What happen to WinLinux? I went to their website, looks like the OS is not being updated? Still WinLinux2003? The same with PhatLinux.
The good projects live on and gain support The poorer ones hibernate and die. Find a different one @ http://distrowatch.com/ or @ https://sourceforge.net/
There's also Lindows, but it's kind of a strange distro IMO - the installs are packaged by the vendor and you can "subscribe" to their package list. Not sure if you can do your own custom configure things, but it seems a little hoaky to me. Probably best for a linux newbie or an organization migrating to linux to save on OS costs.
Tried ReactOS live cd. Didn't work on my machine. The error message: A problem has been detected and ReactOS has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: ntoskrnl.exe KMODE_EXCEPTION_NOT_HANDLED
I've heard some good about Lindows though I don't know about ReactOS, it's supposed to be compatible with Windows.
Connect, you can test drive it the way it's intended to: through a hardware simulator (also known as a "virtual machine") such as VMWare (commercial), QEMU (free) or Bochs (free). Pretty much all development on new operating systems happens on these hardware simulators (it gets tedious rebooting your own computer to check if the one-line code change you made crashes the computer or not... ). It's therefore somewhat natural that there are bugs which sometimes prevent the OS from booting on real hardware. If you're interested in the project I'm sure the developers would appreciate a bug report detailing your hardware.
