OPERATING SYSTEM NOT FOUND - After Fresh Install

nicthegarden · 2018-09-27 15:19

Hi there ,

I did install the OS with the Live CD.

I did remove all partition before the install. Installer went super great and partition was created by the Partition utility automatically.

Once it's finish , the system won't boot on the HDD. and it keeps telling me that OPERATING SYSTEM NOT FOUND.

Thanks for the support

after validating the installation by booting with Gparted, the boot flag was not existant on the HDD.
maybe it has to be with the installer.

system is now running properly with no issue at all

We would need to investigate this issue in more depth. Please, would you post some more information for us to be able to reproduce that ?
- What Q4OS installation media did you install from ?
- How exactly did you remove partitions or perform some disk re-partitioning before installation start ?

Anyone else noticed this issue ?

I haven't noticed this, although I have not installed on an empty system in a while but will check hopefully later today as I have another system I have to set up for someone.

Versoin 2.6.

There was a Windows Partition present on the disk.

The wizard installer at first wiped everything but did not do anything.
Since it didn't not work I deleted all the present partition on the HDD.
Installed the system with the wizard, same behavious. Boot flag was not present after the reboot.

I had to boot on the ISO again, and then put the Boot flag. Not a biggy.

@nicthegarden
Thanks for the valuable info, it seems to be a quite significant installer bug really. We will try to reproduce that and post a feedback as soon as possible.

@nicthegarden
The issue looks to be hardware dependent, as we are not able to reproduce it in Virtualbox so far. The installer really doesn't set the "bootable" flag on a fresh installation, but the VM boots fine independently of bootable flag set or not. As the grub is written into the MBR, a bootable flag shouldn't be needed to properly boot the system. The only exception would be, if BIOS checks partition table and looks for a bootable flag. In such configuration, the BIOS would bypass MBR code and boots from the marked partition itself.

A couple of questions:
- Did you command the installer to write Grub into the MBR throughout the installation process ?
- Would you post motherboard type ?

I (a Windows user) have just installed q4os-2.6-x64.r2.iso fresh to 60GB SSD for a tryout and have a similar problem,
Install from ISO went fine, used trinity desktop with the full version to the SSD which used to have a windows install.
Repartitoned to linux using your builtin wipe/repartition. M/B Gigabyte Z77-DS3H + Intel i3 + 8G RAM.
Tried to boot from SSD, POST went as usual, immediate blank dark screen with a slow flashing cursor, nothing else. Frozen.
CtlAltDel= no action. Hard reset essential.
This screen appears instantly after POST so its finding enough boot information to avoid a crash but just grinding to a halt.
If you want me to try anything with this install before I wipe, I know nothing in Linux so you will have to spell it out I'm afraid!! Thanks C+

@ChasG
It seems to be a different issue. Please try to tap 'Esc' key immediately after switch on and report back, if the Grub boot table appears on the screen. If so, you could try to select and boot Q4OS in failsafe mode.

ChasG · 2018-10-05 10:09

Thanks, OK tried that , no action same blank with cursor.
Rather oddly CtlAltDel now soft reboots!

Well, try to boot the live cd, run Gparted from start menu and post the disk partitioning schema and boot flags. A screenshot would be most helpful.

q4osteam · 2018-10-05 10:51

You could also try to install Q4OS Centaurus testing version, see https://q4os.org/downloads2.html , and report back if it boots. Anyway, thanks for reporting.

ChasG · 2018-10-05 11:21

I assume Gparted is a run command:
OS tried to connect to web. Didnt bother...
Ran from command prompt:
bash: Gparted: Command not found.
I assume this means your installer has not put it on this install?

ChasG · 2018-10-05 11:24

Correction this is the live (USB) Q4os running..

No, you will find Gparted application in the live cd/usb - Start menu.

Alternatively you can run it from command line:
$ sudo gparted

Another way to check disk partitioning and flags:
$ sudo parted /dev/sda print
and paste the terminal output of the command.

Trial is not on a connected unit. In a different room!
ran Sudo etc so took photo ,
Looks like installer has not made a bootable SSD?

ChasG · 2018-10-05 12:49

Used your sudo*
trial is in another room and unconnected so took photo
looks like installer failed to make a bootable SSD

Well done, now try to create the boot flag on /dev/sda2:
Run GParted > right mouse click on the /dev/sda2... line in the GP window > Manage flags > check "boot" box > Close > Try to reboot installed OS
Post back the result.

ChasG · 2018-10-05 14:24

OK thanks.. Done but result hasn't changed the SSD boot behaviour.
I rechecked Gparted again afterwards and the boot flag is still set.

OK I installed an old 20G HDD and installed to that - all fine (but slow!) so the USB installer medium is ok.
Went back to the SDD and reinstalled to that, exactly the same steps as before - only diff was I chose the simpler desktop package setup
to time save really. Installation fine this time.!
Thanks for taking a look at the problem.
