Hi. I'm new to Linux and am unaware about most of the technicalities of this OS. Recently I installed Red Hat 9 on my PC. My existing OS is Win XP Pro. After successful completion of the installation when I rebooted the machine, this is what I found in the OS choice menu: I've no clue where that second Linux option came up from. And then, after a few days, on booting I found the PC wont start. All I got was a black DOS screen with "grub>" as prompt. Being unable to boot, I deleted the Linux partition using XP boot CD. Yesterday, once again I tried to install Linux, and yet again as before found the same OS choice menu after installation. Iâ€™ve installed Linux using the same CD on my friends PC without any problem. Could any body tell me whatâ€™s happening here?
