I have switched the SATA preference to AHCI from IDE in the BIOS. Now Arch refuse to boot with following warning:
ERROR: device '/dev/sda2' not found. Skipping fsck.
ERROR: Unable to find root device '/dev/sda2
...
...
[rootfs /]#
I have checked the WIKI and it has a remedy with 'mkinitcpio'; looks outdated. I have also found about adding one moule to initrd with mkinitrd on the www. However, I am not sure and need some guidance regarding this.
By the way, I dual-boot with Ubuntu and it booted just fine after the switch to AHCI.
Thanks.

Chrooting into Arch and issuing mkinitcpio once is probably enough to get things running again. Otherwise you need to add ahci to the modules line in mkinitcpio.conf

This is why the fallback image exists -- for when you change "hardware".
D'oh ofcourse, that's even simpler...

Thanks guys I fixed it from Ubuntu with 'chroot'. I added "ahci" to MODULES in /etc/mkinitcpio.conf and ran mkinitcpio.
I can boot Arch now.
Do I have to re-install the kernel? Do I have to add "ahci" to mkinitcpio.conf at every kernel upgrade and run mkinitcpio? Or am I OK.
Out of curiosity, regarding 'fallback image', how is it "even simpler"? Would love to know, for future reference, any pointers?

You are OK now fantab.
The fallback image contains a much larger number of modules, so you probably could've booted from that without chrooting.
Edit: p.s. don't forget to mark your thread solved.
