I am planning to install Ubuntu along with Win7 on my system. I have 2 different drives C: and E:. E: drive is created after shrinking the Windows C: partition. Can I use my E drive for installing Ubuntu? Also is there any guide to step by step installation of ubuntu along with windows.
Good that you trying out Ubuntu,
Delete E: and make a unpartitioned space through windows 7 disk management.
When you start Ubuntu installation select the free space.
Please mention the version also
I guess u have one big E drive. Such big drive is not needed. Shrink that big partition and make some space for Ubuntu, may be 20~30GB is very adequate.
I think u know this already. Here's how u shrink your drive.
Once U have 30GB u can go ahead with Ubuntu installation in this way.
During Installation Select Specify Partitions Manually. To begin creating partitions, select the free space and click on the Add… button.
Click “Install Now” to proceed with the installation process.
There's also another wonderful Propitiatory Software for windows with which u can literally control Ur NTFS/FAT Partitions. Its called EASEUS Partition Master v5.5 Pro, U can use this to partition any Drive without loosing ur data.
The concept of drive-letters is a windows thing. In fact you only need free space to install ubuntu. I guess 10 gb are enough to give it an ambitioned try, but more space can't hurt.
The Ubuntu installation fully supports an installation alongside with windows (you just have to click the option in the installer and adjust the partition sizes with a slider). As an alternative you can create another empty drive or free disc space with a windows partitioning software and install Ubuntu instead of the free disc space or the drive.
Both ways are not very complicated - and in the end it won't matter which way you choose.
When start the computer, the first thing you see is a selection menu (called grub) where you you can choose what OS to start.
Good luck installing Ubuntu.
