Hello. I recently build my very first PC. It worked, I made an USB bootable and installed windows 7, just like i would with a disc. I then installed first few games, drivers, and programs, and then deleted the files on the USB. I then turned the PC off, and started it again. Problem is that it doesnt want to boot now. It tells me no bootable device is avaible. I found that weird, as i had just installed windows 7 and have been playing the games the night before, so thought it had something to do with the USB. However i reinstalled YUMI on USB, made it bootable again with Windows 7 installer, and tried to boot it. Doesnt work, so i thought maybe i need to install windows 7 yet again, but the mouse/keyboard wont move an inch in the install setup. I waited 1-2 hours to see if the PC had to prepare for new keyboard/mouse, but nothing happened. Is that because Windows 7 is already installed? How can i get it to boot into the current HDD? I tried setting boot priorities different, but not working either. What to do, please help.
