When I use USB flash memory (Ubuntu 14.04 amd64) for booting my PC (win 7 x64), I get the following error:
error: file '/grub/i386-pc/normal.mod' not found. grub rescue>
But using this USB flash memory on my laptop (win 7 x64), grub loads correctly.
I read these questions but they didn't help:
I removed the hard disc from PC, yet I get the above error, at boot time with USB.
My PC's BIOS settings has not two booting options; EFI or Legacy.
