I lost Win 10 in the boot menu on an X220 Thnk Pad

I installed Tumbleweed on an X220 Think Pad with Win 10. I first set the bios to boot legacy and secure so that it would boot either Windows or OpenSuse. It worked great for about a week and then after the updates, the daily updates, last Saturday I no longer see Win 10 as a boot option when I start the computer. The partitions are still there but somehow I no longer can see Win 10 as a boot choice and have not been able to access the windows hard drive area. ?? Any thoughts on this? Suggestions? Any help would be much appreciated.



Make sure Probe Foreign OS is checked.

Then re-install the bootloader (Grub).

Also be sure that fast boot is off in Windows or grub may not see it. But if this is a legacy boot I’m not sure if fast boot functions in a MBR boot.

Hi all,

I did updates again last evening and now Win 10 is back… Boots fine, works OK, as it should. I was quite surprised.


This is getting weird. It (Win 10) now is missing again. ??

Assume the question marks are harsh language…


How do you shutdown Win10?? Any hibernation including fast boot will make the partition invisible to Linux

Show us fdisk - l

Hi all,

I shut off fast boot and it has been OK since then. I never use suspend for any software. Thanks for the idea about killing fast boot.
