Windows 7: How to dual-boot Windows 7 with an older version of Windows NT?

How to dual-boot Windows 7 with an older version of Windows NT?

Hello, everyone.

I've been trying to dual-boot (Sorry most of my questions are on dual-booting) Windows 7 with Windows NT 4.0. My one problem is that while it's starting, it says
STOP: (forgot error code...) INACCESSIBLE_BOOT_DEVICE
I thought that since Windows 7 is Windows NT, that it would work. Guess it didn't.

Is there anything I did (or am doing) wrong?

Any help would be greatly appreciated.

Yeah, you will have a BIG driver problem. Why don't you use Virtual Box. There it will run.

Make sure you wipe the disk, then start with NT, then install windows 7. Maybe partition the disk first using something like GParted on a LiveCD.

I hope my answer helped you resolve your problem. If you have any further questions, please feel free to contact me at:

OK, since this obviously won't work, does anyone know how to... maybe install it to an external hard drive or something?
