Why kernel didn't show in GRUB menu?
1.In the internal disk is centos 5.0,
working ok (if only this disk, the kernel will show in GRUB menu, which you can choose to boot).
2.And then install redhat enterprise 5.0 on a external disk,
...choose a option (use GRUB and install MBR on sda1(the internal disk))...
3.Now when boot in to the GRUB menu, only can see the redhat kernel in the list, not centos. Use the internal disk is no problem , since I can mount it,but I just want it show in the GRUB menu...
Any one can give me a clue, what may cause this problem.
Thx in advance.
