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...)

  • How would I restore it if Windows messes up the MBR? Will restoring it mess up the Windows partition?

  • To restore just run dd if=~/MBR.backup of=/dev/sdX bs=512 count=1. Regarding Windows partition, It won't mess it (if you haven't modified it since you dded your MBR, but I don't know if it will work "out of the box". Anyway, you have a gide in the next link to install windows 10 with linux makeuseof.com/tag/try-windows-10-youre-running-linux
