Why won't windows XP + 10 boot?

Question

Windows

I did the installation of windows xp + 10 according to the guide , this
guide everything worked out fine, then I started setting up and installing the software, everything worked perfectly

. etc., only in this particular case I don’t understand what to do, I didn’t have to put 2 wasps together before, who can tell me how to restore the bootloader and not overwrite both?
ps probably stopped loading XP after I changed the drive letter where XP lies in the standard win disk management, tried to return it but I didn’t remember the letter correctly, which was the roofing felts, these are unrelated things ..
UPD.
EasyBCD says that the bootloader goes to the ntldr file on the same partition where the boot files (500mb) are located,

how to open this ntldr and see what's there?

More connected! In XP, the drive letter is registered in the registry for a lot of things, and in terms of places, the paths are not relative (to simplify). And now it can't find the specified file.

There are so-called services for registrars - Backorder .
"Backorder" allows you to apply for registration of domains whose registration period is expiring.
The system will automatically track and register the domain when released.
You no longer need to remember, wait or keep track of the desired domains (often domains are released at inconvenient times, such as late at night or on holidays, when it is not always possible to be near the computer).
It makes no sense to write where exactly this can be done, since a number of registrars provide similar services, of course, the cost of such services is more than the cost of this domain zone.
