From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So I got this weird bug – I updated my Pop_OS install and now Linux doesn't boot anymore. I should probably boot from USB and fix this. I could figure it out on my own, but maybe it will be good knowledge for people searching on engines so any advice is welcome. Windows still boots properly. Let's give people some alternatives to reddit :)

If Windows and Linux are installed on the same drive under different partitions, I seem to recall that a Windows update can fuck your Linux partition.

Was there a Windows update recently?

No, it can just affect the boot record in some cases. This is not that case.

This would be what I was thinking of then, thanks for clarifying.

I have been avoiding a deb upgrade to 12 1 because of this. However you have me wondering if I'm overly paranoid as my installs while on the same bootloader are on different drives

I think it's only Windows that will break things, so you should be good. Also, I think it's only when it's on the same drive, but I'm not sure. That's how mine was that got messed up. I just ended up ditching Windows because I didn't need it anymore though. That's the proper solution.

The plan is to ditch win in the long term. Not quite at that point yet.

I'm not overly fussed about upgrading windows any further for this reason but I do remember seeing deb have a similar solution for the bootloader bug it's addressing with the warning in the release notes it spooked me

Disconnect the other drive when you do it and you'll be fine.

It wasn't the windows update. It happened after a Linux update.
