Hey everyone. So I was playing around with some linux distros installed on the same disk (I know, I know, not ideal, but I only have on SSD on my laptop) and now Windows update fails, and I think it's because of the changes the linux installations made to the bootloader, since major Windows...

Hello. I use a Lenovo laptop where I had W10 and Ubuntu on different partitions. It would let me choose between W10 and Linux upon startup and would boot into Linux by default. After a long update last night, my PC boots directly into Windows (no more bootloader screen). I still see the 60GB...

Below in my screenshot I have marked the W10 installation, W10 bootloader, and Linux install. For some reason, every time I install W10 it decides to install the bootloader on a seperate drive. When I boot into the linux drive grub shows W10 but I am unable to boot into it. I am able to boot...
