Well, I don't usually wimp out on such questions, but in this case, I refer you to the following article on
methods to install Fedora.
You need to have a way to boot an install CD disk, floppy, or network installation, even if you "prep" the drive on another system.
You could install Fedora on another system usng a laptop hard drive convertor, then place the drive back in the Dell Laptop, but that is another story. Probably the "host" machine will have video graphics much different than the old Intel video graphics on your laptop, so you would have to overcome that obsticle.
Additionally, you would have to use the laptop hard drive as the primary master drive in the host system, to ensure that the Grub bootloader is set correctly. This way, the hard drive settings in grub will match the drive's designation when placed back in the laptop.
There are workarounds, but not for someone new to Linux.
These methods are not for the faint of heart.
