Get out of GRUB Rescue Mode

Hi guys,

I have installed Arch Linux recently. However  I  faced  low  space  issues  in root   directory and   I   copied    root     directory into     a       new     ext4    partition.
This was my only option  because  I   did  nt   have  any   space   near   my   root    partition(It   is   somewhere    in the    middle   of 5    partitions).    Then    i used to chroot  command  and  set   that   partition   as   root(/)  .   Now   I    always  get   this   GRUB   rescue   mode    and    I    should    always    type   

set prefix=(hd0,gpt8)
set boot=(hd0,gpt8)/boot/grub
insmod normal
normal

Only  then  I get  the GRUB menu. 

Can you help me fix this problem?

Thanks in  advance!!

Re: Get out of GRUB Rescue Mode

You need to re-run the grub-install command, since it needs to embed the location of "set root=(hd0,gpt8)" in order to locate the grub.cfg and read the additional configuration.

By the way, you have just learned why overly elaborate partition layouts are a bad idea. If you really want many partitions, use something like lvm which allows you to conveniently resize them when you need to -- otherwise, just use one partition.

There's no practical use of multiple partitions for one OS that I can think of, which are not solved *better* by the use of a filesystem which supports subvolumes (e.g. btrfs). And in most cases, there's no need for multiple partitions at all. (I wish people would stop making silly /boot partitions for example.)
