Another day another question. :)
I've been trying eOS for the last couple of days on a external hdd. I very much like what I see. Because of that, I want to move from ubuntu to eOS. For that, I was checking the partitioning of my 2 harddrives. I found strange things and I am curious which I can remove. In the picture you find the output of lsblk:
sda is my classic 1Tb hdd. It contains a data partition which is shared by windows and linux. At also has the home parition of ubuntu. That one will be removed for eOS as I will be working with softlinks to the data partition. It also contains a curious BIOS_RVY partition. After some searching it seams to be a partition containing the factory defaults of msi. Can i delete it if I make a image as backup? I don't feel like losing 20Gb to some factory defaults. It also contains a 4th partition wich I can't seem to mount. When trying I get something that basically says "we have no idea what went wrong. Maybe you get some hints in the syslog." that however doesn't seem to contain anything useful.
Next drive, sdb, is my ssd. First partition is named WinRE tools. I have no clue about what it is or contains. Anybody got some hints? sdb2 is a /boot/efi parition so that one stays. Next up is some kind of mysterious microsoft reserved partition. That one should contain boot files etc for windows. So I believe that has to stay. As does the next, which contains my wind
