Hello, I'm posting this here, since I've sent a message to the ChaletOS team and I don't get a response. I've spent several hours googling but I haven't found a solution.
I installed ChaletOS 16.04 from a USB stick in a new partition I created (*) (I also created a swap partition). When the installation finished and rebooted, I was directly sent to the grub rescue shell, with this message: "error: unknown filesystem". After investigating, I realized that the "root" and "prefix" grub variables were pointing to the wrong partition. The steps I followed were these:
1) set root=(hd0,msdos2)/ -> When issuing the command: "ls (hd0,msdos2)/" it shows the linux root, so I know it's the correct partition.
2) set prefix=(hd0,msdos2)/boot/grub/i386-pc -> here is where I found all the .mod grub files where at.
3) insmod normal -> This is where the problem is. I get this error: symbol not found: 'grub_divmod64'.
All the answers I've found to this problem said I should boot from a live CD (or USB) and reinstall grub, but the thing is I can't even do that. My BIOS boot priority is correctly configured to boot from my USB stick first (it's a netbook, I don't have a CD drive), still, "grub rescue" is the first thing I see, and I can't get out of it.
I'm completely locked outside of my computer and about to cry. Does anybody know how to solve this? :'(
Thanks in advance!
PD: (*) extra info just in case it's relevant: Before this whole thing, I had 3 partitions:
1) Linux Mint 13
2) a broken Windows 7
3) fat32 partition for data in general
To install ChaletOS I erased the first 2 partitions, and created a new one for ChaletOS and a swap partition too.

After that it let me boot from my USB stick with a SuperGrub live version, from which I was able to boot my Chalet installation. Then I ran the following commands:
