Linux Mint Debian does not start any more

[Leloup]

Bonjour,

For one year, I didn't have any problems until I did an update.
After update, Linux Mint Debian doesn't boot on the VirtualBox 6.1. Screen is black.
I didn't found any more on the Linux site the load debian-8.7.1-amd64-i386-netinst.iso from which I could to restart the guest. I hope.
I tried to launch the recovery mode without any success. Failed to start Load Kernel module.
In rescue mode journalctl -xb is accessible. Screen is still black. I don't have any time to enter my login and password.

I found the lmde-4-cinnamon-64bit load. I can boot on it. But what the next step is? I have to overwrite the entire contents of the hard drive?
Do you have any idea better idea?

Regards,
Leloup

Bonjour

I formatted everything and reinstalled everything.

It's the only solution I found. Of course, I haven't installed everything yet because it's long but next time before updating I'll think twice.

... next time before updating I'll think twice.

Did you set up Timeshift? Just as useful in a VM as a regular install. Even if can't boot the main system, can restore by booting a live session from ISO. Alternatively, take a VBox snapshot before updating. If update runs well, delete the snapshot, thereby merging into the main .vdi file.

Bonjour Linux-rox,

Thank you for these tips. I will try but hopefully I won't have to.
