Ubuntu 10.10 not detecting sata drives

Issue start date: june 2009 to till now
Issue: Unable to install ubuntu
hardware profile
--------------------------
Asus p5nd motherboard
nvidia chipset
sata emulation set to sata not raid.
seagate 2*250gb drives
earlier these drives were in raid but in the beginning from feb 2009 i disabled raid and using the 2nd 250gb as a back up for the first primary drive.
asus driver cd has the linux drivers but it is not seeng the drives when booted from linux
Troubleshooting:

1.Tried booting form the ubuntu 10.10 but checks out the requirements section fie stating that it has the required 2.disk space but in the next section it won't detect the both of my 250 GB seagate sata disks.
3.The seatools which is a windows based diagnostic tool for their product is also not detecting its own harddisks.
4.tried changing the sata emulation to every possible option like sata, raid and other such settings in the bios but no go.
5.tried the wubi installer from the disc inside windows but no go.
6.tried debian again today but it is unable to see the existing partitions in the disk.
7.tried suse linux and it says that the parted is unable to modify the disk where i want to dual boot but it does detect the drives.
8.tried booting from norton ghost and it just shows error for the disk that i want to dual boot.
9.tried every dos disk tools from hiren's boot cd 13 but no go.
10.trying with Redhat enterprise linux 5.3 and but no go.
11.Try sudo apt-get remove dmraid but no go,
12.Reinstalled my windows 7 (the c drive was 132 gb filled with my favourite customized applications and windows and games but i gave all that up for nothing) ultimate and installed win 7 ultimate x64 N edition but no go.
13.<1> I tried to boot from ubuntu again by restoring by BIOS to the defaults but no go
14.I tried change sata DMA settings and ide prefetch mode settings (every combination with raid enabled and disabled) but no go.
NOW I KNOW WHY LINUX IS NOT AN OPERATING SYSTEM FOR EVERYONE IRRESPECTIVE OF THEIR TECHNICAL ABILITIES. ITS FOR ONLY THE LUCKY ONES.
