Re: error code 0148
not always !!! i got it.
here is the procedure;
during booting, i activate the BIOS setup and then disable all drives except CD/DVD in the system tab and assigned as first priority to the same. Then insert the vista installation dvd and save & exit the bios. NOW THE DVD WORKS WELL WITHOUT ANY PROBLEM. After changing the primary settings such as language and time zone, I've activated repair mode. Then proceed by agree to "remove the recently installed some programms which changes the default settings". Within minutes it restart again and now work well. the repair mode removed the daemon tool.
so bfor install such programms it should be check the bios whether the cd drive has got the 1st priority and remove/degrade if it has....
