I have Windows 7 successfully installed on an older computer, where it runs quite nicely, but I wasn't able to install Windows 7 by booting from the DVD. I first had to install Windows XP SP2 and run setup within XP. Attempting to boot from the DVD produced the following error message: "CDBOOT: Cannot boot from CD - Code: 5." I tried every method I could find to overcome this problem and nothing worked; I could not create a bootable DVD. If I got past the code 5 error, either the process stalled or I got the error "NTDLR is missing—even using the boot files from a Windows 2000 installation disc." Finally, I discovered the apparent root of the problem when I got this error message, "This disc contains a 'UDF' file system and requires an operating system that supports the ISO-13346 'UDF' file system specification," by booting from a floppy using Gujin Linux.
Unfortunately, when I tried to create a system repair disc, the same errors occurred. Does anyone know how to create a Windows 7 system repair disc that does not require ISO-13446 UDF support but rather will work under an older standard? (This computer will boot from a Windows 2000 or Windows XP SP2 installation CD with no problem. I can't, by the way, run system repair from a USB flash drive because the motherboard supports only USB floppy emulation and not hard-drive or optical disc emulation.)
