I have a Lenovo e570 laptop. I can't find Windows in the GRUB boot menu after installing Ubuntu, and I am interested in booting Windows 10 again.
I had the usual problem of not seeing Windows 10 in the boot option after installing Ubuntu. I tried
sudo update-grub and boot repair (with different options), but it didn't work.
Here's the Boot Repair Boot Info Script.
This is a screenshot from the GParted screen showing unexpectedly that a boot flag is on the FREE_DOS partition. Is there a problem with the flags?
I also tried using a Windows USB stick to fix the startup issues, but it didn't work.
The partition with Windows 10 exists and is mountable with everything in it.
I ran Boot Repair again and this was the result. Also the Repair Windows boot files option is still grayed out.
Is there any specific option for Boot Repair when it is the efi/legacy problem? I tried the separate efi partition option.
Also, what should the BIOS options be for UEFI/Legacy booting?
