HI Guys; i installed win 10 first and then i installed Ubuntu in LVM, It boots strait to Ubuntu, how do i set it to boot either Ubuntu or Win 10,
Normaly in other Machines i installed for exemple Win XP and Linux mint and it offers to install along side Win OPS then i update grub and that's it,
here it offers me LVM or others, thanks

that would be the win 10 developers alpha preview

turn MS's "Secure Boot" back on
then it should boot into win

Thanks john;My lenovo Thinkcenter 71e I5 2400 doesn't have nothing in the bios set up "secure boot"?

Have you read laptop specifications. Does it say uses UEFI Firmware. Which year it was released?

Can i install win7 in this Lenovo and then install Ubuntu14.04 along side and then upgrade Grub same way i do with win XP and ubuntu,and then update win 7 to Win 10 TP?

i have Win XP and Xubuntu 14.04 on my Dell P4 i used the mode in the partition ''along side"
but when i try to install Ubuntu along side win 10 tP, the Along side option in the auto Partition doesn't show, i have auto partition, erase win 10,KVL, Others which is make partition manually.

If you used the LVM option, it may have overwritten your windows install. I'm seen posts in that regard at the Ubuntu forums but have never used LVM myself.

If you install windows 7 and then install Ubuntu, you may not see the "Alongside" option, not sure why that happens, but you would do best by using the Manual "Something Else" option so you know what is happening and can see and select the partitions or unallocated space to use. If you then upgrade to windows 10, you will need to reinstall Grub.

I don't know if this will help. Try reinstalling grub after you boot up to Ubuntu

then run If you still can't boot to windows 10.
You may need to install gksu change the GRUB_TIMEOUT value to a higher amount. Windows 10 is listed as windows recovery on some grub menus.
