Custom installation multi-boot with multiple partitions

I have downloaded the iso file and listed it in the grub configuration. The iso is in a directory under the boot directory on sda9, my main Ubuntu partition. When I boot, I can select the option to boot with the openSUSE iso. The installation process begins with no problems. During the process, I tried to customize the partitions with the following objectives.

No separate home partition
install openSUSE to the root of sda5
Use sda7 as a swap partition

I abort the installation process because the installation report indicates that it will delete several important partitions, including sda3 (win7), sda8 (NTFS data partition) and sda10 (system rescue cd - gentoo). I cannot find any option which would enable openSUSE to ignore these partitions.

Here is a list of my partitions configuration:
Device Boot Start End Blocks Id System
/dev/sda1 2048 206847 102400 83 Linux
/dev/sda2 208894 418056191 208923649 f W95 Ext'd (LBA)

/dev/sda10 412530688 418056191 2762752 83 Linux

Any ideas on how to get around this problem?
