Windows 10 lacks partitions and WinRe options

I have just installed a fresh windows 10 v1909. Having installed some apps, I activated bitlocker. Bitlocker warned me saying "something" about a recovery partition not existing and how it can be made manually if needed. When I went to disk manager there indeed was no recovery partition and all of my advanced startup options were reduced to boot options. No command prompt, no restore points... How do I remake a recovery partition that windows usually automatically creates and how do I return all of the options to WinRe/Advanced startup? Edit: I would also like to add that the System reserved partition no longer exists and the one from which windows boots is unnamed.

PCs with BIOS motherboards are often configured without a WinRE partition, instead storing WinRE on the Boot or OS partition (WinRE should always be on its own partition).

To move WinRE to its own partition: (ReAgentC)

1. Open an Admin Terminal: WinKey+R > Open: powershell > CTRL+SHIFT OK

2. Backup current WinRE.wim:

   1. Verify if C:\Windows\System32\Recovery\WinRE.wim exists:

      ls "C:\Windows\System32\Recovery" | FindStr /I "WinRE.wim" ; ls "C:\Windows\System32\Recovery" -Hidden | FindStr /I "WinRE.wim"
      

   2. If it doesn't:

      Xcopy /H "C:\Recovery\WindowsRE\WinRE.wim" "C:\Windows\System32\Recovery"
      

      • BIOS: May store WinRE on Boot partition: Mount Boot at Y: > Update WIM path
        Once copied over, remove Y: mountpoint: DiskPart > sel vol y > remove
        
        
3. Create a 650MB WinRE Partition: WinKey+R > Open: DiskPart > OK
   1. sel vol c
   2. shrink desired=665 minimum=650
      • WinRE partition must have 320MB free (WinRE.wim is ~300MB in size)
      • If this command fails, you will need to use a 3rd party partition manager to shrink the system partition by 665MB [RAW], as the formatted size should be 650MB.
   3. BIOS: cre par pri size=665 id=27
      UEFI: cre par pri size=665 id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
   4. format fs=ntfs quick label=WinRE
   5. assign letter=z
   6. UEFI only: gpt attributes=0x8000000000000001
      
      

4. Copy WinRE.wim:

   MkDir "Z:\Recovery\WindowsRE" ; Xcopy /H "C:\Windows\System32\Recovery\WinRE.wim" "Z:\Recovery\WindowsRE"
   

   • WinRE.wim is normally a hidden file; if it returns File not found, remove /H parameter
5. Disable WinRE: ReAgentC /Disable
6. Set Custom WinRE Path: ReAgentC /SetREimage /Path "Z:\Recovery\WindowsRE"
7. Enable WinRE: ReAgentC /Enable
8. Verify: ReAgentC /Info
9. Remove WinRE Mountpoint: DiskPart > sel vol z > remove > exit
