Thank you for the replyment!
Although the handbook I gived describes what I did, I can still summerize it in short. So you guys can save time.
What I did:
fdisk to Partition, activated the Swap Partition, Mount, download, unpack stage files, configure compile options, chroot to the new Environment, configure portage, the kernel, modules, system (/etc/fstab), network information, locales, installed system tools(syslog-ng, Cron Daemon, mlocate), file system tools, (emerge reiserfsprogs and emerge e2fsprogs), bootloader(grub). And the last step, rebooting the system using exit command. The system freeze up.
Let's see if these info helps, I can go more in detail if you want.
