This Error 1962 issue is frustrating, but your BIOS fix guide is spot-on! For users still struggling, here’s another angle to consider—failing or incompatible HDDs**. Specifically, when troubleshooting with a 3TB 7.2K RPM 3.5″ SATA HDD https://serverorbit.com/hard-disk-drives/sata-3gbps/3tb-7-2k-rpm-3-5inch, watch for these quirks:

Legacy/UEFI Compatibility

Older Lenovo BIOS versions sometimes misread large (>2.2TB) HDDs in Legacy mode. Your UEFI-first solution is critical here.

Pro Tip: If the error persists, check if the HDD uses GPT partitioning (required for 3TB+ drives in UEFI).

Power/Cable Issues

High-RPM 3.5″ HDDs demand stable power. Try:

A different SATA cable (as noted)

Connecting the HDD to a dock/USB 3.0 adapter to isolate motherboard issues

Emergency Recovery

For data rescue, slave the drive to another system via USB/SATA. A 3TB HDD’s bulk capacity makes it ideal for temporary backups while troubleshooting.

Question for the community: Has anyone resolved Error 1962 by swapping to a smaller (e.g., 1TB) HDD temporarily? Could be a telling diagnostic step!

Worked for me as well with A Thinkstation P700.
But…the system has problems detecting certain hdds and SSDs. Dunno know why

Could you please detail the steps to solve error code 1962. I’m reading a thread that references them, but can’t find the message that has the actual procedure.
Thank you

Hello! Working at my desktop last evening I had that blue screen with message
“Error 1962 No operating system found Press any key to reboot Sequences”
Which I did, not knowing better… after that the computer came back as usual and
I kept working for a little while before turning it off….
In the morning when I turned it back on this morning it was on bios mode…
After reading your article I tried to press F12 repeatedly , I tried to type in Set up…
Since, I did not have the little square but only a line saying
No operating system found but nothing happening except a new line saying “Missing operating system”
I had all kind of issues with Windows & Microsoft 365 for over a month…
Starting by the mouse cursor that got crazy on Excel doc than on every docs…
After that I couldn’t open anymore any documents on my computer, they wouldn’t open…Than lately it is One Drive that start to act up doing anything but the good one… Taking document even If I said to leave them on my desktop (localy), taking the original instead of making a copy of it. Sometime it took me hours to retrieve it or access it, I found document that were completely (f… up)!!! sorry! about that!
I had 3 session on remote with technician of Office 365 or Windows except for the last time with One Drive, those guys does not have the same privilege to be able to talk to you or assist you on remote etc… It is only by email. and of course I had a hard time to explain them that after putting the One Drive syncing on PAUSE and still having issues, I got tired of all that and turn it off!!!! But that thing didn’t care that much about that it keep taking document away of me, to specially the one I just created and If wanted to access it again that thing was telling me to sign in in order to access those documents I just created!!!????
I am far away then a computer specialist but…|
Am I wrong to think that something like One Drive should not do that kind of thing and there is something wrong somewhere!!???
If you could help me, I would really appreciate….
I really need that computer and is content, ( 2 years of work)….
Anything, I could do or I lost everything…\
thanks anyway!!!

This didn’t work for me. It’s a brand new hard drive and I’ve never had this issue before. Any suggestions?
