How can I make Grub boot 2.16 from hda3? (Solved)

[robertito]

I have 1GB RAM and HD partitioned hda1,2,3 and swap. Partitions hda1 and 2 have 2.15CE working fine, loaded from an iso burned on a CD,
I wanted to try 2.16 on hda3 and followed the same procedure as for 2.15, and although it works OK from the disc, and apparently loads on hda3, attempts to run it always fail with the message "Error 15: File not found"
I've tried various GRUB settings, but without success.
Any ideas what to try next, please ?

robertito,

for grub problems it's best if you post a copy of your menu.lst file, as often others might see something you're missing like a typo etc. where are initrd.gz & vmlinuz on hda3, in /boot, or under / directory? and is menu.lst pointing to their location?

also at the grub menu type c

then find /boot/vmlinuz so we can all know where it is.

esc to get back to grub

Not sure what vmlinuz does but it wasn't in the boot menu with grub, so I moved it so it looks like hda1 and 2 do.

Now the error message reads:
Kernel panic - not syncing: No init found. Try passing init = option to kernel

So what do i do next, folks ?

Your grub menus entries are the types used for normal installations. See this example:

title Linux (on /dev/hda1)
root (hd0,0)
kernel /boot/vmlinuz root=/dev/hda1 ro vga=normal

A typical co-exist install would look like this (lots of differences)


title Linux (on /dev/hda1)
root (hd0,0)
kernel /vmlinuz root=/dev/ram0 ro vga=normal
initrd /initrd.gz

You will have to figure out what kind of installs you made.

Then adjust the grub menu.lst and vmlinuz and initrd.gz locations to match your menu.lst.

Also remember that GRUB / Linux is stricter than an English teacher with a bun in her hair. You have to have everything exact, syntax, file locations, spelling, everything. You also have to be a careful worker, or she'll slap your knuckles with a ruler.

[muggins]

it seems you've done a co-exist install & grub is looking for initrd.gz, so either modify menu.lst for co-exist, as mentioned by bruce, (making sure that the command for initrd.gz points to where initrd.gz is), or if you want a normal install, like your other partitions, just re-install pup2.16...it takes 10 minutes max.

[robertito]

muggins.....my 2.16 works fine from the CD, but when I try to install it using the Universal Installer, it does not recognise the CD files. Is there some other way of installing from the CD, without using the Puppy Universal Installer ?
Thanks for your interest....

[muggins]

i think you'll find that what's happening is when you run the universal installer, it looks for vmlinuz on the mounted cdrom, but if you run pmount or mut after booting the cdrom, you'll see that the cdrom isn't mounted.

so the solution is mount the cdrom before running the installer and it should work OK.

if not, just mount the cdrom & copy vmlinuz, initrd.gz, pup_216.sfs & zdrv_216.sfs to /mnt/hda3, then alter menu.lst, as mentioned by bruce above:

title Linux (on /dev/hda3)
root (hd0,2)
kernel /vmlinuz root=/dev/ram0 ro vga=normal
initrd /initrd.gz

N.B. with co-exist, (aka frugal), install it's /dev/ram0 not /dev/hda3. also, if you have initrd.gz & vmlinuz in /boot, then you have to alter menu.lst accordingly.

[robertito]

I got into a complete muddle, so I re-formatted the disc with three ext 3 partitions plus swap, installed 2.16 on hda1 and a MBR Grub, and now it boots from hdd and does everything I want to do (for the moment !) So thanks for your interest folks, and I'll keep my fingers crossed.
