I'm trying to determine if I have sufficient drive storage resources for Windows 7 to run in Virtualbox. I am running Ubuntu 18.04 in a 50GB ext4 partition on a 1GB Hard drive (Partition 5 below).
Partition 1 is ntfs from ex-Windows 7. Since it is 75% full of needed data, resizing that partition is not possible.
There is also a 50GB Extended Partition. AFAIK it is unused.
The Ubuntu partition (Partition 5) has about 25GB free space. Is this enough disk space? And if not, is it possible for the virtual Windows 7 to run in another partition, or in part of another partition?
As a strictly side question, Ubuntu software has Virtualbox version 5.2.34, while the Virtualbox website has version 6.1.6. Which one would be safest/necessary for my purpose, and not having used this application before?
