Is a separate, older, and different operating system than XP Home Edition. It is the grandaddy of all Microsoft operating systems.
Unless you know how to work the command prompt in DOS, you really cannot do much of anything with it, except to format and partition your hard drive. If you do know the arcane commands, and the syntax and the language, then it can be a very useful operating system.
Limitation of formatting and partitioning in DOS is that it cannot see a drive larger than 2 GB (Gigabytes), which as Kees says above, is too small for you to use. If you have a drive that is 40 GB, then you would have to make 20 partitions to use all the available space, and DOS will not let you do that. It cannot, as it was never designed for this.
As Microsoft has introduced each newer operating system, each of them has brought greater capabilities built into them, from Windows 3.1 to Windows 8 Consumer Preview. Along with each successive introduction has come more RAM, faster processors, and larger hard drives.
The only way this will work for you is to obtain a legal CD-ROM copy of Windows XP before you use the floppy disk set to start the CD-ROM drive and then, and only then, install XP from there. XP will format and partition the hard drive for you when you begin your installation.
You need a full retail copy of the XP disc, and it should come with SP3 as part of the package.
Having SP3 already installed will save a lot of time in updating your system. As it is, there are now over 100+ updates that must be installed after you successfully install XP Home Edition. This will still take some time to do.
Newer computers do not need a floppy drive to start them, and many made today do not come with them. Merely placing the install CD-ROM in the CD-ROM bay will start the computer when it is first turned on, and installation will begin from that point on.
Without the full XP installation disc, there will be nothing to install as an operating system.
Your XP CD-ROM will start your system for you when you insert it in the CD-ROM drive bay and turn your computer on. So that is what you need. You should not need the floppy set.
To ensure that no viruses remain on the hard drive you want to use, use this free hard drive wiping program, http://www.dban.org/ Using this program will ensure that no data or viruses remain after running it, and the hard drive will be in pristine condition, like new, in factory condition. As it is quite thorough, it will take quite a bit of time to complete. After that is done, you can install XP without any worries.
So I would not bother with the floppy set.
We can also point the way for you to find the drivers you will need to make XP run as it should. It's a Dell 5150, right?
