My computer has two hard disks. Select grub to install it on mbr. After the installation is complete, I will prompt you to restart and then the following will appear:
GRUB Loading Stage1.5
GRUB Loading, please wait ......
Error 21
Only the mbr can be rebuilt to enter Windows.
I installed several systems like this, from fedora10 to fedora11 beta, as well as CentOS5.3 and openSUSE11.1. The most strange thing is that when CentOS5.3 is installed, at the beginning, I stopped at loading ahci driver ...... After a long time, the graphic interface came out. When the partition editing was installed, the system prompts that the hard disk could not be found, but I also solved this problem.
I think Error 21 means that the specified partition cannot be found, that is, grub cannot find the hard disk. I can use Grub For DOS to guide the Linux system, but it feels a little troublesome and not as convenient as Grub on mbr.
My previous PC does not have this problem. Recently I changed one, and this problem occurs. My configuration is as follows:
Motherboard: vodplus AF720T V20
CPU: AMD black box 7750
Memory: Kingston DDR2 2 GB
Hard drive: GB west, GB Seagate
