Bir terminal açmayı ve koşmayı deneyin
sudo chmod +x /etc/grub.d/20_memtest86+
sudo update-grub
Orada olup olmadığını kontrol et
grep memtest /boot/grub/grub.cfg
Yeni yaptığım gibi yaptım
hob@hob-HP-dx5150-MT:~$ cat /boot/grub/grub.cfg |grep memtest
hob@hob-HP-dx5150-MT:~$ sudo chmod +x /etc/grub.d/20_memtest86+

Orada değilse, bir terminalde nano kullanarak dosyayı oluşturmayı deneyebilirsiniz
sudo nano /etc/grub.d/20_memtest86+
veya bir gui editörü ile
gksudo gedit /etc/grub.d/20_memtest86+
Doldurun

Daha sonra chmod + x komutunu çalıştırdığınızdan emin olun.
Yine de eksik olduğundan biraz endişe duyarım - grubun içinde başka her şeyin var mı?
