-
- Here's one method that worked for me. I installed DOS and Windows onto an
- empty partition. I installed OS/2 over this as a same-partition install
- (I think IBM calls this DualBoot) -- this is the method that does not involve
- extra partions, but requires to choose your next operating system WHEN YOU
- SHUT DOWN instead of when you boot. This resulted in BOOT.DOS and BOOT.OS2
- files being created, containing the DOS and OS/2 boot sectors.
-
- I then booted into DOS and installed NT. This copied the DOS boot sector to
- BOOTSECT.DOS and replaced the physical boot sector with an NT boot sector. I
- then used debug to grab a copy of the NT boot sector (debug;l cs:100 2 0 1;
- rcx 200;nboot.nt;w), and copied the resulting file over the BOOT.DOS file.
-
- When I next boot up, if set for OS/2 I boot into OS/2; if set for DOS, I boot
- up into the NT boot loader, which lets me choose between DOS and NT.
-
- Others may have more clever methods, but this one works for me.
