virtualbox.org

I have a working ubuntu 8.10 install on vbox 2.2.0 and also need to set up an instance of ubuntu 7.04. After New I select linux/ubuntu, the adj memeory to about 1gb, the create a new hard disk (IDE primary master). The cd is in the drive but on start I get

FATAL: No bootable medium found! System halted.

What am I missing?

First off you don't need 1 gig to do Ubuntu, kick it down to 512 to help conserve system resources.
Next thing I would check is whether the CD is readable. Can you see the contents on the host drive?
Also depending on how the CD was made it may not be bootable. Certain CD burning software does not play well when creating an ISO file.

Thanks Perry. It turns out that all I had to do was to enable the CD before I booted it. I guess for some reason the CD drive was enabled automatically when I did my first vbox setup? I don't recall enabling it for that one.

I set the memory to 1gb because this box will be used to test some stuff that really hogs ram. On a physical pc usually 2gb is best. But I know so little about virtual machines...maybe I made the wrong choice. If I set to 512, it wouldn't reallocate to a larger amount if needed, would it?

No it won't reallocate but it will cause more swapping. If you see a slowness then you can increase it to what it is you need. I run a lot of things in Ubuntu and Windows servers and do not see a slow down with 512 allocated. Then again your milage may very

Did you manage to get an OS installed or not? Please stick to one problem per topic.

Yes I did get ubuntu installed fine.

I only mentioned the memory because I figured it might have something to do with the issue, and the responder was kind enough to suggest that the default memory allocation was sufficient.

Memory doesn't really matter that much. Ubuntu can run on 128 MB if it has to.

Anyway, you got it working, so I'm locking this one, before it becomes a spam place.
