Upgrading XP Home to XP Pro on acer aspire revo issue

Hi there,
I recently purchased the acer aspire revo nettop that comes with XP Home. I want to upgrade it to XP Pro for networking purposes. I have a full valid XP Pro disk, its sp2. Now the revo has Home SP3. I know that you can't upgrade an SP2 on a SP3 machine, So to install, I used nLite to slipstream sp3 on to my XP Pro disk and it appeared to work correctly. Now I start the process and it gives me the option to upgrade and things start off correctly until it comes time to reboot. When it reboots I get an Chk Disk Error. Press Ctl, Alt, Delete to restart. I do this and no luck. Now when I reboot the machine its says ' select which operating system to load" XP Home or XP Pro setup. Everytime i select XP Pro setup the same error message appears. I am using an external DVD drive to run the software. I also changed the boot options to do the external drive first. Also I read somewhere that I need to change the bios to go from Sata to active IDE, which I also did and no luck. I have read that others have successfully been able to load XP Pro on to the machine. I hope I can.

Thanks for your help.

If you are connecting the External drive via USB you might check for a "Boot from USB" option in the BIOS.

unfortunately that didnt work. When in the bios boot options it already reads the external drive as a USB peripheral. Also I was wrong on the error. its says "disk read error" not chk disk error. Thanks for your help. Also I am going to try and create another disk through nLite. maybe I messed up somehow. I will keep you posted.

Thanks,

Because it gives you the option to boot either XP Home or XP Pro, I assume that you did not wipe your existing installation.

I have always been prone to formatting the hard drive. If data is not an issue, I would go that route. You will have a cleaner final product. If you have data, get that to a USB drive or another computer first.

If you can run XP Home, XP Pro should work as well with the SATA setting in the BIOS.

How do I wipe my existing installation? and I would rather do the upgrade route as opposed to a format and new install. I read that others were able to successfully install xp pro as an upgrade. Please let me know if there is anything else I can try.

Thanks,

You will need to go into your BIOS and set it to look for your USB drive BEFORE it looks for your hard drive. Usually, there is a place where you can set IDE settings. You would be looking for a "boot order", or something like that.

As a option (like Dell) sometimes you can make that choice using an "F" key at the beginning of the boot process, before XP starts.

Once you can boot off the DVD, you should be able to start the XP install procedure.

It will walk you through the process and get you to the point where it addresses your hard drive. Delete ALL partitions. Then create a new partition that is the size of the whole hard drive. After that, follow the prompts to do the XP install.

NOTE: Once you delete the partitions in the hard drive, your computer will be inoperable until you get the XP install completed.

I was able to successfully upgrade the operating system to XP Pro, thus allowing to keep all of my XP home settings in tact. I had to 1.) Create a new nLite cd that included nvidia sata drivers, 2.)change the bios to boot to cd-rom and 3.) change the sata bios setting to "active ide".

Thanks for your help.
