Hey everyone, pretty new to Ubuntu / Linux in general. I'm trying to install Ubuntu 12.04 off my USB stick onto my laptop to dual boot against Windows 7. I've scoured the forum and the internet in general to solve this, but can't figure it out for the life of me.

When I initiate the installer, I am never prompted for the "Installation type". I am instead directly taken to a partition table, in theory to select where I would like to put the OS. However, there is no partition table! Which seems weird because I can see everything under GParted.

Below is some terminal stuff that a lot of other posts request.

I can provide more details for things I have attempted if you guys would like, but perhaps this is enough for now. Thank you very much in advance for your assistance!

Is this an Ultrabook with the 32GB a small SSD for caching? Or is that just another flash drive?

The SSD cache is often Intel SRT which uses RAID and then the installer cannot correctly see drive.
Other issues may be NTFS is hibernated or needs chkdsk which it needs after any resize. Always use Windows to resize & reboot to let it auto run chkdsk.
Also drive was originally gpt and you used Windows to convert to MBR as that does not totally remove old gpt backup partition table.
Also some BIOS settings can make a difference.

You have to make space for Ubuntu/Linux on your HDD. There are two ways to go about it:
1. SHRINK your 480Gb partition to make space for Ubuntu. You can leave the created space as 'Unallocated Space', and let the Ubuntu installer take care of the further setup when you choose 'Install Alongside Windows'.
It will create two partitions from the given 'unallocated space', one for '/' and one SWAP.
2. SHRINK your 480Gb partition to make 'Unallocated Space' you need for Ubuntu. Boot with Ubuntu Live DVD/USB and open Gparted. Proceed to make your own partitions and when installing Ubuntu you HAVE to choose 'Something Else' option to guide your Install the desired partition. Remember: 'msdos' partition table has ONLY FOUR PRIMARY partitions limit. To bypass this limitation you have make an EXTENDED partition from the 'Unallocated Space' and make LOGICAL Partitions within it.

If you take charge of the installation manually then it is advised that you create a separate DATA or '/home' partition for your data.
20Gb LOGICAL Ext4 '/' [for Ubuntu System files]
2-4Gb LOGICAL LinuxSWAP
All the remaining GB LOGICAL Ext4 '/home' [for your personal DATA].

Also make sure your Windows7 is NOT hibernating.
Also make sure Intel SRT is switched off in BIOS/UEFI.
Also disable 'Fastboot' if you have it, in BIOS.
