Update 25.04 to 25.10

1

I sent this message from another computer. I updated my computer from 25.04 to 25.10 and now Ubuntu does not start anymore. All I get is a blinking cursor in the upper left corner.

I tried something:

I started the pc and choose advanced options.

I choose kernel 6.17.0-12 - generic (recovery mode)

I got recovery menu.

I just hit enter on resume (did nothing else) and Ubuntu did start. I tried this several times and every time Ubuntu starts as it should be.

Is there something I could do on the recovey menu to solve the problem???

Hi, @Tukkie!

Perhaps try updating GRUB. :thinking:

Launch the terminal (Ctrl Alt t), enter lsblk -no pkname to get the name of your disk, and enter this line, replacing “xxxx” with the name in question:

sudo os-prober && sudo update-grub && sudo grub-install /dev/xxxx

Unfortunately that solution did not work, the same problem: blinking cursor in the upper left.
