Ubuntu 14.04 LTS is not booting on dualboot PC running XP.


I installed Ubuntu 12.04 two years ago on a PC running XP (on 500GB volume)and everything waS GOING WELL. The PC has a second HDD 60GB, also running XP. Then I got ambitious and upgraded to 14.04. With 14.04 my problems began. Initially it was working then it took too long to boot up and I would not see GRUB menu at all. I lost patience and decided to go back to 12.04. When I installed 12.04 again, I wasn't careful and so it installed on 60GB volume. There was very little space on 60 GB drive and frequently I used to get warnings about lack of space.
I checked and realised my mistake and decided to reinstall 14.04 on the 500gb volume which has plenty of room to spare. I did this. Now I appear to have at least one install of 14.04 (possibly more), one of 12.04 (possibly more?)in addition to XP in both HDDs.

Initially everything was OK and the black screen after the "Intel" page started appearing with no sign of GRUB menu. After couple of hard restarts , GRUB would appear and booting would proceed normally. Now even that stopped - GRUB does not appear even after quite a wait.
I am able to boot from USB stick.

I want to: 1. Remove numerous Ubuntu installs and revert to 14.04 in my 500gb disc (60gb is too old and could fail owing to its age)
2.Remove Ubuntu from 60GB disc.
3. Install an SSD for the two OSes and use 500GB for data storage.
No1 above is essential, No2 is preferable and No3 is a dream.
I am a newbie and do not have the knowhow or the patience for complicated Ubuntu work. Step by step instructions will be helpful.
Could someone help

That is not complicated.
There are 2 things that you have to determine before removing any linux OS. You have to make sure that Ubuntu 14.04 on the 500GB drive is in control of the Grub menu that you see when you boot. And you have to make sure that the 500GB drive is first in the computer's boot sequence.
Open your BIOS settings and make sure the 500GB drive is listed first.
Then boot into Ubuntu 14.04 on the 500GB drive. Open a terminal.
Re-install Grub to the MBR of the 500GB drive with this command:
Code:
sudo grub-install /dev/sdX
- where X is the 500GB drive - sda? sdb?
On your old system, it could be hda and hdb.
Now you can remove the old 60GB drive from the system anytime you want, or erase the contents. After you do that, you can run
Code:
sudo update-grub
to remove the old linux menu entries from the Grub menu.

removing an ubuntu distro is easy, just boot into any other os (from usb) and simply remove that partition/filesystem. But first save all your important data.
Reverting probably has no any meaning, you need to reinstall 14.04, but first insert your new ssd.
