If this was at the shop I'd try our USB DVD drive and re-test that XP CD to see if it was actually bootable. The cheap fix is to replace the drive. CDROM drives for laptops are found for 5 bucks and DVDRW drives cost about the same as external drives.
The internal DVD drive of my laptop is broken. It is detected but doesn't work. I would like to reinstall my OS (Windows XP pro) using the Samsung external usb DVD drive that I have. How am I to boot from an external usb dvd drive ? Is there any software that can make my bios detect my external drive ?
__________________________WHAT I TRIED______________________________
I changed my boot sequence and listed the usb storage devices in the top. However, when I pressed F12 to boot from the external usb drive it didn't list the drive.
Then I tried disabling all the devices except the USB storage devices in the boot sequence and it generated an error saying the device couldn't be found.
