How to recreate Recovery partition?

I converted my bios legacy booting windows 10 in UEFI boot, without reinstall OS, as the great user Tito suggested me some days ago. But I did a mistake accidentally deleting 450 MB recovery partition. Is there a way to re-create it without a clean install?

That works only for "Recovery image location", not for "Windows RE location" (450 MB Recovery partition).

 

boot with paragon hard disk manager( or other) and try to recover the delete partition

From the OP I'm thinking He's asking about the 450MB partition that's created when You upgrade. So if He's not planning on restoring to the earlier OS version I don't think it's needed ??

tell me if I am wrong, but the 450MB partition is created not only with upgrade, but also with clean install, and it helps when system doesn't boot for a failure, restoring system at actual (not earlier) OS version.

I obtained to recover WinRE, with REAgentC and following some tutorial, but not to reconstruct partition. Now, if I try to go in "create recovery disk" I haven't the chance to create a usb recovery disk

Thanks for posting the disk and partition layout details. The following assumes that WinRE.wim exists in C:\windows\system32\recovery and that you are running everything from an Administrator level Command Prompt. So make sure to adjust the locations to fit your situation.

Code:

DiskPart
Select disk 0
Select part 3
shrink minimum=450
Creat part primary
format quick fs=ntfs label="Recovery Tools"
assign letter="R"
set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
gpt attributes=0x8000000000000001
Exit
md R:\Recovery\WindowsRE
copy C:\Windows\System32\Recovery\winre.wim R:\Recovery\WindowsRE\winre.wim
C:\Windows\System32\reagentc.exe /setreimage /path R:\Recovery\WindowsRE /target C:\Windows
C:\Windows\System32\reagentc.exe /enable /target C:\Windows
Exit

 

Thank You agent268 . Made all the procedure and all is working, but only two adjustment:
1) before format must be typed command: "create partition primary"
2) I haven't a winre.wim in the C:\Windows\System32\Recovery\ directory and I got it from installation disk, after mounting install.wim.
Now I have got again my 450 MB recovery partition!
Not satisfied I am thinking to move it on my other hard disk...

 

Glad I could help. I added back the create part piece for future users that come across this. Thanks for catching that.
