I know it has been discussed before in previous threads, but I have yet to find an answer. I have created a custom bootable DVD with Winodws Xp SP2 Windows Xp SP1 Windows 2000 Advanced Server Windows 2000 DataCenter Server Windows 2000 Server Windows 2000 Pro Windows Millenium Windows 98 SE Ive gone through the entire guide as it instructs with minor directory name changes. I have modified the chshell.ini to fit my own pre boot menu needs, very basic not that comfortable with cdshell, but debugging it seemed to work fine. When I try to boot from the DVD I get the error. Error Booting From Disk Please Reboot. I have also tried to build it with Ultra Iso and Easy boot with bootloader from my cd's and bootloaders from bart page, but if I build it with those programs I get a quick read of the dvd on startup and skips right into booting Windows XP. I have tried different media and tried settings like omit iso 9660 options and enable lowercase settings all with no success. The only one that seems to be almost working and trying to boot is using cdshell, again though no sucess error booting disk please reboot. If anybody has any suggestions it would be greatly appreciated. I have a very good understanding of computers and programs, kinda a closet geek. I get a little frustrated with programming type stuff, I had to be very patient with chshell, ended up modifying sites example to suit my needs, worked out better for me than trying to write one from scratch. I appreciate the help NateDawg cdshell.ini
