Windows 10: Creating Recovery and EFI System Partition

Hello,I've just installed Windows 10 on my new SSD and formatted the HDD that had Windows 10 on it before. I just realized in Disk Management that the old HDD has the Recovery and EFI System Partitions. How would I go about adding those to the SSD instead?Thanks.

UNMOUNTABLE_BOOT_VOLUME after creating new EFI System Partition

I would probably have booted to a Windows install or recovery media to create the

EFI system partition by using Diskpart and the create par efi command with any modifiers necessary to make it fit in the correct location.

I know Linux can use a Microsoft EFI partition but I do know if Windows can use a Linux version.

Yes, the bcd listing which shows the boot manager and OS loader.

It may have been easier to use a third party partition manager to change the size of the EFI partition.

If you might need it, here are the details of an EFI partition from Diskpart.

How To: Create recovery partition.

it worked when i copied all the files of the disk to the recovery partition i created, but i had to use WinPE tab to add the entry.

Type: WIM Image (Ramdisk)
Name: Recovery
Path: Z:\Sources\boot.wim
and hit Add Entry
I tried it in VirtualBox and it worked.
At first, it would add a second "Windows 7" entry to the list, but when the installation is finished, the old one is deleted. (I formatted only C: partition)

 

How to install Win10 when the Recovery & EFI partitions were deleted?

There are a couple of issues with the above sequence. First, @drpeppercan stated that they already deleted the EFI system and recovery partition. So why is there a select part 1 and delete part override in the command sequence? What is being deleted? The Microsoft System Reserved partition? Hopefully there is an MSR partition there because if partition 1 is the Windows OS partition, then you just deleted Windows. And if there is an MSR partition there, why delete it?

Second, without a size specified when creating the EFI System Partition, it is just going to fill all available free space at the beginning of the drive. If there was a recovery partition, EFI System Partition and MSR partition, that free space is likely to be 600 MB is size, so you just created a 600 MB EFI System Partition that only needs to be 100 MB in size.

Without seeing the layout of the disk with: select disk 0, detail disk, list part you can't really suggest an accurate list of commands to rebuild the EFI system partition. It's only guessing.
