Grub can be installed "on the disk" or "on a partition". You are installing it on a disk.
If you install it to a partition instead, you also have to "activate" that partition, and write "generic" code to the disk, ie, the mbr. That's what those two lines mean. But you are installing instead to the disk, to the MBR. Where you install must match what that file says.
hi boris, hi carlos, ok. think i have now understand for me only a little unclear why WAS it on my disk, with a standart tumbleweed new installation installed inside the sda1 partition and not inside the whole disk mbr? installation was done 2019 (if as i read "not recommended") and boris i found: https://github.com/arvidjaar/bootinfoscript "Current developer: Andrei Borzenkov" on a dos-mbr nvme system (not gpt) with grub and same 2019 installed tumbleweed on it: grub_installdevice has: /dev/nvme0n1p1 activate generic_mbr the script tells me: ==================================================================== Boot Info Script 0.78 [09 October 2019] ============================= Boot Info Summary: =============================== ============================ Drive/Partition Info: ============================= no valid partition table found "blkid" output: ________________________________________________________________ Device UUID TYPE LABEL /dev/nvme0n1p1 aa8cbef7-c727-4923-85ab-9e2b51f09328 ext4 ssd-system /dev/nvme0n1p2 a0a40027-0dd6-4d06-b391-f6b222a2f17d ext4 ssd-home ========= i guess after a short eye on the script you do not support nvme for analyse? simoN -- B e c h e r e r GmbH Sondermaschinenbau Mauermatten Strasse 22 79183 Waldkirch Germany Tel.: (+49) (0)7681 3134 Fax: (+49) (0)7681 4378 Mail: info@becherer.de Web: www.becherer.de USt-ID-Nr.: DE 814912198 Registergericht: Freiburg HRB 701860 Geschäftsführer: Dipl.-Ing.
