First, you must open Windows Search, search for “Command Prompt”, and click on “Run as administrator”.

Next, you will run these commands (the texts in bold) one by one:

  1. reagentc /info (This will confirm the “Windows RE location” path. The number after “harddisk” and “partition” is the index and partition of WinRE).
  2. reagentc /disable (This will disable WinRE)
  3. diskpart
  4. list disk
  5. sel disk<OS disk index>
  6. list part
  7. sel part<OS partition index>
  8. shrink desired=250 minimum=250
  9. sel part <WinRE partition index>
  10. delete partition override
  11. list disk (To check partition style—(*) on GPT means GPT, (*) on MBR means MBR)
  12. For GPT: create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac, gpt attributes=0x8000000000000001
  13. For MBR: create partition primary id=27
  14. format quick fs=ntfs label=” Windows RE tools” (To format the partition)
  15. list vol (To confirm that the Windows Recovery partition is successfully created)
  16. exit
  17. reagentc /enable (To re-enable WinRE)
  18. reagentc /info (To confirm WinRE location)

After running the commands (in bold) above, you should try and install the KB5034441 update again.

Please ensure that after running the command in the first step, a Windows RE location similar to this will open: \?\GLOBALROOT\device\harddisk1\partition4\Recovery\WindowsRE. Note that harddisk1 is the index of WinRE while partition4 and the recovery index of the partition of WinRE.

You must replace <OS disk index> with the number after “harddisk” in the first step above (for example, sel disk 1).

Afterwards, replace <OS partition index> with the number after “partition” and “primary” type in the fourth step (for example, sel part 3).

Finally, replace <WinRE partition index> with the number after the “partition” and “recovery” type in step 1 (e.g. sel part 4).
