I used to have Windows 10 and Ubuntu installed in my laptop then I decided to remove ubuntu. After removing ubuntu from the boot menu using bcdedit command, my laptop won't boot up after restating and I can't even go to my bios. I'm stucked at Acer logo press f2 to enter setup. I followed all possible solutions I found here in the community but no luck. Can someone help me on how to flash my bios using a usb? Thanks in advance!
