Thumbs down mount: /dev/fd0 is not a valid block device


What does this mean and how can I fix it? I'm trying to create a boot floppy so that I can choose whether to boot Suse 10.1 or Windows XP and have had bad experience writing the grub installer to a hard drive. The problem is when I try to install the grub loader it gives the message

Quote:
Running "embed /boot/grub/reiserfs_stage1_5 (fd0)"... failed (this is not fatal)
Running "embed /boot/grub/reiserfs_stage1_5 (hd0,0)"... failed (this is not fatal)
Running "install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (fd0) /boot/grub/stage2 p /boot/grub/menu.lst "... failed

Error 21: Selected disk does not exist
There is quite a bit snipped off that but the stuff that is there is the actual problem. I guessed that meant that it couldnt find the floppy drive and when I tried to go into it on knoqueror voila it comes up with the message

I tried to mount it in superuser mode using...

Quote:
mount -t auto /dev/fd0 /mnt/floppy
but get the same message. Any ideas anyone? Thanks in advance.

Is the floppy disk formatted?
One mounts the filesystem and not the device so if the floppy is unformatted, it won't work. Also check whether the vfat kernel module is loaded. ( /sbin/lsmod | grep vfat ). That said, some programs might write to the device directly instead, in the case of a floppy,

Another option is to write the grub boot loader to the linux root device, copy the first 244 bytes of that device to a file, copy the file to the windows c:\ drive and add an entry to windows C:\BOOT.INI file.
This will allow you to use Window 2000, XP or NT's loader and chainload grub or lilo. There are instructions on the web usinb google or searching this site.
