I had two hard disks on which I had setup Windows XP and Windows Server 2003 to dual boot. Last week I disconnected the two hard disks, added an old IDE hdd and installed Ubuntu on it. As long as the ubuntu hdd is the lone one installed in the pc it works fine. But when I connected all the three hdds to the pc, ubuntu does not boot. However Windows XP boots flawlessly, though it cannot "see" the ubuntu hdd which has an ext4 filesystem.
I dont want to dual boot ubuntu and XP by installing them on the same hdd on different partitions. I want a separate dedicated hdd for Ubuntu. Could someone please help me on how to do this ?
