Windows live one care not updating

There are many possible causes to a GRUB break: Windows writing on the MBR, DRM preventing GRUB from installing correctly, installer bug, hardware change...Updating GRUB as proposed initially by Scott is generally not sufficient, reinstalling GRUB as proposed by Marco is more efficient, but still there are various situations requiring other tweaks (adding options to kernel, unhiding GRUB menu, changing GRUB options, choosing the right host architecture...).Other difficulties for repairing GRUB is the use of chroot, and the choice of the right partitions /disks.

Just boot a Ubuntu live CD, install Boot-Repair and run it. It's a few more key strokes, but hey, it works. If users are booting one OS much more than an assortment of others, this can be faster (and safer) over the long run.

When GRUB is broken, the user generally does not have access to systems, so repair must be performed from a live-session (live-CD or live-USB).

Backup partition table to text file & save to external device.

sudo sfdisk -d /dev/sda Thank you for your interest in this question.

The Windows installer doesn't care about other OS in the system. Also dual booting did work with windows 7 so doesn't it contradict your first line that "The windows installer doesn't care about other OS in the system." I never got in trouble by using these instructions: https://wiki.ubuntu.com/Grub2#Recover First of all, you must start your system from a live cd.

Then "METHOD 3 - CHROOT This method of installation uses the chroot command to gain access to the broken system's files.I then did a clean reinstall of Windows 10 which was successful but the tablet no longer recognizes the bluetooth keyboard and mouse.The control panel shows bluetooth is enabled and scanning for devices.Once the chroot command is issued, the Live CD treats the broken system's / as its own.Commands run in a chroot environment will affect the broken systems filesystems and not those of the Live CD.I've tried turning bluetooth off and on again, power-cycling the tablet, power-cycling the mouse but no go.
