Hi, if you still want to do this, please take the time to read through my post - I think you'll find it is worth it
No, I've heard that it is possible if you use a grub entry something like this
title Boot from iso on a harddisk (Dangerous - testing)
map (hd1,0)/isofilename.iso (hd2)
I haven't tried it, and I think someone said it was potentially dangerous. , but I can't imagine what could be dangerous about it. I think they said the iso couldn't be in any folders or anything either (i.e. put it straight in C:\)
If you don't understand any of that code, I can try to explain it to you, but you would be better off either:
1 - burning the iso to a cd and booting from that, or
2 - doing what we call a "frugal install". Puppy and Grafpup are designed to be run from CD, saving settings and anything you change in one file on the hard drive or a flash disk or something (yes, you can run from a multisession disk and other stuff too, but most people don't).
If you decide to install them to a hard drive instead of running from CD, you are given two options. One is a traditional install that uses its own partition(s). The recommended way is a frugal install, which puts several files from the CD in an existing partition (windows or linux), and runs from them. Because all your settings and stuff are in one file, it is very easy to back stuff up, and to upgrade to a new version. With a frugal install Grafpup will also still be very fast because it will load into RAM like from the CD.
Although it is normal to run from a CD and then use the installation wizard, it is very simple to to a frugal install without burning a CD. I have never burned a CD of Puppy or Grafpup because I couldn't be bothered burning a CD every time I wanted to try a new version. Here's what to do:
1 - open the iso file with something like Winzip or Izarc (Izarc is free)
2 - extract graf_200.sfs, initrd.gz, vmlinuz, and zdrv_200.sfs into C:\
Then you need to find a way to boot into Grafpup. You can use WinGRUB to install Grub to your hard drive or a floppy disk if you're afraid of touching Windows, and then use this GRUB entry:
title Grafpup 2 inside C:
kernel /vmlinuz root=/dev/ram0 pmedia=idehd
Or you can go somewhere like http://www.icpug.org.uk/national/lin...p01-4steps.htm
and find out about adding an option into the Windows boot system, so you can choose at startup to boot linux.
