I'm a new Ubuntu user.
I have UEFI system and after few tries I succeeded to install (via usb), the latest version of ubuntu.
Now when I'm trying to boot from grub i get this message:
an error occurred while mounting /boot/efi
what can i do?
Type the following commands:
The first command will return information on the EFI System Partition (ESP), as recorded in your

Another possible problem won't show up as a discrepancy in the analysis you've just performed, since it's a matter of a filesystem needing repair. You can do this with the
You must pass it the device filename associated with the ESP --
One more point along these lines: If you're dual-booting with Windows 8, it includes a "fast startup" feature that is basically just a suspend-to-disk feature. Sharing partitions between Windows and Linux with this feature active is almost certain to lead to problems, and I've heard of the ESP being affected by this. Thus, if you're dual-booting with Windows 8, you should disable the fast startup feature. This page describes how to do this in detail.
I was completely lazy and booted a Ubuntu live disk..... once the disk loaded up a desktop, I ran GParted.. I saw that my boot partition /dev/sda1 ext4 with a mount point / had a uuid that looked like a hardware uuid 5465465406546506540d546sd54f66 something like that. (that was a clue to me that.. this was the damaged portion when i had to hard boot when my machine locked up).. I right clicked on said partition made sure it was unmounted and selected check.... thus gparted checked and repaired the partition..... restarted and everything loaded up great... I'm sure it wont work for all cases but it worked for me
