This is what the partitions looked like from the OEM with 8.1 installed:



2.27 GB NTFS

Healthy (System, Active, Primary Partition)


Windows (C:)

914.59 GB NTFS

Healthy (Boot, Page File, Crash Dump, Primary Partition)



14.65 GB

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.

Shrink the C drive.

As for Linux its possible to have it use logical partitions, you may not need it as really even with MBR its possible to have more than 4 partitions.

Or just reinstall windows 10 and have it set to GPT, it will solve the partition limit.

Its your call but again its a good thing linux can install in a logical/ extended partition

Like MadmanRB said, just shrink your C and leave the space unallocated. Do this from within your W10.
LM will detect the unallocated space and will offer to install alongside your existing W10. Choose that option and let LM set the GRUB (boot loader) where it suggests.

My own situation: Dual boot with W7 on MBR, 5 partitions and Linux booting from an Extended (Logical) Partition. 
Remark: I don't have the "System Reserved" partition that Windows normally has...  :devil:

Please backup important files before you begin... 
Any problems, post back in the Linux & Unix section. Good luck!  :wink:
