When I try to install Ubuntu 10.10 on my desktop, the partitions menu that appears during the installation doesn't detect my sata hard drive. I have Windows 7 on a partition, left a space unpartitioned, then tried to install it. Couçdn't detect the disk, so I booted to live ubuntu, and created a ext3 partiton with Gparted, it still doesn't detect. Also tried completly formating the disc. Still Doesn't detect. The strange thing is that in the ubuntu desktop when i boot with Live usb, the disk is there. I was also able to create the partition as i described before.
