I successfully dual booted Ubuntu 17.10 (latest stable) and Windows 10 (latest version) - buy that man a drink, I hear you say, because that was far from easy!

I could always boot up Ubuntu as long as I didn't EVER try to re-boot Windows. If I ran Windows then the system became corrupt and eventually I had to back-up my Windows 10 to external hard disk (I never ever want to do this again)! Then re-install everything and start again to make my PC dual boot - this is where I am now. Scared to boot into Windows in case the disk is corrupted. I can happily repeatedly re-boot into Ubuntu though via Grub2 and my Windows 10 is installed alongside.BUT if I let Windows boot by default i.e. system restart but don't activate Grub2 just let default boot up occur - that always starts Windows 10 even if I don't want it to!

So, any ideas on how to prevent the disk corruption so that I can happily dual boot either system AND safely choose the system and the default boot system?

I could supply more and more detail but until I have some means of progressing the problem I will hold my tongue. I don't know as yet what information is relevant to getting at the problem.

Thanks in advance etc... Dave

    1) did you shrink the windows partition from within windows? 2) Is hibernate and Fast Start disabled in windows? – ravery Dec 6 '17 at 1:12
  • In addition to ravery's comment this question is also worth considering: Windows 8 deletes GRUB when booting – karel Dec 6 '17 at 2:22
