Question Finally got back to the Lenovo P520 and now getting the "Error 1962 no operating system found".

[ch33zw1z]

Yes the primary problem now is no video at hardware level. The original issue was can't boot to Windows. That needs to be fixed before I can do anything. I am getting a single beep at startup now. I have booted with no drives installed and only 1 DIMM installed. I'll try removing the CMOS battery and booting that way.

Single beep means the GPU is still installed. Did you try to force the POST error by removing GPU and memory?

 

[jamesdsimone]

Additionally, check your cable for bent pins, try a different cable (as suggested earlier).

Which cable?

Not yet I'll try after dinner. Been screw with thing all day.

 

[ch33zw1z]

Which cable?

video cable

 

[jamesdsimone]

video cable

Tried 2 different ones. I pulled the video card and left one DIMM in and it did not give the proper beep codes just a single beep instead of 2 long beeps followed by 3 short beeps. I tried twice. I pulled the one DIMM and it gave the proper memory not detected beep codes.

It really sounds like there's an onboard GPU on this pc. Unfortuntely, so far, I don't see any jumpers in the manual that could force onboard / expansion (aka discrete) as default. That used to be a thing, but it's supposed to auto-detect now.

What GPU did the pc come with?

If you don't mind reinstalling the Ubuntu drive and booting up to it, there's a couple commands to run.

Three things to look for: BIOS Version, CPU model, and GPU's that Ubuntu can see.

*also - what's the Machine Type for this pc? Should be listed on the cover somewhere. It will be 30BE or close to that.

1. sudo dmidecode -t bios -q

This command will list your BIOS information. Looking for what BIOS version it's at.

2. sudo lshw

This command will list hardware, just looking for what GPU's the system sees from Ubuntu's view.

also: sudo lshw >>

Using the >> can save the output to file

here's a nice link for other lshw commands: https://linuxhandbook.com/lshw-command/

You can use sudo lshw -C memory to see BIOS information as well.

What GPU did the pc come with?

It did not come with a video card. It is a barebones workstation just the case MB,CPU and PS. I added everything else, micron ECC memory, storage and video card. I just use an old 4850 while configuring it. I'll add a new card when I'm done. It does not have onboard video. This is the computer as far as I can tell.

I can plug the Ubuntu drive back in no problem. I just pulled the power and SATA cables.

Here's an interesting link I found at the lenovo forums: https://forums.lenovo.com/t5/ThinkStation-Workstations/No-display-output/m-p/5064487?page=1#5250329

Basically, this guy used an old VGA and uEFI system didn't like it so much.

You've beaten this thing to death for sure, so kudos to you for your determination. This is all steps I take when performing PD, and usually it points to a particular device pretty quickly. Sometimes tho, it can be a PITA, like you're seeing here. What you're doing will come in handy when going to the vendor, as they will likely ask you for more information. It's also handy to pick up some tricks for future PD

Edit: Regarding the link you posted : https://psref.lenovo.com/syspool/Sys/PDF/ThinkStation/ThinkStation_P520/ThinkStation_P520_Spec.PDF

Yea, this is the same link I had been looking at. The problem here is that some vendors and Lenovo will go to this document and say "your GPU isn't supported". We all know that devices that aren't on the list are likely to function just fine, but sometimes vendors get finicky about the list....and more-so Lenovo themselves. If you go to return, don't tell them anything but what they ask

The output of the commands

There are pages so I'll have to rerun it and send it from the Ubuntu.

I hear that, don’t need all of it, using the more specific commands I listed make the output easier to work with

 

[jamesdsimone]

Sooo it did turn out to be something stupid. Seems these Lenovo workstations require UEFI capable video cards to work so when I set the BIOS to UEFI only the hardware video no longer worked. And apparently the default BIOS setting must be UEFI only since setting the CMOS did not fix the problem. Guess the BIOS is not smart enough to detect that a non UEFI video card was installed. Now back to the original problem.

 

[bba-tcg]

I gave you some things to look at earlier in the thread...

 

[ch33zw1z]

If you’re back to no OS found, that's great, definitely fixable. I'm still curious what CPU you have. The fact that pulling the GPU didn't fail POST makes me suspicious that the CPU you have also has a GPU on it.

So no OS found is the current problem?

Did you follow the HMM's CMOS clear procedure? Or boot without the CMOS battery installed?

All 3 of the video cards I tried were apparently not UEFI ready. I installed the RX 6800XT I was planning on using that fixed the problem with the hardware video. I usually use a place holder card when configuring a system and install the video card later since they are so big. I gave up on the Windows install and just reinstalled Windows which seemed to install fine. I have Windows 7 up and running on my NVMe drive. I had spent a week configuring and installing software so I have to re do all of that. I had hoped to avoid having to do that and never figured out why the computer couldn't see the Windows install. One more question, I'm using generic Windows 7 NVMe drivers, should I install the WD drivers or leave it alone?

My question about CMOS clearing is more centered around this pc working at first, then a setup change rendered your VGA unable to display POST / setup.

Also, you've gotta post the CPU model

Re win 7: IMO, you should move onto a newer OS.

The current setup is a Lenovo P520 Thinkstation with a Xeon W-2145 4x16 Micron ECC P2666 RX6800XT 2x WD SN770 1TB NVMe Blue ray drive 4TB Seagate E.3 drive 5.25 SATA hot swap tray less hard drive rack. I'm going to add a Micron 2TB SSD when I finish loading all the data from my old computer.

I'm not sure why there was no error code when I pulled the video card but the CPU does not have video. I cleared the CMOS twice with the jumpers and pulled the battery for 15 minutes. I never booted without the battery installed. I used 2 4850's and a GT710 which is what I have laying around before putting the RX 6800XT in. Guess none of those cards support UEFI. When I installed the RX 6800XT and got back into BIOS it was still set to boot UEFI only so that is why it did not fix the problem. I set it back to auto/legacy first. I still don't know why the system stopped seeing the first install of Windows. I gave up and reinstalled. I'm concerned it might happen again. I'll image the boot drive when I'm done just in case.

Why do I need to change OS's? What exactly does that do for me? I currently have in operation 9 desktops and 5 laptops, 3 Win10, 9 Win7 and 2 Linux. Win10 is malware infested crap. Win7 runs everything I plan on running. I have it running on the NVMe drive. I'll install a second OS(probably Linux, maybe 10 if have to for a game I need it for)at some point on the second one.

If that's the cpu you have, then it definitely is odd that you wouldn't receive POST errors when the GPU was removed.

Regarding the setup config, if CMOS was cleared, then it is a problem IMO that Lenovo wouldn't clear the settings back a more compatible setting.

Windows 7 was end of support in 2020. Not only are there no more security updates for it, but eventually software vendors will stop supporting it as well (if they're even still supporting it now).

I agree but it's a workstation meant for business so they didn't design it to be upgraded to a gaming computer or to be changed at all for that matter. Still having the default BIOS settings to the least compatible settings is kind of BS.

I don't care, I not concerned with support or security updates. I do all my online stuff on Linux. This computer will not be on any sites I'm worried about, streaming Netflix, Amazon and Hulu and my own network is about all. I don't do any online gaming and I won't even be getting email on it. I can always install a 3rd party firewall too. As for games, you don't understand the gravity of the situation. I'm replacing a FX8350/7970 system I've been using for literally 10 years. It wasn't a too bad a system in 2014 but really limits quality setting especially with high resolution modded games. I doubt I'll be playing anything newer than 5 years old for a long time. I have a whole library of GOG games I haven't played. Ha I can finally play Crysis 1 at max settings then maybe Metro series and Deus Ex.

I'm not sure what you mean here. Plenty of business machines come with CPU's that have GPU's onboard. It's the most common option I see in the field. The P520 is built for graphics design work, hence all the quadros in the supported GPU list from the psref page, and the Xeon CPU, and the ECC Memory... Lenovo designs it to be changed according to their support device list only.

None of which explains the behavior with the GPU removed.

So your windows 7 boxes don't get IP's?

Additionally, if you're worried about what drivers to use for your new hardware on an older OS, a newer OS removes that concern as well Running an unsupported OS is always YMMV.

Checked driver support before I bought the computer, Windows 7 is completely supported. MSI has complete support for AM4 boards. This workstation came out 7 years ago. Except I can't figure out what the driver for the SD card reader is, kind of annoying.

IP's, as in IP Addresses, as in network connections.
