installer like Wubi for windows 8

Question

I want to install windows 8 on my windows 7 machine but the problem is I can't make a new partition because there is a limit of 4 partitions at the most which I can't cross. To install windows 8 I would have to remove a partition but I want to know if there is any program like Wubi which help me installing windows 8 inside windows 7, as ubuntu is installed inside a windows computer by Wubi.

PS:I know about virtual machine and softwares like that but the problem is if I run windows 8 in virtual machine, I won't be able to allocate full system resources to windows in virtual machine. However that isnot the case if I install windows 8 like we install ubuntu with Wubi, because it would be listed in boot list.

I will be very thankful to you.

Answer 1

What you're looking for is called booting from a VHD (Virtual Hard Disk). Assuming you have Windows 8 Pro, you can install it in a VHD file on your hard disk and boot from it as if it were installed on its own partition.

See this article for instructions (they're for the Developer Preview, but should apply to the RTM version as well).

If you have regular (non-Pro) Windows 8, you can try a program called VBoot, which should support any edition of Windows. They don't explicitly list Windows 8 support, though.

Answer 2

You could always set up a virtual machine using a program like VirtualBox, and then install Windows 8 on that.
