HP EliteDesk 800 G1 Tower PC

I have a HP EliteDesk 800 GI TWR.  The BIOS presently is 2.77.  There does NOT seem to be an upgrade for this BIOS.  2.77 will NOT allow me to run the current version of Windows 10.  I know I may have to get a new computer, but I was hoping to get a little more life out of this one with a BIOS update until then.  Anyone know of a working BIOS that will allow me to update Windows 10 for the time being?  Thanks.

Hi:

 

Have you tried clean installing W10 22H2?

 

Download Windows 10 (microsoft.com)

 

Sometimes that works if an in-place upgrade won't.

 

I have no idea why your PC can't run W10 22H2.

 

I am running W10 22H2 on a similarly equipped Dell Optiplex 7020 MT with an i5-4590 processor.

 

I'm running W11 on a two-model series-older than the 800 G1, HP 8200 Elite CMT.

 

Make a system image and bootable rescue drive with the free Macrium reflect utility before trying to clean install W10.

 

That way if it doesn't work you can go back to where you are now with relative ease.

 

Macrium Software | Reflect Free Edition

 

You want the software on the left side of the page under the Backup at Home section.

I use Acronis and back up all my drives on a regular basis.  I also have at least one clone of my drive.  So are you saying to just download and fresh install the newer Windows 10 and see if my machine runs with it?  If not, I have the clone to run with if it doesn’t.

 

As far as the clean installation.  Is that a situation that, if it works, I need to reinstall all the software?  Rather than an upgrade of the existing system?  Just curious, because that is a time investment and I want to know before I start.

 

thanks for replying.

You're very welcome.

 

Yes, that is exactly what you should try.

 

Clean install W10.

 

Then you will have to reinstall all of your programs and files, and yes, depending on how many programs you need to reinstall, that could take a considerable amount of time.

 

You'd have to do that with a new PC anyway, so you may as well try it on yours first if you really don't want to buy a newer model.

 

I've had a few stubborn PC's that at one time or another would not do an in-place upgrade to the next build of W10.

 

I never had an issue with a clean install not working.

 

While I cannot 100% guarantee it will work for you, it has an excellent chance of working.

 

That is why I recommended that you have a plan in place to re-image the drive to where it is now in case the clean install doesn't work either.

 

I highly doubt HP will be releasing any future BIOS updates for the 800 G1 model series.

 

The last BIOS update I got for my Dell 7020 was from 2019.

 

I wonder why HP removed BIOS v 2.77 from the 800 G1 support page?

 

The latest one now showing is v2.71.

 

Good luck,

hi

there seems to be another update
but if hp remove them, there must be a reason

https://ftp.ext.hp.com/pub/softpaq/sp103501-104000/sp103785.html

 

TITLE: HP Business Desktop System BIOS (L01)

VERSION: 02.78 REV: A PASS: 1

PURPOSE: Critical
SOFTPAQ FILE NAME: sp103785.exe
DESCRIPTION:
This package provides the HP Business Desktop System BIOS for supported models
running a supported operating system

https://answers.microsoft.com/fr-fr/windows/forum/all/ecran-bleu-votre-ordinateur-a-rencontr%C3%A9-u...

 

HP Support Assistant let me know that a new BIOS version from April 2020 could be flashed. I tried the automatic update but arrived at a page all in English, I gave up continuing for fear of not understanding the procedure and making an irreversible error. The file SP 103785 corresponding to the flashing of the BIOS is saved in my local disk at the location SWSETUP I think it is about HPQ Flash application but I dare not launch the procedure without being assisted by an expert.

HP still has the v2.78 BIOS update file on the ftp server, but I still don't know why they removed that one and 2.77 from the 800 G1 support page.

 

https://ftp.ext.hp.com/pub/softpaq/sp103501-104000/sp103785.exe 

 

On the HP dc7xxx, 8xxx Elite, Elite 800 G#, 6xxx, and Prodesk 600 G# model series, you can run the BIOS update exe file on any PC safely because the first thing it does is to open an info page to provide instructions on the various methods to use to update the BIOS.

 

I always use the F10 setup option which uses the DOS flash files in one of the folders that appear after you run the exe file.

 

You simply format a USB flash drive with the FAT32 file system, copy the contents of the DOS flash folder to the USB flash drive, restart the PC, press/tap the ESC key to get access to the F10 BIOS setup menu, select the File tab>Flash System ROM command from the menu, and select the USB flash drive.

 

The PC 'sees' the BIOS files on the flash drive, and you follow the on-screen instructions to update the BIOS.

 

You don't even need to have a hard drive installed to update the BIOS that way.

 

However, I would not recommend updating the BIOS since HP has removed the file from the support pages.

 

I don't think that updating the BIOS would solve the problem as to why W10 won't in-place update to the latest version.
