Can't remove grub entries

fredmyra · 2 March 2022 04:00

I run 5.10.102-1-MANJARO as the bootloader master on a Fujitsu i5 Lifebook, multibootc setup, as per lsblk output:

lsblk -o NAME,LABEL,PTTYPE,FSTYPE 

NAME    LABEL       PTTYPE FSTYPE
sda                 dos

├─sda2  my_Data     dos    ext4
└─sda3              dos    ntfs

Obs.: sda was made inactive when when typed “a” instead of “b” when copying the content of some data partition. It was a pure windows disk which I seldom use, so I still haven’t found the time to reinstall it, after a couple months.
Everything works fine with “/dev/sdb” but I have had a minor problem all the time with my grub menu : at boot Grub displays a long list of entries which exist neither in “/boot/grub/grub.cfg” nor in “/etc/grub.d/40_custom”, nor in any place I know or can think of.

My grub.cfg contains:

I have tried several solutions deemed satisfactory in google results without success. Today I reinstalled grub and then once again carefully followed the instructions at https://wiki.manjaro.org/index.php/GRUB/Restore_the_GRUB_Bootloader but those entries are still there - i am enclosing 2 views of the extra entries.

grub_menu_1
grub_menu_2

As for my "/etc/grub.d/40_custom:

nano  /etc/grub.d/40_custom

GNU nano 6.2                                 /etc/grub.d/40_custom                                         
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the

# the 'exec tail' line above.
menuentry 'TCE frugal'{
     insmod part_gpt
     insmod ext2
     set root=(hd0,gpt2)
     linux /tce/boot/vmlinuz64 vga=791 lang=sv_SE.UTF-8 kmap=qwerty/latin1.kmap tce=sdb2 restore=sdb2 deskto>
     initrd /tce/boot/corepure64.gz
}

Will be grateful for any hints !

I beg your pardon for having jammed your server. Immediately upon posting it stroke me that in my 10 years of daily multibooting I ONCE resorted to editing a “custom.cfg”. That was the prolem.

I have noticed that writing a post often helps me sorting out problems. Sometimes I don’t even get to th point of posting.
After this I will try to follow a policy of letting posts “mature” before actually posting them. It will certainly be a matter of coping with the stress of finding a solution. Thanks for a great forum !
