Issues with booting an OS

Hey All.

I just downloaded mrchromebox’s software on a new jasper chromebook. Was not able to remove WP due to the Jasper models being limited but now that I am able to boot my own OS alongside Chrome OS, I am having some difficulties.

For starters, I am trying to boot an Arc Linux IOS through a flash into the chromebook but it simply gives a multitude of errors. For starters I get the "/syslinux/vmlinuz.B not found " error and then also the “hd0,3 not found” when specifically tryna boot from my flashed usb.

I did some digging online and spent time messing with grub before attempting boot through the USB again but still to no avail, figured I would ask yall how I can actually get to booting arc and using any OS other than chrome on this guy.

Thanks!

What board are you work with?
How to find out:

Hey s31bz, sorry for the late response.

My board is under the name “BLIPPER”

Sorry for the delay in my response as well. Let me know if any of this is helpful or if you’ve tried it already.

Looking up your model, it looks like it uses CR50 for write protect.
According to MrChromeBox’s docs, if you undo the bottom panel and disconnect the battery you should be able to remove write protect.
Using my C13 Yoga Chromebook as an example:

  1. Unscrew bottom metal panel
  2. Gently pull battery cable from the connector to disconnect it
  3. clip bottom metal panel back on
  4. Plug into power, boot into ChromeOS
  5. Follow the instructions here to flash full UEFI firmware, thereby disabling firmware write protect
  6. Install whatever Linux distro, following the guide to get sound and keyboard working after

If you flash Full UEFI firmware, reboot, and then boot to whichever Live USB of ArcoLinux/Arch Linux/Fedora etc, are you able to properly boot?

Have you tried separate flash drives?

Note: Esc is the key you’ll need to press to get to the boot menu once you see the Coreboot bunny logo.
