Not found in EFI settings list
I attempted several times to upgrade for a win 10, but it didn’t work. Eventually I made a bootable ISO, used Rufus to write it onto a USB stick, and installed the OS on my SSD. While running from the USB, I had to switch the boot mode from UEFI to Legacy. After installation, I tried reverting it back to UEFI, but if the SSD isn’t recognized as a boot device in UEFI, it only works in Legacy mode. The system is functioning properly. Are there any reasons you’d need to switch back to UEFI? Just curious.
It seems you haven't set up Windows in EFI mode. Make sure your BIOS is configured for EFI only. Your USB or disc copy of Windows must also support EFI, which Rufus handles properly. During installation, choose the correct drive and remove everything on it—especially the C drive. Then click New - Apply, and you should see available partitions on your C drive. Pick the largest available primary drive and proceed.
Format the SSD for GPT creation. Activate UEFI settings. Boot using the USB drive. From the SSD, create a fresh partition with the Windows installer. After setup, four partitions will appear.
You can verify if your ISO supports EFI by checking the boot options during installation. If you need to switch to EFI, consider it an upgrade from legacy—EFI offers better performance and features, though it may require a compatible BIOS and hardware.
You shouldn't use Rufus if you wish to boot in UEFI mode. Simply format the USB to FAt32 then copy paste everything from the ISO to the USB drive and it will boot in UEFI mode. As for the benefits of UEFI, quite simply a 6 second boot time is all you really need to know, theres other stuff to but the main reason to use UEFI mode to install Windows is for fast boot.
Your board, when all drives are forced to boot in EFI mode, will treat your flash drive as a bootable item in the startup menu. If you've already set up Windows in legacy style, switching to EFI is relatively simple. You'll experience quicker boot times, faster sleep and shutdown, plus quicker wake-up from sleep and other improvements.
Thanks guys... re-installing Windows 10 should work fine, but getting updates and drivers online will be tricky due to the slow internet. I’ll keep using the old boot method until I need to reformat the system again.
