dual boot multiple hard drives

August 4th, 2016

im trying to dual boot with multiple hard drives. one osx and one windows. what im trying to achieve is something like when u dual boot with one hard drive and u get ur os options and u got a counter before it defaults to the os. is this possible?
Answer #1
Negative…you’ll have to pick which drive you want to boot with every time you turn your computer on.
Answer #2
Well my Ideneb auto loads if i don’t press a key on the keyboard to choose which OS if thats what you want.
Answer #3
Simple solution if you don’t want to put all the OS in trouble:
If you have multiple HDDs , (and you want each HDD to be bootable) then follow this (it will take some time)
Remember, After each step you have to Plug OFF your computer
1) Disconnect all the HDDs.
2) Plug the HDD (plug only one HDD at a time) and install the OS and finish the installation.
3) Unplug that HDD and Repeat step 2.
4) Repeat step 2 and 3 if you have more HDDs.
After finishing all the things, follow this:
1) Plug all the HDDs now.
2) Enter the CMOS (or BIOS, whatever you call) and select the Boot Sequence.
Remember:
For this thing, you must always remember which HDD contains which OS, otherwise you will boot to wrong OS

That’s the same thing I do, only thing is that I only disable the HD in the BIOS instead of detaching it. It’s also a great way to prevent that you erase a hd which contained files you didn’t want to lose.

^ this is what im trying not to do. pressing f12 each time and selecting the HD. if u dual boot with a system there is an option box that pops up Automatically right after bios loads and u can select which OS to boot from. im trying to do the same thing only with 2 or more HD
