I am installing os2 warp 4. I have 3 partitions - c: HPFS 1024mb startable, d: fat 1024mb, e: HPFS 1024mb. After partitioning and formatting I continued with the install. The first part failed on the loading of the second disk. When I restarted the process I told the program to format the c drive as a HPFS and it did then continued with the install. The first part now finished and told me to remove the diskettes and restart hit enter to restart the system and continue with the installation. I do but when the system reboots I get an error DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. I have not found a way to make the c drive boot. yet.

Hi. I've never tried to deal with more than 2 OS/2 partitions at a time. You might want to try blitzing the disk and only creating on 1024 MB partition and a boot manager partition. Set the boot manager as startable and the 1024MB partition as installable. Assuming you can get the 1st partition set up then try advanced installations for each of the other partitions. It's worth a try.

I'm using 2 OS/2 partition on my machine (C: to maintenance and D: to work) and I can boot both using boot manager, did you tried to recover the master boot record? (fdisk /newmbr) ?
