I had both Ubuntu and Windows installed in dual-boot config. Windows 10 was on my SSD and Ubuntu 14.04 on the HDD. One day, the HDD crashed and Ubuntu was gone, not a big deal because I got a new HDD. But in the UEFI of my Asus z-97 motherboard, signs of Ubuntu were still there. Like in the boot menu I could still choose Ubuntu, but that did not make anything because the HDD was gone.
I wanted to remove all rests of Ubuntu and tried to use EasyBCD. I used the repair boot file option in the BCD management option. After that I tried to reboot and, surprise, I can't do anything. It just sticks with the Asus logo with the text "press f2 or del to enter bios" which I obviously tried without working. I cannot enter the UEFI firmware, and it does not boot on the only OS on my computer (Windows 10).
What should I do?
