Ubuntu is very easy to install. There are two options how to install it. The first is downloading a copy of the latest Ubuntu Release and burn it on a DVD. But if you have a newer computer you can boot from USB. If your computer doesn’t automatically do so, you might need to press the F12 key after restarting to bring up the boot menu, but be careful not to hold it down – that can cause an error message.
Sometimes happens that our Linux OS can’t be open or booted! and so? we can’t loose our data. DiskInternals Linux Recovery is a handy no-cost utility that runs under any version of Windows and designed to recover the erased or damaged information that is kept on Ext2/Ext3 partitions. DiskInternals Linux Recovery might come in handy on a number of occasions when due to the unforeseen contingencies there was a loss of important data stored on Ext2/Ext3 disks.
