Completed installation of Ubuntu on Lenovo 100S. Will not boot

in flag

The Ubuntu installation completed without any errors. At the end it said to remove the installation USB and restart, which I did, but it won't restart.

I'm installing on a Lenovo 100S-14IBR

Steps that I used:

  • Downloaded Ubuntu 22.04.2 LTS
  • Used Rufus to create a bootable USB
  • In UEFI settings, I set the boot order and disabled Secure Boot
  • It booted from the USB
  • I selected to install (not "try out")
  • I chose the destination drive. I chose the 64GB eMMC drive, not the 256GB SSD.
  • I chose to delete all existing partitions (not keep existing windows install)
  • For the next 1/2 hour, it installed all the software
  • It asked me to remove the installation USB and restart the computer, which I did.

Ubuntu will not start up. I thought maybe I installed on the wrong drive and that I should have used the 256GB SSD.

I tried re-installing using this drive. But I immediately got errors: "error during write on /dev/sda" and "Failed to create a file system, the EFI file system creation in partition #1 of scsi1 (0,0,0) (sda)"

I then left the computer for a while and when I came back, Ubuntu was up and running! I have no idea how. I worked for a while with Ubuntu and installed VsCode. All seemed well. Therefore, I deleted this question.

But later that day, I powered the computer off. Now it will not boot into Ubuntu, no matter what I try. I tried changing the boot order. This is my current boot priority order:

Windows Boot Manager
eMMC Card0: SanDisk iNAND 64GB
SD Card1
SD Card2

When I take the boot USB out and press the power button, The screen briefly gets bright, then displays "Reset System" in tiny print in upper left of screen and then screen goes black. It keeps going through this cycle.

If I leave the boot USB in the drive, it only boots into the Grub menu.

======= PROGRESS =========

I was able to get Ubuntu to boot again. But not normally by just pressing the Power On button. Now I need to first press the "NOVO button" to get this menu:

Normal Startup
BIOS Setup
Boot Menu
System Recovery

Up until now I was always selecting "BIOS Setup" and changing the boot order there. This time, I selected "Boot Menu" which shows this:

  1. Ubuntu
  2. WIndows Boot Manager
  3. eMMC Card0 Sandisk iNAND 64GB
  4. ATA HDD: Intel SSDSCKKF256H6 SATA 256GB

Setting the eMMC card in the BIOS setup was not working, so now I selected number 4, the 256GB drive. Now Ubuntu booted up!

I'm glad that I didn't brick the PC. But I still don't know how to boot up Ubuntu without going through this process each time. The 256GB drive doesn't appear (as such) in the BIOS boot priority menu. Maybe one of the other entries refers to it.

But also, it appears that I may have messed up the setup of these disks, since Ubuntu itself should still be on the 64GB drive. Why do I need to boot from the 256GB drive in order to get to it. And how would I fix this?

======= SOLUTION ??? ======

I moved the first "ATA HDD" entry in the BIOS boot priority list up to the top. Now when I just hit the power on key to power up, it boots into Ubuntu. The solves my main issue of being able to easily boot Ubuntu. But I should still try and find out why I need to boot off the 256GB drive when Ubuntu is on the 64GB drive and fix this. I could have problems later because of this.

I ran gparted from the internal Ubuntu. Here are the results:

Partition Name File sys Label Size Used Unused Flags
/dev/mmcblk1p1 EFI System Partition  fat32  /boot/efi  512.00MiB  7.09MiB  504.91MiB  boot,esp
/dev/mmcblk1p2  ext4 /,/var/snap... 57.74GiB  17.30GiB  40.44GiB
unallocated unallocated
Partition Name File sys Label Size Used Unused Flags
/dev/sda1 Basic data partition ntfs  DATA 238.47Gib  175.03GiB  63.44GiB msftdata

I am still confused. It's showing that the 64GB drive contains a boot partition and an ext4 partition that should contain Ubuntu. The 256GB drive has an ntfs partition for data. So why do I need to boot from "ATA HDD: Intel SSDSCKKF256H6 SATA 256GB" which would be the data drive.

I'd like to reformat the 256GB drive as ext4, but I don't know if doing that will again prevent Ubuntu from booting.

Can you set the default boot device in UEFI settings? Maybe the 64GB eMMC is not set as the default boot device?

@ArchismanPanigrahi PLease see updated question (under "PROGRESS"). I was able to boot Ubuntu, but not by setting the eMMC as the boot device. Your comment is what got me thinking that the problem is most likely that it is trying to boot off the wrong device.

Try reinstalling grub (the bootloader) in the 64 GB drive

Also try the other answer with the 64 gb drive, if the first answer in the link does not work

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
