Installation finished. No error reported.

This is the contents of the device map /boot/grub/device.map.

Check if this is correct or not. If any of the lines is incorrect,

fix it and re-run the script `grub-install'.

Let's start with the basics first. Is the your bios set to boot from the floppy drive as the first boot device?

[leafleaves 0]

right,

not this bios problem,

i know this basic bios settling .i have studied and being a computer engineer for a company over 8 years long time.

 

my question is my the boot floppy image problem.

from the rh0 installing wizip guide from cdrom,i selected no

installed the grub starter in the hard drive.after i finish installing ,the directory /boot/grub/ have nothing files inside.

 

now i want to install the grub starter into floppy ,using this floppy boot rh90,also say via the grub boot floppy start up my rh nine point zero operating system.

In the /boot/grub directory, do you have a grub.conf file?

 

If so, can you post the contents?

 

I assume that you saw the RedHat guide here?

 

If not, and I am going by remote memory, try typing on as root user;

 

redhat-config-boot

 

See if this package is installed. If it is not, try installing it off the cd.

 

If it is installed, you should be able to install grub to a floppy.

have the directory /boot/grub/ on my rh90,in this directory ,have lots of named stage file,and .map file,

just not have grub.conf, emphasize again---------

 

just HAVENT grub.conf

.

i have read lots of material about grub install,lots of material refer to the grub.conf file.and then ,why doesnt my computer have this file---grub.conf???

really feeling confusing.what happen???

 

 

using command #grub-install /dev/fd0

making the diskette doesnt boot successfully.

 

maybe casue this file:grub.conf???????????????????

complementarity two points:

figure 1:

i have right using root user login.

figure 2:

i have entire installed rh90 OS.

I have just been looking around. See if your grub.conf file is in the /etc/ directory.

 

If it is at /etc/grub.conf, then post the contents, if you can.
