Adding OS/2 Warp 4.52 on Windows Vista Boot Manager

On this case OS/2 Warp 4.52 was already installed on an HPFS partition on the hard disk. And installed Windows Vista on an extended partition. Like always when you try to install an OS, it mess up the boot sector and removed the OS/2 Boot Manager and started the Windows Vista Boot Manager.

So, I wonder, which will be the steps to add OS/2 on this new Windows Vista Boot Manager? so after a 30 minutes research, I found a quick answer.

To be able to add OS/2 Warp 4.52 on you Vista Boot Manager you require the following:

  • Windows Vista (I used rel 6000)
  • OS/2 Warp 4.52 already installed on a HPFS partition of you HardDisk
  • Neosmart EasyBCD for Windows Vista (If you want to make you life easier)


1.- Boot Windows Vista and install EasyBCD.
2.- Double click Easy BCD icon to start it (on Windows Vista of course).
3.- Go to "Add/Remove Entries" from the buttons on your left. On this window you will see the entries installed on you Vista Boot Manager.

4.- On the section at the button of the window, select the "Linux/BSD" tag.
5.- On "Type" select "Grub" (don't worry if you don't have Grub installed)
6.- Put a name like "OS/2 Warp 4.52 Fix 5"
7.- Select the Hard Disk and Partition where OS/2 is installed. On my case is on the second partition of my primary hard disk (HDD=0, Partition=2)
8.- Click the "Add Entry" button.

That's all, when you reboot Windows Vista, now will see an option to choose the OS/2 partition.
