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.

Grub and the Microsoft Ransomware (lemmy.ml)

TL;DR: bitlocker does not like grub

Full story:

Months ago I installed fedora on my desktop, dual booting Windows 11.

In all this time I never had the need to boot into windows. I remembered that it worked fine after install, good, and then I forgot about that.

Today I needed a specific windows only software, so at grub I chose the microsoft bootloader and... BITLOCKER.

Huh? Bitlocker? Me? What? Searched frantically for that decryption password in my keepass, did not find. What?? How???

After a few minutes staring at that screen I thought, ok let's just wipe that shit and reclaim the space. I went back to linux, opened the partition manager, then remembered that i had something important in single copy over there. Noooooo

Went back to the boot screen to try again, still failed password.

Then I notice the error:

e_fve_pcr_mismatch

that mismatch lets me think that maybe I had something wrong in my booting.

I try to put windows first in the bios and it works! WHAT THE...?!??

So, if i put linux first, then launch windows from grub, bitlocker takes the windows partition under ransom, i can only access if windows is first. And of course in windows 11 x64 is no longer possible add linux partitions in their boot manager (previously it was possible)

Incompetence or maliciousness?

MX Linux. Prior to install I disabled bitlocker in windows to be able to resize the part with gparted. Once in windows again I re-enabled it.

The MX installer is very complete, I was able to directly use LUKS to encrypt my linux partition, and I chose btrfs with multiple volumes. Once grub was installed I needed to change my BIOS to boot from linux partition, this is when my first boot in windows asked for the key.

thanks! You've satisfied my curiosity, and piqued my interest in MX Linux.
