Thread: how regenerate grub.cfg for only one, specified hdd?

hello all
have copied system new hdd. generate new grub.cfg file grub-mkconfig file should contain _only_ entries new hdd. when try generates entries both bootable disk (current , new) new 1 there no memtest entries.
generate same entries have current disk referencing partition(s) on new one.
should manually? isn't there automated method?

, second one:
i'm suprised there no "grub" program own simple shell when grub2 installed. replaced sth?

best regards

can see additional entries generated new hdd have root set old 1 - complete nonsense

code:

menuentry "ubuntu, linux 2.6.35-28-generic (on /dev/sdb3)" {     insmod part_msdos     insmod ext2     set root='(hd1,msdos3)'     search --no-floppy --fs-uuid --set 6a26581f-084b-42e4-89dc-71b464b6b29c     linux /boot/vmlinuz-2.6.35-28-generic root=uuid=415d9dc0-150c-404c-ba6f-704c40a71846 ro quiet splash     initrd /boot/initrd.img-2.6.35-28-generic }

uuid 6a2... - partition on new disk
uuid 415... - partition on current disk

did full partition copy dd or gparted , not copy files partitions created in advance. may have duplicate uuids.
booting new drive using old / (root).

post can see entire configuration.
