Has anyone tried updating to Windows 10 on a dual boot machine? I'm concerned that Windows 10 might mess with the MBR.
Is there a way to preserve the MBR and easily restore it if Windows in fact changes it? The other OS on the dual boot is Lubuntu.
You can save your MBR to a file using dd
dd if=/dev/sdX of=~/MBR.backup bs=512 count=1
Where X is the device you want the backup from. Mind the if parameter it is the device (sda) not the partition (sda1,sda2,sdb1, etc...)
dd if=~/MBR.backup of=/dev/sdX bs=512 count=1
