Install syslinux's GPT MBR (Master Boot Record) to the root of MBR. This will sit in the 2048 of reserved space from when we partitioned the drive. | |||
<syntaxhighlight lang="bash"> | |||
dd if=/usr/lib/syslinux/bios/gptmbr.bin of=/dev/vda | |||
</syntaxhighlight> | |||
Prepare the /boot folder with syslinux's modules. The .c32 files that ship with syslinux are for systems that use a bios to boot. Symlink the bios modules into syslinux's boot folder. | |||
<syntaxhighlight lang="bash"> | <syntaxhighlight lang="bash"> | ||
ln -s /usr/lib/syslinux/bios/*.c32 /boot/syslinux/ | |||

<syntaxhighlight lang="bash"> | <syntaxhighlight lang="bash"> | ||
extlinux --install /boot/syslinux | extlinux --install /boot/syslinux | ||

By default, syslinux tries to boot /dev/sda3. Change it to boot /dev/vda1 | |||
<syntaxhighlight lang="bash"> | <syntaxhighlight lang="bash"> | ||
sed -i 's#/dev/sda3#/dev/vda1#' /boot/syslinux/syslinux.cfg | |||

arch-chroot /mnt | |||
</syntaxhighlight> | </syntaxhighlight> | ||
Once you are back in the Arch environment, Check the following: | |||
