Windows 7 upgrade disc not recognized by DVD

Very frustrated

Bought an Windows 7 home premium upgrade disc for my Vista home premium pc, duly went and downloaded the upgrade advisor program before opening the package and it told me that my computer was a-ok to run windows 7 and upgrade, so I opened the package and put the dvd in my laptop's drive.

Nothing.

It makes a whirring noise, then sticks, if I click on the drive it tells me to insert a disc and ejects the windows 7 dvd.

This is the first and only DVD that has ever behaved like this, all others work.

I went back to the shop and the DVD ran on the computers there.

Why won't it run on mine?

Have an optiarc 5540a dvd drive. In a Dell inspiron 1720 running Vista 32 home premium. The drivers are up to date according to windows.

also, if the shop won't refund my money because I've opened the package (BECAUSE THE STUPID MICROSOFT WINDOWS 7 UPGRADE ADVISOR TOLD ME EVERYTHING WOULD WORK) How do I get my money back from microsoft for selling me a dud?

Also, where's a good place to buy a macbook as I have had enough of this ****

First Vista and now this.

Try another DVD drive since it is clear from your tests that it is your DVD drive and not Win7.

You can load it to a flash stick using another computer to boot isntall instead of from DVD: Extract ISO using ImgBurn, Download UltraISO trial, load ISO file, Write Disk Image to flash stick from Bootable tab, click Format button first.

Cool, I guess I will have to try that - wish the DVD would just work though, and that I could work out why my drive doesn't work only for this disc

I did try searching for the same problem, but tended to find people having problems AFTER the install. I guess I will have to try to do a flash drive install or borrow an external drive from somewhere, thanks both for your replies.
