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?

You'd have to get a bit of background: I've built a high spec computer. In Windows Index it is 7.5 + for all but the hard drive.

I have been experimenting with a RAM disk inside Windows running virtual machines 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 there is an image of what's supposed to be on the RAM disks but the methods below haven't seamed seamless though.

As at boot I would like to take an image and put it into RAM, save it to an HD often so I don't get a corrupted system and can use it as a day to day computer.

A live CD that is dynamic. I don't want an OS specific set to running in RAM like bartpe and Ubuntu. I want a normal computer OS 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.

If these answers are not exactly what you are looking for, you may need to explain further what it is that you are trying to accomplish. An operating system does not "boot into RAM" in the first place, so it is not clear what you may be referring to.

Do you want an OS to boot FROM RAM? If that is the case, then it is not possible unless another operating system is hosting it.
