Re: Having trouble installing Ubuntu 12.10 for dualboot with Windows 7
Usually if the install alongside option is not there it is an indication that you have used up the 4 primary partition limit of bios based systems.
Many OEM's use all 4 by default, so you would need to delete one of the partitions to have the ability to make a new partition for Ubuntu.
Be careful if using Win disk management, because if you try to make more than 4 partitions there it will convert the disks to dyamic disks which is a Windows only format and Linux will not be able to use the disk at all.
Why, not an issue these days, use 32 bit on 32 bit systems, 64 bit on 64 bit systems, a few years ago this was true, not anymore.
Also, I would recommend going with the 32-bit version of the Ubuntu Secure Remix for a dual-boot setup. It might save you lot of headaches.
@OP Boot into the live cd/usb and select "try" to get to a live session and in a terminal (ctrl+alt+t) copy and paste
then copy and past the result back here so we can see how your system is partitioned.
