boot sector of /mnt/dev/fd0 does not have a boot signature

Hi,

I'm having very bad troubles with the installation of red hat linux 4.1
I used the boot disk and the CD to install everything and it went fine,
but only the creation of a bootdisk didn't work. It asked me where to put
lilo, and then it said "error". So I booted linux with the bootdisk with
"rescue" and tried to create a bootdisk by typing the folowing:
      * mount -t ext2 /dev/sda4 /mnt
      * fdformat /mnt/dev/fd0H1440
      * mkfs.minix /mnt/dev/fd0 1440
      * mkdir /flop
      * mount /mnt/dev/fd0 /flop            --> didn't work -> "invalid argument"
         and
      * mount -t ext2 /mnt/dev/fd0 /flop      --> didn't work eather -> "invalid argument"
*      * cp -p /mnt/boot/chain.b /flop            --> couldn't do that !
      * lilo -C /mnt/etc/lilo.conf -U /mnt/dev/fd0
            --> "boot sector of /mnt/dev/fd0 does not have a boot signature"

While trying this, someway the devices fd0 and fd0h1440 disappeared.
My question is of course: how do I restore these devices and how do I boot
Linux ?

Additional information:
I have a 486 DX2/66 with 8MB of RAM and an Adaptec scsi card with a scsi
6x cdrom drive and a harddisk of 3GB with 1 primary partition of 1Gb,
1 extended partition of 1,7 GB (divided in 5 logical partitions) and 1 last
extended partition of 300MB where I'd like to install Linux.

Thank you very much, and sorry for my bad English,

First off, you made the minix filesystem on the floppy, then tried to mount it as ext2:
mount /mnt/dev/fd0 /flop --> didn't work -> "invalid argument"
mount -t ext2 /mnt/dev/fd0 /flop --> didn't work eather -> "invalid argument"

The statement should have been:
mount -t minix /mnt/dev/fd0 /flop

As for fd0 and fd0H1440, the proper major/minor numbers are as follows:
2/0, block device
2/28, block device

So to create them, you would use:
mknod fd0 b 2 0
mknod fd0H1440 b 2 28

Also, Linux cannot be install after cylinder 1023 on the drive.  I also don't believe LILO can boot an extended partition.  So it would not be wise to put Linux on the last 300 MB of an extended partition.  What you can do is have a small (10 Mb or so) primary partition on a drive, and have the extended partition mounted in /, with /boot on the 10 Mb primary partition.  Good Luck
