Jama's questions

When I was installing Ubuntu(12.04 and 11.10) showed 2 partitions, whereas I have 4 partitions on Windows 7: C(70GB),D(300GB),E(300GB),F(30GB).
Ubuntu is only 2 disks: one is 70GB, the latter is 677GB. But inside that disk there are no files from E and F. But when I checked in Windows, that files are exist.

This is what I got from blkid:

/dev/sda2: UUID="deac59a9-a0d0-4a69-a918-d511a9857204" TYPE="ext4"
/dev/sda4: UUID="C606C83106C82471" TYPE="ntfs"
/dev/sda5: UUID="2d3d4bf9-33b7-461c-aa88-c08caa6bef58" TYPE="swap"

And this is from sudo fdisk -l

How can I access that disks?

I've been using Windows OS before, and it's a bit hard for me copying and pasting to Ubuntu's system folders so. If i drag file or folder into File system folders, I'm getting "permission denied" error. Is there any way to copy/paste file/folders easily (not by Terminal)? Thanks in advance

I have an HP laptop with Windows 7 installed.
How can I use Ubuntu in full-screen mode via virtualbox or any other software?
