If you want to dual-boot your favorite Linux distribution and Windows 10 Technical Preview on any computer, whether the computer has UEFI firmware or not, the Windows 10 Technical Preview installer is only capable of creating partitions using an MBR partitioning scheme. And so you should be aware of that when creating partitions for installing any Linux distribution. Note that this might not necessarily be the case when the final edition of Windows 10 is released. But just something you have to keep in mind before then. If you want to test-drive Windows 10 Technical Preview, ISO images are available for download here.
So when I created partitions to use for installing Ubuntu 14.10 alongside Windows 10 Technical Preview on the same hard drive, one of the Ubuntu 14.10 partitions had to be a (extended) logical partition. And the boot loader had to be installed in the Master Boot Record (MBR) of the target hard drive. Regards, Shekhar Dohtre Unix & Storage Engineer . 973-200-6150.

I tried with all genuine methods and installed debian 8.1. But whoa! I lost my activated version of Windows 10. I WAS able to access all my hard drives as I did a proper shutdown but the grub os list showed no link to windows. I reinstalled windows 10 and still am eager to run linux flawlessly. Please guide me.

Well make sure you have unused space on the disk before installing (that is, not part of a partition, not free space on C:). As long as you don't touch the windows partitions while installing, windows should survive just fine. Of course backups are always recommended before doing anything major, like an OS install. -- Len Sorensen -- Himanshu Shekhar IIIT-Allahabad IWM2015001
