If you have one of the old Intel video chip-sets mentioned earlier, at the Grub menu, press e to edit kernel parameters, and add the i915.modeset=1 option.And since your computer BIOS anyway lacks a boot-from-USB option, the BIOS won’t boot from the USB drive either. 9.04’s boot loader will be inactive, and thus would not cause the system to boot from the USB drive. Ubuntu 10.04’s boot loader will now be in control, and it doesn’t have an option to boot from the USB drive. Create a startup disk using a CD or disc image. You could remove the USB drive, but even if you leave it in, there shouldn’t be a problem. When the installation is done, restart the computer, as usual.Click the “Install Ubuntu 10.04” icon on your desktop to launch the installer, and install Ubuntu as per your preferences (overwriting an existing installation, or into a new partition).You will be presented with a Grub menu from the USB pen drive select the first option to boot into a live session of Ubuntu 10.04.

Reboot the computer (in my case, my laptop).The kernel parameter i915.modeset=1 prevents Ubuntu 10.04 from having problems with old Intel graphics chipsets like i915. The kernel parameter cdrom-detect/try-usb=true specifies that if the kernel file is not found on a CD-ROM, try a USB location as a fall-back. (hd0,4) is the location where the current OS (Ubuntu 9.04) is installed.

Add the following boot stanza to /boot/grub/menu.lst (use sudo gedit /boot/grub/menu.lst to edit it as root):.

Depending on the brand of the USB drive you are using (or the partitioning/format options it was subjected to), the label may differ - and hence the mount point, and so the path above may need to be changed. Note: KINGSTON is the label (and thus, the automatic mount-point under /media) of the filesystem on the USB drive I used.
