Perhaps You could try a bootable CD of another source (cd-/ dvd-writer)
or another os just to be sure that it is not a problem caused by this
special Ubuntu-CD but by the drive.

Have You checked / compared the md5-checksum ot Your CDs _after_ writing
/ burning?

Sometimes downloads go wrong or the burning process adds this infamous
"malicious  bit" that prevents You from working with this special Ubuntu-CD.

Just my 2 cents ...

Wish You and Your whole country all the best!
