Nitro:
Basic steps:
1. Make sure your Windows 98 CD is not very badly scratched and is not an upgrade (but a full version) CD.
2. Back up all the files you want to save to a CD (if you have a CD-R or CD-RW optical drive) or to floppy disks.
3. Make a Windows 98 or Me bootable floppy disk.
4. Restart your computer with the boot disk (you do not have to enable CD-ROM support yet).
5. At the command prompt type FDISK and press Enter.
6. Follow the instructions to enable large disk support, delete all the partitions, make one large partition formatted with FAT32 (not FAT or FAT16)
7. Restart the computer with the boot disk still in the floppy drive (you do not have to enable CD-ROM support yet).
8. At the command prompt (i.e. the A:\>) type FORMAT C: and press Enter.
9. When the format operation is complete, restart your computer (this time be sure to enable CD-ROM support).
10. Put the Windows 98 CD in the optical drive.
11. At the command prompt, type D:\Setup and press Enter.
12. The Windows 98 setup program will begin; just follow the instructions on your monitor.
