Good afternoon yeahbaby5
OK if your mom's disk's were made using
Dell UT then no you can't use them. Long story short if she made them using Dell's UT they were made with her PC's hardware and software.
If she has a "Dell printed" windows 7 Home Premium 64 bit disk and a "Dell printed driver / application disk" then yes you can use only her W7 disk but her driver disk will be different than yours. So if this is the case borrow her disk and use
your COA / key numbers to install the OS and then activate your OS with MS.
When you install W7 on your PC even if W7 has all the drivers for your PC still go to Dell's web site and still install there drivers, just a word of advise
Please let us know how you make out, Mike
