Windows Forum / Windows XP / Basics / February 2008Bootable CD disk does not work in DVD drive
Hello, Many years ago I created a bootable CD which pretends to be A:\ drive at the bootup (it boots to A:\ prompt). It was working great for all these years. Now, I have a new computer with DVD drive (DVD +/-RW / CD-R/W) in it and my CD is completely ignored at bootup. I wonder what can be the reason. Other CD bootable disks (vide Windows installation disk) work OK. Jack Give this a try: To make a CD auto run, make a file in the root called Autorun.inf To make one, open notepad and enter these lines replace setup.exe with the file you wish to autorun): [autorun] Open=Setup.exe Save it as autorun, notepad will add the extension .txt, just rename the file to Autorun.INF and drop it into the root when burning the CD. To see examples of this file, just grab any CD that you know autorun's, and explore the root, find the autorun.inf file and open it with notepad to view the contents.

The OP is looking for a bootable CD fix for the DVD boot failure That is valid for the Windows environment I suppose. I am talking about initial stage of booting computer.

Try a new burn if you still have the creation software else extract current cd to .iso then reburn. Can't do any harm. Dave Cohen If it completely ignores it then the boot sequence is set so that the optical drive is not scanned prior to the hard drive(s). Even with the sequence set correctly it's doubtful the CD-ROM will boot. It probably uses drivers that are IDE based and the new PC will likely have SATA so the CD-ROM won't completely boot and fail on detecting the DOS level optical driver. There is a driver to load SATA at a DOS level but requires a lot of work and use of command qualifiers to get it to work. >> Hello, >> Many years ago I created a bootable CD which pretends to be [quoted text clipped - 9 lines] > to .iso then reburn. Can't do any harm. > Dave Cohen Thank you. Your explanation makes sense to me. What about if I burn the same bootable image on the new disk using that drive? Will that solve that problem? Should I use CD ROM or DVD disk? Thanks, Jack > If it completely ignores it then the boot sequence is set so that the > optical drive is not scanned prior to the hard drive(s).

Can't do any harm. >> Dave Cohen The image would still contain DOS mode drivers specifically written for a IDE controller ( Parallel ATA ). Those drivers won't work on a machine where the Optical drive is SATA based. ( I'm assuming your Optical is SATA, not PATA ). Disk type isn't important, either would work but using a DVD-R is wasteful since the original CD was large enough. I've built a Real Mode SATA based optical disk, but the drivers are very chipset specific. My bootable disk is built for an Intel ICH8 for a 965 based chipset. The driver name is GCDRom.Sys. You'll find the driver on the web, but configuring it is anything but easy. > Thank you. > Your explanation makes sense to me. [quoted text clipped - 27 lines] >>> current cd to .iso then reburn.

Fact, my hard drive is SATA but booting from removable media should not involve the harddrive regardless the type it is.
