Arch Installation

arch-install

* Partitioning
 $ cfdisk
 Considering:
  * Primary partition 100M boot
  * Primary partition 20000M /
  * Primary partition -everything else- /home
  * Logical partition 1024 swap (1G, Depending of the amount of RAM)

* Creating filesystem
 * boot
  $ mkfs.ext2 /dev/sda1
 * root
  $ mkfs.ext4 /dev/sda2
 * home
  $ mkfs.ext4 /dev/sda4
 * swap
  $ mkswap /dev/sda5

* Mounting
 $ mount /dev/sda2 /mnt
 $ mkdir -p /mnt/home /mnt/boot
 $ mount /dev/sda1 boot
 & mount /dev/sda4 home
 $ swapon /dev/sda5

* Internet
 $ wifi-menu
 or
 $ dhcpcd eth0

* Installing base system
 $ pacstrap /mnt base base-devel

* GRUB for BIOS
 $ arch-chroot /mnt pacman -S grub-bios

* Configure the system 
 $ genfstab -p /mnt >> /mnt/etc/fstab
 $ arch-chroot /mnt
 $ echo "<hostname>" > /etc/hostname
 $ ln -s /usr/share/zoneinfo/America/Santiago /etc/localtime
 $ echo "LANG=\"en_US.UTF-8\"" > /etc/locale.conf
 $ echo "LC_COLLATE=\"C\"" >> /etc/locale.conf
 $ echo "LC_TIME=\"en_US.UTF-8\"" >> /etc/locale.conf
 $ sed 's/#en_US/en_US/g' -i /etc/locale.gen
 $ locale-gen
 $ mkinitcpio -p linux

* Configuring GRUB
 # modprobe dm-mod (NOT anymore!)
 # grub-install --target=i386-pc --recheck --debug /dev/sda
 # mkdir -p /boot/grub/locale
 # cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo

 * If you have windows installed, you need to add an entry to the grub.
  * First mount your windows partition
   # mount /dev/sdXY /mnt
  * Then, get the uuid
   # grub-probe --target=fs_uuid /mnt/bootmgr
  * Copy the previous number to the following line (replace THE_UUID)
   # echo "menuentry "Microsoft Windows Vista/7/8 BIOS-MBR" { 
    insmod part_msdos
    insmod ntfs
    insmod search_fs_uuid
    insmod ntldr     
    search --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 THE_UUID
    ntldr /bootmgr
    }" >> /etc/grub.d/40_custom

 * Final step
  # grub-mkconfig -o /boot/grub/grub.cfg

* Final steps
 # passwd
 # exit
 # umount /mnt/boot
 # umount /mnt/home
 # umount /mnt
 # reboot
