I have installed Ubuntu from a usb to my Windows 10 drive and partitioned it for Ubuntu to dual-boot. After installing it, I rebooted and the grub menu to choose between Windows and Ubuntu appeared the first time. After choosing windows, I tried to reboot it and it's stuck on the restarting screen. Is it because I installed it on the same drive? Something about ext4 and Windows clashing?
How do I start repairing it? From Windows or Ubuntu? and how?
