I'm new to Linux and Ubuntu, and I think I have a problem.

I have an Acer Aspire S3 with 20GB SSD and 320GB HD. I installed Ubuntu 12.04 64bit on it today, and when it asked about partitions, without knowing better, I erased the partitions.

There is some information at https://help.ubuntu.com/community/AspireS3 about using the SSD and HD efficiently, but since I deleted the partitions, I don't know what to do.

How can I recreate the partitions mentioned in the above link so that I can take advantage of having SSD and HD?

I installed GParted, but I don't know what I should do now, and I don't want to screw things up further. I greatly appreciate any help that can be offered me.

EDIT: I was playing with GParted, and I just realized that I can see dev/sda and dev/sdb, so perhaps I didn't do something horrible to my partitions. I am also sorry for asking such (dumb?) questions. At this point, is there a way to tell whether I have actually screwed up my partitions?

Thanks, Joe
