Hi I have a question for you I have a healthy efi partition in front of my 500 gig ssd which isn't 500gigs anymore it's 465.65 gb NTFS I had a system recovery partition and that was unallocated disk space. Of 4.99mb So i put my windows 10 creators update in my cdrom and restored windows and the unallocated rcovery partition was gone. Which is what I want that disk space has returned to my primary c drive the one that windows is on.
Now I have a Healthy EFI Partition and I'm wondering first what's on that partition? It was created with Windows so I'm assuming it has the boot files on there, but I'm not sure.
What Is EFI System Partition (UEFI + GPT) Further reading: deleting a partition in Windows just clears or modifies corresponding partition information in partition table, making Windows unable to locate the partition, and the actual partition still reside in its place until new partition is created there. Windows 10 Diskpart Extend Volume. Diskpart is a powerful partition manger built in all Windows operating system, so you can run Diskpart command to extend volume in Windows 10. As a powerful Windows built-in partition management tool, you can run Diskpart command to manage hard drive including create partition, delete partition.
Let me ask you If I deleted that partition using disk part in the command prompt and I restarted windows I wouldn't be able to get back into windows right? Because the boot files are on that efi partition that I just deleted right? And they are not on the partition that has windows installed right? I probably won't do this but it's still a good thing to know I was wondering if anyone could tell me how to delete that Partition in windows or anywhere else for that matter. And then merge that unallocated space with the boot files back to the c drive so I will be ale to boot back into windows? And then I wont have the windows boot manager in the bios anymore I will just be able to boot straight from the ssd.
Which will be faster boot. I know how to delete it, it but do not know how to merge that space back to the c drive so the boot files will now be on the c drive thanks a lot!! A drive that is '500GB' is actually reported by Windows as 465GB. This is normal and to be expected. The EFI partition is indeed your boot partition. Delete that, and no boot for you.
It's supposed to be its own partition, not 'part of' the C. Please show us a screencap of your Disk Management window. Hi, Yes could you tell me how to do a screen shot On here? I know how to set it up in windows it's just that there is something special that I have to do on here is all. As for the efi partition. I knew that there were boot files on the efi partition I have seen you tube videos on how to delete it, but have not seen how to extend the c partition and merge that Unallocated disk space back to the c drive so that the boot files are on the c drive. So that I can boot straight from the ssd and not be booting from that other partition not using the windows boot manager.
What I will do is create a.txt file and copy and paste your instructions on how to send the screenshot through here. Thank you so much for your time and help!!

Thank you so much for your time and help!! Detailed instructions on posting images on Tom's hardware. Basically, capture the screen. Upload to somewhere like imgur.com. Post the link here. Now I know this is only 100mb in size but I would still like to know how to do this. I know how to delete it and turn it into unallocated disk space but I should be able to then merge the space back to the c drive and transfer the boot files to it.
Or I transfer the boot files first. Then I would delete the partition and turn it into unallocated disk space. I think once it's unallocated disk space the boot files are gone so I would have to transfer them to the primary windows drive first. No, you do NOT do it.
Sure, you can format that partition and potentially merge it into the large 465.65GB partition. And if you do that, your system WILL NOT BOOT. Leave it as it is.
It is supposed to be there. Or, you can continue down this road, and then come back here later asking how to get your PC to boot up. Now I know this is only 100mb in size but I would still like to know how to do this.

I appreciate it!!
Contents. Check for an existing partition If you are installing Arch Linux on an UEFI-capable computer with an installed operating system, like 10 for example, it is very likely that you already have an EFI system partition. To find out the disk partition scheme and the system partition, use as root on the disk you want to boot from: # fdisk -l /dev/sd x The command returns:. The disk's partition table: it indicates Disklabel type: gpt if the partition table is or Disklabel type: dos if it is. The list of partitions on the disk: Look for the EFI system partition in the list, it is a small (usually about 100–550 MiB) partition with a type EFI System or EFI (FAT-12/16/32).
To confirm this is the ESP, it and check whether it contains a directory named EFI, if it does this is definitely the ESP. Note: It is recommended to use for UEFI boot, because some UEFI firmwares do not allow UEFI/MBR boot. To avoid potential problems with some UEFI implementations, the ESP should be formatted with FAT32 and the size should be at least 512 MiB. 550 MiB is recommended to avoid MiB/MB confusion and accidentally creating FAT16, although larger sizes are fine. According to a Microsoft note, the minimum size for the EFI system partition (ESP) would be 100 MiB, though this is not stated in the UEFI Specification. Note that for 4K Native drives (4-KiB-per-sector) drives, the size is at least 256 MiB, because it is the minimum partition size of FAT32 drives (calculated as sector size (4KiB) x 65527 = 256 MiB), due to a limitation of the FAT32 file format. GPT partitioned disks EFI system partition on a is identified by the C12A7328-F81F-11D2-BA4B-00A0C93EC93B.
Choose one of the following methods to create an ESP for a GPT partitioned disk:.: Create a partition with partition type EFI System.: Create a partition with partition type EF00.: Create a partition with fat32 as the file system type and set the esp flag on it. Proceed to section below. MBR partitioned disks EFI system partition on a partition table is identified by the EF. Choose one of the following methods to create an ESP for a MBR partitioned disk:.: Create a primary partition with partition type EFI (FAT-12/16/32).: Create a primary partition with fat32 as the file system type and set the esp flag on it.
Proceed to section below. Format the partition After creating the ESP, you must it as. To use the mkfs.fat utility,. # mkfs.fat -F32 /dev/sd xY If you get the message WARNING: Not enough clusters for a 32 bit FAT!, reduce cluster size with mkfs.fat -s2 -F32. Or -s1; otherwise the partition may be unreadable by UEFI. See for supported cluster sizes.
Mount the partition The kernels, initramfs files, and, in most cases, the processor's, need to be accessible by the or UEFI itself to successfully boot the system. Thus if you want to keep the setup simple, your boot loader choice limits the available mount points for EFI system partition.
The simplest scenarios for mounting EFI system partition are:. ESP to /efi and use a which has a driver for your root file system (eg., ). ESP to /boot. This is the preferred method when directly booting a kernel from UEFI. Tip:. /efi is a replacement for the previously popular (and possibly still used by other Linux distributions) ESP mountpoint /boot/efi.
The /efi directory is not available by default, you will need to first create it with before mounting the ESP to it. Alternative mount points If you do not use one of the simple methods from, you will need to copy your boot files to ESP (referred to hereafter as esp). # mkdir -p esp/EFI/arch # cp -a /boot/vmlinuz-linux esp/EFI/arch/ # cp -a /boot/initramfs-linux.img esp/EFI/arch/ # cp -a /boot/initramfs-linux-fallback.img esp/EFI/arch/. Note: If ESP is not mounted to /boot, make sure to not rely on the (including that of ). Always have it mounted manually prior to the any system or kernel update, otherwise you may not be able to mount it after the update, locking you in the currently running kernel with no ability to update the copy of kernel on ESP.
Alternatively, e.g.: /etc/modules-load.d/vfat.conf vfat nlscp437 nlsiso8859-1 Using bind mount Instead of mounting the ESP itself to /boot, you can mount a directory of the ESP to /boot using a bind (see ). This allows to update the kernel directly while keeping the ESP organized to your liking. Note:. This requires a and compatible with FAT32.

This is not an issue for a regular Arch install, but could be problematic for other distributions (namely those that require symlinks in /boot/). See the forum post. You must use the root= in order to boot using this method.

Just like in, copy all boot files to a directory on your ESP, but mount the ESP outside /boot. Then bind mount the directory: # mount -bind esp/EFI/arch /boot After verifying success, edit your to make the changes persistent: /etc/fstab esp/EFI/arch /boot none defaults,bind 0 0 Using systemd features event triggered tasks. In this particular case, the ability to detect a change in path is used to sync the EFISTUB kernel and initramfs files when they are updated in /boot/. The file watched for changes is initramfs-linux-fallback.img since this is the last file built by mkinitcpio, to make sure all files have been built before starting the copy. Tip: For with your own keys, you can set up the service to also sign the image using: ExecStart=/usr/bin/sbsign -key /path/to/db.key -cert /path/to/db.crt -output esp/EFI/arch/vmlinuz-linux /boot/vmlinuz-linux Using filesystem events can be used to run a script syncing the EFISTUB Kernel after kernel updates. An example with follows. /usr/local/bin/efistub-update #!/bin/sh cp -af /boot/vmlinuz-linux esp/EFI/arch/ cp -af /boot/initramfs-linux.img esp/EFI/arch/ cp -af /boot/initramfs-linux-fallback.img esp/EFI/arch/.
