OK, this is how things look right now. I've got a dual boot PC at home with RedHat 7.1 and Windows 2000. It boots using the NT loader. My hard drive is cut into 3 partitions; 1st 2Gb is for Linux, next is 4Gb for Win2000 OS (NTFS), 3rd is 16Gb for Win2000 Programs (NTFS). Can I add OS/2 to this system without formatting? If I did, where would I add the HPFS OS/2 partition? If I have to format, how should I partition to have all 3 of these? I'd appreciate any help, Thanks!

You could use some utility such as Partition Magic to move things over and make some more room. Or you could add another hard drive. eCS (OEM Warp 4.5) has the Logical Volume Manager, which allows you do drive spanning. I would suggest that you just get a second hard drive. They hardly cost anything these days. Of course you might have some remapping problems, but OS/2Warp can be installed and booted from a drive other than "C". DEFGHIJKLM............

In order to dual boot Win 2000 and os2 you should use BOOTMAGIC a product provided by Partition Magic 7.0. aprox. $65.00. IBM's BOOT Manager will not work with win 2000 unless you modify the boot sector manualy. Not a easy thing to do.

This will not work. I have tryed it a feew years back. I tryed with OS/2, Linux and W2k. The reason for this not working is becuse of the limit of 3 (or was it 4 w/boot partition for Boot Manager) primary partions.. I could be mistaken here, but I don't think so... And if you do get this up and running. Let us know how to. Good luck!

I've gotten the OS/2 Boot manager to work when I had DOS v6.22, Win 98, WinNT 4, Linux, OS/2 Warp4 all on the same machine. I would recommend installing OS/2 Boot Manager at the end of the drive, takes up about 4 mb. You can install any HPFS drive at any point of the HD, it doesn't need to be in the first 2mb, like FAT16. Partition magic works wonders if you are in a bind now, but I would recommend deleting the NT boot loader, I think you can modify the boot.ini in Windows and then install OS/2 Boot Manager at the end of the drive, assuming you have that as free space. Nice thing about having OS/2 Boot manager at the end of the drive, no viruses to date can attack it, because it isn't on the master boot record.
