Invalid Partition after failed Factory reset - M3470G desktop

So did a factory reset to Win7 to clean everything up. 100% backup was done, then reset hung at 99% on the re-install for 2 days. Had been updated to Win10.
Did what I shouldn't have and manually powered down.
Now invalid partition table error at boot up.

Tried USB media stick for a Dell Win7 computer that I had and got the start-up / boot screen, but it did not see my HDD - asked to load the SATA controller driver.
I did check the Bio and it is there so I know that the Bios sees it.
I tried the USB Win7 Media a few times trying to figure this out and now that seems to have a corrupt BCD file as well and now instad of the Windows startup/recovery screen it goes to a startup error screen.

I can get the disks I guess from Acer ($20) or try to use the free Win10 download to re-boot, but wondering how to fix the partition issue so I can get to some kind of recovery mode?

Or I did also download the AMD motherboard driver for Win10 if it asks me to load a SATA controller driver like the Win7 Media did.

Any help would be appreciated.
In the meantime I will be trying the Win10 and AMD Motherboard drivers just to see what happens and will keep people posted.

so...now has it windows 10 or windows 7?

So it has neither now I guess. Reset to factory win7 failed so I guess still win10? But I can’t reboot due to the invalid partition.

And as as I said, When using the win7 usb boot it did not see the hard drive.

Will be attempting a win10 clean install with new ISO download later tonight. If I get the same message and it doesn’t see the hard drive I have the AMD win10 driver that will hopefully suffice.

Or if there is a way for me to get back to the Acer factory reset option, I would select a clean install. The failed attempt was trying to do a backup and maybe I didn’t have the HDD space. Should have just done a clean install but was trying to keep a version of MS Office 2010 from being lost as it was a preinstall and I don’t have the product key.

thanks for any insight.

if you want to try a factory reset, try Alt+F10 keys at boot but i doubt it will work.

about windows 10 not finding your HDD, can be the AHCI or RAID drivers missing, if you have it, you will able to load it during installation.

Thanks will try. But yes doubtful based on my situation.

it was Win7 reinstall that couldn’t find the HDD so I’m hoping the win10 will “see” it and if not I do have the drivers (I hope) from the AMD website.

IronFly

i'm quite sure that windows 10 will find your HDD.

RockOn

Didn’t have to do the win10 install.

Thanks for prompting me to retry the Acer reset again. It did come up and a clean install on win7 worked vs trying to save a backup.

All security updates done and up to date. Home network including backup drive and network printing good to go.

thanks!
