Gaming How do I factory restore a laptop?

[RemixDeluxe]

Last night I decided to trade laptops with someone and we both backed up our computers but what we cant do is use the factory restore settings. I know it has something to do with pressing an F command on startup but I get the same two options for every F key I try? Is it possible to do a factory restore without a CD or am I screwed here?

Here are the computer specs on both computers

is that for both computers or can only one of them do that? Remember I told you I get the same 2 options for each F command unless theres something Im not doing.

For some laptops it's F2. Depends on the laptop which key you press to return to factory settings, but this can usually be found inside the manual or sometimes is displayed on the first screen when booting up.

If you still have problems with restoring,you can call/take it to the shop from where you bought it

Sometimes, and very rarely, you can use System Restore / Recovery and restore your computer to the way it was far before ever installing anything.
It all depends on how far back your restore points go, for example, you might have a restore point from when the first program was installed onto the computer.
If the F-Command at startup doesn't work, I'd try using the Recovery tool in the Control Panel.
