Windows 10 & Xubuntu

[Jean Richard]

On an old laptop Asus X71SL with only one hdd I installed Windows 10 pro then grub2win. No problem so far.
In a second step I installed Xubuntu alongside Windows 10
When I restart the computer I go directly to Xubuntu
What's wrong with my installation ?

Hi Jean,

Please run the Grub2Win diagnostics by clicking the blue "Diagnostics" button near the bottom of the main Grub2Win screen. Then send me the diagnostics file.

I need the diagnostics to understand your specific hardware and Grub2Win configuration.

Thanks,

Dave

I think running Grub2Win diagnostics requires booting Windows, which sometimes requires pushing a F8 or F10 or F12 key when booting to set the booting sequence.

Hi again Jean,

After researching your laptop specs, it appears that this motherboard contains BIOS, not EFI firmware. If that is the case, I suspect that the Xubuntu install overlaid the MBR on your boot disk.
This is a very old motherboard, circa 2009, so I cannot be sure of the firmware.

You may have to boot from your Windows 10 Pro install media and run the system repair to restore the proper MBR.

Pleas let me know of your progress.

Thanks,

Dave
