upgrading to vista

now i didnt really see any other topic like this or a FAQ about this, but i keep running into a problem while trying to upgrade my computer to vista.

i have the dics it takes to upgrade to vista ( atleast i beleive its all the discs i need ). one is black and says 'insert this disc first' - ' this dvd will prepare your system and guide you through the windows vista upgrade process' . disc 2. says ' windows vista home basic express upgrade', those are the 2 discs i have and i beleive those are the 2 discs needed tp upgrade. now the main problem i am running into, is my 2 cd drives are not reading the disc, in my normal cd drive, it keeps saying 'please insert cd', on my other cd drive which is dvd compatable, i am able to click on it, and open a blank folder.

so i thought that maybe it works the same way i had to reinstall my windows program and have it run on the start up of my computer, which ended up going to a blank black screen while my cd drive kept trying to read the disc in it, but wouldnt go any farther.

now im not sure what exactly is wrong, whether it is my cd drives ( which seems to work perfectly on everything else ), or the discs itself, now the disc are HP discs made for my HP compac laptop, which i would like vista on my desktop. i dont know if it matters that the discs are HP, rather then actual Dell discs. and whether or not im doing something wrong or will have to buy all new discs.

any one got a idea?
