Need help removing rEFInd entries

[Kyle]

Basically, i have 4 internal drives in my MacPro 1,1

• 240g SSD loaded with OS X El Capitan as HFS+ (case-sensitive)
• 120g HD loaded with Windows 10 64-bit as NTFS
• 80g HD loaded with Elementary OS Freya (Ubuntu 64-bit) as Ext4
• 1tb HD used for storage formatted as NTFS

Currently, i am triple booting all three operating systems, however my rEFInd setup looks like this

I'd like to remove the duplicate entries, however, i am clueless as to how to set it up. I also do not know which efi/bootloader file im supposed to be looking for when setting up the "do_not_scan_dirs" section of the config.

The only reason im here asking for help, instead of endlessly browsing rodsbooks is because i have an older mac with a 32-bit efi. In order for me to get 64-bit variants of Ubuntu & Windows, i had to use BIOS install rather than EFI,

so basically, im not sure which directory/file im looking to point the config file to scan for.

To give you some information that may help, here is my output of diskutil list

The images circled are the only OSes i'd like to show up in my menu

I can't help without more information -- namely, the descriptions that appear when you highlight each of the OS icons. This topic is covered in the rEFInd documentation:

Roderick, please see here; i have detailed every aspect of my issue.

Thank you in advanced

UPDATE, adding the 32bit driver for ntfs allowed me to hide my partitions because they could now be identified. Except for the ones labeled Whole Disk Volume.

I tried adding dont_scan_volumes "St0r4g3", "whole disk volume"
to my surprise it actually worked, it hid all entries which were labeled as whole disk volumes...
unfortunately, i can't get refind to recognize my ext4 partition for linux which is Freya HD, so this also hides my ubuntu entry..

can i make a manual stanza to boot grub via BIOS with rEFInd?

[Kyle]

so, somehow, Windoes got corrupted, im guessing because of a techincal preview build update error

i find it interesting however, i just completely formatted the disk as NTFS (now labeled Microsoft HD).. and even with a blank NTFS disk rEFInd still sees it as a bootable option for windows as "whole disk volume".. not even detecting the label... tried the same using FAT with no success..

Even GRUB when booting linux gives an option "Windows 10 recover on sdc1" (which is irelevant really, since my keyboard has almost no affect when entering BIOS emulation and i cannot do anything but let the countdown boot Ubuntu)

i also went into gParted and removed the "boot" flag from my St0r4g3 and this drive, which still did not hide the entry for this volume..keep in mind its just data, no OS installed

what gives? Does rEFInd simply detect all NTFS and FAT drives as boot options even with no OS?

Sorry for literally bombarding you with questions, im just very very confused.

SOLUTION.
Converting all MBR disks into GPT disks seem to eliminate all issues.
I now dont have anymore duplicate entries.
