Sorry, is me again.
I encounter few problem while installing.
First of all, I got 5 partitions in my harddisk(HD onward).
I use partition magic format 2nd partition to ext3 and labelled it as "Linux FC2".
I use boot to install, at the beginning is ok.
Until Keyboard Configuration, i got a warning. That is:-
"Unable to align partition properly. This probably means that anoter partitioning tool generated an incorrect partition table, because it didn't have to correct BIOS gemetry. It is safe to ignore, but ignoring may cause (fixable) problems with some boot loaders."
So i jz click ignore, after that i use "Manually partition with Disk Druid".
After i selected the partition i formated to ext3, and click next.
The problem came out again. Thank is
"You have not defined a root partition(/), which is required for installation of Fedora Core to continue."
If someone know who to solve it, please kindly guild me. Thank you.
