Since you're talking about Ubuntu, I'm going to assume you use that. To fix, do the following: first, ensure you're working on the installed system, not the live system. A live image usually has its own root filesystem that makes reinstalling grub harder than it could be. Assuming you mount your installed root filesystem on /mnt, you can do this by ...

The kernel in modern Linux setups is heavily module based, i.e., the kernel proper (loaded on boot into RAM) includes just the bare minimum functionality, all the rest is compiled as modules (loadable at runtime). To make this work even when e.g. the devices or filesystems required for boot are modules, an initramfs is loaded with the kernel (as the name ...

The entire kernel is loaded into memory at boot, typically along with an initramfs nowadays. (It is still possible to set up a system to boot without an initramfs but that's unusual on desktops and servers.) The initramfs's role is to provide the functionality needed to mount the "real" filesystems and continue booting the system. That involves kernel ...

The entire kernel (but not its modules) will be loaded into memory. If there are modules which the kernel will need before any filesystems are available (this usually means the drivers for the filesystems and their devices), then those modules will be in the initramfs (in memory), and the kernel will load them from there. Other modules can be loaded later ...

You can get back fedora. I encountered this issue on my laptop computer each time when the grub2-efi package updated/reinstalled (including system upgraded to next release). It will caused grub2 boot into some kinds of rescue mode like yours. The grub2-efi package from Fedora seems can't install correctly on my laptop (ASUS TX300, Fedora x86_64, version 18 ...

GRUB doesn't know that you've removed /boot. During the boot process GRUB loads long before the kernel and always has to figure out what's going on without the convenience of things like mounted filesystems. When you install GRUB it's told where (as in the BIOS or EFI partition) to find it's config file. It isn't until long after GRUB has handed off to ...

Boot completly from live cd (do not boot from hard drive!) and mount your hard drive to /mnt dir. First of all check out path to vesamenu\menu files in your syslinux.cfg. Cfg file must be somewhere like /boot/syslinux/syslinux.cfg. You should see something like DEFAULT menu.c32 or UI menu.c32 or vesamenu, it doesn't matter right now. If you dont see one of ...
