Install Centos from Grub

Generally, we install system with CD/DVD or on windows, only need to execute setup.exe, then follow the graphic steps.

Here I tried to install centos from disk storage, and make a note.

The old system on my computer is iSoft server 3.1 (from PuHua).

1. Make a verbose partition, mount it, in which put the Centos-xxxx.iso, images, vmlinz, initrd.img.

2. Reboot the old system, enter grub interface by enter C when rebooting.

3. In grub, execute commands as follow:

grub> kernel (hd0,5)/vmlinuz

grub> initrd (hd0,5)/initrd.img

grub> boot

kernel: load kernel, from the first disk, fifth partition.

initrd: load initrd.img

boot: booting

System would booting to install Centos.
