[cros-discuss] Samsung Chromebook 3 in Dev mode wont boot into the Ctrl+l screen (two beeps)

[Andrew]

Hi all!
I am trying to install Windows 10 (via USB flash drive) on my Samsung
Chromebook 3 and I am running into an issue when I hit ctrl+l.

What happens is that when a ctrl+l, two beeps occur and I cant load into
the usb window. I have seen numerous posts on the web about the exact same
problem and all of them come to one of two conclusions:

1. I have to enable usb booting by hitting ctrl+alt+forward arrow, then I
have to type in sudo crossystem dev_bott_usb=1 dev_bot_legacy=1

or

2. My chromebook is an ARM powered Chromebook in which I am not able to
bring up the usb screen.


Now the first suggestion I tried numerous times on my Chromebook and has
never worked (meaning I still consistently get the same two beeps). For
the second conclusion that the web has made, my Chromebook has in Intel
processor inside and has the Intel sticker on the below the keyboard.

I have let my chromebook die (or run completely out of power) before which
I heard could be part of the problem.
Please help me to fix this problem so that I can successfully go to the usb
booting screen.

Thanks,
Andrew

If your Chromebook supports USB booting and Legacy booting you can enable
it using the commands you noted above,
although the syntax shown is a little off, it should be: sudo crossystem
dev_boot_usb=1 dev_boot_legacy=1

You stated that you have the Samsung Chromebook 3, if so, I believe that
uses an Intel CPU, not an ARM chip.
See 'Developer Information for Chrome OS Devices
<http://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices>'
for a list of devices, boards, CPUs, etc.
That page lists your Chromebook as follows:

Manufacturer Model Project code name Board name(s) Base board
Architecture
Samsung Samsung Chromebook 3 Celes celes
strago Celeron N3050

On that page, some Chromebooks have a live link that takes you to a page
that shows more details including if it supports USB booting and Legacy
booting.
Unfortunately, the Samsung Chromebook 3 doesn't have such a link so I can't
tell if it supports booting via *Ctrl+U* and *Ctrl+L*.

2. My chromebook is an ARM powered Chromebook in which I am not able to

bring up the usb screen.

If the information we see is wrong and your Chromebook does have an ARM
chip, then it will not support Legacy booting,
also, M$ does not support ARM chips on anything other than Windows RT.

You can find the version, platform, and firmware your Chromebook is using
by navigating to URL: chrome:help
Then look at the three lines that show that info., for instance, my Dell
Chromebook 13 shows:

Version 53.0.2785.13 dev (64-bit)
Platform 8530.11.0 (Official Build) dev-channel lulu
Firmware Google_Lulu.6301.136.57


If yours shows the 'celes' boardname, then there may be hope, we'll just
have to wait for one of the developers to let us know if your Chromebook
does support USB and Legacy booting.

I'm having the exact same issue. I'm not trying to install Windows, but I
can get it to boot from any other USB drive or SD card either and I've
tested the drives on another device so I know they're bootable.

*can't get it to boot

[RubenD Prieto]

Mine's the XE500C13-K04US with developer mode, dev_boot_usb=1 and
dev_boot_legacy=1 and I still can't boot with ctrl+ l
All I get are two very loud beeps and nothing, and I do have a bootable
braswell GalliumOS flash drive plugged in when I do that
I'm struggling to get this thing working but I really wanna take this
Chrome OS out of the chromebook, more like I want an actual distro running

[Mike Frysinger]

if you have GalliumOS, then boot it using ctrl+u

I tried that, it just beeps once and reloads the white warning screen. I'll
try cloning the iso into the flash drive from Windows see if that's works
cause I used dd last time

if that still doesn't work, you probably want to ask on the GalliumOS
forums instead for assistance. i don't think anyone here is familiar with
it.

CTRL+U should work on all systems today for booting a USB stick with a GPT
formatted disk with bootable CrOS partitions. there's no other dependency
here.

CTRL+L (legacy boot) is much more of a mixed bag. it only works on x86
systems so far (e.g. Intel), and not all systems ship with seabios out of
the box. if you hear beeps when you press that, it most likely means your
flash is missing the code, and you'll need to get a blob from somewhere.
