About Mutli-OS boot up
I have installed Redhat Linux and Windows XP in my computer. I wanna to use GRUB to setup multi-boot. I was success before. Afterwards I have re-installed the Windows XP since it is not very stable after I installed too much softwares. After the re-installation, I try to setup multi-boot by GRUB again by invoke "grub-install /dev/hda3" in Linux, however, I still cannot features multi-boot again but just enter Windows. Anybody can teach me what should I do to enable multi-boot again?
