I have written a short blog post about how to install Windows 8 on a HP TouchSmart TX2.
I don't have a solution for the cd/dvd problem other than installing from a previously installed Windows 7.
i downloaded a good iso, then i googled for the download link for the utulity app on the microsoft store. it's a free download and it will put an iso on a usb thumb drive it makes it bootable.
then i took that to the laptop and made sure that in the TX bios the usb / floppy boot was enabled.
then i booted off the thumb drive.
time to copy the files and format the drive was about 8 minutes.
then about 4-6 minutes for windows to finish and go to the start screen / ask for a username and password to be entered.
thouch is not right but the stylus works ok.
