I want to dual-boot Ubuntu Desktop 12.04 on my new ultrabook which has

• an Intel i7 3517U processor
• 6GB RAM
• Windows 7, 64-bit
• no CD/DVD drive

I created my bootable USB stick using pendrivelinux.com with the "ubuntu-12.04.1-desktop-i386.iso". I am following these directions because they include nice screenshots; however, I do not get very far in the process. I am able to boot into the Live Desktop, and then I try to install onto my hard disk. Here are the series of actions that I take next:

1. First, I see this ( http://i.imgur.com/vucYH ) window, and click 'continue'
2. Then I get this ( http://imgur.com/2wESc ) window, and click 'continue' again
3. This appears:

and I get worried because it seems like there is no recognition that I have Windows installed. According to the directions I am following, I should see /dev/sda1 and /dev/sda2 partitions. In the drop-down menu at the bottom the only "Device for boot loader installation" is /dev/sdb and no information is shown. I am hesitant to click 'Install Now' for fear of what it might do to Windows. 4. I click 'Quit' and cancel the installation, but then about 5 seconds later this ( http://imgur.com/a/yXi0C ) window pops up (I have expanded it to full screen to scroll and show all the details). 5. Another second later this ( http://imgur.com/vxcrN ) comes up. I'm not sure how relevant this is.

Does anyone have any insight into this issue?? Why does it not show my current Windows partition? What would happen if I tried to continue with the installation process?

Thanks!
