complete HD erase needed

I need help to completely erase my laptop HD in order to re-install WIN XP Pro. I

have a 8 month old Lenovo 3000 N100 laptop. I get a fatal error ("internal error has

caused this process to fail) when using my install disks (6 install + 1 recovery disk + 1

supplemental disk) with the option “destructive format & restore to factory state”.

After I bought XP Pro from Lenovo to replace Vista Business edition, there was no

sound so I did a no no and installed my copy of XP for my gateway desktop on the

laptop which now boots ok but is only good for 30 days unless a multiple liscense is

purchased. I believe if I can get back to a clean install of XP Pro, I can then solve the

audio problem.
At this point, Lenovo sent me to a site to download a version of PC Doctor for Dos for

my machine but won’t tell me how to use it. I think I’m supposed to somehow use PC

Doctor with burning SW (I have Nero & Cyberlink Power2Go) to create a bootable

CD (or DVD?) and then use it to boot my laptop and hopefully see an option to

completely wipe the HD clean. I can locate the ISO file but don’t know how to use it to

create the boot disk. Also, I have to create the boot DVD on my desktop since I don’t

have the SW, that I know of to burn a boot disk on my laptop.
Any help is appreciated.
By the way, there’s more tragic-comedy to this story due to bad advice from tech.

support and frustration on my part.

it sound like your having fun there

as for burning a .iso file to CDr / CD-RW you could go here

but, when i used XP i used Nero & CDburnerXP Pro (i think)

with Nero just download & unzip one of these tutorials, if you require any more help just ask

BTW: winzip will probably be required unless you are using some othe decompression software

Edit: & you may wish to use gparted LiveCD (bootable CD linux distro) to remove all partitions from your HDD
