I am using dual boot with Win Me(Upgrade from 98) and XP. I want to keep only Win 98. Is it possible without reformatting hard disk? How? If not please advise step wise how to format hard disk.

First make a Win 98 boot disk. Then the only way I know is to get a copy of Partition Magic, install it on the Win ME and format the partition with windows XP on it. Then turn off the PC boot with the Win 98 boot disk at the a: prompt "format /mbr" to get rid of your select OS screen. Then use the Uninstall option for Win ME to go back to Win 98 if you used the Archive files option. If not then you'll have to back up your files and completely re-install Win 98 if you want to go back it instead of Win ME. Do the following below. 1. Put your Win 98 boot floppy. 2. Select boot without CD-ROM support 3. At a:/ prompt 4. a:/fdisk <enter> Partition Hard Disk (Single Partition): Follow these steps to set up your hard disk: A. First delete all active partitions. Go back to main menu. B. Select from the FDISK menu "1. Create DOS partition or Logical DOS Drive". C. Select "1. Create Primary DOS Partition". FDISK will verify drive integrity. Then it will ask if you want to use the maximum available size of the disk for the primary partition and SET IT ACTIVE. Enter "Y". The system will allocate the whole disk to the partition, and that's that. D. Press {Esc} to exit FDISK. E. Reboot: Reboot the system using either the Reset button or the ({Ctrl}+{Alt}+{Delete}). Make sure the floppy disk is in its drive, since you still need it. Note that you may get "Invalid media type reading drive C" errors while rebooting. This is normal at this stage. F. Format Primary Partition: From the "A:" DOS prompt, issue the following command: "format c:/s". Do not forget the "/s", as this is what will make your C: drive bootable. You will get a "scary" warning message such as "WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST. Proceed with Format (Y/N)?". Since of course there is no data presently on drive C:, just enter "Y" and the system will format the hard disk. The program will show you its progress as it formats and at the end will prompt you for a volume label. Enter one if you wish. G. Remove Boot Floppy: Eject the boot floppy from the floppy disk. H. Reboot: Reboot the system using either the Reset button or {Ctrl}+{Alt}+{Delete}. The system should boot up from the hard disk this time, and stop at the "C:" prompt. Note that if you get an error such as "NO ROM BASIC, SYSTEM HALTED" or "No boot device found" at this stage, this means you forgot to set the primary DOS partition "active". Reboot from the floppy, run FDISK again and use option 2 to set the primary partition active, then reboot. If you get an error like "No operating system", this means you probably forgot the "/s" parameter when formatting the C: drive. Put the floppy disk back in the drive and then return to step F. http://www.windowsreinstall.com/win98/install98floppy/index.htm Then click "Begin Windows 98E Install Step by Step Guide" on down the page. I hope this helps out. It's a lot of info so you may want to print it out before your begin. PDN

or you could just boot from your ME boot disk, type sys c: at the a prompt and you'll never see the dual boot menu again. then in ME, reformat the other drive.

You could try that but in my past it wouldn't allow it.
