Ok, so I have now installed CloudReady, switched to the beta channel as well, but I can’t use Linux because my CPU is not secured against Spectre/Meltdown and CloudReady doesn’t come with microcode updates. Until that comes, my ThinkPad will probably only be for browsing, watching videos, and blogging…

Update: Fixed it.

Bill Dietrich > I can’t use Linux because my CPU is not secured against Spectre/Meltdown and CloudReady doesn’t come with microcode updates Please explain more. How does booting one OS prevent you from later booting a different OS ? Or does "can't use Linux" mean "can't run Linux in a VM under CloudReady" or something ? Thanks.
Jan-Lukas Else How I got Crostini to work in Chrome OS Flex I blogged that I could not run Linux support (Crostini) on CloudReady and Chrome OS Flex. Every time I tried to enable Linux support in the settings, the activation failed with an error. Also when I then tried to open a Linux terminal the following error came up: According to CloudReady, this is due to “unmitigated CPU vulnerabilities”. Now, hidden in a Reddit comment thread, I found a solution that actually works. For this I had to copy Ubuntu to a USB stick and start it on the laptop in liv…

- Colin Walker Booted into Ubuntu on USB, mounted the partition but it won't let me re-save grub cfg because it is read only and I can't change permissions or ownership 😥
- Colin Walker This could be useful. Jan-Lukas has got Linux support wor… This could be useful. Jan-Lukas has got Linux support working in Chrome OS Flex on an unsupported device.
- didi Suddenly, ChromeOSFlex can replace my Win10. Without the Linux Extension its sinnless for me
- Anonymous Hi, many thanks for the small tutorial! I'm trying to play with Java on a Dell latitude but I can't... Can you be more specific where the line should added please? "After Linux in all entry" seems not fully clear to me as I'm not a Linux addict (yet^^) Thanks in advance!
- Anonymous Hi, I got this to work with a 4th generation HP 700 G1 i5-4570 but unfortunately didn't work for me for the 3rd generation HP Elite 8300 i5-3470 <- don't know if I can make this useful again in terms of a crostini linux beta install
- Anonymous Sorry for being a newbie but where should we paste the “ kvm-intel.vmentry_l1d_flush=always” after the curly brackets or inside the curly brackets just after each linux or somewhere else?
- Denis Hi. I installed the last version of CloudReady on my laptop, and as expected Crostini doesn't work. I'm not a Linux user, and don't understand anything in that, i just need to download VS Code, and as i understood it is possible only with Crostini. Maybe anyone can do a short video tutorial of what's done here on this page? Because i absolutely don't understand what's going on here and possibly I'm not the only one who doesn't. Video tutorial would be very useful. Thank you in advance!
- Anonymous No need for Ubuntu, you can just use crosh and edit the file with vi. Thanks for the tip, worked well on Mac mini 2012.
- Anonymous Latest Chrome OS Flex dev version already has this fix, but still can't install Linux on MacBook 6,1
- Anonymous How to install ChromeOs flex on SSD.. I have one hdd and one SSD on my device.. whenever i try to install chromeos flex or cloudready.. it always get installed on hdd plzzzzzzzzzzzzz helppppppppp
- Jarrod sudo sed -i -E '/^\s+linux/ s/$/ kvm-intel.vmentry_l1d_flush=always/' grub.cfg Above sed command will append 'kvm-intel.vmentry_l1d_flush=always' to lines in 'grub.cfg' starting with word 'linux' (prefixed with whitespace) to file 'grub.cfg'
- Jarrod I linked a tutorial where, although they are solving a different problem, the author outlines a method for altering FlexOS grub well. For reference, instead of (appending 'kvm-intel.vmentry_l1d_flush=always') fixing crostini, the tutorial author (appends 'cros_debug') enables dev mode. Enabling dev mode is NOT necessary to fix crostini, but the tutorials method may still be informative, and the audience may overlap. As a side note, I have also had luck fixing ChromeOS Flex no audio issues on …
Daniel Unfortunately with the newest Version and with my MacBook Pro 7.1 (the white MacBook) it did not work. :-(
