New motherboard, reinstalling windows

[woopsi]

So i wanted to change a gpu and i ended buying and a new motherboard. Thing is when i can't find any proper windows 7 iso so i can reinstall. Would it work if i download the windows 10 iso again? I'm asking because before the new motherboard i had windows 10 already and i don't know if have to use the serial key which i don't have since i had bought the computer 4-5 years ago. Also the bios on new motherboard is different and i'm currently using elementaryOS(linux).
Motherboard is ASROCK h61m-vg4
Thanks in advance.

Since you have a new motherboard windows 10 will want a new licence key. windows matches itself to your motherboard and unless the replacement is a very similar model, there is a big chance you need a new licence. you can install it and see and try to contact Microsoft but big chance you have to buy new key.

Win10 is free until july, isn't it? Also, i can't enter to my account via log in screen since keyboard/mouse work only in bios which means i can't reinstall via the windows tool. I found some win7 iso but they didn't work and now i download win10 iso, will win10 is already install but i want to reinstall. That's what i want to ask, if this will work

win 10 is free for upgrades from win 7 or win 8, but yours isn't an upgrade. Yours is a new pc in Microsoft's eyes.

Unless your win 7 or 8 were retail copies then your old install is forever linked to your old motherboard.

If they are retail copies, then yes, you can use a win 10 iso and clean install it on the new board using http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html

what is new motherboard? there should be settings to enable USB in bios to let you type.

As i said before it's an asrock h61m-vg4. I tried to search for the options but didn't find it since it's different gui than the old fashioned bios i had on my previous motherboard. So, what are my solutions now? Buying new windows key?

sorry, i was blind and didn't see motherboard in original post.

according to page 58 here: http://asrock.pc.cdn.bitgravity.com/Manual/H61M-VG4.pdf you should have 2 USB slots working, but you have to use the ones on back of case as only usb 2 will work in setup

As for windows, best option is buy a retail copy of win 10 and then next time you can move it without getting a new licence.

Well, i think i can use linux too but if I'm not wrong new drivers(gpu/mobo) are for windows which means i need to buy windows.
Thanks for your time, in case someone has an alternative idea, drop it.
Thanks again
