Windows 10: Which route do I take to deal with old broken Win7OS Windows7pro Dell latitude, to run...

As a Mac user windows is something I've never used, so I figure post a question here and see what the experts say.My situation is I have several Macs and while they all run, I do have Sql Server SS but I can't load SQL Server Management Studio SSMS and Azure Data StudioADS does run it looks nothing like SSMS so the tutorials are mostly useless as I've bought Murachs SSMS book for SS 2019.I need to get a windows machine up and access it on a network to upskill on SSMS. I have a MacBook Pro, an iMac and a Mac Pro I use for GPU compute projects so I could do this from any machine, use them

No drive found on my internal hard disk on Dell Latitude E5430.

Hello,My laptop (Dell Latitude E5430) was working perfectly till yesterday. But yesterday night, it restarted on its own and ever since, it's stuck at this screen:



Also, inside the BIOS, no UEFI bootable hard disk drive is being listed.



The UEFI flash disk option shown above is that of my bootable pen drive with Windows 10 installation copy.I googled this issue a bit and the results were as follows:

1. one thread suggested that I should run Dell's internal diagnostics to see if there anything wrong with hard disk. I did that but every component, including the hard disk one, passed these internal test.
   
   
2. a second thread suggested that I should try to remove and reseat the hard disk. I did that following Dell's user manual.
3. another thread suggested that I should reinstall my windows 10 afresh. But when I try to do so, the windows installation wizard doesn't list any drive in the hard disk. It's as if it doesn't detect hard disk at all.
   
   

In a nutshell, while the hard disk is being detected, but none of its drives is. However, the hard disk consisted of 3 drives:

1. C: with the windows' and applications' installations,
2. D: with all of my data,
3. E: which was recovery drive.

Any troubleshooting suggestions?I'm sorry I am not able to help you guys with any logs and stuff because I don't know how to get them when I can't get my Windows to boot. I'm not even sure if this is the correct section where I should be posting this thread.. I'm just so confused right now. *cry

A few weeks ago, I had upgraded (not fresh installation) from windows 10 version 1607 to 20H2. The version 1607 installation was a clean one (from scratch, after formatting the hard disk and creating new partitions).

Yes, already checked where CMOS placed. All computer should be disassembled. For now, we put it back to warehouse. When will have more free time, will try to replace CMOS battery.
Thanks for suggestions, will close this thread now.

Have you considered a broken disc?
I've never had Dell Latitude e5470 in my hands but if it's not too difficult try to (just temporarily) replace it.
