HOW MUCH HARD DISK SPACE UBUNTU INSTALLATION TAKES
Ubuntu requires a minimum of 6 GB of space for installation. As you are saying you have 20 GB available, it is more than enough and Ubuntu can be easily installed!
CAN I INSTALL IT IN DRIVE D'S REMAINING SPACE
Well, you cant just install it on Drive D. You have to first shrink the partition. To do it, follow the steps:
- Go to Charms and hit Search. Now enter Create and Format Hard Disk Partitions. Click on the first link in the search.
- You now have to provide administrative access. When done, in the new Window that launches right click your desired partition (in this case D) and click Shrink.
- In the new window, after Disk Engagement queries the drive for available space, enter the amount you want to shrink. Make sure you have that much free space available prior to shrinking.
- When entered, click shrink.
Now that you have successfully shrunk the space and created a separate partition for Ubuntu you can now install Ubuntu on it, without losing you data or creating a backup of it on another hard drive.
