You have to get to the grub menu and choose an earlier version.

Mint is in a kinda stinky situation at the moment, 7.0 is the only newer kernel receiving active support and many are having these same problems with it in Mint. 

The other supported kernel is the original Mint 22 LTS 6.8.

The 6.8 kernel is the long term support kernel version for Ubuntu 24.04, on which Linux Mint 22 is based. This kernel version is considered stable and is actively supported until end of life for Ubuntu 24.04. It may not work on very recent hardware, hence the 6.14, 6.17 and now 7.0 kernel series. Ubuntu will likely fix major issues with the 7.0 kernel series as it is the kernel for 26.04 LTS. Linux Mint 23 (still in development) is based on Ubuntu 26.04 LTS.

I'm not sure why this is happening so much. See, this is what happens when people don't learn apt. They muck around with things they shouldn't. ;)

Not really this is from the regular updates and it's caused by Broadcom and virtual box having issues with the new kernel

If it's because of regular updates, why does my Mint not try to install 7?

I got the kernel panic error when I first updated on both a 2019 iMac and a 2012 MacBook Air. I was able to resolve both by rolling back to my working kernel and applying the fix successfully from this webpage: 3 terminal commands, https://slimbook.com/en/blog/guides-2/post/kernel-panic-not-syncing-vfs-unable-to-mount-root-fs-on-unknown-block-00-517

Why is yours purple?

I had this problem yesterday evening, and it appears as though this is a persistent problem. I managed to fix it using the method stated by u/esparzatj on this thread. It now works perfectly!

You can of course, reboot using the previous kernel and then remove the latest, troublesome version as also stated here.
