I currently have three operating systems installed: WinXP, WinVista, and Red Flag Linux Desktop 6. Among them, WinXP and WinVista are installed on a 160GB SATA hard drive, while Linux is installed on a 40GB ATA hard drive. The multi-system boot uses the method of installing GRUB in the MBR. Now I can only boot XP and Vista in the GRUB menu, but I can't successfully boot the Linux on the other hard drive. I can only start Linux from the BIOS to adjust the Boot Menu. I want to ask if there are other boot management software that can boot the above three systems? If there are, please introduce them, thank you.
