/09/05/making-ubuntu-server-work-in-virtualbox/

Henning I tried the method listed above but it didn’t suited me for the following reasons:
1. First I have to download that bulky kernel and install it, its both bandwidth and time consuming.
2. By installing older kernel you are degrading urself (unless it’s the only option left i wudn’t recommed it)
3. There was an easier option available.
But still thanks for pointing out the link at-least it’s good that an alternative exists.

I have no clue what PAE means but enabling it as you suggested cleared up the error and allowed it to boot up, thanks!

Thanks a bunch, that works a treat! What is PAE and why is it needed after installing the guest additions?
