I probably put too much information here, but I'm not sure where it went wrong.
I was attempting to install Ubuntu 12.04 LTS beta 1 x64 alongside Windows 7. I had used Ubuntu 11.10 32-bit, but I wanted to upgrade to 64-bit, so I backed up my home folder, went into Windows 7, deleted the Ubuntu partitions and expanded my C drive. I placed the Ubuntu 12.04 files on a 4.05 GB partition of my (jailbroken) 32 GB iPod touch using the Pen Drive Universal USB installer. Unfortunately, selecting "Ubuntu 12.04 Desktop" did not recognize my ISO file, so I chose one of the options at the very bottom, I believe it went something like "Other Ubuntu (new system)" but I don't remember the exact name.
I was able to boot into the setup without a problem. I only reached a problem when I went to "Installation Type." I clicked "Install Alongside Windows" and it only allowed me to resize two partitions which total 15.7 GB. The drive selected was "SCSl1 (0,0,0) (sda) - 320.1 GB ATA WDC WD3200BEVT-7 7.2 GB I should currently have 3 partitions. One is 104MB (dell recovery), one is about 15 GB (recovery tools), and the other is about 300GB. Ubuntu noted at the bottom that 2 smaller partitions were hidden. I clicked the "advanced partitioning tool" but received Bug 939450. After going into "try Ubuntu" I was able to get the advanced partitioning tool working, but the "Install Ubuntu alongside Windows 7" tool still showed the same two partitions. I would like to split /dev/sda3 into 2 different partitions, which I was able to do when I was installing 11.10 using the "Install Ubuntu alongside Windows 7" tool, but it looks like it's trying to split /dev/sda2.
Thanks for your help!
