I try to istall Ubuntu 12.04 on my Lenovo U310 laptop. The problem is here: GParted see my HDD, all is okay. But when I launch installation - there is no partitions to choice.
I think it happens, cause U310 has 2 HDDs (normal and SSD) and may be boot process contains some magic inside...
Can anybody help with it?
After some experiments I found, that problem is in intel Rapid Start Technology (iRST). It uses SSD drive as cached disk, and HDD as accelerated. And both of them work in RAID0. That's why Ubuntu installer can't see table partition.
So, to fix it, I disabled (Ctrl+I during loading notebook) acceleration of the 500 Gb hard drive and all is fine.
I'm sorry if it copybook maxims, but maybe it helps to someone.
Love Ubuntu :)
