I was rebuilding my home print server (a re-purposed ASUS eepc netbook) yesterday and was trying Debian 7.5 netinst from a USB stick.
All was going well until partway through it complained about not having an installable kernel available to intstall. I continued on through the process and sure enough at the end the reboot stalled at grub due to no kernel entries.
More of a curiosity really as I resolved it using the Live-DVD downloaded onto the USB stick. I was a) trying it out and b) looking for a minimal installation.
