Problem booting current

[Filippo Moretti]

I installed CURRENT with memstick of May the 27th.I tired first UEFI and all I 
got was a flashing - on screenI then tried BIOS+ UEFI and I get a mountroot 
prompt 
due tozfs:zroot/ROOT/default failed with error 22  (wich is the same error I 
got from current a few days ago)reported in a previous message.Are there other 
setting I could try?SincerelyFilippo
