1- dont say your post is urgent. its no more urgent than any other question (which is still not at all urgent).
2- maybe it WAS urgent.. considering you didnt have time to write the full word for 'blue' or 'your'.. id recommend spelling words out and not leaving out letters.
3- does the install let u specify manually your cd drive? can you check your hardware and see if it is compatible on the HCL (
http://www.linuxquestions.org/hcl/)?
4- what do you mean it stops at 86%? do you put in the cd, powerup the computer and before it even starts isntalling it says its detecting devices, but stops there? or is it halfway through the installation process? etc
