Dual Booting Windows 10 and Ubuntu 15.04

Hi,

I've just built my desktop and I'm trying to dual boot Windows 10 and Ubuntu 15.04.

I've already partitioned my hard drive, and installed Windows 10 and Ubuntu 15.04, but I'm trying to get to a place where I can choose what OS to start whenever I turn on my computer.

At the moment, I can run both Windows 10 and Ubuntu 15.04 if I go into the BIOS and rearrange my boot priorities, but that's just a huge hassle. Is there a convenient way to choose at startup, similar to how Windows 8 had this?



Thanks

I don't realy understand what you have done.
As you said you have create a new partition in order to install ubuntu (you probably have create a swap partition too).
Those actions are telling me you have installed both Operating Systems on the same hard disk.So if you are setting boot priority from bios it means you have install each one on separated hard disks with separated bootloaders or you simply have install only linux bootloader on an other disk.
In any case you can setup grub to boot every OS you have installed on any hard disk.

My BIOS can rearrange partitions for booting order. Also, I can't seem to get to grub, it either boots straight into ubuntu or straight into windows depending on which booting priority I put the BIOS into.

So you're saying not only can you specify which disk you boot off but also any partition off the chosen disk, I'm getting on a bit and it's news to me.
How many physical disks are installed?

Doesn't matter. When in Windows 10 you can use bcdedit to create a new boot entry to point to Ubuntu. Of course this is difficult as it involves using the command prompt. Fortunately you can do that easier using a utility such as EasyBCD.

Only one physical disk is installed at the moment.

So all you need is add a boot entry for Ubuntu in Windows Boot Loader with EasyBCD.

It sounds like he's Windows in UEFI mode and Ubuntu in Legacy(MBR) mode and he's switching between UEFI/Legacy (MBR) hence no Grub.

I'm not sure whether the Windows (UEFI) boot loader will switch to legacy mode. I'm not au fait with UEFI systems. Too old and stuck in MBR

In either case, he will have dual boot by adding a boot entry for Ubuntu in Windows Boot Loader.

He could also make grub his first bootloader and set it to chainload windows bootmanager.But if he had use wubi for virtual installation the only solution would be to setup windows bootmanager.
