Hello, I am going to install DOS 5.0 on a modern machine. I have 3.0GB of unpartitioned space(many OSes to choose from :)), and I'm wondering how to partition it. I have used SPFDISK and created a 900MB FAT16 Partition(HEX CODE: 04 - FAT16 <32M).When I boot the disk it asks to format the partition, and i let it do it. My BIOS warns me that the boot sector is being modified. I then press 'Y'. Then the setup says "There was an error formating the main partition. Press F3 to exit and correct the problem"
Any Idea Why? Am I doing anything wrong?

"My BIOS warns me that the boot sector is being modified"
That is your (nearly useless) 'antivirus' protection enabled in the CMOS. Maybe turn it off?
Is the partition set as active? Is it a primary partition, and seen as "C:" by DOS fdisk?
Why DOS5 instead of 622?

MS-DOS looks to install on the C: Drive and within certain parameters unless you are using a 3rd Party Boot Manager. If you install MS-DOS first prior to any other O/S it creates less problems, and is what M$ recommends:

Not only the partition must be of the right size, but it should be located under the 1024 cylinder limit. That is why it is recommended that DOS be installed first. Some boot managers and emulaters may get around these problems.

I have tried different methods and found this works for me, usually with DOS and NT4.
If I have a hard drive over 4MB which is unusual, use PTSDOS 2000 as recognises 4GB FAT16 partitions.
