I installed ubuntu in dual-boot in a laptop with pre-installed Windows 8.1 (uefi) with 500gb HDD and 32gb SSD. During and after installation everything went Ok, but as recommended, I leaved the SSD alone and only used the HDD. Now after the installation (couple of months after) I wanna make use of my SSD and I wanna know if I can change it's partitions without concerning and if
bcache has any use in this case. Taking in consideration that I wanna make the best use of it for Ubuntu not Windows.
Note: It was highly recommended that UEFI or SecureBoot Mode was disabled to install Ubuntu in dual-boot, since I didn't figured out how to disable it (there wasn't any option in BIOS) I leaved the fast-boot off and SecureBoot unchanged (therefore ON). As said everything went OK so I leaved that aside, occasionally when I'm booting Windows it goes to a repair screen then turn off the laptop, I start it again and everything goes fine. I am just saying it because I don't know if it influence in anything.
Screenshots of my actual partitions
(C: ) and (D: ) are both for Windows, the others I have no idea.
I didn't know a proper way to make the partitions then set it to do automatically during the installation. Therefore all other partitions are strange to me (Recovery, Restore, etc...).
