"error: no such disk" when boot ubuntu 9.10

Asked by Jorge

Hi
I had Ubuntu 8.10 working fine on a 360G HD on a Gateway laptop MX6025, now I decided to go to 9.10 using the entire disk, so I said ubuntu installer take entire disk when partitions screen, everything went fine until reboot, I got a:
"error: no such disk" Press any key to continue...

It returns me to "GNU GRUB version 1.97~beta4" screen where I can select:
- Ubuntu, Linux 2.6.31-14-generic
- Ubuntu, Linux 2.6.31-14-generic (recovery mode)
- Memory test (memtest86+)
- Memory test (memtest86+, serial console 115200)

Selecting any ubuntu option just return me to the:
"error: no such disk" Press any key to continue.

I was able to install 9.10 on a 40G HD same machine but never on the 360G. I have used all my tricks but no successful.

Please help.

Are you having both disks simultaneously in your machine? If so, which one is slave, which is master? And could you please post your menu.lst (located at /boot/grub/menu.lst).

It is a laptop and allow only one HD, I had to replace it to test the other HD
Remember I was not able to boot and see /boot/grub/ but I remember seeing that as an external(usb) HD it had only one file, I think /boot/grub/environm (something like this).

What I did is manually select the partitions and selected ext3 filesystem instead of ext4. it avoid the "error: no such disk". I suspect it is because it is an old laptop with a new and large HD for this machine. Well, having ext3 crated a GRUB error 18 problem but I know how to deal with that. I had this error 18 since 8.10 so it is not because 9.10.

For people with error18 what I did is have an external usb-HD connected(may be flash memory works too) during installation and when select the partitions get in to advance and instead of the default hd0, selected /dev/sda1, sometimes it does not work so try /dev/sda/.
Some how it avoid error18

Finally yesterday I was able to boot 9.10, and it is great.

What I did works even I do not understand well what happen. If someone may explain, ... welcome.

Thank you
