It should be a Grub menu that allow to choose between different OS or
kernel (if you have more than one installed), and it
should automatically boot the default option after a few seconds timeout.
Assuming with 'grub prompt' you mean the command line provided by Grub,
yes, something went wrong.
Do you choose a GPT or MBR layout? installing grub for GPT in MBR or vice
versa may cause this; there is also a bad bug that
is hitting stable systems (at least in Debian) this way, but you should
read a 'symbol error' or something before the prompt

Anyway, since you get the prompt, I suggest to try to boot from there and
then reinstall Grub.

example:

>ls (should give a list of disks, like hd0 hd1 and partition, like
(hd0,msdos1)

try to find out which partition is the devuan root, for example

>ls (hd0,msdos1)/      (try each partition untill you get a list of root

subdirectories)

then do (assuming hd0,msdos1 is your root)

>set root=(hd0,msdos1)
>linux /boot/vmlinuz-[ full name of the image,use TAB for autocompletion ]
root=/dev/sda1
>initrd /boot/initrd.img-[use TAB, same version as the vmlinuz]
>boot

I can't give you exact comands since I don't know your disks layout and
names of installed kernels
