I have three storage devices:
⠀/dev/sda/, an SSD with Windows 8 installed on it (NTFS)
⠀/dev/sdb/, an HDD with a single NTFS partition on it that is shared
⠀/dev/sdc/, an SSD with Ubuntu 13.10 installed on it as a single EXT4 partition
About 50% of the time when I reboot, usually to switch the OS, I see the following:
error: no such device: <uuid> entering rescue mode... grub rescue>
<uuid> is the UUID of /dev/sdc1. When it happens, it goes away if I press Ctrl+Alt+Del and go into my BIOS's boot menu and choose /dev/sda to boot from.
The intermittent behavior and the fact that it goes away only through that method (i.e. reinstalling GRUB to /dev/sda as other Ask Ubuntu answers recommend does not help) makes me think this is unrelated to the dozens of other AU questions about the same error message. What can I do to resolve this?
