alternate

I am trying to install 11.10 as dual boot with Windows 7. I have all partitioned well as you can see here:

I burned the Alternate CD ISO to a CD. Boot from it and followed instructions to Partitioning.

There, I configured the LVM partitions as follows:

Volume Group

ubuntu-vg - Uses Physical Volume /dev/sda7 380GB - Provides Logical Volume home-lv 60GB - Provides Logical Volume root-lv 60GB - Provides Logical Volume swap-lv 6GB

That is all I want (note that my /boot is outside of LVM)

Then when I say that all is Ok and to write it to disk and continue with the installation, I get the following error.

!! Partition Disks No root file system No root file system is defined Please correct this from the partitioning menu.

What should I fix and how?

I tried issuing the "Revert changes to partitions", but nothing happens. It seems that the LVM configuration has already been written to the CD.

HELP!!
