Multi-Boot & Multi-Harddrive booting

[JoesMorgue]

OK. My computer multi-boots to Windows 7 & 8 right now. 8 is on an SSD.

I am thinking about adding another HDD, moving 8 to the new HDD, and installing Windows 10 [Technical Preview] onto the SSD. If I disconnect the drives with 7 & 8 during the install, then add them to the boot menu after, can I make the computer boot to the HDD with 8, have that boot menu default to 8, with 7 & 10 as options, and if I make the computer boot off the SSD default to 10 with 7 & 8 as options?

Clone or image Windows 8 to a partition you create on the HD, boot into it or Windows 7 to add the other OS to a Dual Boot menu using EasyBCD (click Download - no Name or Email required).

Unplug the 7/8 hard drive, plug in the SSD to Clean Install Windows 10 Technical Preview.

After install plug back in the hard drive, boot it when needed using the one-time BIOS boot menu key, leaving the SSD as drive set first to boot in BIOS setup.

If this is not to your liking, then boot into the hard drive OS from which you set up the Dual Boot with EasyBCD, add Windows 10 to the Dual Boot menu using type Windows 8.1. You'll now have a Multi-Boot menu for all OS's, but the drives will still remain independently bootable, whereas if you'd installed TP to SSD with the hard drive plugged in, it will configure a Dual Boot which makes the SSD's boot entirely dependent upon the HD.

You should put 7 on the ssd and 8 on the hard drive since 8 boots fast enough on it`s own. Use the bios to choose which OS you wnat to boot to, this keeps them all independent.

You can use EasyBCD to create any boot menu you`d like.

10 is not even worth the effort, just run it in a VM for now.
