Oxc0000225 boot fail after resizing storage drive want to duel boot

Hi i want to duel boot windows 7 and windows 8.1...i have a 240gb ssd with windows 7 already installed on it....i also have a 2tb storage hardrive and i use this for storage..btw this hardrive did have my windows 7 on it untill i bought the ssd then i ported windows 7 on to the ssd using Paragon Migrate OS to SSD...then i formatted the 2tb drive and have it as a storage drive now.

Ok so my problem is when i split my 2tb storage drive into 2 partitions using AOMEI Partition Assistant Standard Edition ("i intend to use the one partition of about 750gb for windows 8.1") ..however my computer will not boot anymore? i get a Status Oxc0000225 The boot selection failed....i belive this is because the storage drive still has the mbr on it from when it had windows 7 on it...in fact i know it is still on there but i dont know how to delete the mbr from the storage drive???

If i split the storage drive into 2 partitions the computer will not boot....if i disconnect the storage drive and boot with only the ssd it will boot again my pc boots again....also if i rejoin the storage drive back to one partition and reconnect it..it boot fine with it connected again....so there for some reason windows on C drive does not like my storage drive having a different size or being 2 partitions and it appears it needs some information from the storage drive if conceted to be able to have successful boot??... could this have something with the old MBR on my storage drive from when windows 7 was on it?....my questions are as follows

1..Can i delete the mbr from the storage drive....and if so how and with what software

2..does my storage drive need an mbr?

3..my storage drive is 2tb i was going to use around 750gb for windows 8 in a new partition the other partition will have data in it from downloading films etc that i dont want to lose....so if i delete the MBR from the storage drive will i lose this data?

Also the only way i could get my C drive to reboot again with the storage drive...was to make a boot disk and rejoin it with partition magic boot disc....and set from a primary drive to a logical drive...what difference does this make?....and can i ever restore that drive back to a primary drive?

Many thanks for any help

Thanks for your reply you have answered some questions i had...however maybe the main question i would like ask is how do i partition my storage drive and maintain a stable boot without the Oxc0000225 boot fail?....and once someone has helped me with that problem is it just a case of installing windows 8.1 onto the free clean partition i have just created and be able to choose which operating system i want to load during a boot up...this is my goal and the Oxc0000225 boot fail is the problem....any help to get to my goal would be most welcome
