Arch Linux - Grub error

I'm trying to install Arch and I'm stuck at the following command:

Code:

grub-mkconfig -o /boot/grub/grub.cfg

Which gives me the following error.

Code:

Error: out of memory

Error: syntax error

Error: incorrect command

Error: syntax error

Syntax error at line 150

Syntax error are detected in generated grub file.

Ensure that there are no errors in /etc/default/grub and /etc/grub.d/* files or please file a bug report with /boot/grub/grub.cfg/new file attached.

Following a thread on ArchLinux's forums I can see that it might not get fixed soon https://bbs.archlinux.org/viewtopic....58176#p1358176

So, people are suggesting that we add the following lines to /etc/default/grub:

Code:

GRUB_DISABLE_SUBMENU=y

What could happen with that line of code? What side effects? What about after the grub is updated?

Grub Legacy and earlier releases of Grub2 had a menu in grub.cfg. The newer Grub2 has sub-menus under the main menu in some cases and changing your entry as suggested in /etc/default/grub would eliminate sub-menus and leave you with just one menu.

After updating Grub, the change would persist if you have this entry in /etc/default/grub.

I'm not really sure of the reasoning behind sub-menus, nor its advantages and disadvantages.
You forgot to post what is actually on line 150, the reported error line. I'm guessing it is: {

That depends on which file we're talking about.

I use syslinux IMHO it's simpler but seems to update more than GRUB.
