NOTE:This is a bit risky and I take no responsibility if it doesn't work for you!

You must have Windows XP and BeOS installed on different partitions on the bootdisk. This may or may not work if BeOS is located on a seperate disk. It's up to you if you want to try.

1. Start Windows XP
2. Select Start -> Run
3. Type in cmd and click Ok
4. Type diskpart and hit ENTER
5. Type list volume and hit ENTER
6. A listing of volumes on all your disks should appear
   Sample (Swedish Windows XP):
   

   DISKPART> list volume
   
     Volymnr.    Enh  Etikett      Fils.  Typ         Storlek  Status     Info
     ----------  ---  -----------  -----  ----------  -------  ---------  --------
     Volym 0      E   rtcw         CDFS   DVD-ROM      661 MB
     Volym 1      C                NTFS   Partition   6659 MB  Felfri     Systemst
     Volym 2      D   WIN98 2      FAT32  Partition   6460 MB  Felfri
     Volym 3                              Partition   6453 MB  Felfri
     Volym 4                              Partition   2059 MB  Felfri
   

7. Find the volume that is your BeOS-volume. Normally it should not have a letter, name or filesystem specified
8. Use the volume number instead of the italic text and type select volume BeOS-volume number and hit ENTER
   Sample: 'select volume 3'
9. CAUTION: Be 100% sure that this is your bootable BeOS-volume
10. The next step will make BeOS boot instead of Windows XP. If anything goes wrong your system can become unbootable so make sure you know how to fix the boot record if you mess up
11. Type active and hit ENTER
12. When you reboot BeOS should load instead of WIndows XP
13. Install bootman
14. When you reboot bootman should help you select the OS to boot

Good Luck,
