I replaced my Windows OS with Ubuntu. After a successful installation I can not find my other drives ( i.e. D, E, F, G ) and their contents in Ubuntu. Is it erased? I was not aware of that. Is there any way to get the contents back?
P.S. At the time of installation I clicked the "erase and replace windows", not "something else".
If you only had one physical drive in the machine that would indicate that when Windows was installed that drive was partitioned into C, D, E, F, and G.
When you installed Ubuntu it saw that single physical drive and treated it as a single physical drive. The "Erase and Replace Windows" then was acting on that drive.
Running dh -h will allow you to verify if all of the space on the drive was reused by the installation. Compare the output to the size of the physical drive.
'erase and replace windows' .. erases Windows and replace it with Ubuntu. So, Yes your Windows installation has been overwritten.
