Hi, First off it may not be necessary to disable UEFI:
viewtopic.php?f=4&t=9754#p48489I have had Windows 10 and MakuluLinux 10 living side by side but not on an UEFI BIOS rig. The crunch with 10 is that it has a System partition at the beginning of the drive of 350 Mb (like the 100 Mb System partition in 7) but also has one at the end (450 Mb Recovery). Now as you have a 'branded' PC you may also have a 'hidden restore' partition - so this means a total of four partitions and they will all be marked as Primary in the 'mbr' or GPT table of the drive which means no place for '/' to reside.
How I fixed my issue on a none EFI BIOS rig was:
1. Right-click computer in Windows 10 and select 'Manage' then go to 'Disk Management' - yoiu may want to run Chkdsk (which will require a reboot - this may well not be present in Win 10) but at the very least, defrag 'C:\' before letting Windows shrink the partition for you.
2. Create an 'extended partition' in the space left after shrinking.
3. create the following partitions inside the extended partition:
A. '/boot' - 512 Mb formatted to 'ext4'
B '/' formatted to 30720 Mb (30 Gig) formatted to 'ext4'
C a logical partition with 4 Gb 'swap area' at END of partition.
D whatever is left between '/' and 'swap area' format to 'ext4' and mark as '/home'
4. Make a note of where '/' is (its sda number) and be sure to put GRUB in '/boot'
5. Install NeoSmart EasyBCD bootloader in Windows - this allows you to fine tune the 'mbr' so as not to affect booting to windows.
Other things to take care of are ensuring that you go to the unseen part of 'power options' - particularly the bit about the hard drive going into sleep mode - this means the drive is never turned off and you will never be able to boot any linux DVD!
