All has been fine for a month or so since I installed Win10 and Ubuntu 16.04.3 LTS side by side (from scratch). Bios is running UEFI boot mode. Now suddenly when selecting Windows from grub, windows starts in startup repair wich seems to be infinite loop (repair is unsuccesfull according to windows. Selecting Ubuntu from grub menu starts it and it works fine.
Have tried updating grub, have tried running boot repair, no joy :( Also if I change the boot order and try direct boot from windows bootmanger, same infinite repairloop occurs.
Here's the pastebin from boot-repair-tool ----> http://paste.ubuntu.com/p/2SZ2VNWF39/
Any help appreciated
