Recovery mode error hp15

i am new in the forum 🙂

I cant start ubuntu in my notebook hp15.. i had ubuntu for a while alongside windows 10 in this computer. I used both OS normally until last week, when suddenly after choosing ubuntu in grub it went to recovery mode, showing some errors like:

” modsign: Couldn’t get UEFI db list”,

“do_IRQ: 1.55 No irq habdler for vector”,

“do_IRQ: 2.55 No irq habdler for vector”,

“”do_IRQ: 3.55 No irq habdler for vector”,

“couldnt get size: 0x800000000000000e”

and so on. I tried cfdisk and other commands, but it didnt work (or i did’nt write the commands properly, perhaps?) It didn´t bother me much because i was already thinking about making a new-clear install of both windows 10 and ubuntu this weekend(windows has been a bit laggy lately), however.. I used a liveCD again today trying to recover my data before wiping my hdd and making a clean install, but i forgot some of my files were “protected”/”encrypted” so i wasn´t able to get all my docs, classes,etc.

But somehow now i cant even boot ubuntu, even in recovery mode. I used a livecd again today in order to install repair-grub from the ppas, but after making the socalled grub repair and rebooting my computer, the problem stayed the same.

here are some pictures and the test from the boot repair

Thanks in advance!
