Problems upgrading Acer Aspire One D270-28Dws
I have an Acer Aspire One D270-28Dws. After seeing a number of instruction videos on YouTube, I decided to upgrade the RAM from 1GB to 4GB and the original 320GB HDD to a 120GB SSD. I had been running Windows 10 Home (upgraded from Windows 7 Starter) without problems, but was adviced to do a "clean" install, so I used Microsofts Media Creation Tool to create a bootable USB-stick with Windows 10 Home. I followed the instructions from the videos and the changeout of the RAM and the HDD went as planned. I plugged in the USB-stick, went into BIOS and altered the boot order and restarted. Instead of the expected installation, I got a message saying "No bootable device -- insert boot disk and press any key". I tried copying the contents of the USB-stick to an external hard disk and tried booting again, but no improvement. When I went back into the BIOS, I also noted that it stated only 1GB of RAM. I still have the old hard drive unaltered, but my hope is that I don't have to put it back again, since I upgraded to improve performance. The CPU is an Intel Atom N2800.
Any advice on how to proceed?
