Comment 65 for bug 245794

 I tried to install ubuntu 10.04 in a Fujitsu Amilo M7440. The dvd drive did not work, so I had to install using a usb drive. I tried to install lots of versions ubuntu, debian, xubuntu... no way.
Finally I found a strange solution from other forum, it worked but I do not know why: I wrote zeros in the partition where I wanted to install ubuntu. So:
a) First I boot with a ubuntu 10.04 in live mode from the a usb drive. You have to write "live" when the "boot:" prompt appears.
b) Once booted, open a terminal, and write: "sudo dd if=/dev/zero of=/dev/sdXY", where X is the letter of the disk and Y is the number of partition where you want to install ubuntu, e.g., /dev/sda1. If you are not sure of which it is, write "sudo fdisk -l" to list all of the partitions.
c) Now, try to install in the usual way.
This worked for me, good luck.
