Trying to install Ubuntu on external hard drive and Grub on internal harddrive – BIOS

im trying to install ubuntu on my external hard drive and Grub on my internal hard drive, i once installed ubuntu on my internal but i dont have much space on my main SSD, i use a laptop and i decided to replace my old 500gb HDD with a 250gb SSD and i use my old one as an external disk.I already made a question asking how to install this but it was pretty bad an i didnt gave much info. After i tried to install it and rebooted my computer i got this error:

error: no such device: e5ba289-b231-4ad9-abda-b6a8a04c1c1e error: unknown file system entering rescue mode…

After i saw this i rebooted my laptop and booted my USB with ubuntu, and installed boot-repair, after another reboot i got the normal windows 10 starting screen.

I have the log from boot-repair if you need more information please leave a comment and i will give you the required information.

Hyperthreading enabled in BIOS, but not working under Ubuntu 18.04

I am running a standard Ubuntu 18.04

$  lsb_release -a LSB Version:    core-9.20170808ubuntu1-noarch:security-9.20170808ubuntu1-noarch Distributor ID: Ubuntu Description:    Ubuntu 18.04.2 LTS Release:    18.04 Codename:   bionic 

But I am lacking hyperthreading…. It’s 100% enabled in the BIOS. I disabled and enabled it just to check whether the problem was there, but it’s not… However cpuinfo says: core : 4, siblings : 4, while it should be siblings : 8…

https://ark.intel.com/content/www/us/en/ark/products/88196/intel-core-i7-6700-processor-8m-cache-up-to-4-00-ghz.html

I don’t remember when this happened in my desktop… maybe since the upgrade from 16.04 to 18.04…
Any suggestion is welcome, I am pasting the cpuinfo.

Thanks,

Alex

BIOS menu to enable SSD as boot device

I’m using a Dell Inspiron 15 3542, and trying to install Windows 7 on an SSD I’ve put in place of the DVD drive. I could reach up to getting the SSD recognised in Disk Management of my existing Windows installation and also created a dedicated Disk and partition of that entire SSD drive.

Now when I try to install new Windows 7 on this SSD, I get the following error after selecting that drive as the target location:

“Windows cannot be installed to this disk. This computer hardware may not support booting to this disk. Ensure that the disk’s controller is enabled in the computer’s BIOS menu.”

Looking at this message, I first updated my BIOS to the latest version A14. Then some help on Google search brought out that I need to change the SATA option to ‘AHCI’ from the boot menu. To my surprise, AHCI is already selected and there is no other option to select.

Although the SSD is displayed as an ‘ODD’ in BIOS along with my regular hard disk as ‘HDD’, I cannot see any option to change the boot device from HDD to SSD, it only shows HDD, CD/DVD, USB Storage and network.

I’d be shortly uploading images of all my BIOS settings.

Two MSI Z270 SLI PLUS have different graphic output quality (BIOS mod?)

I have two MSI Z270 SLI PLUS motherboards with intent to install matching hardware /software configuration. Unfortunately, they are not identical: one has BIOS E7A59IMS.140 from 12/15/2016, the other – E7A59IZ1.1J1 from 07/06/2017:

v.140 v.1J1

First puzzle: current highest official BIOS version is 7A59v1A from 2018-07-17.
M-Flash recognizes E7A59IMS.1A0 file on the first mobo (14), but not on the second. I attribute that to 1A being less than 1J, but would like to have a confirmation.
Even so, i can’t explain dates being out of order.

Googling E7A59IZ1.1J1 results in only two links, https://bios.ethosdistro.com/motherboard-bios/current-bios-list.txt and a related direct file URL. So, this may not be an official BIOS?
Is there a way to re-flash 1J to official one (1A)?

Both sets (mobo + cpu + ram) have passed rigorous (24+ hrs) MemTest86 v7.3.


Next, Windows setup (from the same USB drive) looks normal on 14: v.140

but has dithered color depth on 1J: v.1J1 and lower resolution (dialog fills entire screen): v.1J1 occasionally with color (and in Classic theme!): v.1J1

Since CPU graphics is used on both, is this a result of BIOS mod on 1J, or 2nd CPU is somehow damaged? (I thought about swapping CPUs, but haven’t gotten to it yet, will try next)

Reverted BIOS to default, now don’t have GRUB?

I have a lenovo laptop with Windows 10. Some time later I installed Ubuntu on this laptop and could choose whether I wanted to use Windows or Ubuntu from GRUB. Today something strange happened, I turned on my PC as usual, but instead of GRUB menu I saw Lenovo Boot Manager with options Windows, Ubuntu and HDD, all of them sent me back to this Boot Manager.

I went to BIOS and set all settings to default. After that Lenovo finally loaded, but I don’t have GRUB, Window is just loaded like Ubuntu was’t installed at all.

How can I restore GRUB or at least delete it together with Ubuntu to reinstall them later?

Is there an alternative to mkusb to install Ubuntu on a portable SSD that works with both UEFI and BIOS boot methods?

I’ve successfully used mkusb to install a persistent Ubuntu 18.04.2 LTS system on a new Samsung T5 USB SSD. What is nice about mksusb is that it creates a bootable system that works on a wide variety of computer systems. However, I would like to have a portable ‘real’ Ubuntu installation vs. a live/persistent install that works with both UEFI and BIOS boot methods.

The process outlined here looked like it would do the trick, but in my case I’m just presented with the grub prompt when booting the drive. Note, that I interpreted the step:

Cut grub.cfg from sdx5/boot/grub and paste to sdx3/boot/grub, overwriting the existing grub.cfg file 

…to mean that I should move the new grub.cfg file from /dev/sdx5/boot/grub to /dev/sdx3/boot/grub, overwriting the grub.cfg file created by mkusb and deleting the grub configuration file created by the installation from the installation partition. Also, /dev/sdx3 was not mounted after the Ubuntu installation completed, I had to manually mount it (/dev/sdx5 was already mounted on /target).

Since mkusb without modifications works fine with the T5 SSD drive, I assume that there is something about the Ubuntu 18.04.2 LTS installation grub.cfg file that is causing an issue.

Is there an alternative approach that would work, or is there something inherently different with a portable SSD vs. a USB thumb drive that prevents creating a truly portable drive?

Ubuntu not booting after BIOS update boot-repair disk fail

complete Linux noob here.

I’ve been struggling with getting my Ubuntu boot up and running after a bios update.

After the update when booting windows i got the error message INACCESSIBLE_BOOT_DRIVE which somehow resolved it self through the windows recovery tools.

When booting Ubuntu I get dropping to shell message, along with error message telling me that the UUID of my boot doesn’t exist.

I just tried to use the boot-repair disk however it doesn’t show the recommended repair option for me hence I took a log http://paste.ubuntu.com/p/NCVjn5g9jp.

I read on a forum (cant find the link right now, I’ve read so many posts this week) that this might be related to the storage controller settings in BIOS. A user found a solution changing this setting to AHCI. Mine is set to RST right now although when trying to change it i’m prompted with a warning that it will delete all my data.

Any help would be very appreciated!

Lenovo G560 F1/F2/F12 won’t let me get into BIOS

Lenovo G560

I’ve replaced the HDD after it died to an SSD, it won’t let me boot from anything, not to mention it won’t let me get into BIOS. From all I found on google they suggested hitting F1/F2/F12/Delete (even tried the F keys with FN) nothing happens it goes into PXE, exits it and says no device.

I am clueless as to what to do with this laptop, it won’t boot to anything, although placing he dead HDD back in showed that it can’t “talk” to it and gave an error.
