Specs: Windows XP, Pentium 4 3GHz
Hi folks,

Although I'm quite good with computers but not an expert I face a serious problem here.
I got an older laptop, HP Pavilion zd7000, which is a good machine for what we want to use it for.
As there was no HDD in there anymore I took one of the older ones I still have.

Now, when I instert a BOOTABLE cd of Windows XP professional he doesn't recognize this cd so he doesn't start installing. whether I take a Professional or Home version none of them boot.
If I take a bootable DVD of W7 he starts to install the program.
As the required configuration for W7m is higher then what this one has it takes some time BUT IT WORKS.

Now my question is: How is it possible that a bootable DVD runs and a bootable CD not?

I checked the CD's with my desktop at home and ALL of them boot immediately.

Does someone have an answer for this?

The drive may be worn out and can no longer read CD media. Windows 7 comes on DVD media.

You could try cleaning the lenses in the drive by using a lens cleaning kit. There are two lasers in a combo drive. One for CDs and one for DVDs. Lasers can burn out or become weak. The lens that covers the laser can get sooty from the burning process too.

The optical drive in an older computer most likely had more use reading/writing CD media than DVD media. I have had that very thing happen to drives.

✔ Best Answer
Copy the XP disc to a DVD, then see if you can boot off the XP DVD.
