(1)- In 2005, I bought a computer, Acer Travel Mate 2303LCi. On its HDD of 40 GB, Windows XP is installed in a partition of 20 GB.

(2)- I put the computer ON and inserted a Puppy Linux 4.2 Disk 1 - Live CD. The computer acknowledge the insertion of the disk as it would do for any other disk. I restarted the computer. Same result.

(3)- I tried the same procedure with a Dell Inspiron computer in which the Windows Vista Home Basic 32 SP1 has been replaced by a Ubuntu 9.10 which is performing well. Puppy Linux could also perform well with the Live CD.

(4)- I went back to the Acer computer and succeeded in installing a Ubuntu 9.04 in the part of the HDD not used by Windows Vista.

(5)- Always on the Acer computer, I then tried to install Live Puppy, this time, using Ubuntu 9.04. The result was the same as in (2).

(6)- Always on the Acer computer, I made many different attempt to remove Ubuntu 9.04. They were all unsuccessful.

(7)- Could someone, please, give me some advice on how to remove Ubuntu 9.04 and operate with the Pyppy Linux live disk on the Acer computer.

Thanking you in advance.

I have found the newest puppy 4.3.1 to have the best hardware support. You could also look at 4.1 or 4.2 with retro kernels which may be better for the older stuff. As far as removing a distro, simply format the partition with gparted available in ubuntu and puppy.

ftp://ftp.nluug.nl/ftp/pub/os/Linux/distr/puppylinux/

What result was that?

You didn't say what the result was in step (2)

To remove a Linux distro like Ubuntu, you just reuse the partition. If your having a problem with the dual boot, and possibly overwrote the XP boot manager so it only boots into Ubuntu, you might have to reinstall the XP boot manager with the Windows XP recovery disk. But you haven't explained what the problem is. You mention same result, but we don't know what that result is.
Puppy will boot off the cd and install itself into the memory of the computer and run from memory. That is, if your booting successfully from the CD.

You install Puppy from the Puppy menu after booting up the Puppy CD, why would you try to install Puppy using Ubuntu?

Did you possibly install Ubuntu using Wubi, which installs Ubuntu within Windows, and that is what your talking about?

We would like to help, but we need to know what your problem is, you didn't make that very clear. Start in Step (2), when you restarted the computer, what did you see? Windows? Ubuntu? Windows or Ubuntu with an icon showing the CD?

If indeed you have installed Ubuntu through Wubi and need to edit partitions, take a look at the GParted Live CD - it allows for nearly any type of partitioning operation on your hard drives. The only thing I've ever found it lacking in is LVM handling.

First- Set The BIOS to boot from CD and have the CD in there everytime you want to use Puppy.
Second- in the Software Portal(or whatever its called now, i am now running gOS) Install Virtual Box of M$ Virtual PC and mount the ISO and Puppy will run inside Ubuntu
This will be faster than the CD, and BTW did you burn the ISO with a ISO burner cuz that may be the problem if you didnt
