The kernel VFS maintains a list of mounted filesystems in
/proc/mounts. If your root (/) filesystem and /boot are not mounted or
not found in /etc/fstab then some of the tools you're trying to use
might complain.<br>
<br>
What does "cat /proc/mounts" return? Is it a list of mounted
filesystems and devices? What is in /etc/fstab (do "cat /etc/fstab" to
find out). If /etc/fstab is broken or not there, just do "cat
/proc/mounts > /etc/fstab" to rebuild it. You will need to be root
for that of course.<br>
<br>
Then try your grub tools again.<br>

Jim, the otuput to the 1st command is: brw-rw---- 1 root disk 8, 0 Nov
23 15:28 /dev/sda and the /dev/sda is in yellow<br>
The output to the 2nd is: mknod: '/tmp/sda': Operation not permitted<br>
Then I realized I was not root, did that and tried again. Same for the
1st output. 2nd output is: back at the prompt, then for grub-install
/dev/sda the output is, 1st line: grub-probe: error: cannot find a
device for / (is /dev mounted?). 2nd line: grub-probe: error: cannot
find a dvice for /boot/ (is /dev mounted?). 3rd line: Could not find
device for /boot: Not found or not a block device><br>

Hi Bill,<br>
<br>
If you ever get a "/dev/sda: not found" type message, please do the
following to see if it exists:<br>
<br>
ls -al /dev/sda<br>
<br>
If there is no device node for that device, you either need to mount
the automagic /dev filesystem that will populate the directory based on
the device drivers loaded into the kernel, or else consider creating it
yourself. IIRC sda is 8,0:<br>
<br>
mknod /dev/sda b 8 0<br>
<br>
If you can't write to the /dev directory, then create the device node
in /tmp:<br>
<br>
mknod /tmp/sda b 8 0<br>
<br>
Then you can use your other commands such as grub-install to access
that device. The major & minor numbers on the device node "file"
tell the kernel what device driver will handle the ioctl()s. If the
SCSI device driver chain is not loaded into the kernel then you
wouldn't be able to access /dev/sda either, so make sure all the
necessary driver modules are loaded if you have any trouble using a
SCSI block device node.<br>

I think you need to mount /dev to to chroot before chrooting. Try mount
-o bind /dev /mnt/dev. I am not sure but I usually mount proc in the
chroot also.<br>

2374, 19+ Gig. The commands I used as root are as follows:<br>
