Installation using EFI
It is possible to get noop running on an EFI system, it's just a little tricky at the moment.
The basic steps are:
- Partition drive ( most likely GPT format )
Here's a super quick reference that will give you a 32 MB EFI partition, and the rest root:
mkpart primary fat32 0 32
mkpart primary ext4 32 <insert whatever total size of drive is eg. 107G>
The idea is you need a separate partition at the beginning for EFI binaries.
- Mount hard drive and install as you normally would, but you also need to mount efi partition as well in /boot/efi
Note: sda1 is EFI partition, sda2 is root partition
mount /dev/sda2 /root/hdd
mkdir -p /root/hdd/boot/efi
mount /dev/sda1 /root/hdd/boot/efi
wget nooplinux.org/noop/instlr && chmod +x instlr
- Install bootloader (grub 2)
Make sure efibootmgr is installed, if not then: pkgr -i efibootmgr
and then run something like:
grub-install --target=x86_64-efi --efi-directory=/boot/efi
This should add grub as an entry in EFI, if it does not you will need to do this manually usually using an EFI shell.
- Change grub.conf
Add efi modules:
Next, you will need to change the root drive that grub is looking for. The file is at /boot/grub/grub.cfg.
You will need to change it to something like:
as well as root=/dev/sda1 to sda2 probably ( gpt2...sda2...should make sense :D )
If you're not sure you can boot into grub's command line mode and type ls to view partitions.
- Lastly, change fstab to reflect changes
- Virtualbox's EFI settings dissapear
This is a known bug: https://www.virtualbox.org/ticket/11177
Workaround is creating a file in the EFI partition called startup.nsh.
Inside it, it will point to grub's .efi file.
- X wont start
For some reason X needs a config file in some cases, when you get to the shell log in as root and try:
cp xorg.conf.new /etc/xorg.conf
then restart the display manager, like:
systemctl restart kdm
