can i dual boot 10.04 with windows 7?

The installer will deal with the 4 partitions limit by itself. It can create an extended 4th partition and place all the Ubuntu partitions in this container. So that's not a problem.

The installer should ask you for your account login/password just after repartitioning the harddrive. So maybe it has a problem to create the new partitions.

So I have a few questions:
-Where did the installer failed? Just after partitioning ?
-Can you still reboot the computer in Windows 7 ?
-Could you boot the computer on the LiveCD, open the Gparted partition editor (it's in System, admin) and tell us what your hard drive looks like ?

thx!

May be your Ubuntu live install cd is not perfect or it can't be read from your cdrom drive please verify it...

Here some general note and howto:

The main ubuntu site is this: www.ubuntu.com and the download location is this
http://www.ubuntu.com/desktop/get-ubuntu/download

install a torrent client i suggest you http://deluge-torrent.org/ if you are using Windows and download the iso using a .torrent link from here:

your response seems very relevant to my problem. i used a live cd from Linux
Format magazine, so it should be good. i tried the install
several times with the same result: after creating the partitions, the
installer did not ask me for user name and password, which i had
created earlier in the install, i believe. instead the ubiquity program
crashed and the installation terminated, leaving ubuntu live still running.
then i could reboot to windows 7, which displayed the partitions created by
the ubuntu installer in the format expected.

Hi guys. I was able to get the amd64 iso image to install correctly today using the same partition setup as caused problems with the LXF 32 bit installer. So I no longer have a problem.
