  • If you could, it is much easier to install windows 10 first then add Ubuntu to it as the Ubuntu installation is much more transparent and allow you to specifically install it into a partition. UEFI installation works best as Ubuntu simply add an entry to your efi partion alongside windows. Windows should show up in Ubuntu and you can switch between grub and windows boot manager using efibootmgr in Ubuntu. – Bernard Wei Apr 11 '19 at 18:34

Grub is less scary then it sounds, in fact it is incredibly friendly.

Ubuntu having been in this dynamic of dual-booting with windows from the start, has become very experienced with dual booting problematics.

Grub is the bootloader for most linux distributions.

it is faster, more configurable, ect ect ect...

trust it.

as per : Install Windows or Ubuntu first after clean wipe?

you should install windows first (as a complete format of the disk) and then install ubuntu. the other order is too hard for you to do.

  • isn't this pic up there is during install ? i dont want to install ubuntu, i want to install win 10 :( – mohamed ehab Apr 11 '19 at 14:58
  • oh you changed your post. I was also misslead because you listed out you /root and /home sizes... Honestly I don't recommend doing it that way around. if you can back up your files first. The best approach to dual booting is wiping the drive durring the win10 install and then installing ubuntu afterwards. https://www.google.com/search?q=should+I+install+windows+or+ubuntu+first%3F&oq=should+I+install+windows+or+ubuntu+first%3F&aqs=chrome..69i57j0l2.14191j0j7&sourceid=chrome&ie=UTF-8 – tatsu Apr 11 '19 at 15:04

  • it's really really so much easier to do the opposite, but if you really really feel up to it.. – tatsu Apr 11 '19 at 15:08
  • hey one last question, can i just plug in my usb drive and start Win 10 installation and edit my 350 GB partition to allocate a 40 GB for Win 10 C Drive and call it a day ? yes or no :D – mohamed ehab Apr 11 '19 at 15:21
