Does Enabling Mover Service Parttion Require A Reboot

TL; DR How do I create an EFI arrangement partition from scratch? How practise I put the EFI firmware on it onces it is created?

Long version

I hava Toshiba T430 laptop. I received information technology with Windows vii installed (just I recall originally it has shipped with Windows viii). I installed Ubuntu on it, just deleted some partitions on the disk so that I concluded up wiping out the Windows and only having Ubuntu. Among the deleted partitions was the EFI Organization partition. I discovered that Ubuntu now boots in Legacy mode (and not UEFI). I am trying to follow this guide on converting my Ubuntu installation from Legacy to UEFI. The problem - since there is no EFI partition whenever I choose from BIOS to boot using UEFI I cannot boot. That counts not but for the harddrive, but usb and DVD as well. I recall this is logical - information technology expects an EFI division and since it can't find it, it cannot continue booting futher, be it from HDD or DVD. So how do I recreate the EFI partition?

The guide to a higher place says:

Creating an EFI partition

If y'all are manually partitioning your disk in the Ubuntu installer, you demand to make sure you have an EFI partitioning set.

1. If your disk already contains an EFI partitioning (eg if your computer had Windows8 preinstalled), it can be used for Ubuntu too. Do not format information technology. It is strongly recommended to have only ane EFI partition per disk.

2. An EFI sectionalisation tin be created via a recent version of GParted (the Gparted version included in the 12.04 disk is OK), and must take the following attributes:

   1. Mount signal: /boot/efi (remark: no demand to prepare this mount point when using the manual partitioning, the Ubuntu installer will observe it automatically)

   2. Size: minimum 100Mib. 200MiB recommended.

   3. Blazon: FAT32

   4. Other: needs a "boot" flag.

I had some problem creating this partition:

• I boot from a alive Ubuntu DVD, open GParted, create a 200MB partition and format it to FAT32.
• In GParted I cannot gear up the mount point and thus cannot set the bootflag.
• I didn't set up the mountain signal in /etc/fstab since it's a live CD and fstab looked quite differently from what I expected compared to a normal boot. Anyway, I simply didn't know what values to set.

I booted again via the live DVD and then chose to install Ubuntu. I and then created a partition with the mentioned criteria - mount point, 200MB, FAT32, boot flag.

Still, I continue to take this problem and I suppose it's because on that partition there is no EFI firmware, it's simply an empty partition, which is suitable to take EFI firmware.

So again, how do I create an EFI partition, which has the EFI software, so that the laptop tin once more boot in UEFI mode?

SOLUTION Thank yous both for the answers. What I did was install Windows 8.1 from scratch by formatting the whole disk and and so installing (this fourth dimension properly) Ubuntu side by side to it. These are my partitions at present:

During the Win 8 setup, as soon equally I deleted all existing partitions and let Windows reformat the disk, it automatically created, besides the main install division, three additional partitions, namely one, 2, three. Now, afterwards I had a proper ESP, I could boot both from HDD or DVD in UEFI way.

You say that the ESP doesn't shop whatever info by default, simply I guess that when an Bone installs, information technology puts some info there. So I gauge my case was the following: I had wiped information technology out and even though I recreated information technology, it was not filled with any info, since the creation of the ESP was done after an Bone had been installed. I lost the Ubuntu installation (no big deal, information technology was a fresh install anyhow), but I guess that in order to salve it, I should accept followed grawity's advice. Didn't take fourth dimension, though, merely happily everything is fine now.
