Windows Vista Premium drive letter issues

[hobo baggins]

Hello all.

I'm having problems running cds in my labtop with windows vista. I've
instaled some apps despite this, but others refuse to autorun or install,
throwing an error that reads:

E:/
The directory name is invalid.

Now, I deleted the empty D: "DATA" drive that the Vista install put onto the
drive, it took up about half the drive, alongside the C: drive labeled
"VistaOS". Now it's just C: and an unlabeled partition (primary, about 7.81
GBs). I don't know if that's the OS or no, but Vista isn't letting me run CDs
normally, with the previously mentioned error.
What should be done to resolve this problem? Thank you for any help that can
be offered.

The hidden, unlabled partition, is the recovery partition.
If you ever have to run a recovery it will likely restore your laptop to
give you back the D: data partition.
Many suppliers use this type of setup, two partitions with win installed to
one

You could try locating the cd drive in hardware, removing it, then rebooting
