I’ve had zero luck going with the Generic x86-64 on a Lenovo Tiny M92. I use the ubuntu live approach and balenaetcher to copy image over to the HDD. All goes well, proper partitions seem to be made on the Tiny, but as soon as I reboot, there’s the “Error 1962 No Operating System Found”! Tried a whole bunch of BIOS combination settings (compatibility mode etc) nothing seems to work. Has anyone had better luck with these devices?
It took me ages to install a non windows OS on this thing.
It is working fine now on debian 11 with supervised. I had to update the BIOS. Youtube showed me how.
EDIT sorry mine is a m72e not a m92, but it sounds like the same problem, and probably the same solution.
Does the Tiny M92 support UEFI ? HA OS requires UEFI.
Yeah that is what the bios update was necessary for, to get UEFI boot support. I think this was the video BIOS Update on Lenovo ThinkCenter E72 3493-KAG - YouTube . Having wiped windows, I had to create a usb boot device like in the vid.
Yes, it does support UEFI, and yes, I did the BIOS update to the latest. I can surely install Debian 11 and go supervised, just annoyed the HAOS thing is not working out…
Did anyone get this working?
I was previously running debian 10 and supervised install, but saw generic was available, so wiped the machine and 3 days later still pulling my teeth out.
I miss my home assistant 
Using an RF remote to open the garage door, feeling like a pleb lol
As above my m72 is fine running debian 11 and supervised.
Hi,
I don’t know if you have solved your problem but there is a workaround to the boot problem, follow this tuto on youtube:

I know this is a reply to an old post, but it may help people searching for answers as I was.
I have successfully installed Home Assistant on a Lenovo M72e-Tiny computer.
I was having trouble booting up until I used this method at the bottom of the installation instruction:
Use the “Disks” utility from the live USB to find the drive name and then use the terminal to issue the efibootmgr command.

Dropping this here in case it helps anyone.
- Decided to get cheap Lenovo m72e (tiny) as my RPi3 was straining.
- Installed proxmox (but it could have been any linux based OS) via USB but ended up failing to boot with “Error 1962 No Operating System Found” - so proxmox was installed - but the BIOS wouldn’t hand over to GRUB to boot it.
- Tried flipping BIOS settings w.r.t. UEFI, secure boot, etc… no luck.
- Tried clearing CMOS by opening it up and changing jumper - did not even start up (no video signal)
- Moved jumper back and same problem (corrupted BIOS - had to reconfig)
- Then tried BIOS update - get update files via Lenovo Site (replaced the 61 w/ 57) to be https://download.lenovo.com/pccbbs/thinkcentre_bios/f4jt57usa.zip (did not try 61 as 57 ended up working)
- Downloaded FreeDOS full .img file and used balena etcher on my mac to write to USB stick.
- Opened the drive on mac and copied the f4jt57usa directory onto it.
- Booted the Lenovo m72e with this (not installing FreeDOS - just go to prompt)
- Read the readme.txt in the f4jt57usa directory - basically in DOS - cd into directory and run FLASH2.EXE FIRMWAREFILENAME
- To get back at the man - I also updated the boot image to something more… satisfactory (8kb BMP)
- BIOS update ran and machine restarted.
- Removed FreeDOS USB stick - and blam - BIOS saw GRUB and proxmox started up.
