Installation • Re: GRUB and System - on different disks (on computer with BIOS)?

Hello,

My main question is - will the MBR of the disk with the system remain free from Boot system records, when booting from Grub from another disk, on a system with BIOS. Of course, I can practically check this, but maybe someone will tell me the details...

The MBR (Master Boot Record) of a hard disk remains free of boot system records as long as you don't write a boot loader to it: this is true for systems configured to boot in legacy boot/CSM mode.

The disk's MBR is not used by systems configured to boot in UEFI mode, because UEFI uses the boot disk's ESP (EFI System Partition) and the motherboard's NVM (Not Volatile Memory).

Hope this helps.
