Ubuntu 17.10 intermittently stalls on booting, Memtest86 ok

Asked by Pablo on 2018-05-16

Ubuntu logo will begin to blink when booting and boot process will stall. I power off with power button and most often on 2nd time around will boot appropriately, although sometimes it will take a third time. At other times it will boot right up normally. This is with Ubuntu 17.10. Can you suggest solution? Thank you (This is similar to earlier question still open....)

Have you ran an fsck on the Linux partitions? You can do this from the Live Ubuntu desktop easily
Make sure you have the latest BIOS too

thank you. I will be back in touch. (I started a new question because I received no further feedback on my earlier question.) I look forward to your walking me through this.

I made a LIve Ubuntu DVD. I booted with it and chose the Try Ubuntu option. I opened the terminal and gave the following command:
sudo fsck /dev/sda1

this is the response I got:
fsck from util-linux 2.30.1

Is that it? I don't know what to do next,. where to I go from there?

(Again, I lament my limited know-how.)

It would be hlepful to me to orient me to checking for whether I have the most recent bios.

Would a solution be to simply update to 18.04?

sudo dmidecode -t 1

Will give you some output then check the manufacturer website. Often the upgraders need a windows based OS.

Did you read the link I gave about fsck? It gives an explanation of the command

Pablo (ceascolombia) said : #7

Thank you for the BIOS info. I will check on possible upgrade.

About fsck, yes I consulted the link y0u sent about fsck, but I didn't understand what to do with it. I think I have used "sudo fsck /dev/sda1" in the past to run fsck from a live Ubuntu DVD, but apparently it is not the right command .... I don't know what to do with the response, "fsck from util-linux 2.30.1". I think I will need for you to walk me through the process.

Thank you in advance

Re BIOS update: My machine is old, and Lenovo doesn't indicate a BIOS update for the version of windows I have (10), only for earlier versions of Windows. I am inquiring how to update BIOS given that fact.

Can you walk me through running fsck with Live Ubuntu CD (see earlier note).

thank you

Pablo (ceascolombia) said : #9

I updated BIOS. Problem persists.

running fsck from UbuntuLive:

ubuntu@ubuntu:~$ sudo fsck /dev/sda1
fsck from util-linux 2.30.1
ubuntu@ubuntu:~$ sudo fsck /dev/sda3
fsck from util-linux 2.30.1
e2fsck 1.43.5 (04-Aug-2017)
fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda3
Could this be a zero-length partition?
ubuntu@ubuntu:~$ sudo fsck /dev/sda5
fsck from util-linux 2.30.1
e2fsck 1.43.5 (04-Aug-2017)
/dev/sda5: clean, 480422/12722176 files, 31583438/50867712 blocks
