Linux Lite Forums

Hello

I'm trying to install linux lite on a 2012 Acer Aspire S7,

I followed the install tutorial : downloading ios, writting the iso on a usb stick, booting with usb stick, booting on live system then installing linux lite following the instruction

Linus will be the only operation system, so i installed using ''erase disk and install linux'' option.
After finishing the install, the only option is to restart the pc but it boots directly on my usb key.

When i restart it without they key, i have a black screen with the mention "BootDevice Not Found"

UEFI is enabled
secure boot is disabled

i tryed reinstalling linux lite with different options, i tryed to use another usb key, with/without internet etc

I can't really know if the issue is from the bios or the key or a bad installation ...

If anyone know a fix !
Thanks a lot for your help !

Hi,

-You forget to mention if you checked the data integrity of that file (Linux Lite 6.6) before you created your Live USB
To check that it's not mention in the Tutorial of Linux Lite...
I think you can do this by putting your Linux live installation in your PC. But if I read well, you "said" you tried different ways, perhaps you have another computer where you live...

If you have another computer to try different options to install Linux Lite. If that's windows Balena Etcher is a reliable way to create that Live USB, NEVER try it with Rufus. Rufus is known to cause problems.
But to check the data integrity of what you downloaded is different than with Linux

with Windows
Press Windows+R to open the Run box
Type powershell and click OK
The Windows PowerShell window will open
Run the following command:
Get-FileHash C:\file\path\my_file.exe -Algorithm SHA256
+++Replace C:\file\path\my_file.exe  with the path where is your Linux ISO ,perhaps on D:\ ...

To check that on Linux
I know when someone made a "\" partition and a "home" different partition by default the terminal will open with the name you put that profile of Linux, with the UEFI automatic installation I think it's the same. So if you put a name : Computer_of_me that's where it'll open the terminal..

So your ISO (Linux OS) in linux environment must be in the Download folder. Just cut it and put it the main folder (the Computer_of_me) if you moved that ISO you just have to type in the terminal:
sha256sum linux-lite-6.6-64bit.iso
(then Enter)
Copy that result of letters, number, etc in a text editor and compare each one with this:
732b5561783c7203e3b919a4c55508a4256c13785b80e2e47019d817b89e9543
the official sha256 signature of data integrity in the main website of Linux Lite 6.6

-But it's possible all of your USB could be damaged at first but all of them it's not probably true
First try to check the data integrity of your ISO before copy them in your USB(if that was your problem at first) and then this community will try to help you with other issues.

Thanks for your answer Edimion
(i'm a beginner on Linux and my english is not perfect...)

So ! I checked the data integrity of my Linux ISO and it's all right, the same result of letters and numbers.

I had tried only with Rufus, i tried with Balena Etcher this time and no problem to create my bootable USB key.

I started my laptop where i want to install Linux with the key. However just before the screen where you can choose to boot live linux or direct install LL, i have an error message "file \boot not found". I tried to install LL 6.6 after a check for file corruption but after a reboot, same problem as before, "bootdevice not found". Not really a surprise...

This message means at least two things:
1. The destination drive is damaged. This means it has bad sectors.
2. The drive has an MSDOS type partition. This always leads to errors since your machine has UEFI firmware.
In either case, you need to diagnose the disk.
For that, you need a tool that does that.
The tool is called GPartEd Live, meaning that you have to go to the site, download the ISO image, burn it on an USB stick, then boot it.

https://gparted.org/livecd.php

Download:

https://gparted.org/download.php


After the booting process finishes, you will be in front of the GPartEd window.
It will tell you about the drive's partitions, types, sizes and the rest.
It will also tell you the type of partition.
Select from the Menu View > Device information.
It can be either "MSDOS" or "GPT" (UEFI, Global Partitioning Table.)
If the drive is MSDOS partitioned, than you have to delete all, until all space says "Unpartitioned" or "Unallocated".
Now choose from the menu Device > Create partition. Choose the GPT type, then "Apply".
If you know how to go from here, than do it. Create and format the partitions, starting with the FAT32 boot partition and then the others.
If you are unfamiliar, then stop the computer, insert the boot drive (Linux Lite) and reinstall, with the default option.
Let the installer do the rest. Just follow the on-screen instructions.

Keep us updated.

Best regards, Șerban.

Yes, also my English is not really goob tsu02.

That's probably the main issue of tsu02, probably some sector of his disk are damaged.

I recommend you tsu02 try to use Windows 10 to fix that because of his graphical intefax. If you have one cd try to find that option: Here is a link https://www.avast.com/c-chkdsk-windows

After that  :computer

Don't forget when you press the button F2 or another to watch the BIOS Setup of your computer, don't forget to choose your USB memory to boot first. The one that said the brand of you memory stick ,not UEFI plus the name of that memory stick...

Thanks Serban & Edimion

As you told me, I used GPartEd Live
I have 3 partitions (4 with the usb key)
dev/md126 : unallocated and unrecognized partition table
dev/sda (usb key)
dev/sdb : none partition table
dev/sdc : none partition table

I created a new partition for the first one (gpt)
I didn't do anything with the other ones

As i didn't know exactly how to format the partitions thanks to GpartEd, i stopped the computer, reboot to install linux lite.
Installation ok, so i restarted the computer, modified the boot setup to put the HDD first, took out the usk key, and...
Same message unfortunately "Bootdevice not found" ...

I checked again with GpartEd live, and the first partition is unrecognized again

Other information, i stopped to use Balena Etcher because there were some errors to create my bootable key, so instead i used unetbootin ; same for the linux lite bootable key (i have 2 different usb keys)

It looks like the storage dev/md126 is the problem.
As it appears, you have 4 different storage media (dev/md126, dev/sda, dev/sdb dev/sdc).
I only encountered this once long time ago, when SSHD was somehow common on the market.
The listing is abnormal, since the internal storage is unrecognizable, coupling that with the previous messages, my conclusion is that you have a soldered (onboard) SSHD and the buffer partition (the SSD, dev/md126) is gone. That means the internal drive is gone. If there is another way to check this, please, do so.
In another environnement if the internal drive was functional, it would be listed as dev/sda/, but you said the dev/sda/ is an USB drive (stick).
This only happens if the main drive is damaged.
Assuming I am wrong, then it is possible that the unallocated space is usable, but without knowing the available space on each partition, it's impossible to make any educated guess.
I need to see the whole GPartEd screen to understand what is happening there.
Take a picture of the entire GPartEd screen and post it here.
You can also try to create a new partition on /dev/sdb/.
Bunt since I have no clue on the size of the media it's impossible for me to figure out what to do with so less information.


Sample screens:

1. The GPartEd main screen, showing main drive's partitions:


As you can see, the partitions, are listed like /dev/sda1, /dev/sda2, etc. and with the respective sizes.

2. The GPartEd main screen, showing the list of drives:


3. The GPartEd main screen, showing the drive's /dev/sdb partition:


I hope now you understand what I need to figure out what is happening out there.

Meanwhile, search on YouTube any video regarding "Using GPartEd beginner tutorial" and study the partitioning process.
Take a look at this one:


In your message you mixed all the information you remembered, regardless the meaning.
So, I can only guess that the main drive is /dev/md126
Post the screen images and we'll se what can be done.

If there are two disks in the S7 running RAID, it may be confusing things.
Check in the BIOS settings under 'Information' to see how many physical disks there are and in the BIOS under 'Main' to see if RAID is enabled.

Hi guys

About the disks number, here are the informations in the BIOS :

HDD0 Model Name : LITEONIT CMT-128L3M
HDD0 Serial Number : 002242101572A
HDD1 Model Name : LITEONIT CMT-128L3M
HDD1 Serial Number : 002242101572B

And under Main :

SATA Mode      [RAID Mode]
