Hi,
I have worked with Ubuntu for few years already and installed Ubuntu and other distros to a lot of PCs, but this type of problem I could not resolve by my self.
I have Desktop PC with SATA HDD, where I have installed Win7, no problem, everything works. I wanted next to it install Ubuntu 12.04, however when Ubuntu from live CD or USB boots it does not see the hard disk. I can see only the USB drive from which I boot. Gparted and Fdisk, don't see it. I reboot the system, the Win7 boots without any problem.
I have tried a lot of things, but non of them seems to be working:
In bios I have changed Sata Mode to AHCI, SATA mode and RAID mode - no effect (while Win boots on AHCI and SATA mode).
Bios detects HDD and I an choose booting device. The HDD is not shown in Standart CMOS setup page, where only PATA disks are shown.
Tried different SATA connectors to motherboard (there are 5 of them) - no result.
My HDD is 2TB, which is not detected, but I also tried with old SATA 40Gb hard disk, the result is the same, the HDD is not detected.
One good thing is that I know, because tried, that Ubuntu boots and can be installed from PATA HDD, but I would like to install it to SATA. As I don't have the very old PATA disk.
I wanted to update the BIOS, but there is no newer, spent a lot of time looking for it. Motherboard - Packard Bell MCP78PVM-PM, BIOS released 05/01/2008, Computer model: Packard Bell Imedia 8841.
"Gparted recovery disc" also does not detect the HDD. Meaning that debian based OS will not detect it. I have a bad feeling that the same will be with any Linux distro.
Tried 32 and 64 bit Ubuntu, with no success.
I think here I should ask what Win7 can do better in SATA HDD detection than Linux and how can I add this to Linux (without recompiling kernel).
Please suggest what more could be done. I don't want to be stuck just with Win7, it's so not interesting.
