How to unistall Linux OS

Hi,
I am having two Hard drives. One with Win 98 and other with Linux 8.0. I would like to uninstalled Linux 8.0 keeping win98 intact on other disc. Can I simply remove hard drive having Linux Installed. If not, guide me how to achive it.
Regards.

The easiest way to remove Linux is to boot with a Windows boot floppy and use fdisk to delete the partitions on the second hard drive.

Btw,Linux is not an OS.Linux is the kernel in the GNU/Linux OS.

It's the same thing, everyone just knows it as Linux. I call it just Linux although I know most of the software is GNU software and the kernel is Linux.

It's not the same,but yes,unfortunaly that's how everyone knows it.You seem to be well informed about this,so you should help the GNU project and call it GNU/Linux.Also read this essay:
http://www.gnu.org/gnu/linux-and-gnu.html.People are always surprised when they find out how much percent of the code is Linux and how much the GNU project.

I do tell people how much is GNU and Linux is just the kernel but it's just harder to say GNU/Linux than it is to say just Linux. If GNU wants their name recognized along with Linux then they should target the major distros and conventions like LinuxWorld first. I know Debian recognizes itself as GNU/Linux on their site but I doubt Red Hat, Mandrake, etc do.

Also, anyone who actually knows a small amount of Linux usually knows that a majority of the software for Linux is written by GNU.

These are technicalities that few people are interested in getting involved in. It's nice to know that "Linux is a kernel, Mandrake is an Operating System", but most people don't have the time or inclination to discuss the semantics of the issue when dealing with the common GNU tools typically included with Linux..... when it comes down to it on an individual application level (for larger applications), the distinction becomes clear, so GNU gets credit where credit is due (such as with large, well-recognized, and GPL'ed apps) and doesn't get credit where credit wouldn't be given to anyone regardless (such as with bash). This is mainly due to the fact that, when using something as common and low key as bash, it's unlikely that you're going to be thinking "Gee - it's great the such-and-such wrote this nice shell for me to use!". However, when you fire up Emacs, it's relatively clear that you are running a large, complex, useful tool. It's also fairly clear who made that tool, so they get credit.

coming back to the original problem:
after deleting the partitions you MUST run "fdisk /mbr" from this boot-disk or on the next reboot, lilo will hang! (if you are using lilo, i don´t know about grub, but still you should use this command.)

Of course we all know Linux is in fact GNU\Linux but when somebody says "Linux 8.0" he clearly has no clue and he must be informed.

LILO will boot any partition that still exists. FDISK /MBR might not do it.

if you don´t mark the linux entries as "optional", it won´t! (no linux distro i dealt with had this option set by default...)

why not? can you please explain?

The "optional" keyword is used to tell LILO not to bail out with a fatal error while it parses lilo.conf (map creation time to be precise), doesn't make a difference once it's installed on the MBR.

As for FDISK well I can't explain! As far as I'm concerned it never wiped out a MBR virus, LILO or anything else for that matter, it actually never worked for me. In the past when I used Windows mostly I had to reinstall it in order to get a working boot record back. I've been told that using the MBR of a floppy could do it but I never tried it.

On the contrary - I've had the opposite experience. The undocumented fdisk /mbr tool / switch is probably the ONLY DOS or Windoze tool I've ever used with a 100% success rate (about a half a dozen times). I don't see why fdisk /mbr wouldn't work actually - it indiscriminantly clobbers the MBR and *ahem* "fixes" it for Windoze.

[offtopic edit]
As for the HURD / Linux debate - I personally have gotten into the habit of simply referring to a distribution by the distributor's name followed by release number. Example: Red Hat 8.0. However, I do refer generically to a whole non-specific distribution as "Linux" rather than GNU/Linux - and I'm quite unapologetic for it!

last time i did that, lilo hang with "LIL--" or "LIL010101010101010010101010" or similar when i removed a harddisk that was setup to be booted from linux. same for deleting a partition. "optional" removed this problem.

don´t have two harddisks in one machine anymore, nor any recent linux installation, so i can´t tell for sure...

Probably because the map file got overwrote. In my case I only removed the partition but the data was still there... Happened to me when I removed Slackware which is where I installed LILO from. I guess he could move the files needed by LILO to the windows partition since it doesn't care about and wipe out Linux from there.
