Hyper-V Linux I/O error, dev fd0, sector 0
This is caused by Hyper-V’s virtual floppy drive. There is no storage media attached to this drive, and for some reason the OS does not like that.
To fix this, we can remove the floppy module. This must be done with administrative privileges.
Enter the following commands:
echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf sudo rmmod floppy sudo dpkg-reconfigure initramfs-tools
