i don't understand your question man
it is not related to ubcd support or troubleshooting
if your cd rom doesn't read any disc,
why do you try booting on ubcd?
and if your laptop boot on network
you need a dhcp server, then an image server (MICROSOFT RIS)
or a ghost server (assuming that you did a ghost backup of your vaio)
DID YOU TRY MANUFACTURER RESTORATION FROM CD OR HIDDEN PARTITION?
DID YOU TRY TO PLUG A USB CD/DVD PLAYER TO BOOT ON?
A SOLUTION WITH EXTRACTING DISK
you can buy an usb to sata/ide 2.5 3.5" adaptor
http://www.rueducommerce.fr/Accessoires ... SATA-2.htm
then extract your sony hdd to plug it on the adaptor
then boot on another pc with this system
make 2 partitions
1 system
2 data
create a folder d:\xp
copy all the content of xp cd into d:\data\xp
put your vaio hdd back
boot on a win98 floppy disc with smartdrv loaded
A SOLUTION WITHOUT EXTRACTING DISK
you create a dos floppy disk
where you load your nic driver
then access to a network drive
on the other pc - you share a xp folder where you copied all the content of xp cd
you boot on floppy
you copy to your vaio 2nd drive d:\data
ASSUMING THAT YOU KNOW DOS SHELL
