Too many random boot options available in bios boot options for Gigabyte z170x-UD5 after installation of Elcapitan 10.11.1

[hashish.k]

I am dual booting windows and OSX Elcapitan 10.11.1 on my build with following

a) i5-6600

b ) gigabyte z170x-UD5, with modified f4 bios to disable the  IOAPIC

c) internal graphics HD530

d) 8gb Crucial ddr4 2133 mhz

e) windows (micron 1J1) and OSX (OCZ ARC 100) on 2 separate SSDs

 

Every time I reboot my computer whether windows or OSX there is a new boot option added to my BiOS. When there are too many boot options on the BiOS when I press F12 to boot from my USB it just resets and restarts the computer. I go into the bios and try to change the boot order to boot from USB, I am not allowed to do it.

what I tried:

a) I disabled the sata port connected to the OSX SSD. Then restarted the computer but my motherboard BIOS does not see the SSD and I cannot reenable the SSD without having to clear the CMOS.

b ) The only way to reset this  was to remove the OSX boot SSD and boot to BIOS and then shut the computer and reconnect the OSX SSD back.

 

I could not find a solution to this online and am thinking this is related to clover bootloader. While not a terrible inconvenience, any help in solving this will be greatly appreciated. Screen shots of the bios are attached.

I had this problem too, it's a strange one...

 

Not sure what fixed it, they just magically all disappeared one day and dindn't come back.

On another note -- I'm assuming you have graphics acceleration with the HD530 and, if so, did you have to do anything in particular to get it functioning?  Thanks.

No i don't think i have graphics acceleration. This is my first build. I get some garbling of graphics when I use safari and when playing youtube at the top and the bottom. Contemplating getting a cheap NVDIA card to resolve this issue.

Bummer, thanks for the info.

I am getting the same thing on my UD5-TH board as well on my SM951.  There is an F3 firmware for that board that I am not sure if my machine has yet that I will try tomorrow and see.

I am on F4 and still doing the same thing.

solved. This has already been discussed on the following thread. I found out about this thread from the other hackinstosh forum,where the guide is in a little more detailed format. Apparently too many boot options will eventually cause problems while booting

Thanks to trioset for figuring this out.

 

edit: alternatively use the easyuefi within the windows and delete all unnecessary options.
