I have no access to Win 10

[Leplusbeau]

Hi, I have different Linux distributions beside the Win 10. After the major update of Win late December the grub was broken. I tried to re-install the other Linux distribution to bring back the grub. Now, there is no Win on the grub either with F9. I can see and enter the partitions of Win by the Linux systems. But I can't lunch the Win. Is there any solution without formatting?

Hi,

take a look in BIOS/UEFI and check the boot order entries, you might have more than one Linux entry, try selecting another one if you have more than one!.

Hi,

In BIOS/UEFI no os boot manager found.

Thank you,

In the F9 pic, did you select "Notebook Hard Drive"?.

Hi,

Yes. After that it returns to the grub where listed only the Linux distros.

Thank you,

Hi,

if you have Debian based Linux systems, try "Grub Customizer" and see if that can repair GRUB for you!. You may have to re-install GRUB on one Linux system first and then try it!.

There is also Boot Repair which is an excellent tool to repair GRUB!.
