Thank you for this answer. I am presently completely blocked: something
went wrong and the computer is blocked by a "defaultuser0"..... This
seems to be a clever invention from microsoft and it is absolutely
unclear how I can recover: I can't restore anything, the system falls
back to this "user" and there is no way to know what is the password
associated!

Were you able to boot Windows after disabling secure boot?  Have you tried
re-enabling secure boot?
 
You should be able to restore the Dell factory configuration per
https://www.dell.com/support/home/ca/en/cadhs1/drivers/osiso/recoverytool/WT64A

 

Sigh!

Moreover, I can't resize the partitions to install linux because the
ntfs partition is crypted (bitlocker).

If you have files you want to save on the NTFS partition you can
try "dislocker" (available thru "dnf install dislocker").

I am stuck!

You can always revert to the factory configuration using
