Thanks

This may shed some light on the subject.

#15: Error parsing number.

This sounds like something wrong with the config file. (/boot/grub/menu.lst)

Can you boot up with a Live CD?

What is the configuration?---e.g. dual-boot with windows?

Was it once working? Problem appeared after a change?

if you can see a grub menu just after bios then you can press c for commands to get to use the troubleshooter link in my signature.

2) you will be wanting to set up root and use the find to look for your menu.lst as it is likely to have gone missing probably never installed.

3) can you tell us what changes you made recently? is this a new install? etc

It is a new install not a dual boot.It installed fine, but upon reboot the orange ribbon stuck at the beginning and didn't move.Advice I received on this forum was to delete "splash and quiet" fom the grub menu. When I did this I got the error 15 message.I can access the grub menu and the "c" command.What do I put in here please.I have access to knoppix live cd, how can I use this to get ubuntu 7.10 working again. Thanks for your patience.

1) troubleshooter will show you how to boot your system but with your postcount you may be better off with a live cd

2) boot the cd....you should see icons on your desktop when it loads for each hard drive partition.....click on each and drill down into folder /boot until you know which partition holds boot.....it may be hda1 or hda5 or sda1 or sda2 etc.....if you can remember tell us how your partitions are setup if you get into trouble.

also in using knoppix, navigate on the left hand side panel to see where knoppix is mounting it, (making accessible to read) it may be /mnt folder subfolder hda1 or hda5 etc

once you know its (eg) sda3 then right hand click each partition icon you went into and select option "umount'

now open a terminal and type su to get root powers in knoppix
next is a command to mount an example...change it to suit your partition for /boot

mount -t ext3 /dev/sda3 /mnt/sda3.....(make sure /mnt/sda3 folder exists b4 doing command)

I am not sure if ubuntu uses ext3 so use konqueror to examine the file /etc/fstab to see what format your / is formatted as examples are ext2 ext3 reiserfs xfs

now start konquror in su mode by

konqueror

then navigate to /mnt/hdX (or sdY)/boot/grub/menu.lst and open that file

put a # symbol before the line that starte with splashimage

on the kernel line for ubuntu which will read something like
" kernel (/boot or noboot showing)/vmlinuz-version root=/dev/hdX (or sdY) (or /=label) and some other stuff......

delete any reference you see to splash=something

THEN save

then exit and then close down konqueror then issue command
umount /mnt/hdX or sdY.......where hdX is the same form as used in your mount command

then to be sure....re click on the icon that you discovered for your /boot and check menu.lst is how you want it and then reboot your hard drive and good luck

3) when you solve all this.....try to prevent these problems in the future with a backup system...I use partimage

In which case you did something wrong - just editting that shouldn't cause this error.
Simplest (prior to aus9 suggestion) might be to re-boot and select the "recovery mode" on the boot list. This does exactly what you wanted, without the need for the edit.
