No operating system detected Solved

Question

Hello, I had an issue with my PC recently, my internal 1 TB hard drive crashed and I had W10 on it. So I removed it to replace it and when I try to install it on my SSD, I plug in the USB stick with the W10 ISO but nothing happens. I get this message after the Acer BIOS: No operating system detected. I don't know what to do anymore. I've changed the BIOS to boot from the USB stick first but nothing changes. I checked, I have the correct version of W10 on the USB. I changed the SATA settings in the BIOS but nothing changes, I don't know what to do anymore. Thank you.  Configuration: iPhone / Safari 11.0

I had a similar problem with an Asus laptop after changing the HDD; I had to disable something related to UEFI blocking in the BIOS to be able to reinstall Windows with the USB, but I can’t quite remember. If it's not resolved by tomorrow noon, maybe I can tell you more because I'm not at home right now.  -- Experience is a lantern that we hang on our back and that only illuminates the path we've traveled!!!

Hello,  You need to press a key to boot from the USB drive. What is the model of the computer? Did you create your USB drive using the Media Creation Tool?  See here for explanations: How to boot the computer from a USB drive  -- Please press any key to continue the disinfection...

You need to enter the BIOS and select your USB drive as the first boot option; otherwise, it will boot from your SSD. Then, set the SSD back to first boot once the installation is done; otherwise, it will boot again from your USB drive if, like me, you only have one boot option by choice.

For me, your BIOS choice is good, but I just saw this: https://www.asus.com/fr/support/FAQ/1030858/  I hope this helps you...
