I just recentley formated an old computer for the fun of it,and I start my computer after it with NO FLOPPY! Then it dosent say no Operating System,It says:Invalid System Disk Replase The Disk Then Press Any Key! I need help Thanks,KeoghJacob

When you say, "NO FLOPPY," do you mean there is no diskette in the floppy drive? If it is set to boot to the CD drive, is there a non-bootable CD in it? If not, and if your PC is booting to the hard drive, then the hard drive may have crashed. 1 Corinthians 15:3-4

I have no floppy in the drive there is no driver for the cd rom so,and the computer has had many operating systems on it before,Windows 95,Windows 3.0.I need a copy of dos to setup a driver.

The message you are getting is normal when there is no bootable operating system found on the hard drive - it's wording varies depending on the mboard bios brand and version you have. - if you want to use Dos on the drive, the drive can easily be made bootable simply by booting with bootable floppy for the Dos version and formatting the drive again with the s switch, which places the bare necessity system files on it - at a minimum IO.sys, MSDos.sys (or their IBM named equivalents), and Command.com, or by using the SYS command if the drive has already been formatted. E.g. Boot with a bootable floppy for the Dos version that has at least Format on it as well as the system files that make it bootable, and at the A: prompt, type: format C: /s (press Enter). OR if the floppy has SYS on it, you can place the system files on the hard drive without having to format an already formatted drive again - at the A: prompt, type: sys c: (press Enter). Either way, your hard drive will then be found to be bootable, but it won't have any other data on it yet. If you get or have the set of floppies used to install a Dos operating system, the first floppy in the set is bootable, and installing the contents of all the floppies makes the hard drive bootable, and also installs the other operating system files for the Dos version. CD drive support is built into the later Dos operating systems and Windows 95, but you must add appropriate lines to your Autoexec.bat and Config.sys and have, and point to in those files, a driver (*.sys) for the CD drive. If you also want Windows 3.1 or 3.11 on the drive, you then use a set of install floppies or use an install CD to install that. For Win 95 and up, you can't just install the bare minimum system files - you have to install at least the minimal contents of the Windows operating system CD onto the drive. There are customized Dos versions out there, such as 7.x, that you can use - e.g. 7.x is a Win 95 or up version stripped of it's graphical stuff - but I know nothing about them. The last Microsoft version was MsDos 6.22.MsDos 6.0 could be updated to 6.2 with a specific upgrade floppy; I don't know it that applies to 6.22 too. IBM and Compaq may have released a similarly numbered version. The drive can be bare of data when you start Setup, but in that case - if your CD drive is NOT so old it isn't capable of booting from a CD, and if you CAN place a CD drive before any hard drive in the boot order in the bios Setup, then you can boot from a full version Windows CD. (if it's an Upgrade CD version, that's a different matter - they are not bootable). - if your CD drive is so old it isn't capable of booting your computer from a CD, or if your bios is so old you can't place a CD drive before a hard drive in the boot order in the bios Setup, for Win 95, 98, 98SE or ME, you need a bootable floppy for the Windows version that loads CD drive support on it - e.g. a Startup Disk made in the same version of Windows 98, 98SE, or ME has that CD drive support. Just type Setup when the files finish loading from the floppy. For Win 95, 98, 98SE or ME, the full version CD originally came with a bootable floppy, but later they stopped doing that. They were essentially the same as a Startup Disk made in the operating system, except they had the added option of Run Setup in their initial menu (at least, the one for 98SE does). If you don't have one, the place you make a Startup Disk in 95, 98, 98SE is in Add/Remove Programs - Startup Disk tab. I haven't used ME much, so I don't know if that applies to ME too - if not, you can get a Startup Disk for ME on the web. ..... Side notes. For Win 98 and 98SE, if you have a hard drive larger than 64gb, you need to get an updated version of Fdisk and copy it to the Startup Disk floppy. The Startup Disk is made from files on the Windows CD and the original Fdisk has a bug and starts counting the partition size over again at 64gb, or multiples of that. What Fdisk will see in those cases is e.g. ~80 - 64 = ~16 gb, or ~120 - 64 = ~56 gb, or ~160 - (2 x 64) = ~32gb. Get the update you install on a working Windows 98 or 98SE installation here: http://download.microsoft.com/downl... If you use a Startup disk to Fdisk the hard drive, you must copy the updated Fdisk from Windows to the floppy. If you boot/install Windows from the Win 98/98SE CD, you cannot Fdisk/Format a hard drive larger than 64 gig - use the Startup disk with updated Fdisk instead. The update is supposed to be installed on a working Win 98 or 98SE computer. If you don't have that, you can get the updated Fdisk.exe on the web. In it's Properties it's size is 64,460 bytes, and it's original date is 5/18/00 (depending on where you get it from the date may be something else - the right one is 64,460 bytes). ..... 2000 and up CDs have never come with bootable floppies. If you can't boot from a CD for whatever reason, a set of Setup floppies can be made from a program included on the 2000 CD, or you can get downloads on the Microsoft site to make a set of 6 Setup floppies for XP, both of which load the same files the initial part of Setup does when you boot from the CD, then after that Setup proceeds normally from the Windows CD. If you make a bootable floppy when using Format in 2000 or XP, it makes a bootable ME floppy. There is no set of floppies that can be made for starting Vista's Setup. Your computer bios and your CD drive must be capable of booting a bootable CD. Requirements for using a floppy drive and booting from it and problems you may have.

What OS do you plan on installing? How large is the drive?

I plan on trying to find a download for Windows 95 and OSR 2.5 on floppies if you could email it to me ? "Even If Its Old Its Still A Good Computer"

Ask anyone you know who has been using computers for a long time - if they still have a Win 95 CD they will probably give it to you free. There were floppy sets you could get to install the original version of Win 95, but I don't think any were made for the later versions. Most people bought the earier versions of Win95 which is useless for drives larger than 8.4gb (you have to make four 2.1gb partitions on the drive) and has only poor USB support built in. Win 95 OSR2, available only on CD, is the best version and has FAT32 support for drives larger than that, and better USB support, but they are relatively rare. Most were Upgrade CDs - you have to at least provide a floppy for a Dos version in order to install it. You are much better off getting a full version Win 98 or better still a 98SE CD. Ask anyone you know who has been using computers for a long time - if they are using 2000 or higher and still have a Win 98 or 98SE CD, they may give it to you free, or sell it to you cheap.
