Black screen again

Dear All,

Hope you are fine.
few months ago I had an issue with the boot of my Eve V black screen with booting error.
Thanks to your help, I did a short modification on the Bios and everything was working well. (boot on hard drive)
However, yesterday, I have got the same issue, so I did the same but still black screen.
There is now blk4 :harddisk and blk5 : block device.
Can you help me please?
Thank
