Hello,
This is a long shot, perhaps, but can anyone tell me where I can download the latest BIOS for an ancient (purchased in 2013) S7-191-6447?
Many thanks! LN

Which BIOS version is installed? Do you have issues and why do you want to update the BIOS? The latest version 2.19 is available on the support site for your model.

Thanks, Wascas. I've upgraded. I was having difficulties upgrading from Windows 8.1 to 10, and am hoping this will help.
It's not too likely to help, what issues are you having with the upgrade? We might be able to help with that.

Thanks, billesy, for your offer. Yes, I am indeed having trouble with the upgrade from Win8.1 to Win10. The first time I tried, the install got stuck on 2%, not even getting to the first reboot. I upgraded the BIOS and the drivers and tried again. The install process got through the first reboot, but got stuck at 10%. Both times, the error message was the same. See below.
Suggestions appreciated. LN

The installation failed in the SAFE_OS phase with and error during APPLY_IMAGE operation
Just in addition to the above, as I've done a clean install from Win-8.1 to Win-10 Pro on a similar 3rd Gen Intel HD Graphics 4000/NVidia GT640M gpu laptop but not on a Raid 0 array, and it worked out perfectly.
Make sure that the Aspire S7-191-6447 bios Version:2.19 is installed, then do a Clen Install of Win-10, but and due to the Aspire S7 which has its Win-8.1 OS installed in a fast RAID 0 array of two 128 GB SSDs you have two choices, either do a Raid 0 clean install of Win-10 or just install the win-10 on 1x 128GB LiteOn 128GB SSD drive. For the clean install in Raid 0 array look at guides on how to do that on the web.
The errors that you are getting with the upgrade is because the Aspire S7-191-6447 is installed in Raid 0 array and there are problems like below with the upgrade.
Typically that error is generated by an incompatible driver that fails when the installer tried to load it. Remove all peripherals, uninstall any antivirus, verify all drivers are updated to the latest for W8.1 and perhaps disable any printer, audio and video drivers. Also sometimes it will work better with a clean install instead of an upgrade, but that would mean you would need to reinstall all your apps and data...

Thanks for your input, StevenGen. I had already updated the BIOS to 2.19, and updated all my drivers. I'll check the drive for errors and look into how to restart the Windows update service. (Is the latter even possible now that MS has discontinued support?) I'm not sure how to approach the RAID 0 array business. I wasn't aware of that as a factor. I'll look into it. If you have ideas as to where to start, I'd appreciate learning of them.
Best wishes.

Hi billsey,
Thanks for your suggestions. I've been using the (oddly named) Media Creation Tool to install Windows 10 on this old Acer. I chose the option to delete all programs and personal files, so I guess that's a clean install. I'll try again, after taking all the precautions you mention.
Best wishes.
Yeah, that option doesn't actually delete everything, it moves some stuff into a Windows.old folder and reuses the existing drivers. If you boot from the flash drive that Media Creation Tool makes for you, then do a new install and wipe all the existing partitions at the screen where it asks you where to install it does a full clean install.
