1 TB HDD
This is what the partitions looked like from the OEM with 8.1 installed:
2.27 GB NTFS
Healthy (System, Active, Primary Partition)
914.59 GB NTFS
Healthy (Boot, Page File, Crash Dump, Primary Partition)
Healthy (Recovery Partition)
System = .25 GB in use - 2.02 GB / 89% Free
Windows (C:) = 34.74 GB in use - 879.85 GB / 96% Free
notnamed = 0 GB in use / 100% Free
After Custom upgrading/installing to 10, the partitions remained exactly the same. Info says they're MBR partitions.
I intend to dual-boot with LM17.3C64-bit, but before I install it, I'd really like to understand these present partitions first so I can resize (C:) and fully understand what the other two do, and if they're truly needed. Worst case scenario ( I think) is that I leave all 3 in place and just shrink (C:). However, does that only leave me with an Extended partition to install LM to, since I understand MBR only allows 4 primary partitions total? The MB has the option to use UEFI, and I believe I have read somewhere that if that's the case, MBR automatically goes to GPT if more than 4 primarys are created.
Ideally, I'd like to have only 1 (or 2) Windows partitions, and 1 or 2 LM partitions, or whatever the most sensible/efficient setup is. Total HDD is not an issue since I doubt I'll ever, ever use 150-200 GB for anything but OS-needed stuff. I also intend for LM to be used primarily.
Any/all input is greatly appreciated. Thank you.
