Just as with rescue mode, only the essential services are activated in emergency mode. WebReflection offered his help and script to try it that way. Also, the system does not activate any network interfaces and only a minimum of the essential services are set up. If this work, you should also be capable in the future, whenever the boot from eMMC would be available, to copy /boot to a local eMMC folder, umount it, re-copy back to the eMMC the boot content,  re-generate the fstab, and live hackily ever after. So I decided to make an article on how to fix these issues in Ubuntu, in case you run into the same issue. I said, this was mostly so I have a handy reference in case it happens to me Obviously, it was related to upgrading packages on Arch (which I currently do Some of its uses are examining the system state and managing the system and services. I'm glad we've got it working on a USB device already. I am  pretty sure that will solve your problems, because you have a running Syslinux initialization from your stick, and that is already in the right disk and it's working. Hit ESC key right after the BIOS logo disappears to display Grub menu. So my guess: there is some GPT residue left on the eMMC, which causes the wrong UUID's.Possible solution: remove the residue and reinstall. So please ignore this message, I'll head to the other post. The steps to resolve wasn’t hard, but I wasn’t able to find a single thing on Is this an option  or you really want to boot from eMMC 'cause somebody managed to do so? At this point I wonder if it could make sense to have your system on an SD card and mount the eMMC as extra storage space once booted from such card. Of course you didn't read them all, I just wanted to provide some more reliable sources. My question: does this seem like a reasonable guess and solution? could have been and how to resolve it. Pug dad. To make any changes in the system we must first mount filesystem in read-write mode. Not sure how much I am helping, apologies if I'm rising confusion instead. That being said, I'm not that expert neither, but I've spent quite some time figuring out how to work around gotchas here and there ... the Gizmo 2 board for instance wouldn't boot without specifying UEFI=NO EDD=NO SWAP=0 at installation time ( first bios that needed EDD to be forced to 0 ). It's not that during booting the /boot partition itself is not recognized but the eMMC is that which isn't recognized by seaBios. The OP there is using another script and a GPT partition table. [SOLVED] Booting into emergency mode after fresh install, incorrect... https://johnlewis.ie/custom-chromebook- … -download/, https://bbs.archlinux.org/viewtopic.php?id=200048. in RHEL6.1 there was a bug that broke that functionality, but in rhel 6.2 and above, it's back up and functioning. Okay, easy enough, let me ax that module and go from there. Pretty sure it was Firefox Developer Edition that did it, but that’s for. So I had to reinstall and change back to MBR. Neha Muthiyan. Now after rebooting into emergency mode, blkid and lsblk -f give the same UUID's, but differ from /etc/fstab. Husband. This worked. This black screen showed up several times, completely at random the last 10 or so times I was in the recovery shell. But, as you can read here (link) there are some issues. During this second installation process I switched to another USB flash device on which I had to install /boot, because I couldn't install GRUB as it was recognizing multiple partition labels. check what was in journalctl as it was supposed to give me some insight. ...When I check the eMMC, then I notice that there wasn't anything new written to it. Pretty sure it was Firefox Developer Edition that did it, but that’s for another Yesterday I changed the partition table of the eMMC and the USB flash device to GPT and back to MBR. Without UEFI it will fully erase your disk creating optionally the SWAP partition and the rest will be an ext4 with the system. EDIT: I changed the syslinux.cfg file back to /boot instead of / and now the system booted! In order to boot Arch Linux, a Linux-capable boot loader must be set up. EDIT: the other post didn't give a working solution, so I'd like to continue this thread  -> see message #5, Last edited by tvdbarch (2015-07-27 13:38:48). I've used my installer on eMMC partitions too, but it looks like you are stuck with some guide that tells you you should do things in a certain way ... mind sharing that link? After which it continues to a black screen where it is stuck. We can boot into rescue mode in two ways. You will get several screens to scroll through. This worked for the 'a start job is running' error, it also booted into non-emergency mode, but a lot of errors remained during booting. recovery console.

Now it gives in the recovery shell the error that /sbin/init doesn't exist and that I'm on my own now. SD cards also work, but seaBIOS is also picky on them. able to get to troubleshooting. And I'm completely fine with the workaround. Emergency mode is suitable for debugging purposes. But then, with your USB-boot stick in, and verifying that your eMMC is available, you can mount the USB to the /boot folder, you can have a look there and try to understand if it looks OK ... type, Last edited by WebReflection (2015-07-28 12:34:05), watch out I copied and pasted `rw quiet splash loglevel=0 console=tty2` it shoukld have been `quiet splash loglevel=0 console=tty2` sory for the mess, FWIW I've actually added BOOT_LOUDLY flag in the list of configurable options and that will take care of NOT adding `quiet splash loglevel=0 console=tty2` to the config, Last edited by WebReflection (2015-07-28 12:45:18). In emergency mode, only the root file system is mounted, and in read-only mode. 2. In latter case I am afraid without an asus c300m there's not much I can do, except pushing (which I've done already) a  slightly modified version of my installer.This is latest change: Basically I've modified it in a way that Syslinux will use the SD card to boot the OS, but will try to use the eMMC as disk. If none of this works, I'm afraid I've exhausted all my knowledge. After that, I decided to finally decided to follow the on screen directions and If not, try another package. I haven't read all of them  but in this link it's stated that eMMC won't boot. (recently clean installed) decided to lock up on me. The procedure is quite different for BIOS and UEFI systems, the detailed description is … In emergency mode, the system mounts only the root file system, and it is mounted as read-only. Some potentially important details-I followed the beginner's guide-Because the payload doesn't recognize the eMMC of this device (a known bug for baytrail devices https://johnlewis.ie/baytrail-release/) , I have to put the /boot directory on a separate device (an external USB device in my case). You should just follow the exact same procedure you've followed before, this time archibold.sh will create the right config. Or I messed something up and it is dependent on my other usb device where the live arch iso is. If this happens in a VirtualBox VM then it may be that it has failed to mount one of the partitions in /etc/fstab - unfortunately it fails with "welcome to emergency mode!" Apparently this problem was reported just a few days ago. When you dropped into the emergency shell please run two commands and give me the photo about the output. Oh shit, did my drive crash? EDIT: after another reinstall I have to conclude that I miss typed something before when calling your script, now everything was as planned after installation, except for booting Gets into emergency mode again and continues to the black screen. i just reboot the system sevaral time but still the issue is not resolved . Could you please provide a link to the relevant thread for the case of somebody else having the same issue but finding only your thread? Your original ubuntu OS should be out of the emergency mode now and should boot just fine. So I went back into the live-arch. Google gave different solutions, but it mostly came down to some residue of previously used partition tables. So I might have done something wrong with selecting the right device, or your script goes wrong somewhere. It got into the bootloader menu, but after choosing the only option available, the only thing that came up was a fancy archibold sreen. *Yesterday I changed the UUID values manually in the fstab file, following the values from blkid. If this works, we can discuss later on how to put a swap in the eMMC. Booting any Linux distribution into single user mode (or rescue mode) is one of the important troubleshooting methods that every Linux geek should know. If you keep having hard time, you could give archibold a try. Normally, the fsck program will try to handle file systems on different physical disk drives in parallel to reduce the total amount of time needed to check all of the file systems (see fsck(8)).. Two keyboards and neither of them were responsive enough for me to be able to Stage 1 : Part 1 - Load MBR - At boot, the BIOS loads the 440 byte MBR boot code at the start of the disk (/usr/lib/syslinux/bios/mbr.bin or /usr/lib/syslinux/bios/gptmbr.bin). post.

As far as I know, nobody managed yet to boot a non-ChromeOS distro from the eMMC on a baytrail device. Thank you very much!! Like But even then, we would still have the eMMC boot problem. Now armed with a bootable Linux system in the palm of my hand (thumb? Father. my installer went up and running quite smoothly without UUIDs problems but in other devices I had to regenerate the /etc/fstab to make it work (through the procedure you already know).

See systemctl(1) for more details. I changed that.Rebooting gave again the "loading /vmlinuz-linux failed" error. emergency launches a shell even earlier, before most filesystems are mounted init=/bin/sh (as a last resort) changes the init program to a root shell. This brings me to my next best guess. First, we will see how to boot into rescue mode and emergency mode in Ubuntu 20.04 LTS distributions.
