Can't enable recovery partition after conversion to GPT

Converted to gpt (UEFI), got an error "failed to update reagent.xml, please try to manually disable and enable winre".

Can't enable it, first because it couldn't find files, then I extracted winre.wim out of an installation .iso and put it in C:\Windows\System32\Recovery and still nothin.

Thankfully I was able to boot but the boot took longer than MBR (sometimes it would show the 'loading dots' and sometimes it's just a black screen).

Bios is setup for UEFI mode.

Recovery partition is created and properly id'd and recognised.

Currently reagentc gives me an error b7. Nobody knows what that is.

How do I enable reagentc?

    Hello,

    This issue may be related to the Windows Recovery Environment (WinRE) misconfiguration. Here are a few things you might try:

    Check WinRE Status: Open command prompt as administrator and type reagentc /info. This will show the status of WinRE for the system.

    Disable and Enable WinRE: If it is enabled, you can try disabling it using reagentc /disable, then re-enable it using reagentc /enable.

    Specify WinRE Location: If it’s still not working, you might need to specify the location of the WinRE image. This can be done with the command reagentc /setreimage /path \\?\GLOBALROOT\device\harddisk0\partition1\Recovery\WindowsRE, replacing the path with the actual path where your winre.wim file is located.

    It’s recommended to back up your important files before you try it.

    After hearing and finding the same generic "solutions" on the internet I finally found it myself. (Thanks Microsoft for making a weird ass unreadable error code, 'b7' like wtf does that even mean?)

    No enabling disabling doesn't work, it was already disabled and enabling would throw an error.
    No setting path doesn't work either because it just eats the Winre.wim file and fixes nothing.

    No, I already had a specially made 1Gb recovery partition with all the appropriate markers applied (which is literally written in my post btw).

    Turns out that I had to delete (on my main partition) C:\Windows\System32\Recovery files like "Reagent.xml" and "Reagent_merged.xml", after which the reagenc /enable command would write a new .xml file and work just fine.
