I am new to the Linux world and have been trying to install Ubuntu on my Lenovo PC for the past day, but have not been able to install it successfully.
Background: The Lenovo PC came with Win 7, however, I recently upgraded it to Win 10 and now wish to partition it to dual boot to Ubuntu. I have a live USB flash drive with Ubuntu and able to boot into Ubuntu on start-up, but fails to install correctly because of an "unusable space" message.
I had followed a YouTube video and performed the step of segmenting some of the space (20GB) in my C: drive before installing Ubuntu via Windows Disk Management. However, this space has become unusable somehow.
I read on another blog that Windows allows for only 4 partitions on the disk, and apart from C: and E: that I already know of, there are 2 more hidden partitions which Windows creates. I have transferred all my drive E: contents and transferred it to C: with an intention to delete E:, but Windows does not seem to provide an option to delete this drive. I have also downloaded some external tools to achieve this, but even while using them, I do not see an option to delete this particular drive (in my case E:).
I am very confused on which of these partitions to delete (and how) and merge with C: so that I can get some room and flexibility to install Ubuntu?
Am I right in understanding there should be no more than 3 partitions on disk before I install Ubuntu? Link: Lenovo Forums
Which of the partitions in Windows can I safely delete using Disk Management before I proceed to install Ubuntu? (as I still want to preserve Windows as well) Kindly advise. My disk partition currently looks like this (I have merged the 20 GB partition initially created for running Ubuntu):
