How to set up boot from Floppy (or CD)?

NickC · 06-24-2004, 12:10 AM

I just tried this out, and the bootloader worked great!

If I had no floppy in, it went straight to XP. Once I put the floppy in, it went to the grub bootloader screen.

Here I ran into trouble. I'm sure I didn't specify the drive correctly, because it's giving me an error (17 I think) that the partition cannot be found. And I'm now booting to the Linux drive on slave instead of master - with the master being the XP drive.

Can you elaborate on the changes I need to make? I looked at the /grub/menu.lst file and tried to change the linux boot from hda1 to hdb1. But there are all these references to (hd0,0) - do I have to change hd0 to hd1 or something like that? Or is that

Also, you mentioned having to change the /etc/fstab file. Similarly, do I change all references to hda into hdb? Because there are several - like hda1, hda6, etc. And if I change this on my hard drive, am I asking for trouble changing this file (i.e., will I screw it up so I can't boot in at all?!)

Thanks again!

Just a follow up on this. I figured it out and got it working!!

Thanks to everyone's help getting me set up.

One question. In the above script to get the boot loader onto the floppy, I understood the steps except for the end. What do these commands do exactly? :

Code:

# install bootloader
/usr/sbin/grub --batch <<EOT
root (fd0)
setup (fd0)
quit
EOT

# flush write caches
sync
