System Details:

Asus Sabertooth 990FX motherboard

AMD FX-8120 CPU

16 GB DDR3 1600 Corsair Vengance RAM (4x4)

EVGA Nvidia GTX-560Ti video card

2x Dvd/cd rw dirves

1 Bluray RW drive

1 Orico USB 3.0 & eSata panel

1 Sabrent floppy bay card reader w/USB 2.0 port

760W pc power & cooling PS

OCZ agility 120GB SSD (Windows 7 Professional 64bit installed in an approx 80gb partition, NTFS. There is also a "System Reserved" partition shown in disk management at 100mb in size, also NTFS)

That leaves about 32GB usable free, un-partitioned space in which I hoped to install Ubuntu.

However when I run the Ubuntu 11.10 AMD64 installer, it doesn't show there is even an operating system installed. It just shows the entire drive as free-unpartitioned space.

Just not sure what to do here. I was thinking about using the Wubi installer, but i don't know about that. Is the performance reduction pretty drastic?

Thanks,

can you click on try ubuntu instead of install, then when you see the desktop, press ctrl+alt+t and in the terminal type the command sudo fdisk -l and then post the result in the question. that way it will be clear for us. – suli8 Apr 4 '12 at 22:56
any way, when it does prompt you with the options, does it say, install ubuntu alongside windows? – suli8 Apr 4 '12 at 22:58

No, it gives me the following: INSTALLATION TYPE This computer currently has no detected operating systems. What would you like to do? Option 1 = Erase disk and install Ubuntu Option 2 = Something else (you can create or resize partitions yourself, or choose multiple partitions for Ubuntu. I chose option 2, but it just shows the entire hard drive as upartitioned, available space. – KichigaiDave Apr 5 '12 at 0:29

so it seems that your drive has GPT on it. and it creates confusion somehow.

actually there is an identical question here: Installer doesn't detect existing partition table/windows 7 partition

so the solution is to install gdisk from the software center,while in live cd, (try ubuntu), and then launch it, and there you have to delete the GPT partitions ONLY. reboot, and then you will get your right partition table back.

and always make sure you have a backup of your important data before dealing with partitions. good luck

OK, I'm on the live CD and I go to the software center. In the search box I type "gdisk" and there are 0 search results. – KichigaiDave Apr 5 '12 at 15:14
that is strange. click on the dash (upper icon with ubuntu logo on it) search for software sources, and launch it. and make sure that community maintained (universe) is checked.if not, mark it, and then update the repos. you should see it then. – suli8 Apr 5 '12 at 16:02
if that doesn't help, please see these links for more info. ubuntuforums.org/showthread.php?t=1934554&page=2 and this partition-tool.com/resource/GPT-disk-partition-manager/… – suli8 Apr 5 '12 at 16:10
What do you need by "update the repos"? Because I still can't see gdisk after checking "community maintained (universe)". – KichigaiDave Apr 13 '12 at 3:54
by that i mean, open the terminal, and type: sudo apt-get update – suli8 Apr 13 '12 at 11:20
