memtest and check cd for defects functionality missing

Asked by Fred on 2010-05-04

In previous versions of Ubuntu I could run a memtest scan and check the CD for defects from the Ubuntu CD.

This functionality seems to be missing from Ubuntu 10.04 "Lucid Lynx".

No this function is not missing. You should press Esc when the disc starts.

 Maybe a hint on the screen when the disc starts would be helpful.

As joris said, just press Esc when the disc starts.

Please boot entirely from Ubuntu live install cd and when the system start to boot from cd you will see two bottom screen icons (keyboard and man inside circle ) please press space (choose your desired language) then a screen textual center menu will appear to you with this items in it:

Try Ubuntu without installing
Install Ubuntu
Check disc for defects
Test memory
Boot from first hard disk

Then please select Test memory to be sure your pc RAM memory have not any issue

Can you help with this problem?
