When trying to install Xubuntu 13.10, it always stops at
xubuntu ubiquity: Setting up grub-efi-amd64-signed (1.22.1+2.00-19ubuntu2.1) ...
It's just stuck there. Nothing is happening, although I can continue to use the USB live mode as I am typing this post right. I am installing from a USB drive booted into UEFI because I want to dual-boot with Win 7 Pro x64, so switching to Legacy BIOS mode is out of the question unfortunately. I don't have any encrypted partition or drive.
Does anyone have any pointers how I could overcome this?
