"no operating system found" on reboot post-install

[liverpj]

Hi

New to theforum and although I’ve been using lubuntu for a few years now I’m a prettybasic user, so please bear with me J

Background:
· Laptop:Samsung from c.2010
· Ihave installed a new 120GB SSD and wanted to install a fresh version of Ubuntumate with no other OS
· Afterinstall when booting it says “no operating system found”.
· Liveversions work aok.
· Whenchecking the SSD using a live version of both Ubuntu and Mint mate the OSshowed up.
· Itried a fresh install using Mint Mate, with the same result, followed by multipleattempts with both Mint and Ubuntu mate

What I havetried:
· Changingthe boot order
· Lookingfor something referencing UEFI/EFI (which I don’t really understand). In BIOS(?)there is an option called “Legacy OS Boot” which can be disabled/enabled; “SelectEnabled to attempt Legacy OS Boot only. Select Disabled to attempt EFI Bootfirst, Legacy OS Boot Second”.
· InstallingMint mate and choosing the “something else” then trying to partition as per onlineinstructions – there ended up being quite a lot of partitions I didn’trecognise and no UEFI / EFIpartition options.
· Wipingthe SSD using; sudo wipe /dev/sda1 [the only other drive that seemed to showwas the flash drive]

My laptopis still wiping… now on its 3^rd pass (IDK how many it will do)

It was solong ago that I installed lubuntu that I can’t recall the process, but I’m sureit worked without issue.

Any ideas? Orany decent noob guides which include advice on how to partition post install? Thereseem to be so many average guides now that it’s hard to see the wood for thetrees.

Cheers.

A Duplicate post without the conjoined words - mods if it's possible to delete the first post that would be amazing! Not sure what happened when I pasted.

Is there an OS installed on another drive of this computer and if so, what?
Is/was there an EFI partition on another drive?
When you install, do you select the Erase disk and install option or failing that, leave the default in the install.
Not sure what instructions you followed but, there is very little reason to create more than a / (root filesystem) partition and a /home or /data partition.

Thanks for replying.

As far as I know the only OS was Lubuntu until I removed the HDD and replaced it with a new SSD - at which point there was no OS.

The laptop originally shipped with Vista.

Idk if there was an EFI partition on the original HDD - is this something I'll be able to check by plugging the HDD into a Win10 laptop with a dock and USB?

I've tried most of the variations of install. But yes I did try the Erase disk and install option, which still gave me "no operating system found" on restart.

Re the partions; the guide I followed when I first installed Lubuntu ages ago broke down exactly which ones and what size in relation to the memory. Iirc they were just the one you listed.

The reason I'm after an idiots partion guide is it looks like some people online seem to have had (and I guess solve) the no OS error in relation to dodgy partitioning.

Cheers.

If from 2010, it will be BIOS only, no UEFI.

Apple used early version EFI when it changed to Intel chips. But PC only changed to newer UEFI when Microsoft released Windows 8 in 2012. A very few Windows 7 systems just before Windows 8 may have UEFI, but that vendor was probably making sure his UEFI worked.

With BIOS, no operating system found would normally mean grub was not installed to MBR of default boot drive in BIOS drive settings.
If you used something else install option and did not install grub to MBR, drive like sda, not partition like sda1, then system has no boot loader in MBR.

May be best to see details, use ppa version with your live installer or any working install, not older Boot-Repair ISO:
Please attach link to the summary report, the auto fix sometimes can create more issues.
https://help.ubuntu.com/community/Boot-Repair

Boot-Repair may be able to fix it, just by installing grub to MBR. But usually best to have someone review report to make sure. Occasionally Boot-Repair does not make correct or best choice automatically. If multiple drives only use Boot-Repair's advanced options.

I don't have the laptop with me at the moment, but that is really helpful.

Hopefully by tomorrow its stopped wiping and I'll be able to run through those points.

I didnt install grub.

Since your machine offers EFI/Legacy settings, it may have an early EFI version, pre-secure boot (I have a Lenovo like that, which boots fine ether way). Set the EFI to preferred, and ensure you have an EFI partition (300M, FAT, ESP flag) and your install media should boot and install in EFI mode. Without Windows present, the disk partitioning does not even matter, but gpt makes life easier if you want more than four partitions. Then the reboot should also be in EFI mode. Didn't see you list an EFI partition, in the earlier post, so we'll see what the boot-repair report says.

Boot report above. Sorry just realised you said paste the link... http://paste.ubuntu.com/p/gwSRZXz5Pt/ http://paste.ubuntu.com/p/gwSRZXz5Pt/plain/

BIOS is EFI-compatible, and is setup in EFI-mode for this live-session.
SecureBoot maybe enabled.

So my BIOS is EFI-compatible it seems.

My next steps are:
1. Reinstall Ubuntu using the 'something else' option.
2. Check partitioning is correct
3. check grub is installed / install grub
4. go into BIOS and (in my options)

Select Disabled to attempt EFI Boot first, Legacy OS Boot Second

The bit I'm unsure of is;

Set the EFI to preferred, and ensure you have an EFI partition (300M, FAT, ESP flag) and your install media should boot and install in EFI mode.

Does the install media mean the version of ubuntu downloaded onto the USB? If so is there a way to verify that? Or am I miss-understanding?

Thanks,

"Install Media" would mean the DVD or USB with the Live Ubuntu installer.

BIOS options vary a lot between manufacturers. If you have an EFI capable system, EFI booting may be the priority but if you want to install EFI, you should be able to disable Legacy/CSM in the BIOS.

It would be simpler if you want EFI to create the EFI partition prior to the install. You can use GParted which is on the Ubuntu install DVD/USB by simply opening a terminal and typing: sudo gparted
This should show /dev/sda in the main window. You currently have only one partition taking up the drive so resize/shrink it by highlighting it in the main window then clicking on the Partition tab at the top and click the Resize option. Shrink to 200-500MB. When that finishes, again with this partition highlighted in the main window, click the Partition tab and then the Format to option and select FAT32. When that finishes, again click the Partition tab and this time select the Manage Flags option and check the boxes next to boot and esp.

You should then be able to boot/install UEFI. I would suggest reviewing the Ubuntu documentation at the site below, particularly the General Principles and Identifying if Computer boots in UEFI mode. You can skip over the windows dual boot info as it does not apply in your case but there is a good bit of useful information on UEFI with Ubuntu specifically.
