I would like to know whether and how you can setup a computer to boot into RAM. I have 16GB of DDR3 1600MHz RAM.

Could it be done in Windows? If not, maybe in a light version of Unix?

yout to get a bit of back ground i built a high spec computer windows index it is 7 .5 + for all but the hard drive i have been expermenting with ramdisk inside wihdows running virtual macciens with great success i was woundering if you could boot a enviroment in a computer Directly in to a ram disk as its primary hard drive from what i have seen is that thire is a img of whats suppost to be on the ramdisks but the although methods below havent seamed seamless as at boot i would like to use a to take a img and put it in to ram save it to a hd offten so i dont get a corrupted system and can use it as a day to day computer

a live cd that id dynamicthat changes i dont what a os specifc set to running in ram like bartpe and ubuntu i whant a normal computer os to to be set in to ram

It appears that "yes, it's possible", see related info (off-site): Windows 7 RC x86 in 4.75 GB RAM disk. Perhaps try some stuff out and come back with specific questions? – techie007 Oct 31 '11 at 16:45
Thank you I was hoping for something free but I will give it ago – Robert Slinger Oct 31 '11 at 16:46
I believe UBCD4Win boots up with a ram disk. Not sure exactly what you are trying to do here, but it may be worth investigating: ubcd4win.com – sbtkd85 Oct 31 '11 at 16:57

16GB of disk space would be a bit light for Windows proper, so I wouldn't recommend trying. (Windows PE, on the other hand, boots into a RAM disk by default.) – Harry Johnston Oct 31 '11 at 20:38

You may want to give KNOPPIX linux a try:

Knoppix is a Live Linux CD / Live DVD based on Debian GNU/Linux

Specially the boot option toram

At the boot prompt, type "knoppix toram". Knoppix will load the contents of the CD into ram and run from there. After boot up, the CD can be removed and the cd drive will be available for other uses. Because this will take up a lot of ram, it is recommended for those with at least 1 GB of ram.

Notice that this (in theory at least) can also be done with the DVD version.

If you want to try something similar on Windows the livecd distribution MINIPE (no link, sorry) may do the trick, but I am not really sure about the legal issues that using it may imply.
