I purchased Windows Vista (on four CDs, not a DVD version) and installed it on the computer as my only operating system. After installing it, I found that the CD-Rom drive is not read, such that it is receiveng power from the power cable and data from the data, because when I right click on the CD-Rom drive and click on eject, the tray of the CD-Rom gets opened. I tested the CD-Rom on another computer which has Windows XP as an operating system and it was working. I decided to reinstall Windows XP again on my computer using a bootable CD but I found that during copying the files needed for installing windows, the computer has a problem of being unable to copy some files, particularly ".xml" files, thus the windows cannot be installed. The whole picture now is that I don't have any operating system on my computer
. Of note, my CD-Rom is approximately 5-6 years old and I have been using it frequently and it is ASUS 52X
