Windows 10 and Ubuntu Dual Boot

Hi All,
I have 2 Hard Disk, 2 TB and 1TB. I have Win 10 on the bigger 2 TB disk and had Win 7 on the Second Disk as a second boot. but as of late since I have upgraded, yesterday whole day my machine gave me many problems... I had to Rebuild BCD many times and now its stable...

The second Disk was not showing at all... I thought maybe its problem as it has win 7. Now I have removed the Win 7 and have only Win 10 on the 2TB disk.

I wanted to install Ubuntu on the 1TB disk (I want it as a fail safe if my win10 gives some problem - I can at-least boot in Ubuntu and access the net to search for a solution)

Can someone help me in this and also if will I have the dual boot option screen where I can choose to boot with win or Ubuntu.
Thanks,
Prasadh

Hi Rindi,
Thanks for the useful Info you gave.
But I want to install it on the 1TB disk which has 2 partitions of 240GB and 691GB. About Ubuntu not that good... well I just downloaded a1.7 GB installer and wrote it on a DVD :(

can I directly double click the installer and install it on my Drive H:  

OR

I have to restart the machine with the disk in cd-drive and it will boot like the win installer disk.

thanks,
Prasadh
some additions:

The Drive H: is the 240 GB part of the disk...  so now Win 10 will be on Drive C: and Ubuntu on H: (both on separate hard disks) will I be able to have Dual boot?

got it...  think I should dive in and install it... will give the feedback after some time.
Hi Rindi,
I tried out installing Ubuntu... here is feedback:

When machine booted I got 2 options 1) Check Trial 2) Install Ubuntu - I selected Install Option.

I went till the select Drive to install stage (The drives were named as "sda1", "sdb2" etc as you said)
But when I selected the appropriate drive and clicked install I received a popup window with a message:
"No root file system is defined"
"Please correct this from the partitioning menu" - the selected drive is ntfs

I did not know what partitioning menu is and I quit at that stage. but a good thing is that after I said Quit, A Trial Working version of Ubuntu opened and I was able to open Firefox and Browse.

so The good thing in this is that I feel I can use this DVD whenever I have problem with windows and boot thru DVD and use firefox to search for solutions.

I was not able to check my other drives or see content on them as a long warning message showed when I clicked on say drive "sdb2" it said could not mount something something... use option "ro"...

the message was quiet long and I did not write it down.

will I be able to see contents of all drives when I load Ubuntu in a trial mode?

thanks,
Prasadh
yes and when I exit Ubuntu and remove DVD... I can properly boot to Windows and my win 10 stars correctly without any problem.

Yes my problem has been solved as of now with Live mode... I can access internet in case of emergency. So I am not installing Ubuntu as of now ... maybe later when I want to learn more about it.

Thanks for your inputs.
