I read installation guide, but it is rather brief! I don't want grub bootloader, which can damage Windows bootloader. I want to install elementary OS alongside Windows 10 and boot using f12! Is there a way to install it without grub? Or to choose partition, where grub will be installed. So after i delete linux partitions, Windows bootloader will still work. That is: i specifically don't want elementary OS bootloader saved in my Windows 10 EFI partition!
