Why does Redhat need a boot disk!?


Ok so I have installed Redhat Linux and Windows 2003 Server on my machine and both are on seperate hard drives and it is setup to dual boot and it does this just fine. However... When you select to boot up Linux it just sits there with GRUB on the screen obviously waiting for the boot disk (and when you put the boot disk in it boots just fine). I am wondering why in the hell I even need a boot disk to boot linux. I mean this isn't practical. I don't want to have to boot Linux with a boot disk at all. I want it to boot up without any disk. I am wondering if anyone can help me in telling me how I can make it so I DO NOT need a boot disk. Maybe I am missing something but needless to say can anyone help me?

Chris

Here is the official page from the redhat manual for 8.0. It tells me that I will ned a boot loader if I do NOT want to have to boot from a floppy disk.

http://www.redhat.com/docs/manuals/l...ootloader.html

Well I can tell you for a fact I installed GRUB and it still comes up when you try and boot Linux with the blank screen that says GRUB which is looking for the boot disk.

Also, here is the contents of my grub.conf file so that you all may help me better...

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda6
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.18-14)
root (hd0,0)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/
initrd /initrd-2.4.18-14.img
title DOS
rootnoverify (hd1,0)
chainloader +1

Sorry, I was mistaken...


Does it ask you for a boot disk when you choose it? Or does it just do nothing? What exactly happens. Sounds like grub is pointing to a bad kernel image or something.

I will try and explain this as best I can very simply as well. I start up the computer and after the BIOS loads and everything it just sits there with the word GRUB blinking on the screen. Now on the other hand if you start the computer with the GRUB boot disk I created during the installation of Redhat it will boot up Linux just fine! So basically when you don't have the boot disk to boot Linux it just sits there with GRUB on the screen. Also can you tell me if all Linux systems by default are meant to boot with a boot disk? And if so why? Im really new to Linux.

No, they aren't. I never use a boot disk... except to install the dang thing the first time.

Hmm, I never liked Grub, it always gave me troubles. Is it flashing in a pattern or anything? Or does it repeat anything other than just flashing GRUB? Have you looked through RH's forums? I'd imagine this problem would be fairly easy to look up over there.... Does Grub load at all? Is it how you choose whether to use Windows or RedHat? If it doesn't load at all, I think you made a mistake in where you installed it. I have to always install my bootloaders on my MBR.

grub does have some nice features though r_jensen... cause if you screw up your config file you can still boot it with manual commands in the grub command line.... and it actually understands how to read the filesystems. So if you try and boot a kernel that just plain ain't there it'll let you look through the file system and find where it really is.

Uhh, I'd feel hesitant if my bootloader tried to boot a random kernel if it didn't find the one I had it pointing to. Maybe that's just me, though. I do like the option to use command-line booting, but if you know how to set up Lilo properly, you shouldn't have any problems. And just in case you do, there's always a bootdisk so you can fix lilo.

No pattern at all with the GRUB. It justs sits there and GRUB is the only thing on the screen.

I suggest trying to reinstall Grub, and install it on your MBR. But if anything goes haywire, don't hold me liable.
