I currently dual boot my laptop with Windows 8.1 and Ubuntu 15.04.

Now I want to give Windows 10 a try, considering the positive reviews it has been garnering. But I don't want to mess my existing installation.

Has somebody tried the same or can guide me about the consequences?

    **First backup all data/settings.** *In general Windows does not recognise other OS', so will NOT give specific (or clear) guidance to stop you doing anything stupid.* That said, it should allow you to just 'upgrade' the existing OS (using the same partition). – david6 Jul 30 '15 at 11:26

    @david6 , So will it leave my Ubuntu boot partition intact? – enitihas Jul 30 '15 at 12:02

Upgrading may mess with your grub so be prepared to do a boot repair. Otherwise it wont mess with your pre-existing partitions as windows doesn't even recognize the ext4 format.
