Hi everyone.
I've planed to install Ubuntu Lucid Lynx 10.04 x64 on my rig.
dual boot setup
windows 7 preinstalled
Intel ICH10R RAID0
manual partition setup
200mb ext3 /boot
2gb swap
100gb ext4 /

GUI installer can see my RAID and allows me to create this partitions manually.
But when install begins
i'm getting error :
parts: #5 - /boot; #6 - swap; #7 - /

things i've tried:
/boot => primary or extended
/boot => ext3 or ext4
same error

fdisk -l from Live cd shows me separated HDDs without RAID0 wrap (sda and sdb)

Also in advanced section where i can configure boot loader default is /dev/sda, which is part of RAId_0. I'm checking isw_dgaehbbiig_RAID_0 as location for loader, assuming that this would be MBR. am i doing this step right ?

Please help.
Thanks in advance.
