Good morning yeahbaby5 and welcome to CH
OK 1st do you have a good back up of your data.
Use F8 key during boot to get into the Advanced Boot Options menu.
From the Advanced Boot Options chose the Repair Your Computer option.
Click Next and login to your administrator account on the computer. Your administrator account is the account created the first time the computer was turned on.
Click Dell Factory Image Recovery and DataSafe options and follow the onscreen instructions. Please keep one thing in mind the DataSafe should work for saving your data but nothing beats have good reliable back up's that you know are good.
If this is not what you are talking about please let us know using this method will restore the PC back to factory condition.
For most Dell PC's there is not really a restore Disc. There is a Windows 7 Disc and a driver / program disk. If your version of Windows 7 is say Home premium 64 bit you can use any windows 7 HP 64 bit disc and use your COA (25 digit lic number) this will be 5 groups of 5 letters and numbers to install windows 7. But your COA can only be used with what ever version of windows 7 the key is for.
Please let us know how you make out, Mike
