What happens when I swap the position of sda and sdb?
How does grub2 locate the hdd drives? By way of UUID or through its position in the bios?
For instance, suppose I install Natty on sda (first HDD) and later want to install W7 on sdb. On installing W7 the installation software looks at the bios and wants to install the OS on sda (physically the first HDD).
If I swap the two hdd physically will sda (the drive with a unique ID) now become sdb under Natty or remain as sda. Will grub look for the UUID and not sda/sdb?
