I run WinXP Pro and have recently installed a new hard disk. My partitions are as follows and are in order of creation....... Disk 0 - C: 10GB Primary NTFS - OS XP Pro Disk 1 - D: 12GB Primary NTFS - No OS E: 25GB Primary NTFS - No OS Z: 1GB Primary FAT32 - Command.com/Autoexec.bat, and NTFSDOS.exe I have added the following line to the boot.ini file under the OS section....... Multi(0)disk(1)rdisk(0)partition(3)\windows="MS-DOS" As you can probably tell, I am trying to add a boot menu option to boot into DOS on the FAT32 partition with an NTFS reader invoked in the autoexec.bat file. Unfortunately, it doesnt work, as when selecting MS-DOS from the boot menu I get a message that it can't boot due to a harware problem/configuration issue, and to check the boot paths etc. Can anybody help me solve this problem?
