GRUB Loading stage1.5 > Error 15 - no boot menu, no nothing
Today I restarted my laptop and got this message.
I'm quite new to Arch and Linux (switched from win7 about 2 months ago) in general and really don't know what to do now 
The exact message I'm getting is:
GRUB Loading stage1.5
GRUB loading, please wait...
Error 15currently I'm using an Ubuntu live-usb stick to get into my machine.
this is my output of fdisk -l

Re: GRUB Loading stage1.5 > Error 15 - no boot menu, no nothing
I suppose your boot partition is sda1. You have to mount it in order to find your menu.lst. (sudo mkdir /mnt/boot && sudo mount /dev/sda1 /mnt/boot)
I think that the fstab you pasted is the one from your Ubuntu live USB stick, not the one from your hard drive. (Although it contains a reference to sda2, but I guess this has been automatically generated...?)
You must have done something to break Grub (changed the partition order or deleted a file or modified your menu.lst and set the wrong device for your boot partition.) There is plenty of documentation about the error 15 problem and how to fix it on the web.

Re: GRUB Loading stage1.5 > Error 15 - no boot menu, no nothing
So the last thing I did was to to a "pacman -Syu" ..all went well there (can't remember tho what exactly was updated)
Never did any changes to my partition order or touched menu.lst (all should be on "default" settings I think, since I installed Arch with the "auto-installer" and all default settings for the partitions.
I just tried to mount my sda1 again (which is my boot partition), but it seems like it's empty

Re: GRUB Loading stage1.5 > Error 15 - no boot menu, no nothing
To know what was updated, look at /var/log/pacman.log.
If your boot partition (or directory) is empty, obviously grub won't work. You could mount your root partition and see if there's a boot directory in there. If there is none then grub files (and your kernel) have been deleted somehow. I don't remember reading about something like that.
When you run "ls -la /boot/grub/" you're listing the contents of your USB stick, which doesn't matter when you're trying to make your hard disk installation work...
