Re: probs installing Lynx x64 on RAID0 ich10r (dual boot)
As you have found the 10.04 live cd will be useless to you with the raid. You should be able to use an earlier version live cd to crate and check the raid0 partitions with the proviso that if it is 9.04 or earlier you will have to 'sudo apt-get install dmraid' within a live cd session to do so. I would recommend pre-partitioning the drive with the earlier live cd. Also make sure you are creating the partitions within an extended partition (your results so far suggest that you might be trying to install on another primary partition - win 7 by itself takes two primary and you are limited to four total including the extended).
My own experience was that an install to raid0 extended partitons went flawlessly. You do have to hit the advanced box in step 8 to direct grub2 mbr install to the root of your raid. Look for it in /dev/mapper/. It is the symbolic link normally designated without the partition numbers (ie mine is nvidia_aebhdfib). The install will fatally fail if this last step is not performed (fixable but in you system would require chroot commands).
Post if you have more questions.
