Windows 10: An operating system wasn't found, even though I have been using this computer for months.

Hi!

My win10 installation did work badly. I tried to make a new clean installation wich should delete everything but the installation couldn´t complete due to an error.

Looks to me that there´s no operatings systemon the disk and the disk is the only drive to select for boot order in BIOS.

Have I lost my ASUS Eee PC 1225B?

Do I have to install a new disk with the Windows 10 in the PC?

OP - An operating system wasn´t found

 

When booting, i get a dashed line. After reseting, i get "An operating System wasn't found, press any button to reset". Once I do that, it boots into Windows 10.
