I want to install eOS but i already have an Arch install with grub2. Can i skip eOS's grub installation and use my existing one?
I would suggest you to install grub to the partition where you install your eos. You can select grub partition while partitioning your hdd.
Then update your grub from Arch Linux using
sudo update-grub. (Then hide your eos grub if needed)
To install elementary OS without installing the GRUB boot loader:
- Boot up an installation media an select "Try elementary OS". This will load a live session instead of loading the installer directly.
Open Terminal and enter the following command. This will launch the installer with the option to not install the boot loader:
Continue installation as normal. The GRUB boot loader will not be installed.
I went ahead and installed it anyways. When prompted to select the location for the bootloader I went with the same drive I'm installing to, which had Arch and grub2 in it. The installation went well, and the previous grub2 was replaced, leaving me with all my old boot options with the addition of eOS.
