pls suggest which device to select for grub-pc
by nirvaanr from LinuxQuestions.org on (#5E4F6)
Hi
On my Debian 10 Server, when I ran "apt -y install gnupg2 software-properties-common" it popped-up a menu with "congiruing grub-pc" asking where to install Grub. I have no idea if it's MBR or /boot and also I have RAID-0 of 4 disks.
